Quality testing

Inspection equipment and testing items.

Review the testing equipment and control points used for conductor, insulation, material and finished-cable inspection.

Conductor resistance testing

Measure the DC resistance of cable conductors and assess electrical conductivity.

Use a controlled water-bath environment for insulation and electrical-performance checks.

Inspect conductor diameter, insulation thickness and concentricity with optical measurement.

Evaluate material heat resistance and ageing performance under controlled temperature.

Test the mechanical performance of conductors, insulation and sheath materials.

Measure insulation and sheath cross-section thickness for dimensional control.
