Abstract
The utility model discloses a kind of anti-extrusion fireproof cable, include two oval oversheaths connected side by side, cable core one and cable core two is placed with respectively in the inside of two oval oversheaths, cable core one includes master core, control conductor and S type polyamide skeleton, master core is coated with polyvinyl chloride insulation layer successively in the outside of leading body, zinc-coated wire woven shield and aluminium strip lock armo layer are formed, described leading body is twisted by tin annealed copper wire bundle to form, described control conductor includes control conductor, described control conductor is twisted by zinc-plated nickel wire bundle to form, butyronitrile polyvinyl chloride insulation layer is coated with successively in the outside controlling conductor, plastic film lapping layer and galvanized steel strip armour.The utility model employs the oval oversheath connected side by side, and employs S type polyamide skeleton, increases the anti-extrusion and anti-twisting property of cable, employs the fire-resistant fireprotection layer of Ceramic silicon rubber, greatly strengthen fireproofing of cable function, safe and reliable.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of anti-extrusion fireproof cable.
Background technology
The situation that cable may be squeezed when transporting and use, cause the destruction of cable jacket breakage and internal structure, existing cable still can not realize high bending durability and high pliability simultaneously in addition, thus reduces the environmental suitability of cable.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of anti-extrusion fireproof cable.
The utility model is achieved through the following technical solutions:
A kind of anti-extrusion fireproof cable, include two oval oversheaths connected side by side, cable core one and cable core two is placed with respectively in the inside of two oval oversheaths, described cable core one includes master core, control conductor and S type polyamide skeleton, described master core is coated with polyvinyl chloride insulation layer successively in the outside of leading body, zinc-coated wire woven shield and aluminium strip lock armo layer are formed, described leading body is twisted by tin annealed copper wire bundle to form, described control conductor includes control conductor, described control conductor is twisted by zinc-plated nickel wire bundle to form, butyronitrile polyvinyl chloride insulation layer is coated with successively in the outside controlling conductor, plastic film lapping layer and galvanized steel strip armour, the control conductor described in nonwoven fabrics lapping layer formation is surrounded by after three being controlled conductor bundle strand, control conductor and master core is placed with respectively in the space up and down of S type polyamide skeleton, master core is placed with respectively at the left and right sides of S type polyamide skeleton, and outside be coated with successively ellipse scribble the fabric strip of semiconductive colloid and the fire-resistant fireprotection layer of oval Ceramic silicon rubber form described in cable core one, described cable core two is by being coated with oval dacron thread braid successively in outside after two above-mentioned master core pair twists and ellipsoidal glass fabric strip lapping layer is formed.
The utility model has the advantages that: the utility model employs the oval oversheath connected side by side, and employ S type polyamide skeleton, increase the anti-extrusion and anti-twisting property of cable, employ the fire-resistant fireprotection layer of Ceramic silicon rubber, greatly strengthen fireproofing of cable function, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
