Abstract
The utility model provides a shielded flame-retardant cabtyre cable for a coal mine. A cable core of the cable comprises a ground core conductor, three strands of power cores and a control core bundle consisting of seven strands of control cores. A sheath structure adopts a three-layer structure and is provided with an inner rubber sheath, an inner sheath weaving layer and an outer rubber sheath from inside to outside sequentially. The three-layer sheath structure is adopted to replace the conventional single-layer sheath structure and the sheath material adopts the rubber with flame retardance, high tensile property and high tear resistance, thus, shielded flame-retardant cabtyre cable obviously improves the tensile property and tear resistance mechanical performances of the sheath so as to guarantee safety use of the cable in the coal mine and is suitable to popularize and use in the coal industry.
Description
Technical field
The utility model belongs to the cables manufacturing technical field, is specifically related to a kind of colliery with fire retardant jacket high strength rubber sleeve flexible cable.
Background technology
Coal is the first energy of China, and it is the first that output occupies the whole world.Along with coal industry is integrated continuing to increase of reorganization dynamics, the mechanization degree of coal enterprise is more and more high, coal industry also constantly increases the demand of various mining Plastic-sheathed Cables, in order to ensure coal mining safety, the security reliability of cable is had higher requirement.Because regular meeting suffers pounding pressure, pushing, impact, scratch, rub and other mechanical force of coal cinder during cable under mine; add the influence of underground wet environment; the sheath rubber on common cable surface is because tensile strength and tearing toughness are poor; very easily damage and lose the effect of protecting cable, bury potential safety hazard to the operation of coal industry.Therefore, press for the mining Plastic-sheathed Cable of high strength that the band fire retardant jacket is provided for coal industry.
Summary of the invention
The purpose of this utility model is to provide a kind of fire-retardant, high strength, resistant to elevated temperatures colliery rubber sleeve flexible cable.
To achieve these goals, technical solutions of the utility model are as follows:
The colliery comprises with the cable core of shielding flame retardant type rubber sleeve flexible cable: the ground wire core conductor of cable core central authorities and all around three strands of power cores and one control core bundle, and per share power core is followed successively by power line core conductor, power line core insulation layer and power line core insulation screen from the inside to the outside; Described control core bundle is made up of seven strands of control cores, and per share control core is followed successively by control line core conductor and control line core insulation layer from the inside to the outside, and control core bundle is provided with control line core rubber sheath outward.
The jacket structure of cable adopts three-decker, promptly extrudes earlier rubber sheath in fire-retardant, high anti-of one deck, the high tear resistance on cable conductor; Fire-retardant, the high strength of braiding one deck, resistant to elevated temperatures inner sheath braid on inner sheath then; On the inner sheath braid, extrude rubber sheath outside fire-retardant, high anti-of one deck, the high tear resistance again.
Rubber sheath, outer rubber sheath and control core rubber sheath all adopt ZRXH-03A type sheath rubber in described, and its thickness is 2.5mm.
Described inner sheath braid is high strength, the resistant to elevated temperatures fire-retardant synthetic fibre silk that spins, and thickness is 0.7mm.
Advantage of the present utility model is:
Keeping under the cable cover(ing) nominal thickness prerequisite, adopt three layers of jacket structure to substitute common individual layer jacket structure, that interior oversheath all adopts is fire-retardant, highly anti-ly open, high tear resistance rubber, and one deck is fire-retardant, high strength, resistant to elevated temperatures inner sheath braid embed in the oversheath rubber, make cable cover(ing) more anti-ly pound pressure, push, impact, scratch, rub and other mechanical force, ensure the safe handling of cable in the colliery, eliminated the potential safety hazard that cable brings for the coal operation.
