Description


The medium voltage switchgear type R40 is manufactured for use in electrical installations with an operating voltage of up to 35 kV and a current of up to 1600A.

Equipment is intended for use in switchgears of enterprises producing, transmitting and consuming electrical energy.

The switchgear cell is divided into 4 main compartments: auxiliary circuits compartment (low voltage circuits), switch compartment (main circuits), connection compartment (main circuits), busbar compartment.

The switchgear is a metal structure with an IP4X degree of protection, with air insulation, with a single busbar system. The switchgear is made in two versions: one-way and two-way maintenance, depending on the requirements of the project.
