ACSR Core Wire

The high-carbon galvanized steel wire or strands form the central core of the ACSR conductor (Aluminum Conductor Steel Reinforced), it supports and reinforces the cable conductor. The core steel can be a single wire or multiple strands of wire.

This product has good mechanical properties, thick zinc layer, smooth and firm, heavy plate, accurate sizing. This product is widely used for steel core wire in power line cable, ground electrode, stay wire.

Standards

According to ASTM B498; ASTM A 475; BS 183, We produce steel wire for ACSR, increasing the corrosion resistance of steel wire by galvanizing the surface. The zinc layer we can produce are Class A grade; Class B and Class C.
Class A zinc coatings have smooth surface but are less resistant to corrosion than Class B and C, and are used in general purpose applications. Class B and C zinc coatings are highly resistant to corrosion and can be used in wet and harsh environments such as coastal areas.
In addition, we can also produce zinc aluminum alloy coating products for customers to choose.
Single Wire Diameter Range： 1.57 -6.00 mm

Range of zinc coating:

Wire diameter	Minimum coating mass (g/m2)
Wire diameter	Standard zinc layer	Thick zinc layer	Super thick zinc layer
1.6 mm -1.90mm	210	420	630
1.90mm - 2.30mm	220	440	660
2.30mm - 2.70mm	230	460	690
2.70mm - 3.10mm	240	480	720
3.10mm - 3.50mm	260	520	780
3.50mm - 3.90mm	270	540	810

Tensile Strength (Mpa):

Tensile strength is used to specify the breaking force of steel wire, can be divided into three levels.

Wire diameter	Stress at 1% extension（Mpa)
Wire diameter	A	B	C
1.6 mm - 2.30mm	1310	1240	1170
2.30mm- 3.05mm	1280	1210	1140
3.05mm - 3.60mm	1240	1170	1100
3.60mm - 4.80mm	1170	1100	1070

Wire diameter	Tensile strength (Mpa)
Wire diameter	A	B	C
1.6 mm - 2.30mm	1450	1380	1310
2.30mm- 3.05mm	1410	1340	1280
3.05mm - 3.60mm	1410	1340	1280
3.60mm - 4.80mm	1380	1280	1240

Wire diameter	extension (%)
Wire diameter	Class A	Class B	Class C
1.6 mm - 2.30mm	3	3	3
2.30mm- 3.05mm	3.5	3	3
3.05mm - 3.60mm	4	3	3
3.60mm - 4.80mm	4	4	4

Chemical composition of steel

We have many kinds of steel base material to choose from, and the steel material can be treated with lead hardening to achieve different strengths. The following table shows the chemical composition of steel

Strength level	% C	% P	% Mn	% Si	%S
Standard	0.45~0.50	0.032	0.5 ~1.00	0.10~0.34	0.041
High	0.59~0.63	0.035	0.5 ~1.10	0.10~0.35	0.045
Extra-High	0.65~0.83	0.035	0.5 ~1.10	0.10~0.35	0.045
