WSSRM-12 fully enclosed fully insulated inflatable ring network switchgear
WSSRM mouth-12 fully enclosed fully insulated gas-filled ring network switchgear is a completely sealed system, and its live parts and switches are enclosed in a stainless steel body. The entire switchgear is not affected by external environmental conditions, thus ensuring operational reliability and personal safety. And it is maintenance-free. ···
Model and Its Meaning
Examples:
1.WSSRM-12-C/630DL indicates a load switch cabinet with a rated voltage of 12kV, a rated current of 630A, right side expandable, and left cable entry/exit method.
2.WSSRM-12-CF/6301R indicates a combination of a load switch unit and a fuse unit, with a busbar voltage of 12kV, a busbar current of 630A, left side expandable, and right cable entry/exit method.
Normal Operating Environmental Conditions
Ambient air temperature should not exceed +40ºC and should not be lower than -5ºC, with the average temperature over 24 hours not exceeding +35ºC. Indoor installation and use, with the installation location's altitude not exceeding 2000 meters.
Relative humidity of the surrounding air should not exceed 50% at a maximum temperature of +40ºC. Higher relative humidity is allowed at lower temperatures (for example, 90% at +20ºC). Consideration should be given to the possible effects of condensation due to temperature changes.
The equipment's installation should not exceed an inclination of 5° from the vertical plane.
The equipment should be installed in places without severe vibration and impact, and where electrical components are not exposed to corrosive environments.
If users have special requirements, they can negotiate with the manufacturer for solutions.
Cabinet Structure
The basic structure of the switchgear cabinet is assembled from C-shaped profiles. The C-shaped profiles are made from steel plates bent with E=25mm modular mounting holes. All cabinet frames and inner partitions are treated with galvanization and phosphating. The surrounding door panels and side panels are treated with high-voltage electrostatic powder coating.
