Description
Technical field
It the utility model is related to field of cables, and in particular to a kind of anti-extrusion aerial 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.
At present, the dowel of aerial cable is all to only serve connection function so that the structure of cable is fixed, without bullet
Property, it is impossible to it is flexible, it is harder, be squeezed will easily be compressed it is bad so that the service life of cable is short, and cost is high.
Utility model content
Purpose of utility model：In order to overcome the deficiencies in the prior art, there is provided it is a kind of simple in construction, flexible,
Changeability, superpower anti-extrusion aerial cable.
Technical scheme：To achieve the above object, the utility model provides a kind of anti-extrusion aerial cable, including connection branch
Frame, three skies that described connecting bracket includes the solid reinforcing bar of one, center triangle and the solid side of reinforcing bar three of triangle stretches out
The heart connects pillar, and the solid reinforcing bar of described triangle and three hollow connection pillars are integral type structure；In three hollow connection branch
Three insulated wire cores are connected on post respectively, three insulated wire cores are provided with arc elastic and strengthen firm dowel between each other two-by-two；
The connecting bracket, two insulated wires of two insulated wire cores and connection with any two hollow connection pillars in connecting bracket
The arc elastic of core strengthens the gap filling support block of firm dowel composition；Described support block is irregular structure,
Top is " V " shape structure, is provided with two straight flanges along " V " shape mouth or so, bottom is an outer arcuate side, and both sides are arc side.
Further, the polyethylene that described insulated wire cores are extruded in by aluminium alloy conductor, successively outside aluminium alloy conductor is exhausted
Edge layer and copper sheath are formed.
Further, it is provided with spring in the hollow connection pillar.
Further, described support block is polyvinyl chloride support block.
Compared with prior art, the beneficial effects of the utility model are：
1st, provided with triangle stiffener, compared to existing circular configuration so that the construction of cable is more firm, and is adding
Spring dowel is designed with outside strong steel core, instead of dowel of the prior art, changes the problem of original non-stretchable,
So that cable is flexible, there is retractility when being squeezed；Also become in an installation in addition more flexibly, to installation
Bring conveniently.
3rd, it is provided with arc elastic between each other two-by-two in insulated wire cores and strengthens firm dowel, the dowel is that one kind can bullet
Property flexible plastic, adds steel core so that cable integral support structure is consolidated, and flexible, is matched somebody with somebody in plastics
Spring is closed, strengthening firm dowel with telescopic spring arc elastic can inwardly be bent outwardly so that cable overall structure is more
Add flexible, changeability.
4th, insulated wire cores outer layer is steel sheath so that it is more convenient to be connected with every kind of reinforcement, in welding process more
Agree with, more firmly.
5th, in order to further strengthen the anti-extrusion of cable, any two hollow companies in connecting bracket and connecting bracket
The arc elastic for connecing two insulated wire cores of two insulated wire cores and connection of pillar strengthens the space part of firm dowel composition
Divide filling support block, along with gusseted so that anti-extrusion of the anti-extrusion of cable than prior art is higher by hundred times, makes
Outer bound pair its intensity extruded will greatly reinforce, in general pressure, to the extruding force of this cable equivalent to for zero.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of support block.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
