Product Advantages

Solid Insulation

Shielded layer of conductive material makes the surface at earth potential everywhere; it is accidently touchable providing safety features for operator. This shielded solid insulated switchgear, which is completely solid insulated, has entire circuit insulated by epoxy and silicon rubber, leaves no live parts in free air; given switchgear less affection of dirt, humidity and pollutions etc.; requires less necessity for maintenance. Each phase is selfcontained into single epoxy block, significantly reducing phase to phase discharge and risks of internal arc fault.

Modular architecture

Modular architecture enables reduction of switchgear dimensions Dimensions of Solid Insulated Switchgear : 700 × 2000 × 1150 it is only 1/6 of traditional air insulated type ie KYN61.

Optimized Electric Field

Computing technology facilitate optimal design of electric field and isolation.

Safety

Sealed electrified body IP67. Inner cone cable terminal to improve the connection reliability

Extreme Environment Application

Suitable for cold, high altitude, humidity, corrosion, lowland and explosion-proof area.

All Operating Condition Environment

Ambient temperature: -50 ℃ ~ +70 ℃ ; Altitude: ≤ 5500 m Internal and external arcing test report (switches, bus bar, cable compartment) detection Immersion detection test report Salt spray testing report The circuit breaker is composed of mechanism transmission box and circuit breaker poles.


Earthing /Disconnecting switch assembly	There are three internal cone sockets in the poles, among which the 2# cone is used for installing lightning arrester, and the two 3# cones are used for connecting 630A cables.
