Standards For Using Industrial Connectors

1. Use voltage, current and frequency. According to whether the power supply used by the electrical equipment is single-phase or three-phase, confirm the number of heavy duty connector 6 pin. For single-phase power supply, select 3 poles, and for the win-line grounding in the three-phase power supply, select 4 poles, otherwise select 5 poles. Select the specifications according to the rated voltage, working current level and frequency of the equipment. China's AC power grid is usually three-phase 380V, single-phase 220V, and frequency 50Hz.

2. Use wires. The socket connected to the power cord should be covered to prevent electric shock. If the power supply is to be plugged into the socket of the device and the device input, a connector should be selected. Generally, the connector is connected to the end of the power supply line and has a cover to prevent electric shock. On the wired line, connect the input interface or receiving cable of the electrical equipment with heavy duty electrical contacts or appliance input socket.

3. Use environment. Generally speaking, such as conventional factory workshop rooms, splash-proof heavy duty industrial connector can fully meet the requirements. In harsh environments or places where water may be immersed, such as cement workshops, muddy construction sites, container terminals, etc. In places where there is a lot of dust or water intrusion, IP67 anti-immersion heavy duty male female connector should be used to ensure that the protection performance meets the requirements. The general heavy duty multi pin connectors has a plastic shell, which has good performance in all aspects and can be used in regular workplaces. Coal mines use heavy connector with black rubber shell. Some workshops with high working temperature and sparks, such as steelmaking and ironmaking workshops and foundries, should use heavy duty cable connectors with aluminum alloy shell.
