Abstract
The utility model discloses an interlock type armoured mice-proof and termit-proof aluminium alloy cable. The interlock type armoured mice-proof and termit-proof aluminium alloy cable includes a cable core which comprises three groups of aluminium alloy conductors. The aluminium alloy conductor is formed by stranding a plurality of aluminium alloy wires. A silane crosslinked polyethylene layer is wrapped at the external surface of each aluminium alloy conductor as an insulation layer. A polyethylene belt is belted at the external surface of the cable core. An armor layer, formed by interlock and armouring of two layers of aluminium alloy belts, is wrapped at the external surface of the polyethylene belt. A polyethylene layer is wrapped at the external surface of the armor layer as a sheath. With the interlock type armoured mice-proof and termit-proof aluminium alloy cable, the problems that the noxious material used in a chemical method to protect the cable form termits will pollute environment and harm human body, and that it is difficult to produce a nylon sheath, print characters on the surface of nylon sheath, and keep the surface of nylon sheath uncracked, are solved.
Description
Technical field
The utility model relates to a kind of power cable transmission field, is specifically related to the termite-proof aluminium alloy cable of a kind of interlocking armouring protection against rodents.
Background technology
Early 1990s, Guangdong Jiangmen factory one workshop by the erosion of termite moth, is caused short circuit because of buried power cable, and causing has a power failure stops production a couple of days.The buried high-tension cable of Guangzhou factory in 1993, because of termite moth erosion short circuit, sets off an explosion.Eaten into erosion, short circuit power cut because of underground cable by termite for one in a certain villa cluster in November, 1999 Guangzhou.In Guangdong, because all kinds of buried cables of termite moth erosion cause fault to happen occasionally, because of its economic loss caused and consequence also very serious.Anti-termite power cable is divided into two large classes at present: chemical method is termite-proof, Physical is termite-proof.Chemical method is termite-proof is mainly to add termite-proof chemical agent in the sheath material of cable, make termite near or while biting cable jacket, be killed or walk quickly and keep away.Noxious substance in this kind of method can be to environment, human body is worked the mischief, and can not guarantee the long-term termite-proof performance of cable.During Physical is termite-proof, adopt extrudes one deck nylon sheath wire at cable surface more, but nylon sheath wire complex manufacturing, jacket surface cannot letterings, and the easy cracking and lose the termite-proof effect of protection against rodents of nylon sheath wire.
Summary of the invention
The utility model purpose is to provide the termite-proof aluminium alloy cable of a kind of interlocking armouring protection against rodents, this interlocking armouring protection against rodents termite-proof aluminium alloy cable solved the termite-proof middle noxious substance of chemical method to the pollution of environment, to the harm of health and nylon sheath wire complex manufacturing, jacket surface cannot lettering, the problem such as easy to crack.
For achieving the above object, the technical solution adopted in the utility model is: by the stranded core formed of three group aluminum alloy conductors, described aluminium alloy conductor is by some stranded the forming of aluminum-alloy wire, the one organosilane crosslinked polyethylene layer as insulation extrudes in described aluminium alloy conductor outer surface, one polyethylene band is wrapped in described core outer surface, the armour formed by two-layer aluminum alloy strip lock armo is coated on described polyethylene band outer surface, and a polyethylene layer as sheath extrudes in described armour outer surface.
Further improve technical scheme in technique scheme as follows:
1,, in such scheme, described aluminium alloy conductor is by 100 ~ 500 stranded forming of aluminum-alloy wire.
2,, in such scheme, the diameter of described aluminum-alloy wire is 0.40mm.
3, in such scheme, it is red, yellow, blue that the color of described organosilane crosslinked polyethylene layer is respectively, and its eccentricity is not more than 15%.
4, in such scheme, the average thickness of described polyethylene layer is 1.8 ~ 2.0mm, and its eccentricity is not more than 20%.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The termite-proof aluminium alloy cable of the utility model interlocking armouring protection against rodents, solved chemical method termite-proof middle noxious substance to the pollution of environment, to the harm of health and nylon sheath wire complex manufacturing, jacket surface cannot lettering, the problem such as easy to crack; Secondly, with in sheath, add chemicals to compare to have nontoxic, without the advantage such as ageing; With nylon sheath wire, compare have produce simple, jacket surface can lettering etc. advantage, and the easy cracking and lose the termite-proof effect of protection against rodents of nylon sheath wire, and aluminum alloy strip is not easy to get rusty, so steady quality, have the termite-proof effect of long-term protection against rodents.
