Abstract
The invention discloses a flexible cable for power-on deicing. The flexible cable for power-on deicing comprises power-on heating cable cores, a main power cable core, a metal shielding layer, a ceramic fiber strip and a polyolefin insulating layer. Each power-on heating cable core is formed in the mode that a flame-retardant knitting taped covering layer is wrapped on heating conductors, wherein a heat conduction filling layer is arranged between the flame-retardant knitting taped covering layer and the heating conductors of each power-on heating cable core. The main power cable core is formed in the mode that a silicone rubber insulating layer is wrapped on tinned copper core conductors. The power-on heating cable cores are arranged outside the main power cable core. The metal shielding layer is wrapped on the power-on heating cable cores to form a cable core assembly, an anti-freezing filling layer is arranged in a gap in the cable core assembly, and the cable core assembly is covered with the ceramic fiber strip and the polyolefin insulating layer in sequence from inside to outside. The flexible cable for power-on deicing is stable in performance and can be heated after being powered on, the problems that the surfaces of cables ice up in cold weather and the cables need to be deiced are solved, and the cable is flexible, good in shielding performance and resistant to cold and freeze.
Description
technical field
The present invention relates to cable, relate in particular to a kind of energising deicing flexible cable.
Background technology
At present, the place operation such as outdoor, outdoor during to winter in the north, cable can freeze, and more knot is more, more knot is thicker, at this moment just need to carry out artificial deicing, if ice can not be removed in time, too large to the heavy burden of cable, can cause pylon, line bar to collapse, the power outages such as transmission line short circuit, severe one can cause loss of life or personal injury, thereby need to adopt and a kind ofly can play the cable of ice-melt effect once switching on, solve current cable ice formation issues, have very important significance.
Summary of the invention
For addressing the above problem, the object of the invention is to provide a kind of energising deicing flexible cable.
The solution of the present invention is as follows: a kind of energising deicing flexible cable, comprise energising heating core, active force core, metal screen layer, ceramic fibre strip and polyolefin insulation layer, described energising heating core is to form on heater by fire-retardant braiding lapping layer is wrapped, between fire-retardant braiding lapping layer and heater, is provided with heat conduction packed layer; Described active force core is to extrude tin-coated copper core conductor by silicone rubber insulation layer to form; Described energising heating core is arranged on outside active force core; It is cable core that described metal screen layer extrudes several energising heating cores; In gap in described cable core, be provided with antifreeze packed layer; Described ceramic fibre strip and polyolefin insulation layer from inside to outside cover on cable core successively.
The quantity of described energising heating core is 3-8 group.
Beneficial effect of the present invention: stable performance of the present invention, energising can be to electric cable heating, solves the cold snap cable surface problem of thawing of freezing, and cable softness, advantages of good shielding performance, cold-resistant antifreeze.
