Yuanky GW8 and GW13 series neutral‑point disconnecting switches contain multiple specifications covering 40.5kV,72.5kV and 126kV, the rated current of all models is 630A, they have good capability of short‑time withstand current and lightning impulse withstand voltage, and the mechanical life can reach 2000 times. GW8 series can be fitted with CS8‑5 manual mechanism or CJ6 horizontal electric mechanism, while GW13 series supports CS17‑G manual mechanism or CJ2‑G electric mechanism. GW13 also has indicators of minimum insulation gap after opening and main circuit resistance, these products have different single-pole weight and leakage distance grades to meet various outdoor power grid neutral point isolation demands.
