Abstract
The utility model discloses a high insulation anti-interference waterproof wideband digital cable belonging to the transmission carrier range of digital communication, comprising from inside to outside: a conductor, the outside of which is covered with an insulation layer, a cable core, petroleum jelly filled around the core and an inner belting layer, a screening layer, an outer belting layer and a restrictive coating covered in turn on the outside of the core. The conductor is made of a copper wire or a tinned copper wire, the insulation layer is covered on the outside of the conductor. Two insulation cores are stranded into a twin according to different pitches, and a plurality of pairs of windings constitutes the cable core. The inner belting is overlapped on the outside of the core. The petroleum jelly is continuously filled with gaps of the cable core and the inner belting. The compound screening layer, the outer belting and the restrictive coating are covered on the outside of the inner belting. The cable has advantages of environmental protection, high insulation, dampproof and waterproof and excellent anti-interference performances.
Description
Technical field
The utility model belongs to digital communication and transmits carrier scope, the anti-interference wideband digital cable that blocks water of particularly a kind of high insulation.
Background technology
Along with the high speed development of modern communications cause, the popularization of digital communication and information superhighway, the use of wideband digital cable is more and more, and environment for use also becomes increasingly complex.How to improve the insulation property of present wideband digital cable, the anti-interference and anti-performance of divulging a secret becomes cable manufacturer urgent problem.
Pay attention to day by day along with people's environmental protection; countries in the world have proposed more strict requirement to the environmental-protecting performance of cable; but use more fire proofing in the cable at present, generally contain harmful substances such as lead, cadmium and many bromides, do not satisfy requirements of green environmental protection.
In addition, present wideband digital cable does not possess the moisture-proof function of blocking water, at some wet environments or grown service time and caused cable performance to descend easily.
Summary of the invention
The purpose of this utility model is not possess the moisture-proof function of blocking water at wideband digital cable in the prior art, at some wet environments or grown service time and caused cable performance to descend easily and do not satisfy the deficiency of requirements of green environmental protection, and provide a kind of high insulation the anti-interference wideband digital cable that blocks water.Described wideband digital cable comprises: conductor, and the outer interior belting layer that coats successively of petroleum jelly of filling around conductor outsourcing insulating layer coating, cable core, the heart yearn and heart yearn, composite shielding layer, outer belting layer, restrictive coating constitute; It is characterized in that: in the cable core gap and the band gap evenly continuous fill up petroleum jelly.
Described conductor extrudes the insulating barrier of layer of polyethylene outward, and two thoroughly do away with the edge lead forms one to the line group by the stranded back of different pitches, then by the line group being rearranged cable core in order, the interior belting layer of the outer overlapping wrapped polyester belt of heart yearn.
Described composite shielding layer is at the two-sided aluminium foil layer of the interior belting layer overlapping coating in outside, is provided with a drain wire of vertically placing in aluminium foil, is provided with the copper wire braid outside aluminium foil.
The outer belting layer of the outer overlapping again coating polyester belt of described composite shielding layer.Belting layer extrudes flexible PVC or the TPU polyurethane jacket with environmental protection flame retardant outward outside.
The beneficial effects of the utility model are: improved the insulation property of cable, its insulation resistance index is greater than 100000M Ω km; Improve the cable interference free performance and can be used for the occasion that signal is intensive, security performance is had relatively high expectations; This cable has moistureproof block-water performance, has improved cable useful life.The utility model does not contain harmful substances such as lead, cadmium, many bromides, meets requirements of green environmental protection.
