Analysis and treatment of cable insulation breakdown
The vigorous development of urbanization has made urban space more and more tense. Because of the demand of industrial enterprises, cable entry has become an inevitable choice. However, in recent years, external insulation damage and installation quality have caused cable insulation breakdown and even explosion, which have become major accidents in the power grid. In general, there are several reasons for cable insulation breakdown.Jul 12,2018

What are the advantages of copper core cable and aluminum core cable?
Copper core cables have more advantages than aluminum core cables: 1. Low resistivity: The electrical resistivity of the aluminum core cable is about 1.68 times higher than that of the copper core cable. 2. Good ductility: The elongJul 07,2018
Analysis of connection method of aluminum core cable conductor
Copper is the main conductor material used in wire and cable products, so the copper core code is written in T, except for bare wires and bare conductor products. Bare wire and bare conductor products, power cables, and electromagnetic wire products do not indicate large class codes. Wires and cables for electrical equipment and communication cables are not listed, but subcategories or series codes are listed.Jul 06,2018

Common wire and cable specifications
Wire and cable are used to transmit electrical (magnetic) energy, information, and wire products that convert electromagnetic energy. The generalized wire and cable is also referred to simply as the cable, and the narrowly defined cable is the insulated cable. It can be defined as: an assembly consisting of the following parts; one or more insulated wire cores, and their respective possible covering layers. Protective layer and outer sheath, cables may also have additional uninsulated conductorsJun 27,2018

Difference between YJV cable and VV cable
The difference between YJV cable and VV cable is that YJV and VV are two kinds of cables with different insulation materials. General indoor permanent projects tend to choose YJV cables. VV cables are generally used for low-voltage systems and YJV cables are used for high-voltage systems. YJV cable is superior to VV cable in temperature resistance, pressure resistance and corrosion resistance.Jun 20,2018
