250KVA Transformer
Shinenergy’s 250KVA transformer is one kind of dry-type transformer, which is used to step down the high voltage to a lower level, the main function is to protect the utility in the electrical circuit and the operating person. It could be divided into single phase transformer and three phase transformer according to different applications.
- Employ air as the cooling medium, low fire hazard
- Provide a safe working environment, protect people and electrical equipment
- Available working in 50 or 60 Hz
- CE, UL certificated
High Quality Core and Winding Material
Shinenergy’s 250KVA transformer adopts high-quality silicone steel as the core material, high-quality aluminum foil, and copper foil as the winding material. The high-quality material with a good heat dissipation feature could reduce the power loss of the whole transformer, and prevent the high temperature internal to cause the damage of the transformer or other electrical devices.
Fully Standard Production Tests
To guarantee quality, Shinenergy incorporates fully standard production tests which include resistance tests, turns ration tests, No-load loss &existing current tests, impendence and load-loss tests, applied potential tests, and temperature rise tests.
