Our Cable Spark Tester (also named power frequency spark tester) is a specialized industrial testing device designed exclusively for insulation defect detection in wires and cables. As a critical quality control equipment for cable production, it adopts advanced inductive voltage regulation technology, featuring low electromagnetic interference, ultra-high detection sensitivity, excellent field adaptability, and reliable safety performance. This high voltage spark tester for wire and cable supports continuous operation mode, can be seamlessly linked with extruders and cable production lines, and complies with mainstream international and domestic industrial testing standards, making it an indispensable tool for industrial cable manufacturers to ensure product quality and compliance.
Our cable surface damage detection spark tester delivers industry-leading detection sensitivity of less than 600uA, with a transient breakdown current of 0.6mA, capable of capturing tiny insulation defects in real time during high-speed cable production. When insulation defects are detected, it triggers immediate audible and visual alarm and automatic shutdown, while accurately recording the number of breakdowns (0-999 counting range), realizing full-process traceable quality control.
Safety is the core design priority of our industrial cable spark testing equipment. It is equipped with a professional safety interlock system: when the electrode box protective cover is opened, the high voltage is automatically cut off, and the discharge needle grounds the high-voltage electrode to eliminate electric shock risks. Strict grounding design ensures stable operation, avoiding dangerous high voltage on the equipment casing or cable core, fully protecting the personal safety of on-site operators.
With an adjustable center height of 900-1100mm, this inline cable spark tester can flexibly adapt to cable production lines of different specifications. It supports a maximum detection speed of up to 420m/min, compatible with cable outer diameters from small sizes up to 40mm. The equipment adopts 5mm beaded chain electrodes, with customizable copper beads supported, and has a compact structure for easy installation and maintenance, suitable for long-term continuous operation in complex industrial environments.
