By examining the processes the defects in time.
attachment cable fire prevention measures of the three: must be selected to meet thermal stability condition of the cable. Choose the cable in the case of normal, need to meet the rated load over a long period of heating requirements; In the case of short circuit, but also to meet the short-term heat stability, try to avoid overheating cable resulting in a fire.
attachment cable fire prevention measures of the four: very important point. Staff need to periodically to repair and test of cable, according to the regulation and the actual situation of cable operation, repair and test of cable should be periodically, so that we can discover the latent fault and deal with the defects, guarantee the safe operation and avoid the cable fire.

Between cable laying, cable, cable and power between the pipe and other pipe, cable and roads, railways, buildings etc. The distance between parallel or cross shall meet the provisions of the regulations.
