Product overview
This product adopts SF6 insulation gas high-performance sulfur hexafluoride load switch and touch shield imported synthetic rubber cable connector, with strong active load and no-load cable current breaking capacity and short-circuit current closing capacity, and can be equipped with lightning arrester and ground fault indicator according to user requirements. Each ring network line in this series is equipped with a load switch or vacuum circuit breaker. Any branch circuit can be freely withdrawn and put into operation. Other ring network circuits are not affected. A fuse can also be attached to the load switch. When a short-circuit fault occurs in a branch circuit, the fuse on the branch circuit can quickly disconnect the fault circuit and impact the tripping device of the load switch to separate the fault circuit, thus ensuring the continuity of the power supply of the non-fault branch circuit.
This product is widely used in 10kV power system cable tap. The connection method is simple, flexible and convenient, safe and reliable, and the cabinet body is made of stainless steel plate, which is sturdy and durable. The live part is fully insulated and fully sealed. Such as the use of flood control can touch type cable head, but also can resist flood attack, greatly improve the reliability of power supply. The product is widely used in urban industrial district, residential district, high industry center, mining area airport, railway, wind power station, iron and steel, petrochemical, cement and other large enterprises and other occasions of the distribution network, especially suitable for urban road power grid reconstruction project, can greatly save electrical equipment and cable investment, improve the reliability of power supply.
