Main features
The fully insulated and fully enclosed (standardized) main ring unit metal switchgear adopts SF, gas as arc extinguishing andinsulating medium.
The switchgear is fully enclosed and fuly insulated: the bus, switches and live parts are completely enclosed in its stainless steelshell. The cavity is filled with sF,gas at 0.04Mpa, and its ingress protection is lP67, The whole switchgear is not influenced by externaenvironmental conditions, even in special conditions such as short+-time waterimmersion,its normal operation is guaranteed and itis free from maintenance for its whole life.
The switchgear is equipped with a perfect five-protection interlocking to prevent any personnel injury or fault due to any error inoperation, All switchgears are equipped with reliable pressure relief channels to guarantee operators' personal safety in specialconditions.
The switchgears are divided into two types: non-expandable combination and expandable combination, with cabling from thefront or cabling from the side or expanded from the side according to various installation positions, The cabinet is easy to installis ideal for a small space or an area with unfavorable environmental conditions, The switchgear can be equipped with electricactuator, remote control and monitoring device accordingto various users’needs.
With great feeder capacity and a small area occupied for various applications.
