Abstract
The utility model discloses a kind of high-tension cable suitable for underground engineering, the space that the high-tension cable suitable for underground engineering is included between conductor layer, the second insulating barrier, the first separation layer, woven shield, the second separation layer, water-proof jacket layer, the conductor layer successively from inside to outside is filled with ointment.The conductor layer is copper stranded conductor, the copper stranded conductor is coated with the first insulating barrier and waterstop in itself, the insulating barrier is 0.3mm TPE insulating barriers, the woven shield is tinned wird screen layer, the waterproof layer is used, and the water-proof jacket layer material is the blending resin overcoat of thermoplastic elastic TPE and polyethylene.High-tension cable of the present utility model has stronger mechanical performance and block-water performance, and water-fast, decay resistance, service life is longer.
Description
Technical field
The utility model is related to field of cables, more particularly to a kind of high-tension cable suitable for underground engineering.
Background technology
With the progress of scientific and technological level, the rapid growth of national economy, developing rapidly for underground engineering is electric to electric wire
The demand of cable also gradually increases, and diversified trend is presented, the water resistance of cable is also gradually stepped up.Current cable is most
With insulate, it is corrosion-resistant based on, filler is water blocking yarn mostly, and waterproofing rope, water-fast effect is bad.
Utility model content
There is provided a kind of height suitable for underground engineering for the defect for aiming to overcome that prior art of the present utility model
Voltage cable, the high-tension cable suitable for underground engineering from inside to outside successively include conductor layer 1, the second insulating barrier 4, first every
Absciss layer 5, woven shield 6, the second separation layer 7, water-proof jacket layer 8.
The conductor layer 1 is copper stranded conductor, and the copper stranded conductor is coated with the first insulating barrier 2 and waterstop 3, described first in itself
Insulating barrier 2 is closely extruded on described copper stranded conductor, and the waterstop 3 is coated on the described outside of the first insulating barrier 2；It is described
Space between conductor layer 1 is filled with ointment 9；The insulating barrier 4 of first insulating barrier 2 and second is 0.3mm TPE insulating barriers.
The first described separation layer 5 and the second separation layer 7 are formed using Mylar material is wrapped, the braid shielded
Layer 6 is tinned wird screen layer, and the woven shield 6 is close to wrapped on first separation layer 5, second separation layer
7 are closely coated on the outside of woven shield 6.
The water-proof jacket layer 8 is the blending resin overcoat of thermoplastic elastic TPE and polyethylene, the water-proof jacket layer
8 are closely extruded on the second described separation layer 7.
The insulating materials uses TPE, there is very high insulaion resistance, even if remaining to keep very high insulated electro after immersion
Resistance, with very strong elongation at break and very high tensile strength, very strong low temperature tolerance ability.
The cable has the waterstop of wire in itself, water-proof jacket layer, the filler ointment between additional wire there is provided
It is triple to ensure so that the waterproof of this wire, block-water effect are splendid；The water-proof jacket layer uses thermoplastic elastic TPE and poly- second
The blending resin overcoat of alkene integrates waterproof and protective effect, saves cable cost, service life extension.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description, embodiment is only this reality
With new one embodiment, for those of ordinary skill in the art, without having to pay creative labor, go back
Other embodiments can be obtained with reference to the accompanying drawings, also within protection scope of the present invention.
Fig. 1 is the structural representation for the high-tension cable that the utility model is applied to underground engineering；
Fig. 2 is conductor layer structural representation in Fig. 1.
Reference：1- conductor layers, the insulating barriers of 2- first, 3- waterstops, the insulating barriers of 4- second, the separation layers of 5- first, 6-
