High And Low Voltage Insulated Porcelain Bushing

High And Low Voltage Insulated Porcelain Bushing

Transformer bushing is the outgoing device from the high and low voltage leads inside the transformer to the outside of the oil tank, with specified electrical strength and sufficient mechanical strength. The voltage level of the coil connected with the bushing determines the insulation structure of the bushing. The service current of the bushing determines the cross section of the conductive part and the structure of the connector.

Service conditions and performance：

1. Ambient temperature: Minus 45 centigrade to 45 centigrade.

2. Altitude: ordinary casing shall not exceed 1000m, and reinforced and antifouling casing shall not exceed 2500m.

3. Ordinary casing is suitable for light pollution areas, and anti pollution casing is suitable for heavy pollution areas.

4. Installation angle: the vertical or inclined angle shall not exceed 30 degrees.

High and low voltage insulation porcelain bushing is the most commonly used type of porcelain bushing. For this type of casing, our company has professional production and testing equipment.And our technical personnel will design drawings according to the customer's requirements.
