The problem of, it is cable market urgent problem to be solved instantly.
Currently, in the market application No. is 200720018511.1 Chinese patents to disclose a kind of heat dissipation electric wire cable,
It includes leading core, insulating layer, sheath, and ridge design is equipped in the outer circle of sheath.Although this heat dissipation electric wire cable can rise
To the effect of heat dissipation, but only increase the heat dissipation area of wire and cable in the outer circle of sheath, what a kind of such way played
Heat dissipation effect is not that very well, can not completely be vaporized away the hot gas in wire and cable.
In addition in the market application No. is 201220356993.2 Chinese patent disclose it is a kind of can heat dissipation hollow electricity
Cable, it include hollow electric conductor, the insulating layer being wrapped in outside hollow electric conductor, positioned at hollow electric conductor both ends with it is hollow
Two connecting terminals that electric conductor is fixedly connected, above-mentioned each connecting terminal has to be connected with the hollow cavity of hollow electric conductor
Logical heat release hole, although it has heat release hole, internal heat dissipation performance is simultaneously bad, and is provided with heat release hole in outside, interior
Any water-tight device does not do again in portion, although playing the effect of heat dissipation in this way, when moist ground is arranged in this cable
When square, the heat of generation, it is easy to make the moisture in air become droplet, cable is caused to be intake, it may occur that accident.
