High Voltage Ring Network Cabinet

Kexun is the manufacturer specializing in High Voltage Ring Network Cabinet in China.
Its best-selling products KXSGN-12-SIS3 is a solid insulation fully enclosed switchgear. It adopts modular, fully sealed, fully insulated and fully metal closed structure.The surface is coated with conductive or semi-conductive shielding layer, which can be directly and reliably grounded.
Model:KXSGN-12-SIS3
Brand:KEXR

● Design feature

▶ The vacuum interrupter circuit breaker and load switch module are encapsulated by epoxy resin. Modular integrated main circuit with manual and electric three-station disconnector.

▶ The vacuum interrupter circuit breaker module has the ability to open and close short-circuit current.

▶ There is a visible fracture in the closing grounding position of the three-station disconnector, and the disconnector and the grounding switch can quickly open and close the short-circuit current.

▶ The epoxy resin insulated air chamber box sealed by three-station isolating switch can pressurize dry air by 0.04Mpa. It is equipped with a pressure gauge to monitor the internal pressure online to prevent leakage and extravasation, and to protect the isolating switch and grounding switch.
