Indoor Earthing Switch

Juhui Power Equipment Co., Ltd. manufactures indoor high-voltage earthing switches and safety protection devices for service work. Our factory is located in Yueqing, Zhejiang, covers 1,500 square meters, and has a dedicated research team. The Indoor Earthing Switch is model JN15-12. Its performance complies with GB1985-2004 AC High Voltage Disconnectors and Earthing Switches and IEC129 standards. It is at an advanced level in China. The switch is used in 12kV and below, AC 50Hz power systems and can be matched with various types of high-voltage switchgear. It provides safety grounding when workers carry out service work on high-voltage equipment. Customers can provide drawings or samples, and we can manufacture according to their designs. The MOQ is 1 unit or 1 set, and different models can be mixed in one order.

The Indoor Earthing Switch is suitable for the specified operating conditions. The ambient temperature ranges from -40°C to +30°C, while the lower limit can reach -45°C for special requirements. Applicable altitude options include 1,000m, 2,000m, and 3,000m. The wind pressure is no more than 700Pa, corresponding to a wind speed of 34m/s. The pollution grade is no higher than Class IV, and the installation site should be free from frequent strong vibration. The applicable seismic intensity is no more than 8 degrees. Its technical data includes a rated current of 24kA. The rated short-time withstand current is 31.5kA, the rated short-circuit making current is 80kA, and the rated peak withstand current is 80kA. The rated short-circuit duration is 4s, and the mechanical life is 2,000 operations. The rated current value of 24kA is retained from the original technical data and should be confirmed before final publication. The switch is used for safety grounding when workers carry out service work on high-voltage equipment. It can also be matched with various types of high-voltage switchgear and is suitable for 12kV and below, AC 50Hz power systems.

The Indoor Earthing Switch is mainly used for grounding during service work. Reliable operation of the earthing switch is important during maintenance. During installation, customers should confirm the grounding position, operating mechanism, and interlock arrangement. The switch can be matched with various types of high-voltage switchgear. Third-party inspection is accepted, and 100% inspection is carried out before packing. The warranty period is one year. Lead time depends on the order volume.
