Abstract
本实用新型涉及一种集束架空绝缘电缆，包括至少两根相线芯导体、包裹在相线芯导体外侧的绝缘层，包裹有绝缘层的各相线芯之间通过绝缘连接筋连接，绝缘连接筋与相邻的绝缘层之间为一体结构，其特征在于：所述各相线芯导体之间呈平行状排列，绝缘连接筋的厚度大于绝缘层的厚度。因此本实用新型采用上述结构可模具一次挤出成型，各相线芯位置固定，不存在散股现。各相线芯之间平行，利用绝缘层将其连接在一起，所以不会相互接触造成短路，而且生产工艺简单、防止相间短路，使用寿命长等优点。
The utility model relates to a bundled overhead insulated cable, which comprises at least two phase core conductors and an insulating layer wrapped on the outside of the phase core conductors, and the phase cores wrapped with the insulating layer are connected by insulating connecting ribs, and the insulating connection The ribs and adjacent insulating layers are integrally structured, and the feature is that: the conductors of the phase cores are arranged in parallel, and the thickness of the insulating connecting ribs is greater than that of the insulating layer. Therefore, the utility model adopts the above-mentioned structure, which can be extruded and molded at one time, and the positions of the wire cores of each phase are fixed, and there is no loose strands. The cores of each phase are parallel to each other, and they are connected together by an insulating layer, so there is no short circuit caused by mutual contact, and the production process is simple, preventing short circuit between phases, and long service life.
Description
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.
