TERMINAL LEAD-OUTS OF GENERATORS

        

We manufacture the terminal lead-outs using fibre-glass plastic insulators for turbo-generators with air, hydrogen and water cooling of the stator windings with capacity up to 500 MW and voltage not more than 20 KV.

The material used for manufacture of cylinders meets the requirements of specifications TU U 26.1-22641550-001-2004.

The design is developed and 4 sets of the terminal lead-outs for 100 and 200 MW turbo-generators are manufactured
for «KONCAR-Generators & Motors Inc.», Croatia.
Currently there is the active co-operation with the customers in Ukraine.

 

The terminal lead-outs are manufactured and supplied to:

-Burshtynskaya Thermal Power Plant

-Zuevskaya Thermal Power Plant

-Uglegorskaya Thermal Power Plant

-Starobeshevskaya Thermal Power Plant

-Luganskaya Thermal Power Plant

-Kyivskaya Hydro Power Plant

We are able to develop the design of lead-outs for other types of machines in compliance with the Customer’s
Statement of Work.
