Vacuum load switch:FT6 (FZW3A)-12/T630-16 Outdoor AC HV Vacuum load switchgear [Clicked:248] 
FT6 (FZW3A)-12/T630-16 Outdoor AC HV Vacuum load switchgear
General :
FT6 (FZW )-12/T630-16 Outdoor AC HV Vacuum load switchgear£¨hereinafter referred to as load switchgear£© can be used in outdoor three-phase AC power system of rated voltage 10KV and rated frequency 50HZ for opening and closing load current, non-load line and non-load transformer.

Features :
Vertical rotating structure is used for this kind of product, which can avoid the risk of closing automatically.
Vacuum arc-extinguished compartment is equipped in the fully sealed enclosure that operated by high-speed mechanism, and will be not influenced by the outside operation and environment. It can do arc extinguish safety and reliably.
The safety of operation is improved by the connection of vacuum arc-chute and isolating control with no possibility of mis-operation. It has obvious fracture that meets the requirements of disconnecting protection.
The material of the exposed components is made of stainless steel, and has long life service.
The characteristics of the switchgear are neat structure, small volume, less weight and simple, reliable mechanism. It can be operated by two methods: manual operation or dual-purpose operation that is manual or electric. It can be used in the automation of network or the operation of sectional device.The weight of load switchgear: manual or electric operation <=65kg, manual operation<=55kg.
