China Transpowers Electric Co., Limited
Features of the products:
Compact size and light weight:
The relative medium constant of NOMEX paper is 2 which is very close to the air. So, the adopting of NOMEX paper can avoid electric field concentrated, decrease the partial discharge.
Strong overload capability:
NOMEX paper belongs to class C insulation material whose heatproof temperature is 220C. Its degraded to use as class H (180C) material will ensure the over-load capability of the transformer.Safe and environmental-friendly:
Flame-proof, explosion-proof, and no pollution.
Can be recycled conveniently when transformer life ending after 30 years'use.
Power capacity: 30~4000kVA
