Power cables are usually rope-like cables formed by twisting several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer layer has a highly insulating coating. They are mostly erected in the air, underground, or underwater for telecommunications or power transmission. Cables … Read more
The sheath is the “skin” of the wire and cable and the appearance that people look directly at. It must be smooth and round, uniform in color, not eccentric, not damaged, free of impurities, free of bubbles, and not flattened, twisted, etc., except In addition to being unsightly, the thickness of the sheath also has … Read more
The Aerial Bundled Cable series products are composed of pressed copper, aluminum (aluminum alloy) conductors, inner shielding layer, weather-resistant insulating material and outer shielding layer. They have both the power transmission characteristics of power cables and the strong mechanical properties of overhead cables. Compared with bare wires, this product has the advantages of small laying … Read more
Commonly used plastics for wires and cables include polyethylene, cross-linked polyethylene, polyvinyl chloride, polypropylene, polyolefin, fluoroplastics, nylon, etc. Polyethylene is currently the most widely used plastic with the largest consumption. From the data in the table, it can be seen that polyethylene has low meson loss, high resistivity, high breakdown field strength, good weather resistance … Read more
Cross-linked cable is the abbreviation of cross-linked polyethylene insulated cable. It is composed of conductor, insulating material, internal and external semi-conductive material, sheath material, shielded copper tape, armored steel tape/steel wire, inner lining, isolation sleeve, filling material, etc. Part of the cable. Different components have their own usage requirements and characteristics. For example, XLPE insulated … Read more
AAAC Condutors are the basic facilities for transmitting electrical energy to every household or unit. Without it, we can enjoy modern life without electricity. However, precisely because it is placed in our work and living environment, it also brings certain hidden dangers to our lives, lives and work. There are countless fires caused by overheating … Read more
1. The main features of overhead insulated conductors (ABC cables) have good insulation performance. Overhead insulated conductors have an extra layer of insulation and have superior insulation performance than bare conductors, which can reduce the distance between lines, reduce the insulation requirements for line supports, and increase the number of circuits erected on the same … Read more
I don’t know whether to buy ASTM 477 MCM ACSR Cable online or in physical stores. It mainly depends on which part of the demand you need to meet. For users with higher quality requirements, you can buy them in physical stores. After all, you can get in touch with the real thing. , Specifications, voltage, … Read more
Aluminum alloy power conductor is a new type of material power cable that uses AA8030 series aluminum alloy material as the conductor and adopts special roll forming wire stranding production technology and annealing treatment. Alloy power cables make up for the shortcomings of pure aluminum cables in the past. Although the electrical conductivity of the … Read more
The advantage of aluminum alloy cable over ordinary cables is that under the same volume, the actual weight of aluminum alloy is about one-third of copper. According to this calculation, under the premise of meeting the same electrical conductivity, the length of the aluminum alloy cable with the same weight is twice that of the … Read more
