The complete switchgear (CS) is designed to receive and distribute three-phase alternating current electrical energy in networks with an isolated or grounded neutral.
Switchgear cabinets of any type consist of a housing, a draw-out part and a relay chamber (cabinet). The withdrawable part is a trolley that, together with the switch, can be rolled out of the chamber for inspection, adjustment or repair.
In addition to switches, voltage transformers, arresters, rolled out for inspection and revision, are also installed on trolleys.
The withdrawable part is connected to the fixed part of the camera using detachable (plug) contacts.
The busbars are mounted on small-sized support insulators.
Measuring and control devices, relay protection and signaling devices are located in the upper front part of the chamber, and measuring current transformers and cable entries are located in the rear fixed part of the chamber.
The construction company "Olvia" manufactures switchgear for one-way or two-way service. This is a reliable and versatile equipment designed for a wide range of facilities.
Switchgear cubicles are manufactured according to a questionnaire compiled for each customer individually, with a detailed study of both the main and additional equipment, taking into account the wishes of the customer.
