Abstract

The utility model provides a flexible resistant crooked fireproof cable of aluminum alloy conductor, including cable, filling layer, band, isolation layer, armor and outer jacket, wherein the conductor core of cable make for the aluminum alloy, the outside of conductor core is around a package mineral substance flame retardant coating, the outside cladding of flame retardant coating has the insulating layer, the many closely knit ranges of cable, by around the band around double -baging, around covering cladding isolation layer, armor and outer jacket in proper order outward, it has the filling layer to fill between covering and isolation layer, the advantage does: light in weight, the price is low, is about 70% of copper core cable price, and simple to operate is anti -oxidation, and long service life is economical and practical, and the user is satisfied.

Description

Aluminium alloy conductor flexibility resist bending fireproof cable

Technical field

This utility model is related to aluminum alloy conductor cable field, prevents more particularly, to a kind of aluminium alloy conductor flexibility resist bending Thermoelectricity cable.

Background technology

Due to China Copper resource shortage, output much can not meet demand, and needs are in a large number from external import and expensive, Manufacture cabling requirements amount is big, and Costco Wholesale is high.China's bauxite resource enriches, and traditional aluminium cable contact resistance is big, and oxidation is fast, makes With short life, therefore aluminium alloy conductor and aluminium alloy armored cable performance are good, long service life, and cable trouble free service is up to 40 Year, and it is economical and practical, the best selection of copper cable is that instead of, my company sets up research and development group, through the effort of half a year, buys New equipment, designs new technology, aluminium alloy conductor flexibility resist bending power cable.

The content of the invention

The purpose of this utility model is, to solve the deficiencies in the prior art, and to provide a kind of aluminium alloy conductor flexibility bending resistance Bent fireproof cable.

This utility model provides new technical scheme：Aluminium alloy conductor flexibility resist bending fireproof cable, including cable, fill out Fill layer, band, sealing coat, armor and outer jacket, the conductor cores of described cable are made up of aluminium alloy, conductor cores outside around Bag mineral fireprotection layer, the outside of fireprotection layer is coated with insulating barrier；The closely knit arrangement of many cables, by twining package tape around double-baging, around Coat sealing coat, armor and outer jacket outside covering successively, packed layer is filled between lapping layer and sealing coat.

Described conductor cores are drawn using 8000 series alloys bars, it is stranded, press, annealing forms.

Described insulating barrier adopts crosslinked polyethylene.

The twining package tape of described lapping layer is PE bands.

Described packed layer adopts polypropylene gasket for packing.

Described armor adopts 5000 series alloys steel band lock armos.

Described outer jacket is using polrvinyl chloride or low smoke halogen-free flame-retardant polyolefin extrusion molding.

The beneficial effects of the utility model are：Aluminum alloy conductor cable, is that instead of the preferable product of copper core cable conveying electric energy Product, lightweight, price is low, is 70% or so of copper core cable price, and easy for installation anti-oxidation, long service life is economical and practical, User is satisfied with, and the operation of cable will bring considerable economic benefit for the development of my company.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Wherein：1 is conductor cores, 2 is fireprotection layer, 3 is insulating barrier, 4 is packed layer, 5 is band, 6 is sealing coat, 7 is armour Dress layer, 8 are outer jacket.

Specific embodiment

This utility model is described further below in conjunction with the accompanying drawings.

Aluminium alloy conductor flexibility resist bending fireproof cable, including cable, packed layer 4, band 5, sealing coat 6, armor 7 and Outer jacket 8, the conductor cores 1 of described cable are made up of aluminium alloy, the wrapped mineral fireprotection layer 2 in outside of conductor cores 1, fireprotection layer 2 outside is coated with insulating barrier 3；The closely knit arrangement of many cables, by twining package tape 5 around double-baging, cladding isolation successively outside lapping layer Layer 6, armor 7 and outer jacket 8, are filled with packed layer 4 between lapping layer and sealing coat 6.

Described conductor cores 1 are drawn using 8000 series alloys bars, it is stranded, press, annealing forms.

Described insulating barrier 3 adopts crosslinked polyethylene.

The twining package tape 5 of described lapping layer is PE bands.

Described packed layer 4 adopts polypropylene gasket for packing.

Described armor 7 adopts 5000 series alloys steel band lock armos.

Described outer jacket 8 is using polrvinyl chloride or low smoke halogen-free flame-retardant polyolefin extrusion molding.

Cable manufacturing process flow chart：

Buying aluminium alloy rod → wire drawing → twisted wire → annealing → 2 → extruded insulation of wrapped mineral fireprotection layer → stranding is wrapped → lock armo → extrude sheath → spray printing mark → product inspection.
