Oil Immersed Electrical Power Transformers

Oil-immersed power transformers are widely used in the power systems due to their ability to handle higher voltage levels than dry-type transformers. Owing to the fact that power transformers are constantly operating under harsh thermal, electrical, and mechanical stresses, they are prone to several types of faults. Faults such as windings and core mechanical deformation, partial discharge, overheating, and arcing result in deterioration to the transformer's mechanical integrity and/or degradation to the dielectric insulation system.

1. Long life cycle
2. Hign insulation level
3. Oil leak proof design
4. Excellent control for cooling
5. Reasonabkle accessories selection
6. Strong short circuit withstand ability
7. Low loss, Low noise, Free maintenance

1. Adopting the art standard three dimesion design software to produce correct and complete engineering documentation.
2. Adopting the craft of high frequency -welding and winding-Hydraulic compaction to improve short circuit ability.
3. Adopting the craft of core Hydraulic compaction to improve the strength of core for reducing the noise level.
4. Designing the transformer base on the worst short circuit conditions for avoiding short circuit issue.
5. Adopting Electric Stress field calculation program to guarentee insulation level.
6. Adopting high quality rubber gaskets in groove for leak.

1. Adopting the Quality Control Verification Card to control quality in the whole manufacturing operations.
2. Strictly selecting the transformer raw material and the suppliers of accessories in domestic and abroad.
3. All transformers get authentication of ISO9001, ISO14001, OHSAS18001 AND CE.
4. Comprehensive Training for workes and staffs to improve service quality.
