This paper introduces the standard and identification method of national standard cable. So, what kind of cable is produced in accordance with national standards? How to identify and distinguish different qualities of cable? What quality level does "enterprise standard/non-standard", "market national standard" and "resistance national standard" represent? Whether you are a wire and cable sales staff, or purchasing staff, I believe this article will help you.

Cable resistance refers to the maintenance measures taken to ensure that the resistance value 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.,

Cable parallel connection is a common wire connection method, which can improve the carrying capacity of the wire and ensure the safe and stable operation of the wire. When the cable is connected in parallel, attention should be paid to the matching of the cross-sectional area of the wire, the limitation of the number of combined groups, the method of wiring, the control of the distance between the wires and the fixing of the cables to avoid the occurrence of wire accidents. Let's take a look at

The difference between soft-sheathed cables and hard-sheathed cables is mainly reflected in the following aspects:

Photovoltaic wires, also known as photovoltaic cables or photovoltaic power cables, are wires used to connect photovoltaic power generation systems. This wire is usually made of metal materials with good electrical conductivity, such as copper or aluminum, and has a variety of advantages, such as high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV protection, flame retardant and environmental protection, long service life. They are widely used in various
