PROCESS | TO CHECK |
Rod Rolling stage | Tensile strength & elongation. |
Wire Drawing | Diameter and surface of Single Wire. Tensile Strength and Wrapping test on Aluminum wires. Wires and elongation on annealed copper wire. Resistance of the Wire |
Stranding | Electric Dimension of the Conductor, Lay ratio. Surface of the Conductor. Electric Resistance of the conductor |
Extrusion (Insulation) | Insulation thickness Eccentricity of the insulator Spark testing |
Laying up | Sequence of Cores Circularity of Cable Laid up diameter Direction of Lay. |
Inner Sheathing | Thickness. Diameter over sheath. |
Armouring | Number and size of armour wire/strip Lay/direction of lay. Uniformity and circularity of wires Diameter over armoring. |
Extrusion | Sheath thickness. |
(Outer Sheathing) | Concentricity and overall diameter of the cable & finish surface. Embossing. |
Annealing test (Copper) | Tensile test (Aluminum) | Wrapping test (Aluminum) |
Conductor Resistance tests | Test for armour wires | Test for thickness of insulation & sheath |
Physical test for insulation, sheath | File resistance test | Test for bleeding & blooming of pigments |
