Abstract
Provided is a 0.6/1 kV power cable, comprising three groups of main cable cores and a group of auxiliary cable core. An inner sheath layer 4 wraps outside the main cable cores and the auxiliary cable core. A steel wire armoring layer 5 is disposed outside the inner sheath layer 4. An outer sheath layer 6 is disposed outside the steel wire armoring layer 5. A filler layer 3 is disposed among gaps of the cable cores. The main cable core is formed by extruding a main insulating layer 2 on a main conductor 1 whose section is in a fan shape. The auxiliary cable core is formed by extruding an insulating layer 8 on an auxiliary conductor whose section is round. The insulating main cable cores are changed into fan-shaped from round, thereby effectively reducing gaps among the cable cores, saving fillers, and reducing production cost of the cable.
Description
Technical field
The utility model relates to field of cables, is 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, has certain insulating properties and corrosion resistance, and along with the high speed development of national economy and the progress of technology, market has proposed high-quality and requirement low price to cable product.This just need to carry out Improvement to existing conventional products, fully excavate potential, to create larger economic benefit, the main push-towing rope core conductor of power cable is mostly circular compacted stranded conductor at present, the insulation extrusion of this conductor and the technological operation of stranding are all comparatively simple, but circular insulation cable core easily forms large gap when stranding, this just need to fill cable with a large amount of auxiliary material, guarantee the stability of electric current conveying and the rounding aesthetic property of cable, do so the external diameter and the weight that have not only strengthened cable, virtually also improved the manufacturing cost of cable simultaneously.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of compact conformation, good insulation preformance, 0.6/1kv power cable that production cost is low are provided.
The technical solution of the utility model is as follows:
It includes three groups of main push-towing rope cores and one group of secondary cable core 0.6/1kv power cable described in the utility model, it is characterized in that: main push-towing rope core and secondary cable core are coated with inner restrictive coating, inner restrictive coating is provided with wire armoring layer outward, wire armoring layer is provided with external sheath layer outward, 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: the utility model is changed into insulation main push-towing rope core fan-shaped by circle, effectively reduced the space between cable core, has saved inserts, has reduced the production cost of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, leading body 2, main insulating layer 3, packed layer 4, inner restrictive coating 5, wire armoring 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, the outer wire armoring layer 5 that is provided with of inner restrictive coating 4, the outer external sheath layer 6 that is provided with of wire armoring 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.
The utility model is changed into insulation main push-towing rope core fan-shaped by circle, effectively reduced the space between cable core, has saved inserts, has reduced the production cost of cable.
