The utility model technical solution problem adopts following technical scheme:

A kind of answering machine data transmission cable of the utility model, its design feature are that conductor adopts solely strand annealed copper wire, extrude the polythene PE insulating barrier and constitute insulated wire cores on described conductor; Per two thoroughly do away with the edge cores is twisted into pair twist group or per four and thoroughly does away with the edge cores and be twisted into the star quad stranding group and form cable core, sets gradually total screen of overlapping wrapped polyester belt, tincopper fuse wire braided armor, drainage thread, the wrapped formation of aluminium-plastic tape on cable core from inside to outside; And on described total screen, set gradually comprehensive sheath, outer vertical bag that extrudes the PE plastics and constitute or the armour that extrudes the alibate of formation, the inner covering that extrudes formation, double-deck steel band formation from inside to outside, and the external sheath layer that extrudes formation.

It is the bare copper wire of 1.14mm or 1.53mm that described conductor adopts diameter.

Described polythene PE insulating barrier is the double hyer insulation that double-layer coextrusion forms, and outer layer thickness is 0.05-0.07mm.

In the described pair twist group two thoroughly done away with the pair twist pitch 100-110mm of edge core; The star quad stranding pitch that in the described star quad stranding group four thoroughly done away with the edge core is 130-140mm.

Described inner covering and external sheath layer are that material extrudes formation with LLDPE LLPE or high density polyethylene.

The utility model not only has the function of transmitting message data information and electric energy, also have anti-electromagnetic interference, insulation resistance height, compressive resistance height simultaneously, undistorted, the performance such as do not distort of transmission signals under high frequency, compared with the prior art, the utility model beneficial effect is embodied in:

1, conductor employing bare copper wire diameter is 1.14mm or 1.53mm conductor in the utility model, and its electricity function index satisfies the requirement of cable signal transmission parameter;

2, insulating barrier has adopted the polyethylene material of excellent electrical properties, mechanical performance excellence in the utility model, and adopted double-layer coextrusion technology, can be by in external insulation layer, adding the look mother, because the look mother is added on the insulation resistance that can reduce insulating barrier in the whole insulating barrier greatly.The utility model only adds the look mother in skin, improved the electric property of insulating barrier on the one hand, has improved insulation resistance; Can make the insulating outer layer skin be divided into different colors on the other hand, make things convenient for installation, laid, be convenient to safeguard

3, pair twist pitch 100-110mm in the utility model, star quad stranding pitch 130-140 has reduced line to attenuation constant and electromagnetic coupled, has improved the cable quality;

4, the utility model inner covering and external sheath layer are that material extrudes formation with LLDPE LLPE or high density polyethylene, and it is strong that its material has waterproof, anticorrosion, environmental protection, accommodative ability of environment, can satisfy the requirement of product adaptation complex environment.
