Abstract

The utility model discloses a high flexible towline cable applied for electrical and electronic device inside and outside wiring. The high flexible towline cable comprises four conductors. A bundle of core rope formed by twisting steel wire ropes is arranged in the four conductors respectively. The core rope is wrapped with a tape layer, and the thickness of the tape layer 3 is no less than 0.15mm. The four conductors are successively wrapped with a fireproof layer and an insulation layer respectively. The four conductors which are wrapped with the insulation layer are mutually twisted to form a cable core. The cable core is successively wrapped with a liner layer and a sheath layer. According to the utility model, the design is reasonable; the core rope is arranged in the conductor; the tape layer and the fireproof layer are arranged outside the core rope and the conductor respectively, wherein the tape layer and the fireproof layer are made of fireproof materials; the dragging resistance performance of the cable is improved; the fireproof performance of the cable is improved; in addition, the cable further has great performances of oil resistance, water resistance and crushing resistance.

Description

The high flexibility drag chain cable is used in the inside and outside wiring of a kind of Electrical and Electronic equipment

Technical field:

The utility model relates to power cable, relates in particular to the inside and outside wiring of a kind of Electrical and Electronic equipment and uses the high flexibility drag chain cable.

Background technology:,

Though wires and cables industry is a supporting industry just, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application very extensively relates to industries such as electric power, building, communication, manufacturing, and is all closely related with each department of national economy.

Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire comprises that mainly bare wire, electromagnetic wire and electrical equipment and electrical are with insulated electric conductor, power cable, telecommunication cable and optical cable.

Cable for wiring usefulness inside and outside the Electrical and Electronic equipment; There is defective in previous structural design; Can not satisfy the demand of actual working environment, often because a little less than the bending property, oil resistance, make cable rupture in actual use, inter-adhesive etc. can not the normal delivery data message.

The utility model content:

In order to solve the prior art problem, the high flexibility drag chain cable is used in the inside and outside wiring of a kind of Electrical and Electronic equipment of the purpose of the utility model, and reasonable in design has satisfied the inside and outside wiring of Electrical and Electronic equipment and used, and result of use is good, and the life-span is long.

The technical scheme of the utility model is following:

The high flexibility drag chain cable is used in the inside and outside wiring of Electrical and Electronic equipment; Comprise four conductors, it is characterized in that: be respectively equipped with the core rope of the stranded formation of a branch of steel wire rope in described four conductors, the core rope is wrapped with belting layer; Belting layer thickness is not less than 0.15mm; Four conductors are enclosed with fireprotection layer, insulating barrier outward respectively successively, and four conductors of wrap insulate layer stir each other and close the formation cable core, and cable core is enclosed with inner covering, restrictive coating outward successively.

The high flexibility drag chain cable is used in the inside and outside wiring of described Electrical and Electronic equipment, and it is characterized in that: described belting layer, fireprotection layer all adopt the wrapped formation of mylar tape.

The high flexibility drag chain cable is used in the inside and outside wiring of described Electrical and Electronic equipment, and it is characterized in that: the wrapped rate of putting up of described belting layer is not less than 30%, and the wrapped rate of putting up of fireprotection layer is not less than 35%.

The utility model has the advantages that:

The utility model reasonable in design; Be provided with the core rope in the conductor; Core is restricted outer and conductor is respectively equipped with belting layer, the fireprotection layer that fire proofing material is processed outward; Not only improved the anti-performance that pulls of cable, also improved the fireproofing of cable performance, this outer cable also has good oil resistant, waterproof, anti-extrusion performance.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Embodiment:

Referring to Fig. 1:

The high flexibility drag chain cable is used in the inside and outside wiring of Electrical and Electronic equipment; Comprise the core rope 2 that is respectively equipped with the stranded formation of a branch of steel wire rope in 1, four conductor 1 of four conductors, core rope 2 is wrapped with belting layer 3; Belting layer 3 thickness are not less than 0.15mm; Be enclosed with fireprotection layer 4, insulating barrier 5 respectively successively outside four conductors 1, four conductors of wrap insulate layer 5 stir each other and close the formation cable core, and cable core is enclosed with inner covering 6, restrictive coating 7 outward successively.

Belting layer 3, fireprotection layer 4 all adopt the wrapped formation of mylar tape.

The wrapped rate of putting up of belting layer 3 is not less than 30%, and the wrapped rate of putting up of fireprotection layer 4 is not less than 35%.

Four conductors 1 adopt multiplies carefully to be twisted into the ultra-fine bare copper wire of bundle, and insulating barrier adopts special PVC compound core insulation, and the cable core stranding is with very little pitch, add that high-intensity band is wrapped to be tightened, and restrictive coating is with special PVC compound enhancing oil-resisting type oversheath.

Through verification experimental verification: cable surpasses 1,000 ten thousand reversed bendings in the useful life of drag chain system, and the black external sheath layer strengthens the oil resistant characteristic, and adhesion mutually is particularly suitable for the various industrial environments such as mechanical part of lathe and complete production unit.
