Since the founding of the People’s Republic of China, China has realized the important role of wires and cables in the future economic development, so it has spent a lot of … 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
1. Keep a distance of 2m when the mine AAAC cable is installed in parallel with the thermal pipeline, and keep 0.5m when crossing. 2. When the cable is installed in parallel or across other pipes, a distance of 0.5m must be maintained. 3. When the cable is directly buried, the depth of the 1-35kV … 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

The demand for high-voltage power cables has been increasing in recent years, and cable companies have also entered the market. The main technology for … 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
In daily life, many people will see high-voltage power cables in the suburbs. They are often erected in mid-air, but many people may not observe carefully. Many of the high-voltage wires that are erected in the air are bare wires. The so-called bare wires are not insulated. The cable of the skin. Usually the wires … Read more
