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

Advantages of high temperature superconducting cable

Compared with traditional power cables, superconducting cables have the advantages of low loss, large transmission capacity, small ABC Cable volume and strong system security and stability. Cold insulated HTS cables have low mutual electromagnetic influence and thermal field influence, and have stable current carrying capacity. They have great development prospects in underground cable systems in … Read more

Current situation of power cable and accessories

Insulating materials and shielding materials for power cables, especially materials for high-voltage and ultra-high-voltage XLPE insulated AAAC Cables, are prominent “soft ribs” or “short boards” of China’s cable industry in this field (all sheath materials have been localized). 1. Medium and low voltage power cable materials Medium and low voltage power cables are mostly insulated … Read more

Underground cable is the trend of urban development

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

How to solve these problems in PVC

1、 Troubleshooting of common faults in injection molding of ACSR Cables Under note Fault analysis and Troubleshooting: (1) The temperature of the melt is too low. The forming temperature should be increased properly. (2) Forming cycle is too short. It should be extended appropriately. (3) Insufficient injection pressure. It should be improved appropriately. (4) The … Read more

What is the difference in the temperature resistance of cables?

UL standard In UL standard, the common temperature resistance grades are 60 ℃, 70 ℃, 80 ℃, 90 ℃, 105 ℃, 125 ℃ and 150 ℃. How do these temperature ratings come? Is it the long-term operating temperature of the conductor? In fact, these so-called temperature ratings are called rating temperature in UL standards. It … Read more

What is the difference between copper conductor and copper alloy cable?

Copper bar is the main raw material of AAC Cable industry. There are two main production methods: continuous casting, continuous rolling and continuous casting. Due to different processes, the oxygen content and appearance of copper rods are also different. When the oxygen content is lower than 10ppm, it is called oxygen free copper rod; When … Read more

Discussion of the cable production process: conductor stranding

Discussion on the cable production process: conductor twisting and twisting : the process of twisting many small diameter monofilaments into a large cross-section conductive core according to certain rules. 1. There are two types of twisted wires: normal twisted wires and irregular twisted AAC Cables. Ordinary strands can be divided into ordinary concentric single stranded … Read more

Tips for ACSR cable fault location

The occurrence of ACSR Cable 336.4 MCM  faults is accompanied by the laying and use of cables. The location of cable faults varies with cable laying methods, and the difficulty in locating is gradually increasing. Among them, the positioning and searching of bridges, tunnels, and trenches are relatively simple, while the direct-buried method is the … Read more

Overhead lines need “nine checks”

The inspection of overheadcable is one of the basic contents of the operation and maintenance of overhead lines. Defects can be found in time through inspections so that preventive measures can be taken to ensure the safe operation of the line. Usually, line inspectors should do “nine inspections” when inspecting overhead lines. Check the pole … Read more
