Product Description
Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable power equipment manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations, high-voltage switches, and medium and low voltage complete sets of equipment. The equipment put into production and operation of the project advocates energy saving, intelligence, informatization, and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center, with 71 utility model patents and 15 invention patents. With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.
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.
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.
