Abstract

The utility model relates to a bundle assembled aerial insulation cable, which comprises at least two phase line core conductors and insulation layers, wherein the insulation layers are covered outside the phase line core conductors, each phase line core covered with the insulation layers is connected through insulation connecting ribs, and the insulation connecting ribs and adjacent insulation layers are in an integral structure. The utility model is characterized in that each phase line core conductor is in parallel arrangement, and the thickness of the insulation connecting ribs is greater than the thickness of the insulation layers. Thereby, the utility model can realize one-step extrusion molding by adopting the structure, the position of each phase line core is fixed, and the broken lot phenomenon does not exist. All phase line cores are parallel to each other, and are connected together through the insulation layers, so the short circuit caused by mutual contact can not occur, and in addition, the utility model has the advantages of simple production process, interphase short circuit prevention, long service life and the like.

Description

Bunched aerial insulated cable

Technical field

The utility model belongs to the aerial cable technical field, particularly relates to a kind of bunched aerial insulated cable.

Background technology

At present, known aerial cable, all employing lay configuration that two cores are above.Phase line core conductor skin is enclosed with insulating barrier, then multiply insulated phase wires core is twisted together the formation product.Common multicore aerial insulated cable complex process; Be in contact with one another between the phase core, long-time running very easily causes short circuit phenomenon; Laying tension was inhomogeneous when core was stranded, was subjected to wind-force and other factor affecting the broken lot phenomenon can occur for a long time, also can the phase mutual friction between each core, and the damage insulating barrier.

Summary of the invention

The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, production technology simple, prevent phase fault, the bunched aerial insulated cable of long service life.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of bunched aerial insulated cable, comprise at least two phase line core conductors, be wrapped in the insulating barrier in the phase line core conductor outside, be enclosed with between each phase core of insulating barrier and connect by the insulation dowel, be structure as a whole between insulation dowel and the adjacent insulating barrier, it is characterized in that: be parallel shape between described each phase line core conductor and arrange, the thickness of insulation dowel is greater than the thickness of insulating barrier.

The utility model can also adopt following technical measures:

Solid conductor or stranded conductor are adopted in the cross section of described phase line core conductor.

Advantage and the good effect that the utlity model has are: because the utility model technique scheme is compared with existing aerial cable, have the following advantages: 1, product is by an extrusion molding of mould, and each phase core fixed-site does not exist broken lot existing.2, parallel between each phase core of this product, utilize insulating barrier to connect together, do not cause short circuit so can not be in contact with one another, and have production technology simple, prevent advantages such as phase fault, long service life.
