Introduction to Misunderstandings in the Use of Wires and Cables

Some users or some enterprises have common misconceptions when using wires and cables. Some users, in order to save money, neglect quality and choose inferior wires and cables that are low-priced, have no guarantee of quality, and pose a high risk of accidents. We know that due to the reliability of wires and cables and other factors, the price of wires and cables cannot meet the requirements of some users. However, some individual and private enterprises are unable to manufacture wires and cables that meet standard requirements in terms of material selection, production processes, and inspection methods, and their reliability cannot be guaranteed. In addition, they focus on short lengths and meters, flooding the market with low prices to cater to some users. Please do not covet cheap wires and cables.

Some users have insufficient understanding of their electrical appliance usage requirements and environmental conditions, and often choose the wrong model due to insufficient knowledge of the scope, requirements, and performance of wire and cable models. For example, the slag transport truck in front of a steel plant is powered by an electric motor, and the temperature in front of the furnace is as high as 800 ℃~900 ℃. Under such environmental conditions, the plant knows nothing about the special requirements for wires and cables, so it chooses to use general rubber sheathed flexible cables to fill the YC type. As a result, the service time is short, and the sheath is burnt, which not only affects production but also wastes the economy. After consultation, fire-resistant and flame-retardant cables were selected to reduce the pain and economic losses of cable replacement, ensuring the normal production of the enterprise.

Fire-retardant or fire-resistant cables with fire protection functions should be used in important departments, high-rise buildings, chemical facilities, public entertainment venues, and places with concentrated personnel. The Ministry of Coal stipulates that cables used in deep coal mines must have flame retardancy. There are also special performance requirements for elevator cables, welding machine cables, motor wires, etc. In practical use, some enterprises, especially individual enterprises, often have insufficient understanding of these special wires and cables with special requirements and refuse to use them; Some companies ignore the requirement of the Ministry of Coal that cables used in deep coal mines must have flame retardancy, and instead purchase general rubber sheathed flexible cables; Some karaoke parlors and crowded places also install general wires and cables that do not have fire protection functions, causing serious accident hazards.
