2Scope in stranded 30 soft copper monofilament are arranged, its soft copper filament diameter is 0.25mm, the strand pitch than usually 20-23 doubly about, wrapped material is the PP band, insulation and sheath are to make base-material with natural gum, assist doping and make through traditional steam vulcanization (cure) is crosslinked.This cable conductor flexibility is not enough, is not easy to be used in mobile occasion; Temperature resistant grade low (about 65 degree); Cable machinery performance and fire resistance are low, under such environmental effects such as wind and rain, sunlight (ultraviolet ray), heat, ozone, will wear out behind the general 3-4, and useful life is short; And steam vulcanization (cure) causes the conductor oxidation easily; And need special rubber extruding machine and vulcanizing equipment; And air is dirty during mixing of rubber, and production environment is abominable, and it is healthy to influence the workman.
(3) summary of the invention: the purpose of this utility model will address the above problem exactly, provides that a kind of flexibility is good, temperature resistant grade is high, long service life, and production technology is simple, the insulation Plastic-sheathed Cable that production environment is good.
Concrete scheme of the present utility model is: a kind of insulation Plastic-sheathed Cable, have two strands of soft copper monofilament stranded conductors, it is characterized in that: per share soft copper monofilament stranded conductor coats the cross-linking radiation second third rubber sheath insulated layer outward, the outside stranding of two strand insulation layers is surrounded with the wrapped belt of polyester, and wrapped belt is coated with elastomer cable irradiation material restrictive coating.
Soft copper monofilament stranded conductor described in the utility model is 1.5mm in the cross section
2Scope in stranded 75 soft copper monofilament are arranged, its soft copper filament diameter is 0.16mm, pitch is than being 24-26.
The cross-linking radiation second third rubber sheath insulated layer thickness described in the utility model is: 0.8mm, the wrapped belt external diameter of polyester is: 6.6 ± 0.5mm, elastomer cable irradiation material restrictive coating external diameter is: 8.6 ± 0.5mm.
The utility model is 1.5mm owing to conductor structure is designed to the cross section
2Scope in stranded 75 soft copper monofilament are arranged, its soft copper filament diameter is 0.16mm, the pitch ratio is about 25 times, radical increases, filament diameter reduces, pitch is than strengthening, thereby increased the flexibility of conductor, is convenient to product to be used in mobile occasion; Insulating barrier adopts the cross-linking radiation ethylene-propylene rubber material of superior performance, restrictive coating adopts elastomer cable irradiation material, do not need special rubber extruding machine and vulcanizing equipment, and insulating barrier and restrictive coating are carried out the cross-linking radiation processing with electron accelerator, make plastic body become the network structure that links to each other layer by layer, thereby greatly improved the combination property of cable product by chain structure.
The utility model has the advantages that:
1. temperature resistant grade is brought up to 105 degree from 65 degree, and under identical service condition, the raising of its temperature resistant grade makes cable have long service life, current capacity is strong, safe, operating cost is low characteristics;
2. have better mechanical performance, tensile strength is improved;
3. have performances such as good weather, cold-resistant, oil resistant, acid and alkali-resistance, anti-ozone, have wideer use occasion and longer useful life;
4. production technology is simple, and production cost is low;
5. production environment is good, and the dirty phenomenon of the air when having avoided mixing of rubber helps protecting that environment and protection workman's is healthy;
6. the conductor problem of oxidation is fully solved.
(4) description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A zoomed-in view of Fig. 1.
Among the figure: 1-conductor, 2-insulating barrier, the wrapped belt of 3-, 4-restrictive coating.
(5) embodiment:
Referring to Fig. 1, Fig. 2, the utlity model has two strands of soft copper monofilament stranded conductors 1, particularly: per share conductor 1 is to be 1.5mm in the cross section
