Descriptions
XELS-12 SF6 common enclosure gas inflatable cabinet adopts modular design with its fixed and flexible expansion, to meet the requirements of users or network nodes, at the same time to meet the needs of various distribution switching stations, box-type substation, cable distribution box, with compact structure, safe and reliable, long life, maintenance-free characteristics.
Model Description
Working condition
- Altitude: ≤2500m.
- Environmental temperature: -35°~ +45°, maximum daily average temperature difference ≤25°C
- The average daily relative humidity should not exceed 95%, and the average monthly relative humidity should not exceed 90%
- Earthquake resistance: magnitude 8
Product structure Characteristics
XELS-12 SF6 common enclosure gas inflatable cabinet uses SF6 gas as insulation and breaking medium, SF6 gas is non-toxic, tasteless, non-combustible, non-explosive, with excellent arc extinguishing performance and insulation performance.SF6 gas has strong electronegativity, high dielectric strength, insulation strength is 2-3 times of air, fast insulation strength recovery, arc suppression ability is 100 times of air. XELS-12 series inflatable cabinet internal structure is compact, small volume, space saving. The gas pressure in the gas tank is 1. bar, the gas tank pressure is low, the arc suppression ability is strong.
