PRODUCT DESCRIPTION
The GBC-40.5 withdrawable high voltage switchgear features the 'five preventions' (preventing misoperation of the circuit breaker, preventing the insertion or removal of the trolley under load, preventing the connection of grounding wires while energized, preventing the supply of power with grounding wires connected, and preventing accidental entry into energized compartments). Its appearance and basic performance are identical to those of the original switchgear. It is suitable for use in three-phase AC 50Hz distribution systems with a rated voltage of 40.5kV, serving to receive and distribute electrical energy. This type of switchgear is an indoor protection-type assembly that does not require wall mounting.
