A kind of cable adopting the steel band of modified node method
The application is that name is called: a kind of steel band of modified node method and use the cable of this steel band, the applying date is: the divisional application of the patent of invention of on 06 26th, 2014, application number is: 201410292203.2.
Technical field
The invention belongs to cable material and technical field of cables, especially relate to a kind of steel band of modified node method and adopt the cable of this steel band.
Background technology
Steel band is as the armouring element in cable, and be usually longitudinally be coated on outside cable core, certainly, described cable core can be inner sheath etc.; As shown in Figures 1 and 2, steel band is made up of base band 2, the first coating layer 1 covering base band upper surface, the second coating layer 3 of covering base band lower surface usually, and the cross section of the base band of steel band is rectangle, and first, second coating layer is also rectangle; When producing cable, be longitudinally coated on cable core by steel band, the left side 5 that the right side 4 of steel band crimped or be bonded in steel band forms overlap joint, and the width of overlap joint must meet the requirement of industry standard, at the outer coated sheath 6 of extrusion molding of steel band; The width of overlap joint is limited, mainly in order to cable is produced convenience, cable torsion or bending time do not produce the cracking of sheath.
But, the thickness of steel band of the prior art is substantially identical, therefore the lap-joint of steel band can be obviously thickening in cable, cable often has requirement for the minimum thickness of sheath, like this, in order to meet the minimum value requirement of jacket thickness, usually diameter increase about about the 0.5mm of cable can be made, the sheath of about 0.5mm means different sheath material consumptions for the cable of different-diameter, such as diameter is that the cable of 10mm adopts HDPE to process sheath and uses LSZH to process sheath, then need respectively to increase about 90 yuan/sheath kilometer and 220 yuan/sheath kilometer; And for example diameter is the cable employing HDPE processing sheath of 20mm and uses LSZH to process sheath, then need respectively to increase about 175 yuan/sheath kilometer and 430 yuan/sheath kilometer; And for example diameter is the cable employing HDPE processing sheath of 30mm and uses LSZH to process sheath, then need respectively to increase about 260 yuan/sheath kilometer and 640 yuan/sheath kilometer; And for example diameter is the cable employing HDPE processing sheath of 40mm and uses LSZH to process sheath, then need respectively to increase about 350 yuan/sheath kilometer and 850 yuan/sheath kilometer; For another example diameter is the cable employing HDPE processing sheath of 80mm and uses LSZH to process sheath, then need respectively to increase about 700 yuan/sheath kilometer and 1700 yuan/sheath kilometer.China advocates low-carbon environment-friendly, resources conservation, but, as foregoing description, in line cable industry, cause the significant wastage of sheath material, and, outer diameter of cable do thick after, need the pipeline that takies or space resources is more, freight is more etc., very uneconomical.
