Varnish Impregnated Ventilated Dry-type Transformers

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 220°. Its degraded to use as class H (180°C) 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.
