Product Description
The “GWDCD-24” outdoor high-voltage switch equipment is single-phase AC at 50 Hz. The product is suitable for power systems with a rated voltage of 10kV to make or break power supply under circumstances of voltage and no load. The isolator adopts an isolated hook rod to operate.
- The altitude does not exceed 1000m.
- The ambient air temperature: maximum: +40 °C; minimum: -30 °C; paramos: -40 °C.
- The wind pressure does not exceed 700 Pa (corresponding to 34m/s wind speed).
- The earthquake intensity does not exceed 8 degrees.
- The working situation hasn’t frequent violent vibrations.
- The installation site of an ordinary type isolator should be kept away from gas, smoke, chemical deposition, salt-spray fog, dust, and other explosive and corrosive matters that affect seriously the insulation and conduction capability of the isolator.
- Pollution-proof type isolator is applied to severe filthy conduction areas; however, it shouldn’t be any explosive matters or matters causing the fire.

Installation instructions
1 The limit mode of this model is 160° by factory default. If no limit is needed, just take out the pin in Figure 1 from the knife contact group.
2. If the limit method requires a 90° limit, the pin needs to be taken out and then installed in the position shown in Figure 2.
3. single cross-arm installation
4. double cross-arm installation
