Coaxial cable is commonly used by cable operators, telephone companies, and Internet providers around the world to carry data, video, and voice communications to customers. It has also been widely used in homes. Coaxial cable has been around as a technology for a long time (since the early 20th...

Once the cable catches fire, we all know that the consequences will be disastrous, not only causing economic losses, but also people's personal safety. Especially where cables are used, such as aerospace, radar power stations, transportation tracks, and military fields. If there is a fire, the...

High temperature wire is widely used in daily production and life, but what problems should be paid attention to when using high temperature wire? Today, the editor will share with you the issues that should be paid attention to in the high temperature line. Problem 1 that should be paid...

White copper, brass, red copper (also known as "red copper"), and bronze (blue-gray or gray-yellow) are distinguished by color, among which white copper and brass are very easy to distinguish; red copper (pure copper, impurities Cupronickel is a copper alloy with nickel as the main additive...

Copper rods are the main raw materials in the cable industry. Due to different production processes, the oxygen content and appearance of the copper rods produced are different. Due to the different manufacturing methods, it is divided into low-oxygen copper rods and oxygen-free copper rods,...

According to different occasions, the cable structure is also different. In the case of shielding interference, shielded cables are widely used, so when choosing shielded cables, should you choose copper wire shielding or copper tape shielding? About copper wire shielding and copper tape...

Ethernet cable, according to different prices and applications, the internal cable material will also change. Generally, we call the network cable oxygen-free copper network cable, but there are also other network cable names, such as copper-clad copper, copper-clad silver, copper-clad steel,...

Copper is the main raw material of the cable industry, but it is easily oxidized to black CuO by oxygen in the air under acidic conditions. Exhaust gas, chloride and other acids, alkalis, salt particles and dust, etc., these harmful substances dissolve in water film or water droplets to form...

What is a shielded wire? Definition: A conductor wrapped with a conductor outside the conductor is called a shielded wire, and the wrapped conductor is called a shielding layer, which is generally a braided copper mesh or copper moor (aluminum). Function: prevent interference signals from...

1. Solution to discoloration of copper tape (1) Control the concentration of acid solution during pickling. In the case of washing off the oxide layer on the surface of the annealed copper strip, a high acid concentration does not make any sense. On the contrary, if the concentration is too...

Understanding and being familiar with "Causes and Analysis of Copper Wire Disconnection" will help the wire drawing factory to make a reasonable and objective analysis and judgment on the reasons for copper wire disconnection in the production process. Types of broken wires and their discussion...

Stranding includes not only the stranding and bundling of conductors, but also the stranding (cabling) of insulated cores, as well as the stranding of cable core components. Based on this, only the stranding and stranding of conductors are described and discussed in this paper. , that is, the...

In the manufacturing process of the shielding layer, there are many correct or incorrect processes, one of the most important parameters is the braiding angle of the shielding layer. In cables used in energy chains, the load on the shield of the outer diameter of the cable must be taken into...

Heat resistance and high temperature wire and cable are usually determined by two standards. The first is that the operating temperature of the wire and cable is relatively high, and the cable can transmit data, data signals or electrical energy normally under high temperature for a long time;...

The conductor of the wire and cable is the most important part of the wire and cable. The conductor is the basic element to realize the function of transferring electric charge. Generally speaking, there are two kinds of wire and cable, copper conductor and aluminum core conductor. The latest...

Insulation resistance The insulation resistance of fireproof cables depends to a large extent on the moisture content in the magnesium oxide. Under standard conditions, when the humidity does not exceed 0.4% (allowable value). The insulation resistance of compressed magnesium oxide is higher...

"Fiber-optic cables instead of copper? Is this really possible?" With the continuous improvement of bandwidth requirements in the network era, there is a saying that copper fades into light, and optical fibers have gradually replaced traditional copper cables and become the mainstream of the 5G...

The production of copper single wire is a problem that all cable manufacturers are very concerned about, because the quality and efficiency of wire drawing directly affect the process of the manufacturer's subsequent procedures, and play a pivotal role in the quality of the cable. several...

Mine coaxial cable is divided into four layers from inside to outside: central copper wire, plastic insulator, mesh conductive layer and wire sheath. The central copper wire and the mesh-like conductive layer form a current loop. It is named because the central copper wire and the mesh...

Generally speaking, the service life of wires and cables is not less than 20 years, but external factors often affect the length of their service life, such as insulation layer damage, aging, corrosion, etc. In the actual use process, the reason for cable aging is In all respects, how to prolong...
