introduction of 35kV double-winding power transformer
GNEE TRANSFORMER supplies 35kV oil-immersed three-phase double-winding on-load voltage regulating power transformer.
35kV series transformers are with the following characteristics: low loss, low noise, protection against thunder and lightning, high short-circuit withstand capacity and beautiful appearance etc. It is made by advanced assembling lines and method, with qualified and refined accessories. It enjoys four remote functions: "remote communication remote test, remote adjustment and remote control" . By remote control from a computer, the power station could be free from supervision in the office. 35kV series energy saving transformers have passed the identification Test by State Bureau of Machinery Industry, and State Power Corporation.
35kV series transformers are mainly used in urban and rural power grids and other industrial, mining enterprises, power transmission and distribution industry and also agriculture projects.
features
- Good economic performance: The no-load current drops by 60%~80% on average, The no-load loss is reduced by 25%~35% on average.
- Long lasting: The transformer oil tank adopts a fully sealed structure. The oil tank and the tank edge can be connected by bolts or welding. The pressure oil does not come into contact with the air, extending the service life.
- High operational reliability: The relevant parts of the fuel tank seal have been improved to increase reliability and improve the process level to ensure. Prove the reliability of the seal.
- Small footprint: The transformer oil tank adopts a corrugated plate radiator:When the oil temperature changes,the corrugated plate thermal expansion and contraction can replace the role of the oil conservator. The corrugated plate oil tank has a beautiful appearance and a small footprint.
