1. The Street Lamp Junction box complies with IEC60947-7-1 and GB14048.7.1 standards;
The outdoor pinning Lightning protection hardware is similar to the (line) pin insulator. The difference is that the former head is glued with a metal cap, and the supported live conductor is fixed by a threaded hole in the cap and a certain fitting, and the latter generally depends on the porcelain head.
In order to prevent dust and other dirt from adhering to the surface of the insulator, the Suspension Clamp is formed by the voltage across the insulator, that is, creepage.
The high pressure bundle type tension clamp is used together with the high pressure rod suspension type bundle type tension clamp. The main purpose is to protect the high pressure bundle type tension clamp surface from being burnt.
In order to prevent dust and other dirt from adhering to the surface of the High voltage cable clamp, the formation path is broken by the voltage across the High voltage cable clamp, that is, creepage.
Glue waterproof junction box is mainly used for the weakest link in transmission lines. Due to the quality of intermediate joints and installation defects, or due to moisture, overload and other external forces, cable joints often have explosion accidents.
