Galvanized Wire For ACSR conductor

Galvanized Wire Strand is made to ASTM B498; ASTM A 475; BS 183 etc. The metallic zinc coatings applied by the galvanizing process are an effective way of combating corrosion in steel. Galvanized wire for cable application is available in a Class A coating; Class B coating and Class C coating.

Class A coatings are smoother, however less corrosion resistant than heavy galvanized coatings and are often used in normal wire working applications. Some typical end users include cages, bucket handles, coat hangers and baskets.

 

Class B and Class C coatings are used in conditions where atmospheric corrosion is severe. End users include crop support wires where chemicals are used, pool fencing or chain mesh in coastal areas.

Galvanised Wire Working Specifications

Given that galvanized wire is classified according to the amount of zinc coating, the following table outlines the difference between standard, heavy galvanized and extra-high galvanized wire.

 

Nominal Diameter	Minimum Coating Mass (g/m2)
	Class A	Class B	Class C
over 1.6 mm up to and incl. 1.90mm over 1.90mm up to and incl. 2.30mm over 2.30mm up to and incl. 2.70mm over 2.70mm up to and incl. 3.10mm over 3.10mm up to and incl. 3.50mm over 3.50mm up to and incl. 3.90mm	210 220 230 240 260 270	420 440 460 480 520 540	630 660 690 720 780 810

Tensile Strength (Mpa)

The tensile strength is defined as the maximum load achieved in the tensile test, divided by the cross-sectional area of the wire test piece. Galvanized Wire is produced using soft, medium and hard grade wires. The following table specifies the tensile range according to the grade:

 

Nominal Wire Diameter	Stress at 1% Elongation (Mpa)
	Class A	Class B	Class C	Extra-High
over 1.6 mm up to and incl. 2.30mm over 2.30mm up to and incl. 3.05mm over 3.05mm up to and incl. 3.60mm over 3.60mm up to and incl. 4.80mm	1310 1280 1240 1170	1240 1210 1170 1100	1170 1140 1100 1070	1560 1560 1560 1560
