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 new material we are going to talk about this time may bring new changes to the material field of aluminum alloy cables. It is magic angle graphene. Some people say, isn’t it just graphene? I already knew it. In fact, it is really not. The magic angle graphene we are going to talk about … Read more
Conductor shielding layer (also called inner shielding layer, inner semi-conductive layer) ①Conductor shielding layer is a non-metallic layer squeezed on the cable conductor, and is equipotential with the conductor, and the volume resistivity is 100~1000Ω•m. Equipotential with conductor. ② Generally, low-voltage cables of 3kV and below have no conductor shielding layer, and medium- and high-voltage … Read more
Since the beginning of the 1990s, China’s contribution to aluminum-cored steel reinforced Conductor (ACSR ) has increased significantly, and at the same time, the export volume has also soared.As the main electrical material for long-distance transmission, AAAC conductor will also face major development. The wire has the advantages of good flexibility, good reliability and high … Read more
The biggest advantage of corrugated aluminum sheathed cross-linked cables is light weight and large short-circuit thermal stability. In a system with a slightly longer short-circuit current, the standard thickness of the aluminum sleeve can meet the requirements. For example, when the thermal stability is not enough in the calculation, the aluminum sleeve can be thicker … Read more
Recently, the optical communications section is relatively hot. In the process of communicating with friends, it seems that many people are very concerned about the impact of the Ministry of Commerce on the impact of the anti-dumping of optical fiber preforms from US and Japanese manufacturers on domestic enterprises, especially worried about the implementation deadline … Read more
Aluminum alloy cable (abbreviation: alloy cable) is different from the traditional copper core cable. This aluminum alloy cable uses high elongation aluminum alloy material. The pure aluminum is added with iron and other materials, and undergoes a compact stranding process and special Annealing treatment can “squeeze” the voids in the alloy aluminum to reduce the … Read more
Matters needing attention in Electrical cable installation: 1. Keep a distance of 2m when the mine cable is installed in parallel with the heating pipeline, and keep 0.5m when crossing. 2. When the cable is installed in parallel or across other pipes, a distance of 0.5m must be maintained. 3. When the cable is directly … Read more
In recent years, silane cross-linked polyethylene cable material (hereinafter referred to as XLPE) has become the leading material for low-voltage cross-linked cable insulation because of its simple manufacturing equipment, mature technology, convenient operation, and low overall cost. At present, the commonly used XLPE is the two-step XLPE. When the cable factory produces the insulated core, … Read more
