Tracer Wire Quality Control: Our Inspection Process

Author: Jack     Publish Time: 2026-10-21      Origin: Site

We inspect CCS tracer wire from the bare conductor through insulation, finished marking and reel length, and document the results for each production batch.

AITE Cable manufactures solid copper-clad steel (CCS) tracer wire for underground utility locating. These photos show the checks and equipment used during production.

Discuss Testing Requirements

Conductor Electrical & Mechanical Insulation Finished Wire Inspection Records

CCS Conductor Checks

Conductor Diameter

We measure conductor diameter against the required AWG and construction.

Copper Adhesion & Seam Inspection

We perform torsion checks and examine the copper layer and seam, referring to applicable ASTM B910/B910M provisions.

Electrical & Mechanical Tests

Electrical Resistance

We measure the resistance of a conductor sample and record the result.

Break Load

We test conductor break load against the requirement for the specified wire grade and size.

Insulation & Finished Dimensions

Insulation Thickness & Concentricity

We use an optical measuring instrument to inspect the insulated cross-section.

Marking, Surface & Reel Length

Surface & Printed Marking

We check surface appearance and verify printed product identification.
