Wire and power cable use errors

This is a considerable number of users, and even some companies use overhead cable presence of the more common errors. Some users save money, ignore safety, specifically pick those low prices, quality is not guaranteed, accidents big inferior overhead cable. We know that because of safety wire cable and other factors, resulting in overhead cable prices can not meet some of the requirements of users. Some private enterprises in terms of material selection, production technology, detection means and so are unable to meet the national standard manufacture of overhead cable, and its security will not be guaranteed, plus a fuss over a short foot less rice, with its low price flooding the market to cater to some users. So please do not covet cheap users of overhead cable.

Some users of their electrical requirements, environmental conditions, lack of knowledge on the use of wire and cable models, requirements, performance, poorly understood and often choose the wrong model. For example, a steel mill blast furnace slag transport vehicle, its power is a motor, furnace temperatures up to 800 ℃ ~ 900 ℃, under such environmental conditions, because the plant overhead cable has what the Special Request no knowledge, then the choice of general use rubber sheathed cable filling YC type, the results using a short time, the jacket was scorched, only affects the production, but also a waste of the economy. After consultation, the choice of fire retardant cable, and replacement of the cable reduces the pain and economic loss to ensure normal production. 

Some important sectors, high-rise buildings, computer centers, chemical, public entertainment, and officers to concentrate on other occasions, are to be used with a fire retardant or fire resistant cables function; Coal Ministry of cables used in deep coal mines must have a flame retardant; There are elevator cables, welding cables, electrical wiring, etc. Have special performance requirements. 

These specialty wires and cables have special requirements in actual use, the number of enterprises, especially individual enterprises tend to lack knowledge, and refused to use them; some companies ignore the provisions of the Ministry of Coal cables used in deep coal mines must have a flame retardant requirements, but later Usually capture cable; there is some karaoke OK hall, some general officers to concentrate on the occasion of overhead cable installation does not have fire protection function, causing great accidents.
