General principlesThe rated voltage of the cable is equal to or greater than the rated voltage of the network where it is located, and the maximum working voltage of the cable must not exceed 15% of its rated voltage. In addition to the use of copper core cables in places that require movement or se... READ MORE
Cable: When the phone converts the acoustic signal into an electrical signal and then transmits it to the switch via the line, the switch transmits the electrical signal directly to the other phone via the line for answering. The transmission line during this conversation is the cable. The main part... READ MORE
If the cable is to be stored for a long time, the following considerations should be taken according to the location of the cable:1. Under the eaves. The standard LAN cable can be used only when the cable is not directly exposed to sunlight or ultra-high temperature. It is recommended to use pipes.2... READ MORE

1. When the cables cross each other, the high-voltage cables should be under the low-voltage cables. If one of the cables is protected by a pipe or separated by a partition within 1m before and after the intersection, the minimum allowable distance is 0.25m.2. When the cable is close to or crossing ... READ MORE
With the rapid development of power cable buried laying engineering, higher requirements are put forward for cable protection. The cable protection sleeve is made of polyethylene PE and high-quality steel pipe, which is pre-treated by sandblasting and shot blasting, dipped or painted, and heated and... READ MORE
