Product Overview
     FZW□-27.5/D1250-20 outdoor high-voltage AC vacuum load switch-disconnector combination electrical appliance (hereinafter referred to as the combination electrical appliance), single- phase column structure, novel structure, obvious visible fracture, using operating mechanism to drive vacuum arc extinguishing , It has the characteristics of large breaking capacity, no arc when breaking and closing current, no fire and explosion hazard, quick and frequent operation, long electrical life, maintenance-free and other characteristics.

     Combination appliances are single-phase AC 50Hz, rated voltage 27.5kV, single-pole outdoor high-voltage switchgear (2000 meters above sea level), widely used in electrified railways, used for breaking load current, no-load transformer, shrinking current, capacitive current and Close short-circuit fault current.

Working Environment

1. The ambient air temperature for outdoor installation is ±40℃ ;
2. Relative humidity: not more than 95%;
3.The altitude does not exceed 2000 meters

Main Technical Parameters

   The load disconnecting switch is installed on an outdoor column. It must be able to break and close the normal load current of the line, and be able to integrate the function of an disconnecting switch to form an obvious visible fracture.The load disconnecting switch can be installed in the locomotive depot, partition pavilion, turn-back section , station yard and other section power supply places, instead of installing the disconnecting switch on the pole, eliminating the special circuit breaker used to cut off the normal load current.
