How many rumors do you know about wires and cables?

The rapid development of the Internet age has not only brought convenience to everyone’s life, but also brought new challenges to our social management. In particular, we have seen the rapid spread of rumors. I believe you can distinguish many rumors, but how many rumors about wires and AAAC Cables have you heard? Can you … Read more

Why do low-voltage power cables use four cores?

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

Operation and maintenance of protective layer protector

In order to reduce the induced overvoltage of the metal sheath of single core AAAC Cable lines of 110kV and above, a protective layer protector should be installed between the ungrounded end of the metal sheath and the earth. In case of system trip or line lightning stroke, special patrol shall be conducted for cable … Read more

Testing of sheath and corrosion protection

The intact cable sheath can effectively protect the insulation: it can prevent liquid water from immersing in the insulation, and the enclosed metal sheath can also prevent moisture from diffusing into the insulation, so it can obviously prevent the formation of water branches in PE / XLPE insulated cables. The sheath and anti-corrosion layer test … Read more

Cable fault detection and search method, you should understand

For direct short circuit or broken cable fault, the multimeter can be used to measure and judge directly; For non direct short circuit cable fault and grounding AAC Cable fault, the insulation resistance between cores or insulation resistance between cores to ground can be measured by megohmmeter, and the type of cable fault can be … Read more

Difficulties in locating cable faults

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

Plastic Extrusion and Traction Speed of Cable Technology

The rate of plastic extrusion According to the flow rate analysis of the viscous fluid in the material conveying and homogenizing section of the ABC conductor,  the flow rate of the plastic (that is, the extrusion speed) is proportional to the screw speed, and the screw speed is an important operating variable to characterize the … Read more

There are Six Materials for the Cable

We are commonly used are super five types of lines or six types of lines, although they are all cable, but the cable material is also divided into several kinds, most of them are in line with the national conditions of production!When buying a line, don’t be a pit!Don’t be greedy for cheap! First, four … Read more
