Chambers prefabricated unilateral maintenance series 220
Chambers prefabricated unilateral maintenance series 220
Chambers prefabricated unilateral maintenance series 220 are modular unilateral solutions.
Area of application – closed distribution substations.
Purpose – reception, distribution of electricity of 3-phase alternating current with a frequency of 50 Hz.
Rated voltage – 6-10 kV.
Operation in networks with a neutral is allowed:
– isolated;
– grounded with the use of an arcing reactor.
Chambers are made both with a retractable element and with a stationary one. If desired, the client can order a model in a non-standard version.
