Detailed description of the invention
Name preferred embodiment, and combine accompanying drawing and become apparent from intactly illustrating the present invention.
As it is shown in figure 1, a kind of armored cable, it includes band 5, three conductor wire cores 1 of being located in band 5 and three ground connection cores 3, and each conductor wire core 1 is all coated with core insulating barrier 2, is filled with flame retardant filler 4 in band 5；The outside of band 5 is coated with aluminium alloy armored layer 6, and the surface of aluminium alloy armored layer 6 is provided with lines (not showing on figure)；The outside of aluminium alloy armored layer 6 is coated with restrictive coating 7.The material of core insulating barrier 2 is crosslinked polyethylene；The material of restrictive coating 7 is polrvinyl chloride；The material of aluminium alloy armored layer 6 is the aluminium alloy of the trade mark 3003.
A kind of manufacture method of armored cable, it is used for manufacturing foregoing armored cable, and it comprises the following steps:
Step 1, three conductor wire cores of manufacture, each conductor wire core is closed by some annealed copper skein silks and presses into, covering thread core insulation layer on each conductor wire core.The material of core insulating barrier is crosslinked polyethylene (XLPE), and crosslinked polyethylene has good fire retardant insulating performance.
Three ground connection cores are set outside step 2, online core insulation layer, between online core insulation layer and ground connection core, fill flame retardant filler, the then outside cladding band of online core insulation layer, ground connection core and flame retardant filler.Flame retardant filler can use existing common material.By arranging flame retardant filler and employing has the band of fire resistance, both improve the fire resistance that cable is overall, and cable conductor rounding can have been made again, create conditions for next operation.
Step 3, being wrapped in vertical for aluminum alloy strip outside band, the material of aluminum alloy strip is the aluminium alloy of the trade mark 3003；At argon and the mixed gas protected lower of helium, aluminum alloy strip being carried out argon arc welding, wherein the volume ratio of argon and helium is 4:6；Then by water, aluminum alloy strip is cooled down, on aluminum alloy strip, then roll lines, thus form surface band textured aluminium alloy armored layer.
Step 4, at aluminium alloy armored layer outer cladding restrictive coating.The material of restrictive coating is polrvinyl chloride (PVC), and pvc sheath layer has good fire-retardant and protective value.
Use the power cable that such scheme is made, with U.S. UL (UnderwriterLaboratoriesInc., American insurance business tests institute) standard of certification tests, specifically with UL1569 standard (Metal-CladCable, metallic cover cable) and UL2225 standard (WireandCableTestMethods, electric wire test method) to test, its performance indications are specific as follows:
