The Power Conductors & Joints System

ur power conductor material is either Copper ASTM Designation B187 or Aluminum ASTM Designation B236. TECHNIBUS™ conductors are designed

to have sufficient cross section so as not to exceed acceptable temperature limits when operated at rated continuous current or during short circuit conditions.

Maintenance free bus joints utilize splice plates of a special configuration which have a cross-sectional area equal to, or greater than, that of the main bus to improve current equalization.

TECHNIBUS™ joints are manufactured from silver-plated copper or tin-plated aluminum to maintain low contact resistance for long, trouble-free operation.

Adjustable bus joints are provided to compensate for normal installation tolerances and to allow for the removal of individual bus sections without disassembly of adjacent sections.

All joints are assembled with high-strength hardware including heavy-duty, load-bearing flat washers which provide over 4,000 pounds of clamping force per bolt. Bolt patterns are proportional to current rating.

Belleville spring washers are standard for aluminum bus joints. All bus joints are adjustable to compensate for normal installations tolerances.

tandard low voltage bus systems are not insulated. For 600 - 1500V, insulation is optional. 5kV through 38kV

conductors are fully insulated and foil tested in accordance with ANSI/IEEE Std. C37.23, Section 6.2.1.4.

Cycloalaphatic epoxy is standard, using a process which provides the highest quality insulation system available. This provides high dielectric strength, excellent chemical resistance and durable mechanical characteristics. The epoxy is bonded to the busbars thus eliminating air gaps which could initiate corona problems.

*UL & CSA now available for low and

medium voltage applications.

We are ISO 9001 certified. Customer satisfaction, quality and reliability are the essence of our policy. Our standard construction design is in compliance with ANSI/IEEE Std. C37.23 and meets or exceeds the requirements of IEC and CSA.

n today’s demanding industrial world where reliability is expected while maintenance opportunities and budgets are limited, we offer two options which will reduce maintenance costs and prevent problems before they begin.

Our monitor system detects the loss of one or more heaters and power source failures. Heaters can also be furnished with externally readable LED indicators which easily identifies failed heater elements.

Monitor systems and LED indicators can be used separately or in combination. Our monitor systems and indicators are designed to cover a wide range of applications and can also be installed on existing installations.

venting system. The bus duct enclosure is structurally enhanced and designed to withstand an over pressure caused by an internal arc.

everal installation cost advantages are included with our bus systems:

Factory assembled and shipped in lengths up to 19’-10”

Enclosure and bus joints are adjustable to accommodate normal site variations.

5-15kV systems include removable boots for protecting shipping split bus joints. Push-in type fasteners are quickly installed reducing field insulation labor by 90%

No field drilling of enclosures or bus is required for standard assemblies.

Weather proofing is accomplished with adhesive backed, pre-cut gasketing eliminating the need for field applied caulking and sealants.

Enclosure construction utilizes single wrench fasteners for faster assembly.

Several features of the support assembly contribute to its uniqueness. With our patented adjustable assembly, bus supports can be easily added or repositioned without drilling or modifying the enclosure. With this patented design, we are able to offer greater adaptability for the bus duct systems which we provide.

ur patented enclosure design with extruded channels offer strength in excess of common

formed/fatigued sheet-metal construction. The exclusive weatherproof side member design allows the attachment of insulator assemblies and end flanges, and the joining of shipping splits without drilling holes or penetrating enclosure sides with hardware. Our enclosure is made of non-corrosive, non-magnetic, high conductivity aluminum. The enclosure material serves to eliminate hysteresis loss and minimize induced losses resulting in lower operating costs and shielding external structural members from magnetic heating. Consult factory for additional information regarding the

against an extruded slot which prevents hardware from damaging the gasketing and violating the seal integrity. The elimination of bolt holes prevents water penetration to the inside of the enclosure.

Screened breather/drains are provided at all access covers, elbows and along enclosure bottoms to minimize the formation of condensation. Strip heaters are located in proximity to access covers to allow easy inspection. Heater wiring is contained in a factory installed and terminated flexible metallic conduit. Heaters are operated at half voltage for extended life.

Our standard heaters are suited for Class 1 Divisions 1&2 Groups A, B & D. Hazardous area thermostats are optional.

advantages of aluminum enclosures.

We also offer steel and galvanized steel enclosures up to 2000 amps and non-magnetic stainless steel for ratings above 2000 amps. Consult the factory for these options. Totally enclosed, non-louvered construction prevents contaminants from entering the enclosure. Covers are easily removed for access to, and inspection of, bus system elements.

Flexible enclosures and bus support design minimizes the need for expansion joints. Straight runs less than 80 feet do not require special expansion fittings.

Structural supports are designed in accordance with the American Institute of Steel Construction. Supports are designed for nominal 12 to 15 foot spacing and are adjustable to accommodate site variations. Supports are clamped to ducts which eliminate installation alignment problems and field drilling.

Isolated Phase Bus

Please contact your local sales representative to request our complete Isolated Phase brochure.

For Main Generator Leads with current ratings from 3kA up to 50 kA, Isolated Phase Bus is the solution. Isolated Phase Bus systems are used exclusively for Main Generator Leads where minimal external electro-magnetic fields and maximum phase to phase fault protection is required.

TECHNIBUS offers a complete line of Isolated Phase Bus systems for those situations calling for high currents with maximum integrity. TECHNIBUS can provide self-cooled ratings up to 31 kA continuous. For forced-air cooled ratings

Enclosures are also made of high conductivity aluminum. The enclosures are manufactured from rolled sheet or plate of variable diameters and wall thickness and are welded together by using the inert-gas-shielded-arc process. High strength aluminum enclosures require minimal support allowing a free choice of the fixed points. Expansion joints in the form of aluminum bellows provided at the terminations permit thermal expansion.

The conductor consist of high conductivity aluminum. Depending on the diameter required, extruded tubes or tubes rolled from plate metal are used. The tube’s shape permits exact calculation of current displacement and heat dissipation as well as the short circuit forces. Aluminum expansion elements with welded connections allow for thermal expansion of the conductor. Maintenance is not required.

Conductor

Cast resin post insulators support the conductor and are arranged in the enclosure so as to ensure the proper clearance in air between the conductor and grounded enclosure. A sliding surface provided at the post insulator head permits relative movement between enclosure and conductor in an axial direction. One insulator of each support system is equipped with an adjustable spring-type element for compensating any variance in tube diameter during mounting as well as any conductor movement caused by a short-circuit.
