Summary of the invention
The utility model object is to provide a kind of communication distributed intelligent monitoring flexible cable, this communication distributed intelligent monitoring flexible cable effectively raises the flexibility of outside cable, ensure the strain of cable tensionless winkler foundation, both improve tensile strength, also there is the effect disperseing and cushion extraneous stress, its better mechanical property.
For achieving the above object, the technical solution adopted in the utility model is: a kind of communication distributed intelligent monitoring flexible cable, comprise: four heart yearns, this heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, one inner insulating layer is coated on described heart yearn outer surface, one polyester belt is wrapped in described four heart yearn outer surfaces, some polyethylene fibres are arranged at polyester belt outer surface abreast thus form high-modulus polyethylene fibres layer, and an oversheath insulating barrier is coated on described high-modulus polyethylene fibres layer outer surface; Have some root polypropylene gasket for packings between described polyester belt and four heart yearns, this polypropylene gasket for packing to be circumferentially spacedly distributed at least 4 lug bosses at its outer surface.
In technique scheme, further improvement project is as follows:
1., in such scheme, described copper conductor diameter is 0.15 ~ 0.17mm.
2., in such scheme, described polyethylene fibre diameter is 0.1 ~ 0.12mm.
3., in such scheme, the number of the lug boss of described polypropylene gasket for packing outer surface is 5.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model communication distributed intelligent monitoring flexible cable, its transmission characteristic can meet its transmission requirement, because cable have employed the stranded conductor of multiply tin-coated copper single line, effectively raises the flexibility of outside cable, simultaneously owing to arranging with adopting the PE fiber uniform parallel of high-modulus between cable core and outer jacket, and heart yearn is made up of the polyethylene strip and stranded 6 copper conductors in polyethylene strip outer surface being positioned at center, ensure the strain of cable tensionless winkler foundation, form the overcoat with desirable stretch-proof bending resistance, reduce the external diameter of cable greatly, facilitate laying and the problem of emergency maintenance of cable, improve maintenance efficiency and repair quality, stretch-proof bend-resistant electric cable had both had the strain of guarantee cable tensionless winkler foundation, guarantee that its transmission characteristic is steady in a long-term, have again lightweight, external diameter is little, pliability is good, the advantages such as price is low, there is obvious economic benefit and promotional value, secondly, its polypropylene gasket for packing to be circumferentially spacedly distributed at least 4 lug bosses at its outer surface, both improves tensile strength, also has dispersion and cushions the effect of extraneous stress, its better mechanical property.
