ChinaKey features
Adopting a double-sided diamond grid epoxy coating structure, a stable insulating layer is formed after thermal curing with excellent insulation performance.
It features excellent mechanical strength and dielectric properties, suitable for inter-layer and inter-turn insulation of transformer coils.
The epoxy resin contains a latent curing system, which forms a stable structure after thermal curing and can effectively reduce the risks of partial discharge and corona.
