Misunderstanding of wire and cable

This is a fairly common misconception that a considerable number of users and even some companies use wire and cable. In order to save money and ignore safety, some users select low-quality wires and cables that are low in price, have no guarantee of quality, and have a large potential for accidents. We know that due to the safety of wires and cables and other factors, the prices of wires and cables cannot meet the requirements of some users. However, some individual private enterprises cannot produce wires and cables that meet the requirements of national standards in the selection of materials, production techniques, and testing methods. Its safety will not be guaranteed, and it will be added to the short-barreled rice to lower prices. Fill the market and cater to some users. Therefore, users are kindly requested not to cope with cheap wire and cable.

Second, wire and cable are not properly shaped.

Some users have insufficient understanding of their own electrical appliance use requirements and environmental conditions. They often do not have sufficient understanding of the scope of use, requirements and performance of wire and cable models and often choose the wrong model. For example, in front of a furnace of a steelmaking plant, its power is a motor, and the temperature in front of the furnace is as high as 800°C to 900°C. Under such environmental conditions, due to the particular requirements of the plant for wires and cables, Nothing is known, so the general general purpose rubber sheathed flexible cable is used to charge the YC type. As a result, the use time is short and the jacket is burned, which affects the production and wastes the economy. After consultation, the use of fire-retardant flame-retardant cable, reducing the replacement of the cable bitter and economic losses, to ensure the normal production of the enterprise. In some important departments, high-rise buildings, computing centers, chemical industry, public entertainment venues, and personnel concentration, flame-retardant or fire-retardant cables with fire-fighting functions must be used; the Ministry of Coal specifies that the cables used in deep coal mines must be flame-retardant; There are also special performance requirements such as elevator cables, welding machine cables, and motor lead wires. In the actual use of these special wires and cables with special requirements, some enterprises, especially individual enterprises, often have insufficient knowledge of them and refuse to use them; some companies ignore the requirement that the cables used in the deep wells of coal mines must be fire-retardant. Instead, they purchased general purpose rubber-covered flexible cables; there were also some karaoke halls and personnel that installed some general wire and cable that did not have the fire fighting function, causing great potential for accidents.
