Product Description

SF6 RMU Load Break Switch without Mechanism for Switchgear

Introducing FLN36-12D/T630-25 indoor AC high voltage SF6 load switch and FLRN36-12D/T1250-31.5 indoor AC high voltage SF6 load switch fuse combination apparatus from Yueqing Liyond Electric Co., Ltd. These products are designed for three-phase 50Hz ring networks or terminal power supplies, providing protection for 10kV Electric Power Load Control Systems.

The load switch can handle load current, closed loop current, no-load transformer, and cable charging current. The combined apparatus can break any current up to the rated short circuit level, making it suitable for ring network units, box-type substations, and more.

These products are ideal for urban residential areas, small substations, opening and closing stations, industrial and mining enterprises, large shopping malls, airports, subways, hospitals, stadiums, and other locations.

Ambient Conditions:

• Altitude: ≤2000m


• Ambient Temperature: -40°C to +40°C


• Earthquake Intensity: ≤8 degree


• Relative Humidity: Daily averages ≤95%, Monthly average ≤90%
