In addition to its long electrical life and strong braking force, it has the same advantages as the vacuum load switch. Its outstanding advantage is that it is easy to achieve three working positions (connected, disconnection and grounding), small current (inductance, capacitance) breaking, strong resistance to severe environmental conditions. It is suitable for popularization and application in urban and rural medium voltage distribution networks. <br> <br>As an electric power equipment company, we will do our best to meet all the needs of customers. <br> <br> <br>[a]https%3A%2F%2Fwww.zhgopower.com%2Fproducts%2F11kv-sf6-gas-load-break-switch%2F[/a]
