- In line with the requirements of reducing exhaust gas pollution of electrical products advocated by the state, it is suitable for small secondary distribution stations, switching stations, industrial and mining enterprises, airports, railways, business districts, high-rise buildings, highways, subways, tunnels and other fields. Especially in plateau, humid, cold and low-lying special environment.
Product advantage
> Leading technology
- cancel the greenhouse gas SF6, and all materials are non-toxic and harmless environmental protection materials.
- compact structure, small occupied space, safe and reliable.
- the product is designed in a modular way, and each functional unit can be combined freely, which is flexible and convenient,
- the outer surface of solid insulation is covered with grounding layer. It avoids the accident of human body touching by mistake, and even avoids the fault of phase to phase short circuit;
- visual fracture technology is adopted, which greatly improves the safety of operation;
- the fixed pole, bus and melting drum are fully insulated and touchable;
- it is resistant to harsh environment. Unlike SF6 switch, the air pressure gradually decreases at low temperature, and the insulation decreases, affecting the insulation performance.
> Busbar system
- Adopt three-phase four-wire system or three-phase five-wire system
- High quality three-phase tin bus copper bar, high mechanical strength, good heat dissipation
- The flat bus arrangement makes the device have good dynamic and thermal stability, and can withstand 80/176kA short circuit current impact
> Processing and assembly
- Dust-free workshop to ensure insulation
- Assembly workers have been trained for at least 6 months
- The secondary connection is automatic terminal crimping machine to ensure reliable connection
- Use power tools to ensure proper torque for bolting reinforcement
- The copper bus is CNC cutting, punching and bending to ensure the accuracy
- All kinds of experimental tests before delivery to ensure the normal operation of the equipment
Conditions of use
- Altitude shall not exceed 2000m
- ambient air temperature not higher than +40 ° C, not lower than -5 ° C (average temperature within 24 hours not higher than +35 ° C)
- The humidity of the surrounding air should not exceed 50%. Low temperature allows a large relative temperature (e.g. +20 ° C is 90%). Consideration should be given to the effect of condensation caused by temperature changes
- Inclination with vertical plane is not more than 5°, and the whole group of cabinets is relatively flat, in line with (GBJ232-2) standard
- Requested in no violent vibration and impact, electrical components will not be corroded, no conductive dust place
