Abstract
The utility model discloses a DC cable resistant to salt spray and oil. The DC cable comprises two conductors which are prepared by twisting tin-coated soft copper wires. Twisting pitch diameter ratio is from 8 to 13. Alloy wires are disposed on the center of the two conductors. The two conductors are respectively wrapped in a semi-conductive shielding layer and an ethylene propylene rubber insulating layer by using extrusion molding technology in order to form an insulating wire core. The insulating wire cores are mutually twisted to form a beam in order to form a cable core wrapped in a wrapping tape layer. Waterproof yarn is disposed between the wrapping tape layer and the cable core in order to form a filling layer. Steel cores with rhombic cross sections are disposed in the filling layer. The steel cores are wrapped in silicone rubber insulating layers. The wrapping tape layer is wrapped in an oil-resistant flame-retardant irradiation elastomer sheath layer. The conductors are designed structures of tensile conductors and not only have good flexibility, but also have corrosion resistance and superior electrical performances. In addition, the cable has characteristics of good waterproof performance, flame-retardant performance, oil resistance, salt spray resistance, seawater corrosion resistance, low temperature resistance, and wear resistance.
Description
Technical field:
The utility model relates to direct current cables, relates in particular to a kind of salt spray resistance oil resistant direct current cables.
Background technology:
Along with the fast development of World Economics, people grow with each passing day to the demand of the energy, and the energy also strengthens the pollution of environment thereupon, have caused the concern that people use clean energy resource.A large amount of energy is wherein being contained as zone the most wide on the earth in the ocean, as wind energy, tidal energy, ocean current energy, geothermal energy etc.With a large amount of electrification transmission equipments, must need cable product in these occasions.And along with development of electric power industry, direct current cables is with its excellent characteristics, as: the transfer rate height, line loss is little; It is convenient to regulate electric current and change direction of transfer; Install, maintenance cost is low etc., used in increasing long river.
Marine environment requires equipment to have salt spray resistance because of its particularity, oil resistant, and performances such as seawater corrosion resistance also must possess same good victory energy with the suitable cable of its equipment so.Therefore, need design salt spray resistance oil resistant direct current cables.
The utility model content:
The utility model provides a kind of salt spray resistance oil resistant direct current cables, reasonable in design, and the tensile strength excellence has salt spray resistance oil resistant, sea water corrosion resistant, oil resistance is good, fire resistance is high advantage.
The technical solution of the utility model is as follows:
Salt spray resistance oil resistant direct current cables, comprise two conductors, it is characterized in that: described two conductors adopt zinc-plated soft copper skein silk to close and form, stranded lay ratio is 8 ~ 13 times, two conductor centers are provided with the alloy silk, two conductors outward respectively extrusion moulding semiconductive shielding layer is arranged, the ethylene-propylene rubber insulating barrier constitutes insulated wire cores, the mutual stranded bunchy of insulated wire cores constitutes cable core, cable core is provided with belting layer outward, be provided with water blocking yarn between belting layer and the cable core and constitute packed layer, be provided with the steel core that the cross section is a rhombus in the packed layer, steel core is coated with silicone rubber insulation layer, and belting layer is provided with the fire-retardant irradiation elastic body jacket of oil resistant layer outward.
Described salt spray resistance oil resistant direct current cables is characterized in that: described belting layer adopts the overlapping wrapped formation of environment-friendly halogen-free flame-proof band, puts up rate 〉=15%.
The utility model has the advantages that:
