Stranded conductor

Large bearing ground shaft

This machine is suitable for the manufacture of copper and copper stranded wire, aluminum, aluminum alloy, steel core aluminum stranded wire, and the equipment production efficiency is high.

Separate motor

Each stranded cage is driven separately by a motor, which is independently controlled by the motor, and the speed is adjusted separately, through the gear;

Axis

This machine mainly supplies the wire cable factory to twist large-section aluminum stranded wire, steel core aluminum stranded wire, copper stranded wire and insulated wire strand. It is suitable for the production of large length bare aluminum and bare copper wire twisting and pressing.

Galvanized steel strands for high-strength bridge mining

Steel strands can be divided into four levels according to the nominal compressive strength: 1 270 MPa.1 370 MPa, 1 470 MPa and 1 570 MPa. According to the inner steel wire zinc layer can be divided into three levels: special A, A, B Steel strand raw material selection: carefully selected raw materials, carefully built, use with peace of mind. Processing customization: sample processing customization can be carried out according to customer requirements. Sufficient inventory: manufacturer production, quality assurance, sufficient inventory, rest assured to buy. The steel strand has strict requirements for the surface of the steel wire, and the surface of the steel wire cannot have damage such as stacking, breaking, scratching, bending and flattening. The surface of the steel strand can also not have oil stains and other impurities, and the galvanized layer on the surface should be uniform and continuous, without cracks and peeling.

Stranded wire for cable production process

1. Good flexibility: it can reduce the damage caused by bending, vibration and swinging, which is conducive to installation. 2. Good reliability: the defects of the single wire that make up the stranded wire cannot be concentrated in the same place, so the impact of the single wire defect on the performance of the stranded wire is much weaker than that on the performance of the single conductor. 3. High strength: When using the same rod wire, the drawn thin wire is deformed more than the thick line, so the strength of the fine line is high. The strength of the stranded wire is higher than that of a single conductor of the same section.

The cause and treatment of broken wire of steel strand

The general causes of broken wire of steel strands are: uneven steel strand material or serious corrosion; The steel strand contacts the welding spark or the welding machine wire, and the mechanical properties change; Serious crossover of steel strands near the anchor hole; The anchor deviates from the anchor pad stop point, the middle of the steel strand, or the end of the horn tube has a large bending angle with the bellows, resulting in the stress concentration of individual steel wires; The hardness of the sandwich does not match the steel strand; The tensioner is not checked as required, or the oil pressure gauge is faulty, resulting in excessive tension.
