What are the construction standards for equipotential installation
Installation, with the help of some tools, so the installation should be prepared in advance of the materials and tools, such as: steel plate, steel, copper, BV wire, etc., the quality of the product should be qualified.
1, installation requirements: when connecting the equipotential, we should carefully look at the welding part of each conductor, there can be no biting edges or the phenomenon of air holes on the surface.
2, if it is welding with iron equipotential, it should be noted that the length can not be less than 2 times it, so pay special attention to this point in the construction, to avoid the impact on the equipotential installation.
3, equipotential connection, should try to reserve sufficient contact area in the conductor connection, but also to ensure that the contact surface conductivity is good.
4, if the connection line is buried in the ground, can not use copper bare wire, should use steel conductor, and also for anti-corrosion treatment. Generally in the weld to do two anti-corrosion treatment, the connection between the conductor can not be crimped with bolts.
5, when the equipotential in the connection of the terminal board, must be kept solid, and the contact surface can not appear corrosion.
6, when the equipotential line and other pipe connection, in the pipe has a plastic connector, you can do spanning treatment.
7, if the local installation of equipotential in the bathroom, be careful not to connect with the external PE line.
Summary: The above is about the role of equipotential terminal box what are the relevant content, I believe we all understand it! Equipotential is now an important part of the building appliances, it will protect the trunk line in the building, heating and other parts of the linkage, can play a protective role.
