Abstract
The invention provides a 0.6/1kv power cable. The 0.6/1kv power cable comprises three groups of main cable cores and one group of secondary cable fore, wherein the main cable cores and the secondary cable fore are covered by an inner protection sleeve layer 4; a steel wire armor layer 5 is arranged outside the inner protection sleeve layer 4; an outer protection sleeve layer 6 is arranged outside the steel wire armor layer 5; a filling layer 3 is arranged into a gap between the cable cores; each of the main cable cores is formed by extruding and covering a main insulating layer 2 by main conductors 1 with sector-shaped sections; the secondary cable core is formed by extruding and covering a second insulating layer 8 by a secondary conductor 7 with a circular section. According to the 0.6/1kv power cable, the insulating main cable cores are changed into sector shapes from circular shapes, so that the gap between the cable cores is effectively reduced; filling materials are saved and the production cost of the cable is reduced.
Description
Technical field
The present invention relates to field of cables, be specifically related to a kind of 0.6/1kv power cable.
Background technology
Power cable is mainly used in transmission and distributes high-power power, and have certain insulating properties and corrosion resistance, along with the high speed development of national economy and the progress of technology, market proposes the requirement of high-quality and low price to cable product.This just needs to carry out Improvement to existing conventional products, abundant excavation potential, to create larger economic benefit, the main push-towing rope core conductor of current power cable is mostly circular compacted stranded conductor, the insulation extrusion of this conductor and the technological operation of stranding all comparatively simple, but the insulated core of circle easily forms large gap when stranding, this just needs to fill cable with a large amount of auxiliary material, ensure the rounding aesthetic property of the stability that electric current is carried and cable, do the external diameter and weight that not only increase cable like this, virtually also improve the manufacturing cost of cable simultaneously.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the 0.6/1kv power cable that a kind of compact conformation, good insulation preformance, production cost are low is provided.
Technical scheme of the present invention is as follows:
0.6/1kv power cable of the present invention it include the secondary cable core of three groups of main push-towing rope cores and a group, it is characterized in that: main push-towing rope core and secondary cable core are coated with inner restrictive coating, steel wire armor layer is provided with outside inner restrictive coating, external sheath layer is provided with outside steel wire armor layer, between cable core, gap is provided with packed layer, described main push-towing rope core is that fan-shaped leading body extrudes main insulating layer and forms by cross section, and secondary cable core is that circular auxiliary-conductor extrudes secondary insulating barrier and forms by cross section.
Described main insulating layer and secondary insulating barrier adopt cross-linking polyethylene materials.
Described leading body and the sectional area ratio of auxiliary-conductor are 1:0.6.
Beneficial effect: insulation main push-towing rope core is changed into fan-shaped by the present invention by circle, effectively reduce the space between cable core, has saved inserts, reduces the production cost of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, leading body 2, main insulating layer 3, packed layer 4, inner restrictive coating 5, steel wire armor layer 6, external sheath layer 7, auxiliary-conductor 8, secondary insulating barrier
Embodiment
Its structure as shown in Figure 1: a kind of 0.6/1kv power cable, it comprises three groups of main push-towing rope cores and one group of secondary cable core, main push-towing rope core and secondary cable core are coated with inner restrictive coating 4, steel wire armor layer 5 is provided with outside inner restrictive coating 4, external sheath layer 6 is provided with outside steel wire armor layer 5, between cable core, gap is provided with packed layer 3, and described main push-towing rope core is that fan-shaped leading body 1 extrudes main insulating layer 2 and forms by cross section, and secondary cable core is that circular auxiliary-conductor 7 extrudes secondary insulating barrier 8 and forms by cross section; Described main insulating layer 2 and secondary insulating barrier 8 adopt cross-linking polyethylene materials; Described leading body 1 and the sectional area ratio of auxiliary-conductor 7 are 1:0.6.
Insulation main push-towing rope core is changed into fan-shaped by the present invention by circle, effectively reduce the space between cable core, has saved inserts, reduces the production cost of cable.
