1. Excellent insulation performance
The SF6 High Voltage Load Break Switch 12kV 36kV has outstanding insulation performance, which can effectively isolate the electric field between conductors and grounding bodies, ensuring the normal operation and electrical safety of power equipment. Especially in recent years, with the increase in voltage levels, the demand for high-performance insulators has been increasing, and the application scope of insulators has also become more extensive.
2. Long service life
The insulating materials are usually high-strength ceramic materials, silicone rubber materials, glass fiber reinforced plastics, etc. Their service life is much longer than that of traditional metal materials, and they can maintain excellent insulation performance for a long time.
3. Good heat resistance
The insulator can adapt to high-temperature environments, maintain excellent insulation performance, and can withstand high pressure, electric field and strong current intrusion. Therefore, it is widely used in high-voltage power equipment.
4. High cost recovery rate
Although the price of this insulator is higher, its service life is also longer, and it does not require maintenance during use. Therefore, its cost recovery rate is high, and it can reduce the user's usage cost.
