Description of reference numerals：Conductor 1, one side calcining mica tape 2, insulating barrier 3, tinned copper wire braiding split screen layer 4, polyester belt Lapping layer 5, packing 6, optical cable 7, the total screen layer 9 of expanded glass fiber rope 8, tinned copper wire braiding, aramid yarn enhancement layer 10, sheath 11.

Specific embodiment

With reference to specific accompanying drawing, the utility model is described in further detail.

As shown in Figure 1：Communication system comprehensive wiring special optical cable described in the utility model includes cable core, and cable core is by four lines The centrally disposed packing 6 of core and a structure arranged clockwise stranding of the use of optical cable 7 0+5, four cores and optical cable 7, line The gap of core and optical cable 7 carries out stranding using expanded glass fiber rope 8, and stranding roundness is not less than 15%；In expanded glass fiber rope 8 Outside weaves one layer of total screen layer 9 of tinned copper wire braiding, and the count of the total screen layer 9 of tinned copper wire braiding is 90%；Described tin plating The outside that proof copper-wire braided always shields layer 9 weaves one layer of aramid yarn enhancement layer 10, and one layer of shield is extruded in the outside of aramid yarn enhancement layer 10 Set 11.

The optical cable 7 uses 9/125 optical cable of 4 cores.

The core include conductor 1, conductor 1 using 5 class tinned copper wires using it is regular it is stranded by the way of be made, in conductor 1 The wrapped one side calcining mica tape 2 in outside, the mica of one side calcining mica tape 2 is faced outwardly, Duplication ＞ 40%；Forged in the one side The outside of glowing cloud master tape 2 extrudes a layer insulating 3, and one layer of tin-coated copper braiding split screen layer 4, braiding are woven in the outside of insulating barrier 3 Density is 90%；In the outside wrapped polyester belt lapping layer 5 of tin-coated copper braiding split screen layer 4, polyester belt lapping layer 5 is put up Rate ＞ 25%.

The operation principle of communication system comprehensive wiring special optical cable described in the utility model：

1st, Cable Bending Radius is reduced：The flexibility and resist bending ability of cable depend primarily on the structure of cable, and The structure of conductor wire core plays vital effect again in the construction of cable.In order that conductor wire core is soft, resist bending, with compared with Conductance high, conductor is thin monofilament, beam stock, the compound structure for twisting.For the Special use mode of cable, using filament diameter The no more than tinned copper wire of 0.31mm；Make conductor structure more stable, tight journey using the regular stranded mode of 1+6 during process Degree is high, and external diameter is small, and conductor wire core pliability is good.

Other armature of cable layer uses tincopper fuse wire braided armor, and count is 90%, and wire sheathing can play screen The effect of cable core is covered and protects, while the braiding layer is also sufficiently flexible.

2nd, electromagnetic interference performance is improved：The shielding of cable is compiled outside each core using in " split screen+total screen " structure, i.e. cable Tin-coated copper braiding split screen is knitted, count is 90%, this Rotating fields can cause that the electromagnetic wave that each core of cable is produced does not disturb it His core, solves the problems, such as to be disturbed between each core；One layer of braiding total screen of tin-coated copper braiding is woven outside cable core after stranding, Count is 90%, and this Rotating fields can further improve each core anti-electromagnetic interference capability in cable core.

3rd, optical fiber is combined：Because the function of cable in the prior art is more single, set in cable described in the utility model Optical cable, because optical fiber will not be subject to electromagnetic interference capability, weight is also relatively light, and transmission quantity is big, realizes cable multi-functional.
