CN201340748Y - PE insulating PVC protective sleeve rare-earth wire shielding cable - Google Patents

Abstract

The utility model discloses a PE insulating PVC protective sleeve rare-earth wire shielding cable, comprising a PVC protective sleeve layer, a rare-earth wire shielding layer, a polyester band lapping layer, a plurality of wire cores and PE insulating layers which are coated on the wire cores; a plurality of the wire cores, which are coated with the PE insulating layers are twisted for forming a cable core; the polyester band lapping layer is coated outside the cable core, and the rare-earth wire shielding layer and the PVC protective sleeve layer are sequentially coated outside the polyester band lapping layer. In a word, the cable carries out shielding protection to cable conductors such as oxidation, corrosion, metamorphism, rigidification and ageing, the shielding cable weaved by a protective sleeve and rare-earth wires increases tensile stretch and intensity and prolongs the service life of the cable; after the test, the electrical loss can be reduced and the cost consumption of the product is effectively reduced; in addition, the cost of users is reduced, the shielding efficiency is higher than that of copper when at high frequency, and the application range is more wide.

Description

PE insulation PVC sheath rare-earth wires shielded type cable

Technical field

The utility model relates to the cable technology field, specifically relates to a kind of PE insulation PVC sheath rare-earth wires shielded type cable.

Background technology

Many weeks, traditional cable is by core and is wrapped in the outer field insulating sleeve layer of core and constitutes, the influence that the cable conductor meeting is oxidated, burn into rotten, sclerosis reaches factors such as wearing out of this type, its percentage elongation and intensity all can reduce, cause cable life to shorten, cause electric loss rate to improve simultaneously, increased the cost consumption of product, increased cost for enterprise and user.Therefore how to make cable can improve these performances and become the problem that current cable technology industry is particularly paid close attention to.

The utility model content

The purpose of this utility model is to overcome the problems referred to above, provides a kind of shielding good, can prevent effectively that oxidation, burn into go bad, harden and aging PE insulation PVC sheath rare-earth wires shielded type cable.

For reaching the purpose of foregoing invention, the technical scheme that is adopted is: a kind of PE insulation PVC sheath rare-earth wires shielded type cable, comprise PVC restrictive coating, rare-earth wires screen, polyester belt lapping layer, several core and be wrapped in the outer PE insulating barrier of every core, the described mutual stranded formation cable conductor of several cores that is enclosed with the PE insulating barrier, the polyester belt lapping layer is wrapped in outside this cable conductor, and the polyester belt lapping layer outside is enclosed with rare-earth wires screen and PVC restrictive coating successively.

In sum, the utility model is rotten to the anti-oxidation of cable conductor, burn into, sclerosis, agingly carry out shielding protection, is woven into shielded type cable by sheath, rare-earth wires, has strengthened percentage elongation and intensity, has prolonged useful life of cable; Also can be reduced through evidence electricity loss rate, effectively reduce product cost consumption.Shield effectiveness when reducing user cost, its high frequency is better than copper, and the scope of application is more extensive.
