Power cables are cable products used in the trunk lines of power systems to transmit and distribute high power electrical energy, including various voltage classes, 1-500KV and above, and various insulated power cables. The wire and cable industry is the second industry in China next to the automobile industry, and both the product variety satisfaction rate and the domestic market share rate exceed 90%. The total output value of the electric wire and the electric cable in China exceeds the United states worldwide, and the electric wire and the electric cable become the first country for producing the electric wire and the electric cable in the world. Along with the high-speed development of the China wire and cable industry, the number of newly added enterprises is continuously increased, and the overall technical level of the industry is greatly improved.

For this reason, attention should be paid to the fire protection of the power cable. The reason that the cable fires and explodes is still related to insulation, a large amount of heat can be generated when the cable runs under overload for a long time, the heat enables the insulating glue to age and burst, and then insulation breakdown is caused, so that the cable fires and explodes.
The main measure for preventing the cable explosion is to sleeve the explosion-proof box at the intermediate joint of the cable, but the structural strength of the current explosion-proof box is not enough, when the box body is burst by the expansion of the insulating glue, the explosion-proof box can not play the role of preventing water vapor from entering, and can not play the role of early warning before the explosion, so that the operation of the cable line can not obtain higher safety guarantee.
