Описание

High current capacitive wall bushing is greater than 2000A and can reach up to 6300A. It is suitable for three-phase AC system power stations and substation distribution devices. It allows the conductor to pass through walls or other grounding objects and serves as an insulation support and fixed connection between external wires.

Features

no-porcelain, no-gas, no oil
Fireproof, explosion-proof
Maintenance-free
Smaller volume, lighter weight
Ambient air temperature from -40 ℃ to +50℃

12-40.5kV Heavy current transformer drawing.
