Described insulating barrier adopts low smoke halogen-free fire retardant polyolefin cable material, described sheath adopts low-smoke and halogen-free flame retardant polyolefin jacket material, and add antioxidant and ultraviolet (UV) resistant agent therein, before the solar cables moulding cable core and insulating material are carried out preheating, to adopting gradually cold mode to cool off after the wire rod moulding, described insulating barrier (2) and sheath (1) all carry out crosslinking Treatment by radiation mode.
The utility model compared with the prior art, owing to adopt good insulating material, antioxidant, ultraviolet (UV) resistant agent have been added, crosslinking with radiation, preheating reaches technologies such as progressively cooling, makes cable design reasonable, long service life, have good low-temperature resistance, high temperature resistant, water-fast steam, anti-daylight, UV resistant, and fatigue durability, weather-resistant performance, anti-microbial performance, oil product, chemicals are had fabulous corrosion resistance; Simple in structure, be easy to processing and manufacturing, production cost is lower, and is safe and reliable, and can reach 25 years useful life, and burning can not produce toxic gas, and material itself is nontoxic, can not pollute environment.
Description of drawings
Fig. 1 is a schematic cross-section of the present utility model.
Among the figure: 1-sheath, 2-insulating barrier, 3-conductive monofilament, 4-cable core.
Embodiment
Understanding for the ease of those skilled in the art describes in further detail the utility model below in conjunction with the drawings and specific embodiments.Should be pointed out that specific embodiment described herein only is used to explain the utility model, and be not used in qualification the utility model.
Solar cables as shown in Figure 1 comprises cable core 4 and is coated on the outer insulating barrier 2 of cable core that described cable core 4 comprises that some are restrainted the conductive monofilament 3 that tangles and lump together each other, and described insulating barrier 2 peripheries also are with sheath 1, and conductive monofilament is adopted 3 and used tinned copper wire.
Described insulating barrier 2 adopts low smoke halogen-free fire retardant polyolefin cable material, and described sheath 1 adopts low-smoke and halogen-free flame retardant polyolefin jacket material, and adds antioxidant and ultraviolet (UV) resistant agent therein,
Described conductive monofilament 3 adopts tinned copper wire, and the purity of copper reaches 99.99%, and the employing of conductor meets the requirement that IEC60228 stipulates the 5th kind of conductor regulation.Copper wire is through specific lay bundle strand, and cable core surface, multiple strand back keeps the burr of bright and clean, no greasy dirt, not damaged insulation, and the monofilament of projection or fracture.
Sheath 1 adopts the low cigarette low-smoke and halogen-free flame retardant polyolefin jacket material of low temperature resistant, wear-resisting, ageing-resistant, anti-microbe, excellent anti-corrosion performance, and the resistance to low temperature of sheath can reach-50 ℃.
That described insulating barrier 2 adopts is low temperature resistant, corrosion-resistant, oil resistant, flame-proof elastomer material, and the resistance to low temperature of insulation can reach-50 ℃.
Before the described solar cables moulding cable core 4 is carried out preheating, at copper cash or conductor in the lining process, the utilization electromagnetic induction principle, make the usefulness of the continuous heating under the online motion of metallic conductor such as copper cash, with increase copper conductors with outward by between adhesive force, not enough in the solution electric wire course of processing because of adhesive force, and bad phenomenon such as generation conductor atrophy, and the generation of bubble and residual stress.
To adopting gradually cold mode to cool off behind the cable molding, promptly, cable is progressively cooled off with the gradually cold mode of hot water from 80 ℃ to 25 ℃.
Described insulating barrier 2 and sheath 1 all carry out crosslinking Treatment by radiation mode, evenly finish cross-linking process by the irradiation scanning of high-energy electron accelerator, make it form the crosslinked of network molecular structure.Make the long-term working temperature that allows bring up to 90 ℃ (or higher) by 70 ℃, the short circuit allowable temperature is brought up to 250 ℃ (or higher) by 140 ℃, under the prerequisite that keeps its original superior electrical performance, has improved actual serviceability widely.Do not add crosslinking agent in the cross-linking radiation CABLE MATERIALS, be effectively to penetrate insulating barrier when crosslinked by the high-power electron beam that high-energy electron accelerator produces, produce cross-linking reaction by power conversion, because electronics has very high energy, and pass insulating barrier equably, so the cross-bond that forms is in conjunction with energy height, good stability.
