General

The VCB unit in the entire group of equipment is also called a vacuum V-type unit, which is used to break short-circuit current, and its circuit breaker is connected in series with a two-position isolating switch.

When the isolating switch is in the off position, the interlock grounding switch will close to ground the cable bushing.

The operating mechanism between it and the isolating switch and the operating mechanism between the isolating switch and the grounding switch are mechanical.

Service environment

Air temperature: -35℃~+40℃
Humidity: Monthly average 95%; Daily average 90%.
Altitude:≤ 1000m (Up to 5000 m can be custom)
Ambient air is not apparently polluted by corrosive and flammable gas, vapor, etc.
No frequent violent shake
