Abstract

The utility model discloses a special weatherability retinue cable of harbour machinery, including the cable core, the cable core includes conductor conductor, the cable core is equipped with conductor conductor, inner sheath, shielding layer and oversheath from inside to outside in proper order, and is equipped with the filling layer between the adjacent conductor conductor, conductor conductor includes the tensile sinle silk, and the outer wall of tensile sinle silk parcel has a wire, the wire includes the copper wire, the outer wall parcel of copper wire has the insulating layer, this special weatherability retinue cable of harbour machinery, and the wire rod is soft, and bend radius is little, and the manipulator that can adapt to little corner uses, and different environment uses down, pulls the performance height, long service life.

Description

A kind of harbour machinery dedicated weather-proof trailing cable

Technical field

The utility model relates to field of cable technology, is specially a kind of harbour machinery dedicated weather-proof trailing cable.

Background technology

Sea-freight prosperity makes harbour machinery develop rapidly, but because harbour machinery lifting is frequent, matched cable often will do high-speed mobile, bear larger pulling force and bend, various breakage will be there is in traditional common cable about using half a year, impact uses, so need novel height, to pull the cable that performance and twisting property require supporting with it.The environment of harbour service is different from general room environment, environment is changeable, and this just requires that cable is also wanted, with oil resistant having while height pulls performance, corrosion-resistant, high temperature resistant, low temperature resistant, salt water resistance, rub resistance, the particular/special requirements such as UV resistant, for this reason, we propose a kind of harbour machinery dedicated weather-proof trailing cable.

Summary of the invention

The purpose of this utility model is to provide a kind of full-automatic plastic-steel to plant the energy-saving electric machine of tooth, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of harbour machinery dedicated weather-proof trailing cable, comprise cable core, described cable core comprises core conductor, and described cable core is provided with core conductor, inner sheath, screen and oversheath from inside to outside successively, and is provided with packed layer between adjacent lines core conductor, described core conductor comprises tension core, and the outer wall of tension core is enclosed with wire, described wire comprises copper wire, and the outer wall of described copper wire is enclosed with insulating barrier.

Preferably, described packed layer is interwoven by high strength aramid fiber yarn and cotton synthetic fibre silk.

Preferably, described cored wire conductor is double wired conductor.

Preferably, described screen is formed by the meticulous proof copper-wire braided being no less than 20 groups of high-flexural strengths.

Compared with prior art, the beneficial effects of the utility model are: this harbour machinery dedicated weather-proof trailing cable, and wire rod is soft; bending radius is little, and the manipulator that can adapt to small angle tower uses, when carrying out high-speed mobile; can bear larger pulling force and bending force, the protection of oversheath makes the prolongation in useful life, is not vulnerable to the impact of extraneous changeable environment; also there is oil resistant pulling of high strength simultaneously, corrosion-resistant, high temperature resistant; low temperature resistant; salt water resistance, rub resistance, the specific functions such as UV resistant.
