GW5 ( GT10 ) - 126D 126kv Outdoor HV Disconnector / 110 kv Disconnecting Switch
GW5 (GT10)-126D/1600-40 Type Outdoor AC HV Disconnector is developed on the basis of aiming at the GW5-126 type disconnector existing defect about earthing flashover, large operating force, contact leaves contact area when bevel gear tooth broken or closing position out of control and under the action of wind, through investigation and analysis. It is the update product our company recommends to HV power distribution network.
It is suitable for system with 50Hz AC frequency and 110kV rated voltage. It can be used in changing-over when HV circuit is no-load and electricity isolate maintained HV busbar, circuit breaker and other electrical equipments and alive HV wire, as well as used for breaking small capacitance current or inductive current.
a. Reasonable principle, simple design.
b. Strong anti-electrodynamic force, the short-circuit current can reach 40kV/3s.
c. Horizontal single fracture. Obvious and reliable insulating isolating distance can be formed under opening status, which is convenient to maintain and operation. Interlock is reliable.
d. Beautiful appearance and covers little area.
