Abstract
The utility model discloses a tensile waterproof type shielding control cable comprising a plurality of insulation cores. An outer side of each of the insulation cores is wrapped by a copper wire braiding branch shielding layer. The insulation cores and a reinforced steel wire are intertwisted together, and then are wrapped by a taped covering in a coiled manner. An inner side of the taped covering is filled with waterproof yarns in an extruded manner, and an outer side of the taped covering is wrapped by a seamless metal sleeve. An outer side of the seamless metal sleeve is sequentially wrapped by a low smoke zero halogen polyolefin inner sheath. An outer side of the inner sheath is sequentially wrapped by a copper strip main shielding layer, a polyester band, and an outer sheath. In the utility model, the design of the intertwisting of the insulation cores and the reinforced steel wire is adopted, therefore the tensile performance of the control cable can be effectively improved; the waterproof yarns are disposed in the inner side of the control cable, and the design of the seamless metal sleeve is adopted, therefore the waterproof performance of the control cable can be effectively improved; the double layer shielding design of the copper wire braiding branch shielding layer and the copper strip main shielding layer is adopted, therefore the anti-interference capability of the control cable can be greatly improved, and the adaptability of the control cable in the complicated environment is strong.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of tension water proof type shielding control cables.
Background technology
Existing control cables mostly is by core and is coated on the outer field screen of core and the insulating sleeve layer consists of, the water proofing property of this type of cable, pull resistance and shield effectiveness are all undesirable, in the use procedure of control cables, sometimes need built on stilts laying, this tensile property to control cables is had relatively high expectations, the tensile property of general control cable is poor, is prone to accidents; Because the environment for use of control cables is complicated, have under the torrent wet environment such as being used in hydroelectric station etc., then there is potential safety hazard in the relatively poor control cables of water proofing property.
The utility model content
The purpose of this utility model provides a kind of tension water proof type shielding control cables, and is not good with the water resistance, tensile property and the shield effectiveness that solve traditional control cables in the prior art, can not satisfy instructions for use, and have the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tension water proof type shielding control cables, it is characterized in that: include several insulated wire cores, every eradication edge core is coated with the proof copper-wire braided sub-shield, be surrounded with lapping layer after several insulated wire cores are stranded with the reinforcement steel wire, extrude in the described lapping layer and be filled with group water yarn, described lapping layer is coated with the seamless metal cover, and described seamless metal cover is outer to be coated with the low-smoke halogen-free polyolefin inner sheath successively, and described inner sheath is coated with the total screen of copper strips, polyester belt and oversheath outward successively.
Described a kind of tension water proof type shielding control cables, it is characterized in that: described seamless metal cover adopts metal bellows to make.
Described a kind of tension water proof type shielding control cables, it is characterized in that: described lapping layer adopts fluoroplastics to make.
Described a kind of tension water proof type shielding control cables, it is characterized in that: described inner sheath and oversheath adopt silicon rubber to make.
The beneficial effects of the utility model are:
The utility model adopts insulated wire cores and strengthens the stranded design of steel wire, effectively promoted the tensile property of control cables, inside is filled with water blocking yarn, and adopt the design of seamless metal cover, effectively promoted the water resistance of control cables, and adopt the double layer screen design of the total shielding of proof copper-wire braided separated-shielding and copper strips, significantly promoted the antijamming capability of control cables, so that control cables has stronger adaptability under the environment for use of complexity.
