High Tensile Strength Galvanized Steel Strand For Catenary Wire

Quick Detail:

1, the surface of the steel strand of wire should not be folding marks, scratches, defects such as broken, crushed, and hard to bend.

2, steel strand surface must be free of oil, dirt, water and other impurities.

3, steel strand within split the galvanized layer of steel wire surface shall be uniformly continuous, no crack and spalling phenomena. But a few bright spots and white zinc layer surface thin layer and color difference.

Description:

1. Good soft

2. Good stability

3. good reliability

4. High strength

Galvanzied steel strand by cross section structure is divided into four size. As shown in the figure below. Structural steel strand section figure 1 x 3  1x 7  1 x 19  1 x 37

The winding process requirement inside the steel strand,

1,steel wire (including central wire) should be the same diameter, the same intensity, the same level of zinc layer.

2, the diameter of the steel strand and lay length should be uniform? Don't loose after cut off.

3, in the steel strand wire should be tightly twisted? Should not have staggered, fracture and bending.

4, steel wire should be flat, soft, small residual stress? There should not be a unfolds.

5, 1 x3 structural steel strand and overhead ground wire connection is not allowed in other types of steel strand wire welded butt joint application, any two joint spacing shall not be less than 50 m connector should be tested for corrosion resistance.

Applications:

Galvanized steel strand usually used in carrier cable (messenger wire), wire (guy wire), strengthen the core (core wire or strength member), etc., can also act as the ground plane overhead transmission (earth wire/ground wire), the block on both sides of the road (barrier cable) or the structure of the cable structure (structure cable). Structure of 1 x 7, specification of 5.4, 6.0, 6.6 and 9.0 of the galvanized steel wire can be used to post pole overhead wire.

Competitive Advantage:

1, steel strand wire (including central wire) should be the same diameter, the same intensity, the same level of zinc layer.

2, the diameter of the steel strand and lay length should be uniform? Don't loose after cut off.

3, in the steel strand wire should be tightly twisted? Should not have staggered, fracture and bending.

4, steel wire should be flat, soft, small residual stress? There should not be a unfolds.

5, 1 x3 structural steel strand and overhead ground wire connection is not allowed in other types of steel strand wire welded butt joint application, any two joint spacing shall not be less than 50 m connector should be tested for corrosion resistance.
