40.5KV High Voltage Load Break Switch
Indoor High Voltage Vacuum Load Breaker Switch ,Load Switch - Fuse Combinations
General
FT16-40.5,FT16-40.5R is applied in power grid with AC 50HZ,rated voltage of 35Kv.It can be applied in breaking the load current,overload current and short-circuit current.The product is the main element of HXGT16-40.5 indoor AC metal-clad switchgear and DFT16-40.5 outdoor HV cable branch box.HXGT16 is especially designed for 35KV compact substation ,secondary small scale distribution substation.It is particularly the best choice of wind turbine generator system and power transmission gri equipment for control and protection of the transformer terminal.DTW is a transit station for power transmission cable ,used for outdoor cable line control ,contact,tap,branch or conversion.
