SF6 gas potential transformer

This product is single phase SF6 gas insulation potential transformer. It is for 110kV, 50Hz or 60Hz electricity system, for current and electric energy measurement, and relay protection etc.

This product is single stage type insualtion structure. The primary winding not to be classification, it suit on the core column of the iron core with the secondary winding. The insulation is mainly made by plaid film which be placed in the tank with SF6 gas, the insulation performance is stable.

This product adopt SF6 gas and plain film as the main insulation materials, the insulation performance is stable, and there is no insulation ageing problem. The service life is long and partial discharge value is small.

Maintenance easy: Judge the operation is good or not by observing the density controller value when normal patrolling. The gas leakage rate per year is less than 1%, this product can be without maintenance for ten years.
