Performance difference between aluminum alloy cable and aluminum core cable

Performance difference between aluminum alloy cable and aluminum core cable
The corrosion resistance of pure aluminum is better than that of copper, but the corrosion resistance of aluminum alloy is better than that of pure aluminum, because the chemical elements such as rare earth added to aluminum alloy can increase the corrosion resistance of aluminum alloy, especially the electrochemical corrosion resistance, which solves the problem of electrochemical corrosion of pure aluminum in the joint for a long time.

Different of flame retardant cable, halogen free cable, fire resistant cable

Flame retardant cable is characterized by delaying the spread of flame along the cable so that the fire does not expand. Whether it is a single cable or a bundle of laying conditions, the cable is known to burn when the spread of the flame can be controlled within a certain range, so you can avoid the fire caused by the major disasters, thereby improving the fire level of the cable line.

Understanding of cable protection resistance and protection testing in the market

Cable resistance refers to the maintenance measures taken to ensure that the resistance of the cable system meets the design requirements. During the use of the cable, due to the influence of the external environment, such as humidity, high temperature, vibration, etc., it is easy to cause accelerated aging of the cable insulation, resulting in the cable resistance not meeting the design requirements.

What is the difference between cross-linked polyethylene insulated cables and ordinary insulated cables?

Cross-linked polyethylene insulated power cable has good thermal-mechanical properties, excellent electrical and chemical corrosion resistance, but also has the advantages of simple structure, light weight, laying is not limited by the gap and so on. Currently widely used in urban power grids, mines and chemical plants and other places.

The difference between conductor shielding and insulation shielding

The conductor shield is used between the conductor and the insulating material. The insulating shield is extruded on the surface of the insulating material and interacts with the coaxial natural or synthetic tape and sheath (if any). Shielding materials are essentially semi-conductive materials because they act as a stress transition between the insulation and the conductor,

XLPE cable shield material characteristics?

The so-called "shielding" on the cable structure is essentially a measure to improve the electric field distribution. The cable conductor is formed by stranding a plurality of guide wires, it is easy to form an air gap between the insulation layer, and the surface of the conductor is not smooth, which will cause electric field concentration. A shielding layer of semi-conductive material is added to the surface of the conductor,
