Product Description

Main Function And Features 

110kV oil-immersed OLTC Power Transformer grounding transformer
1Power transformer 220kv 110kv and 66kv low-loss series
2low loss, low noise, high reliability
3Iron core is made of cold-rolled silicon-steel
4Have good ability withstand short-circuit
5The oil tank is bell type with the structure of full folding plate type,
6Having an excellent exterior and easy for maintenance
7Adopting capsule-type oil container, it can reduce oil aging to the lowest degree
8Power loss: no-load loss is 30% lower than that of IEC standard
9Reliability: All in-service product have no damages or oil leakage occurred


Core1Power transformer  core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet
2The material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm.
3Power transformer  silicon sheet fabrication adopts “no-upper yoke-lapped’ technology and all lapped joints of the silicon sheet are 45 full-miters
4Effectively improves no-load performance and reduces noises.

Coil1The high-voltage(HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed.
2All stays and pads are chamfered to keep highly reliable insulation.
Oil tank and accessories1Power transformer tank wall adopts wide steel sheet
2Which will be folded into corrugated structure without splicing
3In this way welds aredecreased and mechanical strength is enhanced
4The corrugated wall has diverging effect, and thus plays arole in decrease of noise.
