The low-voltage power grid in urban residential areas generally adopts the three-phase four wire system. The four core cable used in the low-voltage power grid, except for the three-phase conductor, is called the neutral wire. It can pass through the unbalanced current of three-phase AC and has the function of protective grounding. Three core cable … Read more
In the production process of rubber sheathed AAC Cable, there are often appearance defects, such as unsmooth surface; Clinker particles (early vulcanized rubber particles) or impurities on the surface; Scratch and scratch on the surface of wires and cables; Surface collapse; There are hemp patterns on the surface. The following are five common causes of … Read more
Based on the underground cable informatization model developed by China Electric Power Research Institute, the “perspective” management of underground cables can significantly improve the design, construction, operation and maintenance and management level of underground ACAR Cable lines. Firstly, this technology can make the route planning and design of underground cable engineering more reasonable. Using three-dimensional … Read more
Install “perspective eyes” for underground cables In many cities in China, especially in some metropolises or new urban areas, power towers and wires are basically invisible, but thousands of households can use electricity normally. Where does people use electricity come from? In fact, this mainly depends on underground cables to transmit electric energy. Underground cable … Read more
