Second step: extrusion step: after conductor draws tank, opens extruding machine, and the jacket layer material of thawing is entered in the core rod gap with die sleeve by extrusion head, is extruded outside conductor by sheath material by fashion of extrusion；Wherein, the internal diameter of die sleeve is more than the outer peripheral diameter of core rod；The material of described restrictive coating comprises following component by weight: polyethylene: 82～84 parts, ethylene vinyl acetate copolymer: 5～7 parts, fire retardant: 5～7 parts, coupling agent: 0.5～1.5 part, antioxidant: 1～3 part, tripolycyanamide: 0.5～1.5 part, ethyl silicon oil: 0.5～1.5 part, poly dimethyl silicon siloxanes: 1～3 part, titanium dioxide or carbon black: 2～4.5 parts；Described fire retardant is magnesium hydroxide or aluminium hydroxide or sodium bicarbonate；The model that described coupling agent is is TMC-38S；Described antioxidant is thio-2 acid octadecyl ester.
It should be noted that in the method for the present invention, also before conductor is passed the hole, location on jig, conductor can be made to first pass through metal material treatment fluid, and dry online in distraction step；Or before conductor is passed the hole, location on jig, coat oily substance at conductive surface, so, conductive surface or stranded gap would not be bonded with jacket layer material, so can construct more easily and continue.
Certainly, can also is that before the mistake conductor bores that conductor passes on core rod, it is coated with in waterstop or polyester belt or other suitable band, such conductive surface or stranded gap outside conductor and also would not be bonded with jacket layer material, so can construct more easily and continue.
Cable in the present invention, only has conductor and restrictive coating, and therefore, the structure outside diameter of cable simpler, same specification is less, material cost is lower；Simultaneously as lacked isolation step, therefore, manufacture convenient, manufacture in machinery equipment put into less, artificial/power consumption and more save；Therefore manufacturing cost is lower；In the present invention, the existence of recognition unit, can be in the case of not having insulating barrier and not having colour recognition, it is possible to identifies the accurate location of conductor in cable, the existence of recognition unit is possible not only to make conductor can recognize that, and owing to consumptive material reduces therefore significantly reduces cost；The existence of light unit in the present invention so that cable not only has the function of transmission of electricity, and can transmit optical signal and for signal monitoring, greatly expands the range of cable.In the present invention, due to the special formulation of cable sheath material so that cable is provided with more excellent insulation, proof voltage, anti-ant, fire-retardant, fire resistance.In this cable, when using stranded conductor, product is soft, is more easy to continue and construction is laid.
Therefore, the present invention has a following main beneficial effect: product structure is simpler, cost is lower, manufactures is easier, equipment investment is less in manufacture.
Heretofore described a kind of cable with simple structure, when wherein having optical fibers, is a kind of easy structure optical cable.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that the design of the present invention can be implemented to use by other various forms, and they also fall within protection scope of the present invention.
