armouring cable wire

Feature:mild steel,vertical hot-dipped galvanizing Tech.Thick zinc-coating,smooth surface,Stable mechanical electrical property

Function: Protecting cables from mechanical damage, preventing fire, enhanced cable tensile strength and mechanical strength, improving anti-corrosion ability, anti-role of low-frequency interference, etc.

Application: Power cable,phone cable,telecommunication cable and other general engineering applications

Features: Use mild steel,vertical hot-dipped galvanizing Technology

                Thick zinc-coating,smooth surface           

                Stable mechanical and electrical properties

Packing: Bundled tightly with 6 steel strips,plus 4 lifting hooks,put cardboard under each strip to prevent scratches,and covered 2-layer water-proof woven in outside, and also can packed according to customers' requirement.

The tensile strength,elongation rate and torsion test should comply to the following table:

Nominal dia. mm	Tensile strength Kgf/mm2	Elongation rate		Torsion test
		% Not less than	Gauge mm	Times not less than	Gauge mm
1.6 2.0 2.5 3.15 4.0 5.0 6.0	35-50	10	160 200 250 250 250 250 250	37 30 24 19 15 12 10	150

 zinc coating weight of steel wire,uniformity(copper sulfate solution),fastness(winding test)should conform to:

Nominal Dia. ( mm)	1					2
	Zinc coating weight g/m2 Not less than	The No. of immersed  in copper sulfate solution not less than		Winding test		Zinc coating weight g/m2 Not less than	The No. of immersed  in copper sulfate solution not less than		Winding test
				Dia. of cylindrical mandrel divided by nominal dia. of wire	No. of turns not less than				Dia. of cylindrical mandrel divided by nominal dia. of wire	No. of turns not less than
