Fully Sealed and Fully Insulated Gas-filled Ring-network Cabinet

Product overview

Full-sealed and fully insulated gas-filled ring-network cabinet (hereinafter referred to as "gas-filled cabinet") is a new generation of high-voltage switchgear, which has all the functions of 10KV high-voltage switchgear. It has the characteristics of small floor area, high degree of intelligence, maintenance-free, full-working condition, compact structure, flexible operation, reliable interlocking, etc., and is suitable for various applications (especially in places with harsh environment).

Normal service conditions

Ambient temperature: - 25 ℃ -+50 ℃

Altitude:<4000m (more than 4000m, please specify when ordering)

Relative humidity: ≤ 95% (25 ℃)
Seismic intensity: ≤ 8 degrees
Installation environment: no fire, explosion hazard, serious pollution, chemical corrosion and violent vibration.

Applicable place

Inflatable cabinet is suitable for small secondary substations, switching stations, box-type substations, residential quarters, industrial and mining enterprises, and large shopping malls of the power system, especially for airports, subways, railways and other places with high power requirements.

Product features
1. Cabinet structure features: The inflatable compartment is generally made of 3mm thick stainless steel plate with strong corrosion resistance and welded by welding robot. It is characterized by less welding deformation, good air tightness and good strength.
2. Strong applicability: the cabinet is not affected by atmospheric conditions, and has little impact on high altitude, condensation, salt fog, pollution and other harsh environments. The cabinet shell is small in size, saves floor space, and is more compatible with the surrounding environment in terms of layout, size and appearance, making the comprehensive economic benefits of the project construction very obvious.
3. Good safety performance: the conductive part of the main circuit of the gas-filled cabinet is sealed in SF6 and other insulating gases, so that the high-voltage live conductor is completely closed, with the advantages of high reliability and suitable for frequent operation.
4. High maintenance performance: Because various high-voltage components of the gas-filled cabinet are insulated with SF6 gas and sealed with metal, the parts are free of corrosion and rust, and there is no operation and electrical conductivity impact caused by it, so the maintenance workload is very small. The vacuum circuit breaker used has long service life and stable performance, and can also be maintenance-free or less maintenance.
