Service assembled chamber of unilateral maintenance

Service assembled chamber of unilateral maintenance is designed for completing closed switchgears with a voltage of 6 or 10 kV AC with a frequency of 50 Hz for systems with an isolated neutral. They are installed in closed electrical panel rooms of industrial enterprises and power supply facilities.

Service assembled chamber has one-way maintenance with single-row or double-row camera arrangement. The design of service assembled chamber of unilateral maintenance cameras provides for the Assembly of cameras into a switchgear from different chambers in value and the connection of the main circuits via busbars. The switchgear is bounded on both sides by end panels. Service assembled chambers of unilateral maintenance chambers located in two rows facing each other are connected by a bus bridge.

ZENCHA-Pskov JSC is ready to consider the possibility of manufacturing any metal product, plastic products, electrical products according to the customer's design documentation.
