Abstract
The utility model discloses a moisture -proof overhead insulated cable, the control cable comprises insulated wire cores, insulation core by two aluminum alloy conductor that parallel, be located copper conductor and the irregularly shaped common insulating layer of crowded package outside four conductors that aluminum alloy conductor parallels from top to bottom and constitute, fill the yarn that blocks water outside insulation core, is crowded package thickness 2.55 outside the yarn that blocks water 2.75mm the dampproof course, the dampproof course is equipped with 1.5 outward 3cm's metal tensile pipe. The utility model has the advantages of good, the difficult disconnected core of aging resistance, dampproofing and waterproofing nature, bearing nature is strong, the mechanicalness good, the pull resistance is good.
Description
Technical field
This utility model is related to power cable field, refers in particular to a kind of 10kv damp-proof aerial insulated cable.
Background technology
At present, with social development, the demand of cable rises steadily, people's also more and more higher of the requirement to cable,
Especially in the environment of aerial cable, when cable is subject to external stress to act on, its internal wire is susceptible to displacement, leads to
Cable local temperature is too high, the communication efficiency of impact cable；Existing cable water-blocking moistureproof effect is poor, in cable work process
In, run into rainwater weather and easily intake, cause its current-carrying capacity to reduce.
In addition, built on stilts span is restricted, and built on stilts yardstick is big, not only causes cost to raise, and resist external wind with
And the ability of rainy day is poor, if running into thunderstorm gale weather, and hail frost, it is susceptible to rupture and cause accident.Cause
This, provide that a kind of to have waterproof and dampproof aerial cable be those skilled in the art's urgent problem.
Utility model content
Technical problem to be solved in the utility model there is provided that a kind of waterproof and dampproof property is good, mechanicalness is good, load
The good, aerial insulated cable of not easily broken core.
A kind of damp-proof aerial insulated cable described in the utility model, including cable core, including insulated wire cores, described is exhausted
Edge core by two aluminium alloy conductors arranged side by side, be located at aluminium alloy conductor copper conductor arranged side by side up and down and be extruded in four conductors
Outer erose common insulating barrier is constituted；Fill water blocking yarn outside insulated wire cores, extruding thickness outside water blocking yarn is
The damp-proof layer of 2.55-2.75mm, damp-proof layer is externally provided with the metal anti-stretching pipe of 1.5-3cm.
Improve further, in described aluminium alloy conductor, be provided with carrying core.
Improve further, described carrying core is steel wire rope.
The beneficial effects of the utility model are:
1st, adopt aluminium alloy conductor, increase tensile strength, enhance pulling force.
2nd, be provided with aluminium alloy conductor carrying core so that cable is in thunderstorm gale weather, and hail frost it is not easy to
Fracture is occurred to cause accident.
3rd, filling adopts water blocking yarn, prevents water inlet in conductor from leading to the damage of cable.
4th, this utility model changes original aerial cable structure, is directly provided with metal anti-stretching pipe in cable outermost layer,
Make the compressive property of cable good, moistureproof and good airproof performance, embossing can improve its bending property.
5th, this utility model cable core adopts multicore composite construction, and multiple conductors are used in conjunction with an insulating barrier, change former
Some structures, so that the insulating properties of cable also improve a lot, also save material and cost.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, a kind of damp-proof aerial insulated cable described in the utility model, including insulated wire cores, described
Insulated wire cores by two aluminium alloy conductors 2 arranged side by side, be located at aluminium alloy conductor copper conductor 3 arranged side by side up and down and be extruded in four
The common insulating barrier 4 of the irregular flower-shape outside conductor is constituted；Fill water blocking yarn 5 outside insulated wire cores, outside water blocking yarn 5, extrude thickness
Spend the damp-proof layer 6 for 2.55-2.75mm, damp-proof layer is externally provided with the metal anti-stretching pipe 7 of 1.5-3cm, this pipe compressive property is good, moistureproof
And good airproof performance, embossing can improve its bending property.
So that cable is in thunderstorm gale weather, and it is not easy to there is fracture and causing accident in hail frost, described
Aluminium alloy conductor in be provided with carrying core 8, this carry core be steel wire rope.
This utility model provides a kind of thinking of damp-proof aerial insulated cable and method, implements this technical scheme
Method and approach a lot, the above is only preferred implementation of the present utility model it is noted that for the art
Those of ordinary skill for, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, this
A little improvements and modifications also should be regarded as protection domain of the present utility model.In the present embodiment, clearly not each component part is all available existing
Technology is had to be realized.
