CABLE TESTING & INSPECTION

Match Every Inspection Point to the Cable and Standard

Testing is planned from the approved model, voltage, construction and project specification. Not every test applies to every cable.

INSPECTION PLAN

Quality Control Across the Order

Incoming, in-process and final checks should be linked to the approved construction and acceptance criteria.

01 · INCOMINGMaterial ReviewReview conductor and compound information required by the approved order.
02 · IN-PROCESSConstruction ChecksMonitor dimensions, identification and applicable process checks during manufacturing.
03 · FINALFinished Cable TestsComplete required electrical, dimensional and visual inspection before release.
04 · DOCUMENTOrder RecordsVerify marking, length, packing and agreed inspection documents.
TESTING SCOPE

Typical Checks by Purpose

The actual method and acceptance criteria come from the applicable product or material standard.

Copper conductor processing for cable conductor quality control

CONDUCTOR

Conductor Checks

Material, wire diameter, strand construction and conductor resistance are reviewed against the ordered specification.

Cable sample inspection in the Lulian Cable quality area

DIMENSIONS

Construction and Dimensions

Core count, insulation thickness, sheath thickness and overall diameter may be checked as applicable.

Power-frequency spark testing during cable insulation production

IN-PROCESS

Spark Testing

Applicable in-process spark testing helps identify insulation defects before the next production stage.

Production operator checking cable manufacturing equipment

ELECTRICAL

Electrical Verification

Depending on the cable, checks may include continuity, conductor resistance, insulation resistance or voltage withstand.

Finished cable cross sections prepared for construction comparison

CONSTRUCTION

Finished Cable Review

Cross-section, layer sequence, material identification and finished appearance are compared with the approved design.

Armored power cable packed on a wooden drum for final inspection

FINAL RELEASE

Length, Marking and Packing

Printed marking, cable length, labels, drum condition and shipment information are checked before release.

BUYER REVIEW

Agree the Required Evidence Before Production

Third-party inspection, witness points and additional reports can affect price and lead time, so they should be included in the enquiry.

  • Applicable standard and cable datasheet
  • Routine, sample or project-specific tests
  • Inspection witness or hold points
  • Required report format and language
  • Third-party inspection requirements
