Wire and cable use errors Introduction
This is a fairly common mistake that many users, and even some companies, have with overhead cables. In order to save money and regardless of safety, some users choose those low-quality overhead cables with low price, unsecured quality, and large accidents. We know that due to factors such as safety wires and cables, the price of overhead cables cannot meet some of the requirements of users. Some private enterprises fail to meet the national standards for manufacturing overhead cables in terms of material selection, production technology, and testing methods, and their safety cannot be guaranteed. So please don't covet cheap overhead cable users.
Some users lack understanding of their electrical requirements, environmental conditions, wire and cable models, requirements, performance, etc., and often choose the wrong model. For example: a blast furnace slag transporter in a steel plant is powered by an electric motor, and the furnace temperature is as high as 800℃~900℃. Under such environmental conditions, since the special requirements for the overhead cables in the plant are unknown, the choice is generally to use rubber sleeves to fill YC type, as a result, the use time is short, and the sheath is scorched, which not only affects the production, but also wastes the economy. After negotiation, choose flame-retardant cables, replace cables to reduce pain and economic losses, and ensure normal production. Some important departments, high-rise buildings, computer centers, chemical industries, public entertainment places and other places where people are concentrated should use cables with flame retardant or fire resistance; Cables, electrical wiring, etc., have special performance requirements. These special wires and cables have special requirements in actual use. Many companies, especially individual companies, often lack knowledge and refuse to use them; some companies ignore the regulations of the Ministry of Coal Mines, and cables used in deep coal mines must have flame retardant requirements, but later Soft tire cables are usually used; there are also some karaoke halls, where some general personnel focus on the installation of overhead cables that do not have fire protection functions, causing serious accidents.
