Description
Technical field
Electric wire field is the utility model is related to, specifically a kind of reinforced aluminium alloy core crosslinked polyethylene insulated aerial
Coaxial cable.
Background technology
The selection of the span of aerial insulated cable directly influences the construction costs of power transmission sequence and safe for operation, and engineering is made
Valency and the problem of being currently in mutual restriction safe for operation, though aerial insulated cable cable has been widely used, span length is short,
The problems such as security is not high, construction costs just becomes increasingly conspicuous in the recent period, and causes power department to be paid much attention to.
There has been aerial insulated cable national standard the country, and simply fine aluminium core overhead insulated cable is defined in the standard
Structure type and technical requirements, fine aluminium core overhead insulated cable much can not meet the laying requirement of large span, run into rivers resistance
Every or be not easy short distance set span points situation when, the cable laying also have peripheral hardware steel strand wires with support the intensity of cable will
Ask, using the form, construction costs will significantly improve, and wire clamp and aerial insulated cable have certain friction, direct shadow
Ring the safe operation of the service life and circuit to cable.It will necessarily be replaced using reinforced large span aerial insulated cable as it
For product, reinforced large span aerial insulated cable can also increase span points in conventional project, reduce construction costs.
Utility model content
The purpose of this utility model is for overcome the deficiencies in the prior art, there is provided one kind is with unit weight is light, intensity is high, exhausted
Heat, sound insulation, fire-retardant, cold-resistant, anti-corrosion, do not absorb water, the reinforced aluminium alloy core crosslinked polyethylene insulated aerial of simple and quick construction
Coaxial cable.
A kind of reinforced aluminium alloy core crosslinked polyethylene insulated aerial coaxial cable described in the utility model, including set
The reinforcement steel core of the heart in the cable, the six roots of sensation is externally provided with to strengthen steel core as the axisymmetric aluminium alloy conductor in axle center strengthening steel core,
The fire-retardant composite band that blocks water is filled with strengthening the gap of steel core in six roots of sensation aluminium alloy core, fire-retardant composite band peripheral hardware is crosslinking blocking water
Polyethylene layer；There is hollow bundle line aluminum pipe in crosslinked polyetylene insulated layer overcoat, it is compound to be externally provided with polyurethane in bundle line aluminum pipe
Insulating tube；Ten six roots of sensation are provided with described hollow bundle line aluminum pipe to strengthen steel core as the axisymmetric aluminium conductor in axle center.
Further improve, described strengthen the ratio between steel core, aluminium alloy core and cross section of aluminium core three are 1.5:1:1.
Further improve, the described fire-retardant composite band that blocks water without anti-strap and alkali-free glass fibre band by being twisted.
Further improve, the cross section of described reinforcement steel core is 2-2.5mm2.
Compared with prior art, the utility model has the advantage of：
1st, there is a center carrying steel core using the inner conductor center of cable, the stress point of inner wire concentrates on center and held
Carry on core, cable protects inner wire annealing copper wire, and be not easily broken in folding and unfolding winding process；Simultaneously external conductor by
Aluminium conductor, aluminium conductor annealing aluminium wire gap are entwined, and in carrying, cable outer conductor each several part not only uniform force, are also carried
The high tensile property of inner wire annealed Al-alloy silk.
2nd, insulating barrier uses crosslinked polyethylene material, and its dielectric strength is high, and anti-aging, resistance to brittleness can be good, and weatherability is old
Change；
3rd, the fire-retardant composite band that blocks water is filled so that cable both can be with fire-proof function or with water-proof function.
4th, when outer conductor is grounded, external electric field does not interfere with inside, and internal electric field does not interfere with outside yet, so coaxial electrical
Cable outer conductor ground connection has the benefit that shielding internal/external signal interferes with each other, and can improve signal quality, and improve signal transmission rate.
5th, using polyurethane composite thermal insulation pipe so that there is cable intensity height, impact resistance, the prestressing force of resistance to environmental aging to split
Open, be corrosion-resistant, be low temperature resistant, easy welding, easy construction, strictly seal ne-leakage, also with unit weight is light, intensity is high, it is adiabatic, every
Sound, fire-retardant, cold-resistant, anti-corrosion, do not absorb water, the excellent characteristics such as simple and quick construction, adaptive temperature is+120 DEG C--196 DEG C so that
Cable, because icing causes communication signal transmissions to interrupt, causes the economic loss that can not be saved in ice and snow weather.
