Product Description

 

FLN36-12 10kv 11kv 12KV SF6 Load Break Switch in High Voltage RMU Switchgear Accessories

 

Company: Yueqing Liyond Electric Co., Ltd.

 

Summary:

 

The FLN36/48-12D/T630-25 indoor AC high voltage SF6 load switch and FLRN36/48-12D/T1250-31.5 indoor AC high voltage SF6 load switch fuse combination apparatus are designed for protecting the line of 10kV Electric Power Load Control System. They are suitable for three-phase 50Hz ring network or terminal power supply and industrial electrical equipment.

 

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

 

This product is especially suitable for urban residential areas, small substations, opening and closing stations, industrial and mining enterprises, shopping malls, airports, subways, hospitals, stadiums, etc.

 

Ambient Condition:

 

1. Altitude: ≤2000m


2. Ambient Temperature: -40°C to +40°C


3. Earthquake Intensity: ≤8 degree


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