Overview
Transformer bushing is an outlet device for the high and low voltage leads inside the transformer to the outside of the fuel tank. It has specified electrical strength and adequate mechanical strength. The operating current of the casing determines the cross section of the conducting part and the structure of the connector.
casing is mainly made of brass, porcelain bottles and epoxy resin. These materials have excellent electrical properties and mechanical strength. It can withstand harsh natural environments and chemical corrosion. The built-in high quality porcelain sleeve provides additional insulation protection to ensure safe and reliable current transmission. Ceramic bushing is widely used in power transformers, distribution transformers and various high-voltage electrical equipment, transformer bushing is the ideal choice for connecting cables and transformers. It can effectively prevent the leakage of transformer oil, while resisting the invasion of the external environment, such as moisture, dust and other corrosive substances.
Conditions of use
*Ambient temperature: -45 degrees to +40 degrees.
*Altitude: ordinary type casing does not exceed 1000 meters, enhanced and anti-pollution type casing does not exceed 2500 meters.
*Transformer bushing is suitable for light pollution areas, anti-pollution type casing is suitable for heavy pollution areas.
*Installation Angle: vertical or inclined Angle does not exceed 30 degrees.
