Abstract

The utility model relates to a tensile copper -clad aluminum core aerial cable, including conductor unit and strengthening rib unit, the conductor unit includes two at least core units and protective sheath, the core unit includes two piece at least conductor silks, first filling layer and insulating layer the cladding has a second filling layer on two at least core units the cladding of second filling layer surface has the second protective layer, the both ends symmetry is equipped with strengthen unit about the conductor unit outside, strengthen unit includes four piece at least regular polygon steel wires, the mutual in close contact with of regular polygon steel wire, the conductor unit with strengthen unit outside cladding has the fourth filling layer. The utility model discloses an increase strengthen unit, and the strengthening rib unit uses regular polygon's steel wire to carry out in close contact with, the ordinary circular steel wire of comparing has held more steel wires on the basis of the same cross section, solved the problem that cable intensity in the use is not enough, the rigidity is not enough, and life increases.

Description

A kind of copper-covered aluminum-core tension aerial cable

Technical field

This utility model belongs to field of cables, is specifically related to a kind of copper-covered aluminum-core tension aerial cable.

Background technology

Existing insulated aerial cable is made up of single or multicore, and this cable has good transmission performance, but when transmitting electricity at a distance, intensity and the rigidity of cable are inadequate, it is easy to the deformation stayed, and have transmission of electricity potential safety hazard.

Utility model content

For above-mentioned problem of the prior art and non-foot point, this utility model provides a kind of copper-covered aluminum-core tension aerial cable, has good tensile property, long service life, transmission of electricity safer.

For solving the problems referred to above, adopted the technical scheme that:

A kind of copper-covered aluminum-core tension aerial cable; including conductor element and rebar element; described conductor element includes at least two core unit and protection set; described core unit includes at least two conductor silks, the first packed layer and insulating barrier; described conductor silk is twisted together; described conductor silk includes aluminum core and is coated on the layers of copper on described aluminum core, is coated with the second packed layer, is coated with the second protective layer at described second packed layer outer surface on described at least two core unit；Outside described conductor element, two ends, left and right are arranged with reinforcement unit; described reinforcement unit includes at least four regular polygon steel wires; described regular polygon steel wire is closely contacted with each other, and is coated with the 3rd packed layer at described regular polygon steel wire, and described 3rd packed layer is coated with the 3rd protective layer；Outside described conductor element and described reinforcement unit, it is coated with the 4th packed layer, outside described 4th packed layer, is coated with the 4th protective layer.

Preferably, described regular polygon steel wire is diamond wire.

Preferably, the material of described first packed layer is glass cord.

Preferably, the material of described insulating barrier is polrvinyl chloride.

Preferably, described 4th protective layer is Muscovitum belt.

Adopt technique scheme, acquired provide the benefit that:

A kind of copper-covered aluminum-core tension aerial cable in this utility model, by increasing reinforcement unit, and rebar element uses the steel wire of regular polygon to be in close contact, compare common round wire, the basis of identical cross-section contains more steel wires, the problem solving cable in use insufficient strength, rigidity deficiency, service life increases.
