Description
Technical field
The utility model belongs to power cable technical field, relates to a kind of Novel heating cable.
Background technology
Along with China's economic growth continuously and healthily, the continuous expansion of China electric power industry, data communication industry, urban track traffic industry, car industry and shipping industry scale, the demand of China to electric wire also increases rapidly, and following electric wire industry also has huge development potentiality.But the operational environment of cable is changeable, cable, once be destroyed, can cause serious economic loss immediately, makes troubles to our production and life.Only for power industry, when extremely frigid zones meets wind and snow, sleet, often there is removing ice from cable phenomenon in cable, cause down bar, fall the accidents such as base, steel tower cave in, broken string, cannot normal power supply, even cause large-area power-cuts, power grid operation is caused to having a strong impact on.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of Stability Analysis of Structures, and intensity is higher and have the Novel heating cable of intensification heating function.
The purpose of this utility model realizes by following technical proposal: a kind of Novel heating cable, it is characterized in that: comprise the oversheath that ecto-entad sets gradually, armour and inner covering, some wires are enclosed with in described inner covering, described wire comprises insulating barrier and is located at the conductor in insulating barrier, center strengthening core is provided with between some described wires, described strengthening core is provided with arc groove that is identical with number of conductors and that arrange along cable length direction, described wire leans with groove cell wall and inner covering respectively, and adjacent two wires lean, and adjacent against two be provided with some linings between wire and inner covering, described some linings are along cable length directional spreding, and lining is embedded with heater wire.
Because strengthening core is provided with arc groove that is identical with number of conductors and that arrange along cable length direction, and wire leans with groove cell wall and inner covering respectively, therefore strengthening core not only increases bulk strength, and serve the effect of stabilizing lead, prevent wire distortion from fractureing or misplacing and cause each section of intensity to differ, and adjacent against two linings be provided with between wire and inner covering be embedded with heater wire, the temperature of whole section of cable can be heated by heater wire, prevent cable surface accumulated snow from causing cable breakdown.
In above-mentioned Novel heating cable, described wire and heater wire quantity are four, and adjacent against two some linings between wire and inner covering in be embedded with a heater wire.
Therefore overall structure is comparatively stable.
In above-mentioned Novel heating cable, described insulating barrier is foam crosslinked polyethylene, and described oversheath is that acrylonitrile-butadiene rubber is made.
In above-mentioned Novel heating cable, described armour is steel wire armor layer or steel-tape armouring layer.
Not only intensity is higher to arrange armour, and plays the effect of shield electromagnetic interference.
In above-mentioned Novel heating cable, described inner covering internal pore place is provided with packed layer.
Compared with prior art, the utility model tool has the following advantages:
Because strengthening core is provided with arc groove that is identical with number of conductors and that arrange along cable length direction, and wire leans with groove cell wall and inner covering respectively, therefore strengthening core not only increases bulk strength, and serve the effect of stabilizing lead, prevent wire distortion from fractureing or misplacing and cause each section of intensity to differ, and adjacent against two linings be provided with between wire and inner covering be embedded with heater wire, the temperature of whole section of cable can be heated by heater wire, prevent cable surface accumulated snow from causing cable breakdown.
Accompanying drawing explanation
Fig. 1 is cross section view of the present utility model;
