Mid span joint is a transmission line accessory used to connect conductors. It connects conductor cables together in a transmission line.
As we all know, it is strictly forbidden to connect two conductors directly together in electrical wiring. In order to make the connection, we must use accessories such as mid span joint. The mid span joint keeps the cable intact and forms a reliable connection for maximum safety.
1. Reliability of conductor connections, ensuring strong wire connections and low resistance.
2. Durability, able to withstand current and temperature changes during power transmission.
3. Protection, to protect the conductor connection from damage caused by the external environment.
1. Installation position, a suitable position should be selected for installation in accordance with the wiring requirements and safety specifications of the conductor.
2. Fixing method, appropriate fixing method should be adopted to ensure the solidity of the mid span joint of the conductor.
3. Insulation treatment, the connection between the mid span joint and the conductor should be insulated to prevent current leakage or short-circuit.
