Abstract
The utility model discloses a high-temperature-resistant cable, which comprises an ordinary cable; wherein, the outer surface of the ordinary cable is wrapped by a blowing layer; and the surface of the blowing layer is provided with air holes which are communicated with an air channel in the blowing layer. Since the blowing layer provided with the air holes is arranged outside the ordinary cable, the heat of the surface of the cable can be blown away through the air channel in the blowing layer, so that the temperature of the cable can be reduced, consequently, the use temperature of the cable can be increased, the current-carrying capacity of the cable can be enhanced, and the use safety of the cable can be ensured.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of anti-high-temperature cable.
Background technology
Cable is when electric energy transmitting, because of conductor heating causes temperature rise, even continuous rising that can Yin Wendu and cause burning fire calamity hidden danger.At present common cable is because of being subjected to the restriction of macromolecular material temperature resistant grade, and the cable surface heat radiation is slower, and the cable surface heat can't in time leave, thereby limits and influence the ability of cable transmission electric energy, has limited the ampacity of cable.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, provides a kind of and can in time take away the cable surface heat, avoids fire, improves the anti-high-temperature cable of electric energy transmitting ability.
Technical scheme: anti-high-temperature cable described in the utility model, comprise common cable, it is characterized in that being coated with one deck air blast layer at the outer surface of common cable, the surface of air blast layer be provided with the air blast layer in the pore of air flue UNICOM.
Operation principle: core of the present utility model is the air blast layer that is provided with the band pore outside common cable, takes away the heat of cable surface by the air blast of air flue in the air blast layer, reduces cable temperature, thereby can improve the serviceability temperature of cable, increases the cable current capacity.
Beneficial effect: the utility model can improve the ability of cable transmission electric energy effectively, increases the ampacity of cable, guarantees the fail safe that cable uses.
Description of drawings
Accompanying drawing is a cross section structure schematic diagram of the present utility model.
Embodiment
Anti-high-temperature cable as shown in the figure comprises common cable 1, establishes the air blast layer 2 of one deck band pore 3 in the appearance of common cable 1.Air blast layer 2 is a hollow layer, and its superficies are provided with continuously pore 3 uniformly, by this pore the heat in the air blast layer are taken away.
Claims (3)
1, a kind of anti-high-temperature cable comprises common cable (1), it is characterized in that being coated with one deck air blast layer (2) at the outer surface of common cable (1), the surface of air blast layer (2) be provided with the air blast layer in the pore (3) of air flue UNICOM.
2, anti-high-temperature cable according to claim 1 is characterized in that air blast layer (2) is a hollow structure.
3, anti-high-temperature cable according to claim 1 and 2 is characterized in that being provided with pore (3) continuously equably on the surface of air blast layer (2).
