Our specialists in cooperation with specialists of VNIIZhT (All Russian Scientific-Research Institute of Railway Transport) have developed and manufacture section insulators operated at voltages of 25 kV AC and 3 kV DC while ensuring the passing of the current collectors of electric motive power units at speeds of up to 200 km/h.

Such insulators are installed both at stations and on the lines replacing the multi- section air gaps in particular, they are used to make neutral inserts of the catenary.

With regard to their electric and dynamic performance, reliability and especially as regards their efficiency of arc extinction and according to their low prices, they notably surpass the section insulators produced by such companies like BICC, REBOSIO, LERK and others.

Our insulators are sold well both in home and foreign markets. For example, our section insulators are installed on a high-speed rail line in South Korea and got full marks of Korea National Railroads.

Except of selling of the insulators we lend any consulting and technical services for assembling, mounting and installation on the concrete catenary system.

In case of your interest, we are ready to consider any suggestions of co-operation on the base of mutual benefit and to answer any questions.

The basic characteristics of section insulators of our manufacture:

Maximum permissible speed of electric motive units 200 km/hour
Operating standardized tension of contact wires 10-20 kN
Testing mechanical tension load of insulating element (runner) > 50 kN
Mechanical strength of the connection of the insulating element (runner) with contact wires > 30 kN
Average service life 20 years
Average resource, number of passing current collectors 5 х 105

Section insulators for the catenary system of urban surface electric transport


Three years ago our company has developed and started successfully to use several types of polymeric insulators: suspending, bracket-type, strain and universal (suspending-strain). These insulators meet all up-to-date requirements of operation.

All manufacturing types of insulators have passed through bench and service tests under conditions of Russian railroads and certified in accordance with Russian standards. Under the customer’s request we can produce products met all requirements and operating conditions.

Except of selling of the insulators we lend any consulting and technical services for assembling, mounting and installation on the concrete catenary system.

In case of your interest, we are ready to consider any suggestions of co-operation on the base of mutual benefit and to answer any questions.
