Product Description

The transformer bushing is an insulating bushing that leads the high and low voltage conductor inside the transformer to the outside of the oil tank.
It's not only used as an insulation from the conductor to the ground, but also assume the role of fixed lead.
Transformer bushing is one of the current carrying components of transformer, in the operation of transformer, it passes through the load current of a long time, and the short-circuit current when the external short circuit of the transformer occurs.
Therefore, there are the following requirements for transformer bushing:
1. Must have specified electrical strength and sufficient mechnical strength.
2. It is necessary to have good thermal stability and can withstand the instantaneous overheating in the short circuit.
3. Small shape, light in weight, good sealing performance, strong versatility and easy maintenance.

Service Environment

1. Ambient temperature: -35ºC~+55ºC;
2. The common type is suitable for the area of light pollution, and the antifouling type is for the area of heavy pollution;
3. Installation method: vertical or horizontal installation.
