1. The shell is made of high-quality stainless steel or ordinary steel plate, which is sprayed with UV resistant varnish after Dacromet antirust treatment process. The product has excellent anti friction, anti salt fog and other anti environmental properties. 2. APG fixed insulated pole is encapsulated with silicone rubber (as insulation and buffer), with small volume, excellent anti condensation performance, long working life and reliable performance. 3. The operating mechanism is a spring operating mechanism, which can be manual or electric. When necessary, a remote control operating device and a device to avoid closing inrush current can be added. The required power of external power supply is no more than 70W, which is easy to be equipped with backup power supply. The buffer device with unique design has excellent performance, small rebound and low noise. 4. The arc extinguishing chamber adopts special stainless steel brazing technology without electroplating, with high welding quality, stability and reliability and low air leakage rate. Special ceramic metallization formula and advanced ceramic metallization process are used in the manufacturing process to ensure the air tightness of the product, and the tensile strength is 130Mpa Complete primary sealing. 5. The current transformer is made of high-quality magnetic conducting material and composite insulation of epoxy resin and silicone rubber. It has the advantages of large capacity, high dynamic thermal stability, high precision level, maintenance free and high reliability.
1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h. 2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M. 3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually. 4. Installation gradient not exceed 5. 5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components. 6. Any specific requirement, consult with manufactory.
