How is the insulation protection of industrial socket achieved

The insulation protection of industrial sockets is to prevent electric shock accidents caused by current passing through the air gap between the plug and the socket. In industrial environments, due to the high power supply voltage, the insulation protection of the socket is particularly important.
First, the insulation protection of industrial sockets involves the selection of insulating materials. The insulating material needs to have good insulation properties and can effectively prevent the current from passing through the material and causing electric shock. Common insulating materials include plastics, rubber, and insulating glue. These materials have high insulation impedance and can provide effective insulation protection.
Secondly, the insulation protection between the plug and the socket of the industrial socket also needs to consider the structural design of the plug and the socket. A separate insulation structure is usually used between the plug and the socket, that is, there is a certain gap between the plug and the socket, and this gap is filled with insulating material to play an insulating role. The selection of insulating materials and the design of the insulation structure need to take into account the power supply voltage and the size of the plug and socket to ensure sufficient insulation distance and insulation performance.
In order to ensure the insulation protection performance of the industrial socket, insulation testing is an essential step. Insulation testing can be performed by using an insulation resistance tester, which can measure the insulation resistance between the plug and the socket. Insulation resistance is an important indicator for measuring insulation performance, and the insulation resistance is usually required to reach a certain value to ensure the effectiveness of insulation protection. Insulation testing can be performed during the production process to ensure that each industrial socket meets the insulation requirements.
In order to facilitate users to identify and judge the insulation performance of industrial sockets, industrial sockets usually have insulation levels or insulation marks on plugs and sockets. The insulation level is determined according to international standards or industry standards, and usually different levels represent different insulation performance. Insulation marks can help users choose the right industrial socket and ensure that it meets specific insulation requirements.
