Introduction

Veneta Isolatoriis a leader company specialised in the production of MV epoxy resin insulators for electrical and

electromechanical industry. The company was established in 1974, in 1990 it became a subsidiary

of COMEM S.p.A, leader in oil transformer component and solution. In 2009 all the activities were

moved to a new factory located in Ceggia close to Venice.

The long experience achieved by Veneta Isolatori gave the possibility to develop a wide range of

products, having suitable and tested electrical and mechanical technical characteristics. Recently

the company has also developed insulators in silicon rubber for outdoor installation. Nowadays

Veneta Isolatori represents a reference point for many of electrical companies, that use Veneta

Isolatori partnership for the development and realisation of insulators according to their own

basic design. The export, almost 50% of the total production, cover a winde range of countries

and MV application.

Certification

The Quality System certified by an external indipendent organisation is:

UNI EN ISO 9001: 2008

The Environmental Management System and the ISO 14001 Standards for the Health and Safety

Management System according the OHSAS 18001 Standards, are considered regarding application in

production and building site activities.

Laboratories

The Unit has internal laboratories equipped with state-of-theart apparatus for carrying out tests on

materials, experimental, climatic, mechanical life, dielectric and partial discharge.

Operation

Each design parameter is known, measured and recorded for each piece of insulator produced, so

that their functional suitability can be declared in accordance with what is prescribed in the Standards.

Production is also supported by lines which operate using the fabrication system with functional blocks.

Thanks to this innovative system, the production lines can outfit each typical unit with maximum

efficiency and speed.

Type SF - SCVoltage presence indicators


The voltage presence indicators are devices used to supply information about the main

circuit status inside the equipment where the devices are installed. To each lamp placed

inside the indicator (L1 L2 L3) corresponds one phase of the input line. The line voltage

presence is indicated by switching of the relevant lamp. The signal of voltage presence

necessary to switch the lamps is sourced out by a capacitive coupling with an insulator

equipped with capacitive output.

Application

In MV cubicles for operating voltages from 1 to 36 kV.

Type SF

The indicator SF is a light signal device made of one single

fix part. The indicator is equipped with a safety system,

composed of one gas arrester for each phase, which

connects the system to ground in case of overvoltage

> 600 V. The arresters are self-resetting, this means that at

the end of the discharge the device will start again to function

normally.

Type SC

The indicator SC is a light signal device made of one fix part

and one mobile and removable part.The lamps are placed

in the mobile part. The indicator is equipped with a safety

system, composed of one gas arrester for each phase, which

connects the system to ground in case of overvoltage > 600

V. The arresters are self-resetting, this means that at the

end of the discharge the device will start again to function

normally.

Type PRB 24-36 kVAir-air bushing for indoor use


The PRB bushings can be used as medium voltage inlet for indoor air insulated devices

such as switchgears, in particular for applications in quite small machines.

The bushings are realized on the one side with a coupling interface in accordance with

EN 50180-50181 (DIN 47636; HN 52-S-61) standards. This type of interface allows a

connection with the relevant moving connector. On the other part the sheded side allows a

bare electrical wire connection.

Accessories

Plastic cap for coupling interface protection.

Only on request, alluminium flange suitable to fix the bushing to the steelwork.

The fixing flange is necessary for the 400A version for mobile connector fastening.

Assembling instructions

Bushing insulator PRB

Prepare the holes on the body of the tank as indicated in the steelwork holes Lay-out. Remove the paint, or any insulating coat

in the area of fixing holes, in order to guarantee a correct earth connection of the bushing.

Moreover, make sure that the surface where the bushing is placed is without any type of roughness or unevenness. It must be

completely clean in order to guarantee a perfect tightness. It is recommended to use the fixing flange in order to strengthen the

area where the bushing is fixed to the tank. For 400A version the use of the flange is necessary for mobile connector fastening.

Place the flange, when used, and tighten the 3 fixing screws M6, together with their relevant washers, with a tightening force

value of 9÷11 Nm. The tightening operation must be done crosswise. The lower connection (M16) must be fastened with a

tightening force value of 90÷100 Nm.

During mounting operations the plastic protective cap must be fitted and pressed right down on the bushing, in order to avoid

faults caused by dirt or accidental scratching of the interface.

Assembling instruction

PGS bushing (Fig. 1 and 2):

– Drill the holes on the body of the tank as indicated (9).

– Remove the paint, or insulating coat, in the area of the

fixing fastener holes in order to guarantee a correct earth

connection of the bushing.

– Moreover make sure that the surface where the bushing

holds is without any type of roughness, or unevenness and

it must be perfectly clean in order to guarantee a perfect

tightness of the flat gaskets.

– Place the bushing (7) on the metal structure after having

positioned the gasket (8). Place the aluminium flange

(10) inside the tank and tighten the six fixing screws (11)

together with the relevant washers with a tightening force

value of 9÷11 Nm. The tighting of the screws must be done

crosswise. The lower connection to the M10 threaded hole

must be fixed with a tightening force value of 30÷35 Nm.

Silicon rubber protection (Fig. 3 and 4):

– Remove the plastic protective cover (4) from the bushing.

The plastic protective cover must be fitted and pressed

right down on the bushing always when:

– the bushing is not connected to the movable connector;

– the bushing does not have silicon rubber protection.

This prevents faults caused by dirty or incidental scratching

of the interface (6).

– Clean with alcohol the interface (6) and the area of contact

with the silicon rubber protection (3).

– After the complete evaporation of the solvent, spread

evenly over the connection interface (6) the grease

contained in the enclosed pocket (5).

– Pull the silicon rubber protection (3) on the bushing (7)

and screw down tightly until maximum torque is obtained

(90÷100 Nm). This can be done with the aid of a 20

mm spanner used on the top cap (2). The silicon rubber

protection is correctly clamped if the bushing is totally

covered with it.

– Turn the silicon rubber protection slightly to the left and to

the right to distribuite grease evenly over the connection

interface (6).

Type BSLComposite insulators for line switches


The composite insulators type BSL are suitable to be used in MV line switches.

These insulators are realized with a fiberglass and epoxy resin core and aluminium end

fittings and covered by silicon rubber. This material gives best performances for an outdoor

use: abrasion resistance against UV rays, in environements with very high pollution level and

with high salinity concentration. Silicon is unbreakable and hidrophobic. It is not necessary

to plan any maintenance operation, even in particularly difficult environement conditions.

Application

Outdoor line switches.
