Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable transformer manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations and high and low voltage complete sets of equipment.The equipment put into production and operation of the project advocates energy saving, intelligence, information 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.
High temperature and high overload oil-immersed transformer is a kind of transformer specially designed to cope with high load and high temperature environment, has excellent performance and a wide range of applications, for the stable operation of the power system provides important support and guarantee.
1.Strong overload resistance: On the basis of rated temperature rise, it can withstand 1.5 times for 6 hours, 1.75 times for 3 hours, and 2 times for 1 hour, without affecting the service life of the transformer.
2. Excellent heat resistance: The only DuPont NomexT910 insulating paper certified by UL in the United States has a higher temperature rise limit and excellent heat resistance.
3. Reliable safety performance: The selection of high overload transformer oil, the ignition point and flash point are much higher than the ordinary transformer oil, under high temperature conditions, with higher safety performance.
4. Superior comprehensive economic operation benefits: In the use of the station area, high overload transformers have higher comprehensive economic benefits.
5. The performance level is consistent with that of ordinary transformers: The parameters of both are consistent, that is, the high overload transformer achieves high strength overload capacity without sacrificing other electrical performance.
