Wire load is a concern before we buy wires. At present, the wire specifications commonly used in our life include 1 square wire, 1.5 square wire, 2.5 square wire, 4 square wire, 6 square wire, etc., so how many watts can these wires load? Let’s look at the number of watts the 1, 1.5, 2.5, … Read more
The function of air switch in the circuit is to automatically break the circuit when overload, short circuit and voltage loss exceed the allowable limit occur, and to make and break the circuit infrequently under normal conditions. The function of the wire should be able to bear the needs of the maximum load current, and … Read more
Compared with ordinary aac cables, environment-friendly cables have the following advantages: The first is that it has high flame retardancy. As we all know, the flame retardancy of cables is very important. For cables with safety and fire protection requirements, cables are not easy to burn and fire, and can prevent the expansion of flame. … Read more
At present, there are various on-site treatment methods for the armor layer of low-voltage direct-buried cables, including single-ended grounding and two-end grounding. There are also those that are not grounded at both ends. According to the different treatment methods of the steel tape armor at both ends of the field cable, after the cable fails, … Read more
As the second largest manufacturing industry in China after automobile manufacturing, the wire and cable industry should also play a leading role in environmental protection. In recent years, environmentally friendly cables have become more and more popular in the market. In developed countries such as the European Union, non-environmental protection has been banned. Cables, China … Read more
Due to changes in the environment in which Power Cables are laid and the application of new materials for cables and their accessories in the cables, it is increasingly difficult to locate faults on the power cable site. The difficulty of field cable fault location is mainly reflected in the fault location of directly buried power … Read more
Power Cables are divided into different inner conductors. There are two main types, one is pure copper material and the other is copper-clad aluminum material. The English name of copper-clad aluminum is Copper Clad Aluminum, so copper-clad aluminum conductors are also often called: CCA conductors. Copper-clad aluminum composite wire was first introduced by Germany in … Read more
Many people are full of curiosity about submarine cables. Submarine cables are actually a kind of long-distance optical fiber. Generally, long-distance optical cables in the world use submarine cables. So how do submarine cables be laid? Compared with submarine cables, the laying of terrestrial cables is much simpler. You only need to dig the cable … Read more
1. Preparation of raw materials The preparation of raw materials requires warm glue and glue cutting. The weighing of raw materials is a crucial process of preparation. 2. Plasticizing Rubber has high elasticity at room temperature and is not easy to process. Therefore, it is necessary to change its high elasticity to make it have … Read more
There are two key links in the wire and cable manufacturing industry, namely theAluminum conductors steel-reinforced production link and the wire and cable testing link, especially the wire and cable testing link. This is the last stop for quality control and a comprehensive assessment of the performance of wires and cables. The burning test of … Read more
