Abstract
The utility model discloses an organosilane crosslinked polyethylene-insulated and polrvinyl chloride-sheathed power cable which comprises four conductors, wherein each conductor consists of a plurality of refine-stranded or bunch-stranded thin copper wires with the diameters of 0.18-0.60mm, the conductors are 1/4 cylinder-shaped after being stranded into a bundle, the four conductors are respectively, externally and sequentially packed with a fire-resistant layer and an insulating layer, the four conductors packed with the insulating layers are arranged at each side of a cross-shaped support frame formed by the extrusion molding of tear-resistant silicon rubber to be formed into a cable core, each support foot end of the cross-shaped support frame is provided with an opposite-stranded phosphureted steel wire, and the cable core is externally and sequentially packed with a fire-resistant layer, an inner sheath layer, a shielding layer and an outer sheath layer which are wrapped by polyurethane belts in an overlapping way. According to the organosilane crosslinked polyethylene-insulated and polrvinyl chloride-sheathed power cable, the structures of the conductors are respectively designed to be 1/4 cylinder-shaped, and the conductors are distributed at each area of the cross-shaped support frame and are matched with the phosphureted steel wires, so that the compactedness and mechanical property of the power cable structure can be improved; and due to the fire-resistant layer and the protective layer of the power cable, the fire resistance of the power cable can be improved, and the power cable is further good in shielding property.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of organosilane crosslinked polyethylene insulation and polyvinyl chloride boot power cable.
Background technology:
Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.The main feature of fire safe type power cable is cable except transferring electric power in normal working conditions, cable still can keep the normal operation of certain hour when ignition, be applicable to the places relevant with fire safety and fire-extinguishing and lifesaving such as nuclear power station, subway, tunnel, skyscraper.
Ac rated voltage is at the power cable of 6kv ~ 10kv, and general maximum operating temperature is at 90 ℃, and minimum ambient temperature requires: fixedly lay temperature at-5 ℃, on-fixed lays 0 ℃ of temperature.Original this class cable is bad mechanical property in actual use, and disconnected core phenomenon easily occurs; Fire-resistance property is relatively relatively poor, and burning produces pernicious gas, and environment and human body are worked the mischief, and it is unobstructed to affect normal information transmission, causes huge economy damage.
The utility model content:
In order to remedy the defective of prior art, the purpose of this utility model provides a kind of organosilane crosslinked polyethylene insulation and polyvinyl chloride boot power cable, reasonable in design has good electric property and chemical stability, and mechanical performance and fire resistance are promoted significantly.
The technical solution of the utility model is as follows:
Organosilane crosslinked polyethylene insulation and polyvinyl chloride boot power cable, comprise four conductors, it is characterized in that: it is that the smart strand of 0.18 ~ 0.60mm thin copper wire or bundle strand consist of that described four conductors all adopt many root diameters, become 1/4 cylinder shape behind the stranded bunchy, four conductors all are enclosed with flame retardant coating outward successively, insulating barrier, four conductors of wrap insulate layer are positioned over each side formation cable core of cross supporting frame that tear-proof silicon rubber is extruded into, each leg end portions of cross supporting frame is provided with the phosphatization steel wire of pair twist, the phosphatization steel wire diameter is not less than 1.5mm, and cable core is enclosed with the overlapping wrapped fireprotection layer of polyurethane tape outward successively, inner restrictive coating, screen, external sheath layer.
Described organosilane crosslinked polyethylene insulation and polyvinyl chloride boot power cable is characterized in that: described insulating barrier adopts organosilane crosslinked polyethylene, and inner restrictive coating, external sheath layer adopt polyvinyl chloride.
The utility model has the advantages that:
The utility model structural design is novel, and it is 1/4 cylindrical that conductor structure is designed to, and is distributed in the cross supporting frame regional, cooperates the phosphatization steel wire, not only improved construction of cable compactedness, mechanical performance, protected well the cable core of cable; The flame retardant coating of this outer cable and the design of overcoat have improved the fire resistance of cable; In addition, cable also has good shielding properties, so that electric power transfer stability is protected.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
