What is the relationship between the cross-sectional area of the cable and the current of the cable, and what is the calculation formula?
Read moreWires are usually called “cables”. They are carriers for transmitting electrical energy and are the basic conditions for forming loops between electrical equipment. The important components of wire transmission are usually made of copper or aluminum materials. The cost of wires used in different applications is different. For example, precious metal materials are rarely used […]

Introduction to the basic knowledge of conductor shielding layer and metal shielding layer
Read moreConductor shielding layer (also called inner shielding layer, inner semi-conductive layer) The conductor shielding layer is a non-metallic layer extruded on the cable conductor, which is equipotential with the conductor and has a volume resistivity of 100~1000Ω•m. Equipotential with the conductor. Generally, low-voltage cables of 3kV and below do not have a conductor […]

What is the difference between cable insulation materials PE, PVC, and XLPE?
Read moreAt present, the cable insulation materials used in cable production are roughly divided into three categories: PE, PVC, and XLPE. The following introduces the differences between the insulating materials PE, PVC, and XLPE used in cables. Explanation of the classification and characteristics of cable insulating materials PVC: Polyvinyl chloride, a polymer formed by the […]

How to meet cable construction requirements?
Read moreCable construction requirements Before laying the cable, check whether the cable has mechanical damage and whether the cable reel is intact. For cables of 3kV and above, a withstand voltage test should be performed. For cables below 1kV, a 1kV megohmmeter can be used to measure the insulation resistance. The insulation resistance value is generally not […]
