Abstract
The utility model discloses a 16-core data transmission cable and belongs to the cable field. The 16-core data transmission cable includes cable units, filling cores, a packing material layer, a shielding layer and a sheath; four cable units are provided; four line cores of the same specification and a filler at the center of the four line cores are stranded to together to form a round structure, and the round structure is wrapped with a thin-wall shielding layer, and therefore, one cable unit can be formed; each line core is composed of a conductor and an insulation layer, wherein the insulation layer uniformly seals the conductor; the cable units and the filling cores are arranged at intervals; the cable units and the filling cores are stranded together so as to form a round structure; the exterior of the round structure is wrapped with the packing material layer; the exterior of the packing material layer is wrapped with the shielding layer; and the exterior of the shielding layer is wrapped with the sheath. The rated voltage of the cable of the utility model is 300V. The cable has the advantages of low temperature resistance, high temperature resistance, light weight, excellent electrical properties as well as excrement mechanical and physical properties, and the like.
Description
Technical field
The utility model relates to field of cables, specifically, relates to a kind of 16 core data cables.
Background technology
The progressive let us of society improves constantly the requirement of security protection.Requiring that cable data cable transmission speed is faster, transmission bandwidth wider in, fire-resistant communication cable continued power ability in fire is also had to more and more higher requirement, and the insulated fireproof performance of fire-resistant communication cable is to continued power ability important in its fire.And the insulating material that prior art is used cannot guarantee that 16 core data cables can also keep basic transformation parameter in fire He after fire.
Utility model content
The technical problem that 1, will solve
The purpose of this utility model is to provide a kind of 16 core data cables that still can keep basic transformation parameter in fire and after fire.
2, technical scheme
For achieving the above object, the utility model adopts following technical scheme:
16 core data cables, comprise cable unit, filled core, the packing timber bed of material, screen and sheath; The number of described cable unit is four, each cable unit by the fillers in the middle of the identical core of four specifications and four cores be twisted into circular after parcel thin-walled screen form; Each core is comprised of conductor and insulating barrier, and insulating barrier evenly seals conductor; Cable unit and filled core are spaced, and cable unit and filled core twist together circular, packing timber bed of material parcel for outside; Described screen is wrapped in the outside of the packing timber bed of material, and described sheath is wrapped in the outside of screen.
Further, described conductor is the tin-coated copper wire of annealing flexibly.
Further, the material of described insulating barrier is foam crosslinked polyethylene.
Further, the material of the described packing timber bed of material is plastic adhesive tape.
Further, described screen is formed by the tin-coated copper wire braiding of annealing.
Further, the material of described sheath is that model is the crosslinked polyethylene of EM104, and sheath color is black, and sheath external diameter is 16.00 ± 0.5mm.
3, beneficial effect
(1) rated voltage for cable of the present utility model is 300V, has that low temperature resistant, high temperature resistant grade is high, lightweight, a distinguishing feature such as electric property and mechanical and physical performance excellence;
(2) conductor of the present utility model has adopted flexible annealing tin-coated copper wire, has increased the pliability of cable; Adopt low-smoke halogen-free polyolefin elastomeric material, make the bending force of cable less, increase the pliability of cable, and adopt halogen-free polyolefin elastomeric material, make it have good resistance to wear;
(3) the utility model adopts halogen-free low-smoke flame retardant material, when occurring, fire produces hardly toxic gas and dense smoke, be conducive to the smooth expansion of fire-fighting work, personnel shift, control spreading of fire, more can alleviate the secondary disaster that hydrogen halide causes precision instrument and equipments such as the instrument and meter in surrounding environment etc.;
(4) the utility model adopts sheath and insulating barrier all adopt cross-linking polyethylene materials, double-deck high temperature resistant, the highest high temperature resistant to 110 degrees Celsius, fail safe strengthens, make the fire resistance that cable is higher, there is more than 50200 transmission characteristic of standard EN, can in fire and after fire, keep substantially constant basic transformation parameter.
