These instruments are a critical part of any <strong>wire extrusion quality control<\/strong> process, ensuring that insulation and jacket layers are free of defects before the cable leaves the production line. We source units compatible with equipment from leading manufacturers such as <strong>Troester, Maillefer, Rosendahl, Nextrom<\/strong>,\u00a0and many others.<\/p>\n<p>A <strong>spark tester<\/strong> \u2014 also known as a <strong>holiday tester<\/strong>, <strong>pinhole detector<\/strong>, or <strong>high-voltage spark tester<\/strong> \u2014 applies a controlled high-voltage electrical field around the cable as it passes through the electrode. Any defect in the insulation, such as a <strong>pinhole, void, crack, thin wall, or contamination<\/strong>, causes an electrical discharge that is immediately detected and logged. This process is essential for compliance with international standards including <strong>IEC 60227, IEC 60245, IEC 60502, UL 44, UL 83, VDE 0281,<\/strong> and <strong>VDE 0282<\/strong>.<\/p>\n<p>We offer <strong>spark testers<\/strong> in a wide range of configurations, covering test voltages typically from <strong>1 kV up to 50 kV DC or AC<\/strong>, depending on the insulation type and wall thickness. Compatible insulation materials include <strong>PVC, polyethylene (PE), cross-linked polyethylene (XLPE), EPR, silicone rubber, TPE, TPU<\/strong>, and specialty compounds used in <strong>automotive, aerospace, marine, and industrial cable<\/strong> applications. Electrode designs are available in bead chain, spring contact, and water trough configurations to suit different cable diameters and line setups.<\/p>\n<p>All units and spare components are available with <strong>worldwide shipping<\/strong> and full technical support. Whether you need a complete <strong>spark tester unit<\/strong>, a replacement <strong>high-voltage electrode<\/strong>, a <strong>control unit<\/strong>, or individual components such as cables,
