Industrial waterproof plugThe application of waterproof plugs is becoming more and more widespread, but safety issues are also increasing. For example, the contact resistance of industrial waterproof plugs is too high and generates heat. When the total contact area is less than the total area of the conductor, it is easy to cause the connecting hair to heat and overheat, leading to the burning of surrounding combustible materials and becoming a fire safety issue. So what is the reason for the excessive contact resistance of the joint? Below is a detailed analysis by Shenzhen Dongshengda, an industrial waterproof plug.

1. Copper core wires and aluminum cables are not connected according to the prescribed method, which poses a safety hazard.

2. If the transmission line is not twisted according to strict requirements, the connection of the connector is not easy to be firm and loose, leading to spark discharge and serious safety accidents.

3. Transmission lines, power switches, and high-power electrical appliances are connected by steel wire columns. Due to the complexity of engineering construction, there is no sealing ring on the wiring head, and the screw cap is not tightened, which can also expand the contact resistance and dissolve the conductor, causing molten beads to fall into stationary objects, causing safety accidents.

4. The iron core of the transmission line is not twisted, and some of the wool (wire core) is warped outward. After collision, a short circuit fault occurs, and the industrial waterproof plug is connected to the power supply, causing a short circuit fault and causing safety accidents.

5. The connectors of each phase are not separated, and the connector is torn apart by two different colors of short circuit faults, causing spark discharge, which is easy to cause safety accidents. Long term disconnection of the connector loosens the conductor junction, causing air oxidation dust environmental pollution. Safety accidents should be minimized at the interface as much as possible.
