Product Description

ZIKAI® is one of the famous China Air Insulated Switchgear manufacturer and supplier. Our factory specializes in manufacturing of Air Insulated Switchgear. Every request from customers is being replied within 24 hours. AIS mainly relies on air as its insulating medium. Under standard atmospheric conditions, that is, under a certain temperature, pressure and humidity, the air has sufficient insulation strength to prevent current leakage and short circuit between electrical equipment. AIS devices are usually composed of multiple independent switching components, including but not limited to circuit breakers, isolation switches, current transformers, voltage transformers, etc. These elements are isolated by air gaps and use air as an insulating medium between them.
