Toughened glass insulator which is applied to insulate and suspend cable wire used in high and ultra-high voltage. It is to increase the creepage distance.
It is consiting of cap and pin with concrete cement. We adopt the most advanced international cylinder head. It's feature is little and light head which can save matal meterial ans reduce the cost of wiring. It is not easy to aging and have self-cleaning function.
