Technical field
The present invention relates to a kind of cable, be specifically related to a kind of volume increasing and energy saving flame-proof power cable.
Technical background
Domestic city looped network transmission line generally adopts three-core structure, and laying installation is disposable to be completed, but between cable weak heat-dissipating, cable core, thermal resistance is large, and cable conductor resistance in conduct electrical power becomes large, and electric energy loss rolls up.If select conventional single cored structure, its good heat dissipation relatively improved 30% with its conductor ampacity of cross section three-core structure, but the cable laying workload is large, easily causes threephase load unbalanced.In conjunction with the pluses and minuses of three-core cable and single-core cable, a kind of easy for installation, cable that heat radiation is excellent not only can satisfy the consumption of saving copper, aluminum metal, can also reduce every waste in the cable production process.
Summary of the invention
The purpose of this invention is to provide and have excellent heat radiation, environmental protection, lay easy volume increasing and energy saving flame-proof power cable.
For achieving the above object, technical solution of the present invention is as follows:
The invention provides a kind of volume increasing and energy saving flame-proof power cable, comprise that its conductor is enclosed with conductor shield, insulating barrier, insulation screen, copper strips lapping layer, galvanized steel strip armour, flame retardant coating and restrictive coating outward successively.
Described conductor adopts electrician's circular copper wire or aluminium alloy strand system, aluminium alloy flexible in the large I of wiring space or electrician's circular copper wire.
Described insulating barrier adopts crosslinked polyethylene to extrude, and has higher insulation property and water proofing property.
Described conductor shield and insulation screen are extruded by semiconductive, can play uniform electric field, improve the high voltage withstanding performance of cable.
Described copper strips lapping layer can play uniform electric field, and can be used for ground protection, can avoid casualties in irresistible accident.
Described galvanized steel strip armour employing S type is two buckles sheathed structure, makes cable have excellent bearing capacity, also can bear stronger oblique pulling, and construction and installation are very convenient; And at cable copper strip lapping layer and the middle helical duct that forms hollow of galvanized steel strip armour, be conducive to the heat radiation of single-core cable, reduce electric energy loss.
Described flame retardant coating adopts double-deck synthetic mica tape wrapped, and its tensile strength is good, and fire line is high.
Described restrictive coating adopts electric cable material with low smoke and halogen free or thermoplastic polyurethane to extrude, and selects flexibly arbitrary material according to different operational environments.
The invention has the advantages that:
1, conductor adopts electrician's circular copper wire or aluminium alloy strand system, aluminium alloy flexible in the large I of wiring space or electrician's circular copper wire.
2, insulating barrier adopts crosslinked polyethylene to extrude, and has higher insulation property and water proofing property.
3, master core conductor shield and master core insulation screen are extruded by semiconductive, can play uniform electric field, improve the high voltage withstanding performance of cable.
4, the copper strips lapping layer adopts red copper (T2) copper content more than 99.9%, and elongation is greater than 30%, and tensile strength is greater than 200MPa.
5, galvanized steel strip armour employing S type is two buckles sheathed structure, makes cable have excellent bearing capacity, also can bear stronger oblique pulling, and construction and installation are very convenient; And at cable copper strip lapping layer and the middle helical duct that forms hollow of galvanized steel strip armour, be conducive to the heat radiation of single-core cable, reduce electric energy loss.
6, it is wrapped that flame retardant coating adopts double-deck synthetic mica tape, and its tensile strength is good, and fire line is high.
7, restrictive coating adopts electric cable material with low smoke and halogen free or thermoplastic polyurethane to extrude, and selects flexibly arbitrary material according to different operational environments.
