LTB FAMILY
ABB has over a century of experience in developing,
testing and manufacturing high voltage circuit
breakers. Through the years, our circuit breakers
have acquired a reputation for high reliability and
long life in all climates and in all parts of the world.
ABB’s LTB circuit breaker family, with rated voltage
72.5-245 kV and breaking current up to 50 kA,
satisfies the highest demands. It is based on latest
developments in dielectric dimensioning and arc
physics research.
ABB produced the world’s first SF6 circuit breakers
with arc-assisted interrupters in the mid-1980’s -
Auto-PufferTM.The energy required for interrupting
short circuit currents is partly taken from the arc
itself,significantly reducing the energy required
from the operating mechanism. Lower operating
energy inherently reduces mechanical stresses,
on the circuit breaker itself as well as on the
foundation, and increases circuit breaker reliability.
For many years, ABB has used operating
mechanisms with energy mechanically stored in
springs. This solution offers considerable
advantages in that the energy in the tensioned
springs is always available.
The design of the LTB is a well-proven technology
(over 20,000 units are in service).

When interrupting high currents (e.g. rated short-
circuit current), Auto-PufferTM interrupters show the
advantage they were designed to provide.
On opening, the operation of an Auto-PufferTM
interrupter at high current begins the same way as
a puffer interrupter. It is not until after arcing begins
that a difference in the operation principle is seen
between the high and low current interrupting
cases.
When the arcing contacts part, an arc is drawn
between the moving and stationary arcing contacts.
As the arc flows, it to some degree blocks the flow
of SF6 gas through the nozzle. The arc drawn is
extremely hot and radiates a lot of heat and begins
to heat the SF6 gas in the interrupting gas volume.
Thus, the pressure inside the Auto-PufferTM and
puffer volumes increases due to the rise in
temperature as well as due to the com-pression of
gas between the puffer cylinder and stationary
piston.
Gas pressure inside the Auto-PufferTM volume
continues to increase until it is high enough to force
the Auto-PufferTM valve to the closed position. All
SF6 gas required for interruption is now trapped in
the fixed Auto-PufferTM volume and any further
increase in gas pressure in that volume is due solely
to heating from the arc. At about the same time,
the gas pressure in the puffer volume reaches a
level sufficient to push the overpressure valve open.
Since the gas in the puffer volume escapes through
the overpressure valve, Design Features Auto-
PufferTM Interrupters there is no need for a high
operating energy to overcome the compression of

Auto-PufferTM
SF6 gas while at the same time maintaining the
contact speed necessary to withstand recovery
voltage.
When the current waveform crosses zero, the arc
becomes relatively weak. At this point, the
pressurized SF6 gas flows from the Auto-PufferTM
volume through the nozzle extinguishing the arc.
When interrupting low currents, Auto-PufferTM
interrupters act in much the same way as puffer
interrupters. That is, there is not sufficient gas
pressure generated to force the Auto-PufferTM valve
closed. Thus, the fixed Auto-PufferTM volume and
puffer volume form one large puffer volume. In such
a case, the SF6 gas pressure required for
interruption is built up by mechanical means as in
a puffer interrupter. Unlike a puffer nterrupter,
however, Auto-PufferTM need only mechanically
generate sufficient gas pressure to interrupt a
Design Feature Auto-PufferTM Interrupters
portion of the rated short-circuit current (i.e. 20%
to 30%)
In the open position, there is sufficient distance
between the stationary and moving contacts to
withstand rated dielectric levels.
On closing, the refill valve opens so that SF6 gas
can be drawn into the Auto-PufferTM and puffer
volumes.Because interruption of low currents
requires only moderate build up of SF6 gas pressure
by mechanical means and since high current
interruption uses heating from the arc to generate
necessary gas pressure in a fixed volume, Auto-
PufferTM interrupters require far less operating
energy than puffer interrupters (i.e. about 50% less).
ABB Auto-PufferTM interrupter is also a single
motion design.

LTB Design Features and Advantages
Design Features
LTB is available for single- or three-pole operation.
Design Features and Advantages
For circuit breakers with one breaking element per
pole, both modes of operation are possible.
For three-pole operation, the circuit breaker poles
and the operating mechanism are linked together
with pull rods. On every pole there is an individual
opening spring controlled by the pull rod. There is
however one exception. In the LTB D three-pole
operation case there is only one opening spring
cntrolling all three poles and it is mounted on the
pole furthest away from the operating mechanism.
Each circuit breaker pole constitutes a sealed SF6
filled unit, which includes the breaking unit, the
hollow post insulator and the mechanism housing.

LTB FAMILY
The three poles of the circuit breaker can be mounted
on individual pole supports or in the case of LTB D on
a common support frame (pole beam).
BLK is used for:
LTB D 72.5-170 kV
LTB E 72.5-245 kV Single-pole operation
BLG is used for:
LTB E 72.5- 245 kV Three-pole operation
The operational reliability and the service life of an
SF6 circuit breaker is very much dependent on the
ability to ensure sealing of the SF6 gas volume and to
neutralize the effects of moisture and decomposition
products in the gas.
• The risk for gas leakage is negligible; double nitrile
rubber O-rings and X-rings are used with excellent
result.
• Each breaking unit is provided with a desiccant,
which absorbs the moisture and the decomposition
products from the interruption process.
• Since the interrupting capability is dependent on the
density of the SF6 gas, the LTB circuit breaker is
provided with a density monitor.The density monitor
consists of a temperature compensated pressure
switch. Therefore, alarm signal and blocking function
are activated only if the pressure drops due to
leakage.
The design corresponds with the demands in the
standards IEC and ANSI. Special design solutions to
meet other standards and/or specifications are also
available.
Current Switching Capability
All LTB circuit breakers are capable of interrupting
short-circuit currents in a maximum of 40 ms. We can
also guarantee restrike free interruption of capacitive
currents due to optimized contact design and
movement.
For inductive current switching the over-voltages are
low as a result of optimum quenching at current zero.
Dielectric Strength
LTB has high dielectric strength even at atmospheric
SF6 pressure, due to optimized contact gap.
Controlled Switching
As option LTB circuit breakers can be used for
controlled switching by applying our controlling device
type SwitchsyncTM.For further information please see
chapter O-1�Controlled Switching�.
Stable Operating Times
For controlled switching it is of the utmost importance
that the functional times for closing and tripping
operations are constant. We can guarantee � 1 ms
for all LTB circuit breakers.

Design Features and Advantages
LTB FAMILY
Material
The selected components of aluminum (mechanism
housings, HV-terminals, cubicles) give a high degree
of resistance to corrosion, without the need of extra
protection. For use in extreme trying environments
LTB can be delivered with a protective painting.
The support structure and protective tubes for the pull
rods are made of hot-dipped galvanized steel
Insulators
LTB circuit breaker is as standard delivered with
insulators that consist of high-grade brown-glazed
porcelain or composite insulators (light gray). LTB
with light gray porcelain can be delivered on request.
LTB is available as standard with long creepage
distances.
Longer creepage distances can be quoted on
request.
Mechanical Strength
The mechanical durability gives a sufficient safety
margin for normal wind loads and static and dynamic
forces from conductors.
Seismic Withstand Strength
All LTB circuit breakers can in their standard versions,
withstand seismic accelerations up to 3 m/s2 (0.3 g),
LTBD up to 5 m/s2 in accordance with IEC 1166 and
IEEE 693.
Rating Plates
A rating plate, which includes data for the circuit
breaker, is placed on the operating mechanism
cubicle. The rating plate is made of stainless steel
with engraved text.
Operating Mechanism

Design Features and Advantages
breakers for more than 30 years with excellent service
record at varying climatic conditions.
The SF6 gas leakage is less than 0.5% per year.
SF6 Density Monitoring
Since the interrupting capability is dependent on the
density of the SF6 gas, the LTB circuit breaker is
provided with density monitor(s).
The density monitor consists of a temperature
compensated pressure switch. Therefore, alarm signal
and blocking function are activated only if the
pressure drops due to leakage.
The standard version of LTB D for 72.5-170 kV has
one common density monitor for all three poles.
Alternatively LTB D can be provided with one density
monitor per pole.
All LTB E circuit breakers have one density monitor
per pole.
Climatic Withstand
The LTB circuit breakers are designed for, and are
installed in, widely shifting conditions from polar to
desert climate throughout the world.
For circuit breakers installed in areas with extreme low
temperatures there is a risk of condensation of the
SF6 gas. In order to avoid condensation
consequences, one of the following gas-mixtures is
used:
• SF6 and N2
• SF6 and CF

Support Structure
Support structures are included in the standard versions
of the LTB circuit breakers. The support structures are
made of hot-dipped galvanized steel. The standard
versions for structures are:
• LTB D 72.5-170 kV One support column per
• LTB E all types One support column per pole
• For detailed information see “Dimensions”
The support structures are prepared for connection to
ground by means of drilled holes on each leg.

standards. Other dimensions (e.g. DIN) by means of
adapters, are available on request.
Circuit breakers with vertically mounted breaking
elements have terminals on both sides for connection
in either direction.
Circuit breakers with horizontal breaking elements have
one terminal per breaking element. The terminals are
directed upwards.

Controlled Switching Devices
The goal for controlled switching is to increase power
quality in the network systems by reducing switching
transients. All LTB circuit breakers are suitable for
controlled switching with ABB’s SwitchsyncTM device.
In order to obtain optimum result the switching instants
should be different for the three phases. For three-pole
operated circuit breakers this is achieved with
mechanically staggered poles.
Presently more than 1,000 HV live tank circuit breakers
manufactured by ABB are in operation with controlled
switching.
Type Tests
The LTB circuit breakers have been type tested in
accordance with IEC and/or ANSI standards. Type test
reports can be presented on request.
Routine Tests
All LTB circuit breakers are routine tested before delivery.
Our test program complies with IEC and ANSI standards.
Transport
The LTB circuit breakers are normally packed and
transported in seaworthy wooden crates.The circuit
breaker poles with one breaking element per pole are
transported as com-plete units.
For circuit breakers with two breaking elements per pole,
the breaking elements and the support insulators are
transported in two separate cases.
For detailed information regarding weights and
dimensions see “Shipping data”.
Breaking elements as well as support insulators are filled
with SF6 gas at a slight overpressure.
Arrival Inspection
On arrival the packaging and contents should be
checked against packing list. In the event of damage to
the goods, contact ABB for advice, before further
handling of the goods takes place. Any damage ought
to be documented (photographed).
SF6 gas
Gas for filling up to rated pressure can be delivered in
bottles, each containing 40 kg gas.

Design Features and Advantages
LTB FAMILY
Erection and Commissioning
Assembly instructions are provided with each delivery.
Erection work at site can be done in 1-4 days depending
on LTB type and size.
Filling of SF6 gas to specified rated pressure is done by
using the following pressuri-zing equipment, which can
be delivered on request:
• One special control valve, for connection to the gas
bottle, and a 20 m gas-filled hose with connectors.
• A complementary control valve for connection to CF4
or N2 gas bottle (for mixed gas filling).
When using above equipment gas filling can be carried
out without gas being released into the atmosphere.
For illustration of gas filling equipment see page I-6.
Maintenance
LTB is designed for a service life of more than 30 years
or 10,000 mechanical operations. For current switching
the number of operations before service is dependent
on the interrupted current and type of application.
Inspection, maintenance and overhaul should be carried
out at regular intervals de-pending on the ambient
conditions and the number of operations.
The general actions are described below:
• 1-2 years: Ocular inspection
• 7-10 years or 2,000 mechanical operations: Extended
ocular inspection and some lubrication of the operating
mechanism(s)
• 15-20 years or 5,000 mechanical operations Preventive
maintenance including general inspection of the circuit
breaker and operating mechanism. Operation test
including measurement of operating times and possible
adjustments.
• 30 years or 10,000 mechanical operation: A
comprehensive inspection is recommended to give
increased safety and continued problem-free operation.
The inspection methods and scope depend very
much on the local conditions.
For circuit breakers for special switching duties such as
switching of reactor banks overhaul of the breaking
chamber should be carried out more frequently,
approximately 5,000 operations
Overhaul and repair work must be performed by
authorized personnel only.
The instructions in the manual for operation and
maintenance should be observed.
ABB is available for discussions and advice.
