Abstract
The utility model discloses a high-insulation communication cable, which comprises cable cores, a sheath layer, a lapping layer, a meshed strip, an aluminum strip and a braid, wherein the lapping layer, the meshed strip, the aluminum strip and the sheath layer are sequentially coated outside the cable cores; the lapping layer is formed by lapping at least two polyester strip layers; the polyester strip layers have different lapping directions; the meshed strip is a corrugated meshed strip; and the braid is longitudinally arranged between the meshed strip and the aluminum strip. The lapping directions of the lapping layer are changed, and the corrugated meshed strip is lapped outside the lapping layer, so that the air content in the communication cable is increased, and the high insulation performance of the communication cable is guaranteed.
Description
Technical field
The utility model relates to a kind of telecommunication cable, specifically, relates to a kind of high insulating communication cable.
Background technology
For improving the insulation property of telecommunication cable, traditional high insulating communication cable is chosen in belting layer usually and adds micro bubbles, promptly utilizes network-like polyethylene or polypropylene tape that it is carried out wrapped processing.But behind this reticulate pattern strips embossing, in wrapped process, be easy to evened up, and air content is low, influences the insulation property of telecommunication cable.
Summary of the invention
The technical problem that the utility model solved provides a kind of high insulating communication cable, utilizes the outer of reticulate pattern strips to hold, and increases telecommunication cable air content, has guaranteed the high insulating property of telecommunication cable.
Technical scheme is following:
A kind of high insulating communication cable comprises cable core, restrictive coating, also comprises belting layer, reticulate pattern strips, aluminium strip and drain wire; Said cable core is coated with said belting layer, reticulate pattern strips, aluminium strip and restrictive coating outward successively, vertically is provided with said drain wire between said reticulate pattern strips and the aluminium strip.
Further: said cable core is served as reasons 2 form the line group is stranded at least, said to the line group by 2 stranded forming of lead.
Further: said lead comprises the insulating barrier that conductor is outer with being coated on conductor.
Further: said conductor is the solid copper conductor, and said insulating barrier is a polyolefin insulation layer.
Further: said belting layer is by at least 2 layers of wrapped forming of polyester belt, every layer of lapping direction difference.
Further: said reticulate pattern strips is the corrugated reticulate pattern strips.
Further: said drain wire is that diameter is the tinned copper wire of 0.5mm.
The utility model advantage and beneficial effect are embodied in the following aspects:
1, the high insulating communication cable of the utility model adopts the multi-layered polyester band wrapped, and every layer of lapping direction difference guaranteed lapping simultaneously;
2, it is wrapped that the utility model adopts the corrugated reticulate pattern strips outside polyester belt, increased air content in the cable, improved the insulation property of telecommunication cable;
3, the high insulating communication cable of the utility model adopts the mode of aluminium strip outsourcing and cloth drain wire, has guaranteed the shielding properties of cable.
Description of drawings
Fig. 1 is a high insulating communication cable cross section structure sketch map in the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
As shown in Figure 1, be high insulating communication cable cross section structure sketch map in the utility model.High insulating communication cable comprises cable core, belting layer 3, reticulate pattern strips 4, aluminium strip 5, drain wire 6 and restrictive coating 7.Conductor 1 constitutes lead with insulating barrier 2, and 2 stranded formations of lead are to the line group, and at least 2 cable core coats belting layer 3, reticulate pattern strips 4, aluminium strip 5 and restrictive coating 7 outward successively to the stranded formation cable core of line group, vertically is provided with drain wire 6 between reticulate pattern strips 4 and the aluminium strip 5.
Conductor 1 is used the solid copper conductor for the single core or the multicore cable that meet the GB/T3956-2008 standard, and diameter is 0.5mm, and the material of insulating barrier 2 is a polyolefin, and the conductor 1 outer insulating barrier 2 that extrudes constitutes lead.Per 2 leads are twisted into one to the line group, and 400 to the stranded back of line group composition cable core; Cable core coats belting layer 3 outward, and belting layer 3 is by 4 layers of wrapped forming of polyester belt, and ground floor and the 3rd layer of employing clockwise direction are wrapped, and the second layer and the 4th layer of employing are wrapped counterclockwise; The wrapped 1 layer of corrugated reticulate pattern strips 4 in belting layer 3 outsides, reticulate pattern strips 4 outer aluminium strip 5 and the restrictive coatings 7 of coating are successively vertically placed 1 drain wire 6 between reticulate pattern strips 4 and the aluminium strip 5, and drain wire 6 is the tinned copper wire of 0.5mm for diameter.
The utility model adopts the multi-layered polyester band wrapped, and every layer of lapping direction difference guaranteed lapping; Simultaneously, outside belting layer, adopt the corrugated reticulate pattern strips wrapped, increased cable air content, improved the insulation property of telecommunication cable; Adopt the mode of aluminium strip outsourcing and cloth drain wire, guaranteed the shielding properties of cable.
