Chambers prefabricated unilateral maintenance series 219
Chambers prefabricated unilateral maintenance series 219
Prefabricated unilateral chambers series 219 are used in indoor distribution substations. Designed for the reception and distribution of electrical energy of alternating three-phase current with a frequency of 50 Hz, voltage of 6 (10) kV in grids with isolated or grounded neutral.
In the case of a two-row installation, the chambers prefabricated unilateral maintenance Chambers prefabricated unilateral maintenance series 219 are equipped with busbar bridges with and without disconnectors.
The disconnector drives of busbar bridges are installed on the end panel.
