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.
1.It is monopole and all-insulation voltage transformer, which the primary winding has only one grade, all primary and secondary winding are surrounded on Sun in Chinese character structure iron core's columns. The insulation consists of high voltage cable paper, telephone paper and cardboard etc., it will be immersed in transformer oil after desiccating under vacuum. It has advantages of stable and reliable performance for insulation, rich operated experience, long service life and convenient maintenance.
2. Perfect fluidity performance of transformer oil is good for heat dissipation, it also has self restoring capacity for the failure of partial discharge caused by air bubble and dust.
3. It can be provided two secondary measuring winding according to user's request.
4. Hermetically sealed stainless steel metallic bellows is installed on the top, whichcan protect the transformer oil and insulation paper from moisture and extend the life time, also there is a oil level gauge on the bellows for observing change of oil volume.
5. There is a multi function oil drain valve on the base, which makes it more convenient for oil sampling, draining and refilling.
6. All adopted insulation parts are environmental protection materials.
7. Secondary terminal board is made of epoxy casting, the seal performance is more reliable.
8. The base uses spray painting or hot galvanizing, which gives a high degree ofcorrosion resistance.
9. Fastcncrs and namcplate are stainlcss steel.
