Introduction to the development history of power cablesThe use of power cables has been around for more than a hundred years. In 1879, the American inventor T.A. Edison wrapped jute around a copper rod and put it into an iron pipe, and then filled the asphalt mixture to make a cable. He laid the cable in New York and created undergrou...
Analysis of cable line fault causes and countermeasuresShort-circuit fault: There are two-phase short-circuit and three-phase short-circuits, which are mostly caused by hidden dangers left in the manufacturing process.Grounding fault: A certain core or several cores of the cable break down to the ground. The insulation resistance is lower than 10k...
Introduce the difference between the YJV power cord and the VV power cordYJV and VV are two kinds of power cables with different insulation materials. Generally, indoor permanent projects tend to choose YJV power cables. VV power cables are generally used in low-voltage systems, and YJV power cables are mostly used in high-voltage sy...
Shielded Polyethylene Insulated Electric Cable Shield IntroductionThe role of shielding on medium-pressure cross-linked polyethylene is very important. It can improve the uniformity of electric field distribution. According to the standard understanding, the shielding is divided into non-metallic shielding (conductor shielding, insu...
Description of Cable Characteristics and Requirements for Use SitesVV: PVC Insulated, PVC Sheathed Power CableCan be laid indoors, in tunnels, cable trenches, and pipelines, flammable and severely corroded, but can not withstand mechanical external forces. It is necessary to bear the external force of the machine and add the steel tape armor.Y...

Ways to deal with moisture in power cablesAt present, the power cables used in construction mainly use YJLV22 series cross-linked aluminum core cable and YJV22 series cross-linked copper core cable (10KV). Compared with overhead lines and old-fashioned oil-filled cables, this type of cable has good insulation performance and allows high opera...
In China, the land is vast, and different temperature zones are distributed from the south to the north, and there is often a relatively large temperature difference between the north and the south.Therefore, when selecting materials for integrated wiring, we should pay attention to the minimum and maximum temperatures of wiring places.Choose the cabl...
The main advantages and disadvantages of power cables compared to overhead linesPower cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station outlet lines, internal power supply for industrial and mining enterprises, and power lines under river...
