Why Spark Testing Matters

Spark testing is a critical non-destructive method used to verify the integrity of insulation or sheathing on electrical cables and wires. By applying a high-voltage electrical field, spark testers quickly detect defects such as pinholes, cracks, or weak spots in real-time. If a fault is detected, the system triggers an automatic alert, allowing immediate corrective action and helping manufacturers comply with international safety standards and customer quality expectations.

A Natural Fit

As a specialist in non-contact measurement and process control, Control Metrix already supports many cable and wire producers with laser micrometers, diameter and ovality gauges, lump and neck flaw detection and length measurement systems. The addition of Clinton’s spark testing equipment enhances our ability to provide complete quality assurance solutions for the cable industry – helping you reduce waste, avoid compliance issues, and ensure product reliability.
