The generation of GB cable fault test is caused by the laying and application of cable, and the accurate positioning of cable fault test is different with the laying method of cable, and the difficulty coefficient of accurate positioning is gradually increasing. Among them, the accurate positioning and search of cable bridge, tunnel construction and ditch open matching method are relatively simple, while the accuracy and search coefficient of direct buried method is relatively difficult. When th

The generation of wire and cable fault test is caused by the laying and application of cable. The accurate positioning of cable fault test varies with the laying method of cable, and the difficulty coefficient of accurate positioning is gradually increasing. Among them, the accurate positioning and search of cable bridge, tunnel construction and ditch open matching method are relatively simple, while the accuracy and search coefficient of direct buried method is relatively difficult. When the co

Developed capitalist countries prohibit the application of non-environmental protection cable, of course, in our country also attaches great importance to this industry. In China, the relevant laws and regulations prohibit the use of polyethylene cables and wires in key engineering construction, and it is necessary to use low-smoke halogen-free cables and high-density polyethylene cables and wires to prevent a lot of smoke and hydrogen when a fire accident occurs, resulting in casualties.

The national standard cable is literally understood to be a cable and wire produced strictly in accordance with national industry standards. In our country, there are clear regulations on the appearance of cable lines, impact toughness, insulation layer of wire sheath, compressive strength, wire resistance and other levels, different types of cable lines have different national industry standards, the key has the following categories:

There are many kinds of wire and cable on the market, and a type of wire and cable is also divided into many kinds. I believe everyone should have seen such a line, many people like to call it the fire line, twisted pair, flower line and so on. So, what does this line do? Follow Qingdao Tianxing cable to understand this kind of wire!

The national standard cable is the most widely used standard cable in China, and its technical standards are very delicate. The cables and wires required for application in various fields have very established model specifications, which are explained in detail by Shengwei Electrical Equipment.
