Abstract
The utility model relates to an anti-snow anti-freezing environmental-friendly overhead cable, which belongs to the technical field of cables, and comprises a sheath and an electrical cable core which is formed by a reinforced core, a conductor and an insulating layer in the sheath. The utility model is characterized in that the anti-snow anti-freezing environmental-friendly overhead cable is provided with the heating element which is formed by four PTC materials with positive temperature coefficients the aluminum alloy electrode, wherein the heating element is wound on the periphery of the electric cable core in the sheath in the same spacing, and the sheath on the heating element is outwards raised. The utility model has the advantages of reasonable and simple structure, simple production and manufacture, low production cost and excellent electric performance, physical property and chemical stability. The anti-snow anti-freezing environmental-friendly overhead cable adopts the reinforced core, which improves the intensity of cables, and has big bearing capacity. The sheath on the heating element is outwards raised, which has the self-snow-removing property. A warming-up system can be started to melt ice and snow through the heating element in snow disasters and freezing, and the danger of service interruption caused by snow freezing can be greatly reduced.
Description
Technical field
The utility model relates to a kind of structure of snow-proof freezing resistant environment protection aerial cable, and certain construction of cable that removes to avenge and have heating system is certainly particularly arranged, and belongs to the cable technology field.
Background technology
2008 around the Spring Festival, and various places, China south suffer the especially big snow disaster of not meeting in 50 years, and electrician's facilities such as province's transmission line such as Hunan, Hubei, Sichuan, Shaanxi, Gansu, Qinghai, Henan, Shanxi, Anhui, Jiangsu are badly damaged.It is even more serious to suffer from disaster to Hunan Nanjing University, accumulated snow, sleet crushed power transmission and transformation line and towering iron tower, and only following defeated, the distribution line of more than 1000 500KV in Hunan Province stops normal operation, involves part, and the people produce, the life order is had a strong impact on.South wintry weather humidity usually descend rain and snow mixed, than fearful freezing in addition of rain and snow mixed, rain, avenge and freezes while falling, and can be attached on conductive line surfaces immediately, forms more and more thicker hard ice slush, and is difficult for rooting out.Common transmission pressure does not have to clear up the function of hard ice slush automatically, in case run into the tragedy that the low temperature sleety weather can only face broken string.
The utility model content
The purpose of this utility model is exactly at existing transmission pressure above shortcomings, and a kind of certain snow-proof freezing resistant that removes to avenge and have heating system certainly that both had is provided, and the aerial cable of good electric property, physical property, chemical stability is arranged again.
The purpose of this utility model is to realize like this, the snow-proof freezing resistant environment protection aerial cable, comprise the electric cable core that constitutes by strengthening core, conductor, insulating barrier in sheath and the sheath, it is characterized in that being provided with four and have the ptc material of positive temperature coefficient and the heating element that aluminum alloy anode constitutes, the periphery of the electric cable core of pitches such as heating element in the sheath, the sheath at heating element place is to outer lug.
Described strengthening core is high-strength galvanized steel wire or carbon steel wire.Conductor is an aluminium alloy conductor.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and good electric property, physical property and chemical stability are arranged, and has from going the snow and the snow-proof freezing resistant performance of heating.Strengthening core adopts zinc-coated wire, the cable that long distance is laid adopts high-carbon steel wire, diameter is thick, intensity is high, bearing capacity is big, high-carbon steel wire tensile strength 〉=1300Mpa, the employing mild steel wire is set up in short distance, diameter is little, intensity is low, bearing capacity is less demanding, flexible, mild steel wire tensile strength 〉=900Mpa, blemish such as zinc-coated wire any surface finish, no water stain, dezincify, ring shape.Conductor adopts the aluminum alloy materials of good conductivity, adopts strands.The insulation cross-linking polyethylene materials.Heating element adopts ptc material and aluminum alloy anode with positive temperature coefficient to constitute.The protection sheath adopts the weather resistant polyolefine material.The heating element that ptc material and aluminum alloy anode constitute is set in the periphery of electric cable core, sheath; the sheath at heating element place has from going to avenge performance to outer lug, meets snow disaster and freezing; can start heating system and thaw ice and snow, reach the protection cable by heating element.The cold that is laid in or be prone to freezing zone can significantly reduce because of snow and freeze the danger that has a power failure.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 strengthening core, 2 conductors, 3 insulating barriers, 4 heating elements, 5 sheaths.
Embodiment
The snow-proof freezing resistant environment protection aerial cable: strengthening core 1 is arranged in the middle of the conductor 2, and conductor 2 is stranded with strengthening core 1.Strengthening core 1 adopts the stranded composition of zinc-coated wire.Conductor 2 adopts the aluminum alloy materials of good conductivity, and conductor adopts strands.Outside conductor, extrude cross linked insulation layer 3 and constitute electric cable core.Equal angles is placed four heating elements 4 that are made of ptc material that positive temperature coefficient is arranged and aluminum alloy anode in insulating barrier 3 and sheath 5, and pitches such as heating element 4 are around the periphery of electric cable core.Sheath 5 adopts the weather resistant polyolefine material to be extruded in the periphery of electric cable core and heating element, and the sheath at heating element place is to outer lug.
Claims (3)
1, a kind of snow-proof freezing resistant environment protection aerial cable, comprise the electric cable core that constitutes by strengthening core, conductor, insulating barrier in sheath and the sheath, it is characterized in that being provided with four and have the ptc material of positive temperature coefficient and the heating element that aluminum alloy anode constitutes, the periphery of the electric cable core of pitches such as heating element in the sheath, the sheath at heating element place is to outer lug.
2, snow-proof freezing resistant environment protection aerial cable according to claim 1 is characterized in that described strengthening core is high-strength galvanized steel wire or carbon steel wire.
