Abstract
The utility model relates to a self-bearing computer cable, comprising a sheath and an electric cable core formed by a conductor, an insulating layer and a shielding layer in the sheath, which is characterized in that: the cable is provided with a reinforced core, which is parallel to the electric cable core and is arranged in the same sheathe together with the electric cable core. When laying the cable, cable bridges are no longer required to be arranged, and thus the cable is particularly suitable to be laid overhead individually in long range. The utility model has the advantages of simple and reasonable structure, easy manufacturing, low cost, outstanding electric and physical properties and chemical stability, good application performance, as well as less workload, lower labor intensity, better working efficiency, and less material consumption and cost.
Description
Technical field
The utility model relates to a kind of structure of self-bearing type computer cable, and the structure of the cable of certain load-bearing and tensile strength is particularly arranged, and belongs to the cable technology field.
Background technology
The computer cable that is called as " nerve " of automation is made huge contribution for human modernization, its good electric property, physical property, chemical stability, and therefore, this cable has obtained using widely.Computer cable is used for the large automatic control system mostly, as power plant, petroleum and petrochemical industry, unmanned substation etc., in these occasions because of environment and requirements of one's work, most of computer cable length is apart from setting up in the air, all adopted cable testing bridge to set up in the past, and only set up a small amount of cable on the part cable testing bridge, and cause the wasting of resources, and great in constructing amount.
The utility model content
The purpose of this utility model is exactly at existing computer cable above shortcomings, a kind of both had good electric property, physical property, chemical stability are provided, have self-supporting ability and tensile strength again, be fit to long separately apart from the self-bearing type computer cable of setting up in the air.
The purpose of this utility model is to realize like this, the self-bearing type computer cable comprises the electric cable core that is made of conductor, insulating barrier, screen in sheath and the sheath, it is characterized in that cable is provided with strengthening core, strengthening core is parallel with electric cable core, and strengthening core and electric cable core are arranged in the same sheath.
Described strengthening core is a zinc-coated wire, is arranged on the electric cable core outside, constitutes external strengthening core self-bearing type computer cable.
Described strengthening core is a zinc-coated wire, and wrapped protective layer on the zinc-coated wire is arranged in the electric cable core, constitutes built-in strengthening core self-bearing type computer cable.
Described screen is to meet the copper wire woven shield of GB9330-88 requirement or is to meet the copper strips lapped shielding layer that GB9330-88 requires.
Described conductor is to meet 1 class or the 2 class conductors of GB/T3956-1997 material or is 5 classes or the 6 class conductors that meet the GB/T3956-1997 material.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and serviceability is good.Conductor adopts and to meet the GB/T3956-1997 material, and cable is that rigid structure adopts 1 class or 2 class conductors, when cable such as soft junction structure with 5 classes or 6 class conductors.Insulation meets the requirement of the XLPE material of stipulating among the PVC that stipulates among GB9330-88 and the GB/T8815-2002 or the GB/T12706-2002.Copper wire braiding or the wrapped shielding of copper strips are adopted in shielding, and performance meets the requirement of GB9330-88.Strengthening core adopts zinc-coated wire, the cable that long distance is laid adopts high-carbon steel wire, diameter is thick, intensity is high, bearing capacity is big, high-carbon steel wire tensile strength 〉=1300Mpa, short distance is set up and is adopted low charcoal steel wire, diameter is little, intensity is low, bearing capacity is less demanding, flexible, mild steel wire tensile strength 〉=900Mpa, blemish such as zinc-coated wire any surface finish, no water stain, dezincify, ring shape.The protection sheath adopts polyvinyl chloride or low smoke and zero halogen material, and performance meets the regulation of GB9330-88 and relevant criterion.At needs cable testing bridge is not installed during this cable laying, independent length is especially used apart from cabling in the air, reduce workload, reduce labour intensity, increase work efficiency, economical with materials reduces cost.
