Smart grid spawns smart cables, experts may have temperature sensing function

What should a “smart cable” look like? Some experts gave an example of whether the wire and cable can understand the conveying capacity through the color of the surface, can have a temperature sensing function, and the color display can be different at different temperatures. For example, if the wire is transported more than 1000 … Read more

Factors Affecting XLPE Insulation Thermal Shrinkage

The cross-linked polyethylene cable material (XLPE) can make the aggregate structure of the insulating material in a reasonable state through the cross-linking process, and can increase the long-term working temperature of the power cable to 90 ℃, and the instantaneous short-circuit temperature is 170 ℃ ~ 250 ℃. The performance remains unchanged while other performances … Read more

Repair Method of Poor Insulation Sheath

Scope of application When the PVC insulation cable and sheath layer of the wire and cable have local defects, they are allowed to be repaired, such as broken glue, collapsed pits, disconnections, wrinkles, bumps, ears, edges, breakdown, joints, etc. Materials and equipment used: The raw materials use plastic strips, skins, blocks and tubes of the … Read more

Performance Comparison of Copper and Copper Clad Aluminum Cable

Cables are divided into different inner conductors. There are two main types, one is pure copper material and the other is copper clad aluminum material. The English name of copper-clad aluminum is Copper Clad Aluminum, so copper-clad aluminum conductors are also often called: CCA conductors. Copper-clad aluminum composite wire was first introduced by Germany in … Read more

Difference between Fire-Resistant and Flame-Retardant Cables

1 The difference in principle Fire-resistant cables have different principles from flame-retardant cables. The flame-retardant principle of halogen-containing cable is based on the flame-retardant effect of halogen, and the flame-retardant principle of halogen-free cable is to reduce the temperature of the water to extinguish the fire. Fire-resistant cables rely on the fire-resistant and heat-resistant characteristics … Read more

What is Bare Wire & Bare Conductor ?

Cable products with only conductors without any insulation layer are called “bare wires and bare conductor products”. In order to ensure the current flow along the wire and electrical safety, external insulation suitable for the line voltage must be installed during installation, such as space separation, insulator support, etc. Therefore, this type of product itself … Read more

What is Difference Between XLPE Cable and PVC cable?

Polyethylene abbreviated as PE, it is a polymer of ethylene, non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, and good electrical insulation. It is suitable for packaging materials for food and medicine, Making food utensils, medical equipment, and insulating materials for the electronics industry, etc.;PE cable become the better choice economically. Polyvinyl … Read more
