RW11、RW12 OUTDOOR HIGH-VOLTAGE DROP FUSE
Product Overview
RW, HRW, HPRW series outdoor high-voltage drop-out fuses (hereinafter referred to as "fuse") are used in the power system of AC 50Hz, voltage 12kV, 35kV, application for short-circuit and overload protection of power lines and power equipment, and open and close current.
Working Environment
1. Ambient air temperature: upper limit +40℃ , lower limit -30℃ ;
2. Altitude: ≤ 1000m;
3. Relative humidity: daily average value is not more than 95%, monthly average value is not more than 90%;
4. No frequent severe vibration;
5. Pollution level: Grade III;
6. There is no place with fire, explosion hazard and chemical corrosion.
Product Mix
The fuse is mainly composed of an insulating support and a fuse tube. The static contacts are installed at both ends of the insulation support, and the dynamic contacts are installed at both ends of the fuse tube. The fuse tube consists of an inner arc suppression tube and an outer phenolic tube. Composed of paper or epoxy glass cloth tube.
