SP Series Spark Tester is a high-precision defect inspection device specially designed for wire extrusion production lines. By applying a stable high-voltage electric field in the gap between the electrode and cable, it accurately identifies pinhole and bare conductor defects.
The equipment supports continuously adjustable voltage over a wide range from 0.5kV to 15kV, stably compatible with various cables including power cables, automotive wires and data cables with outer diameter within 30mm. Integrated with key functions such as automatic shutdown protection, real-time voltage monitoring and safety interlock, it effectively prevents wire burn damage and ensures operational safety, providing reliable assurance for the goal of "zero defects" in cable manufacturing.
The SP Series Spark Tester is a high-end in-line cable inspection device integrating high-precision detection, flexible operation, safety, reliability and easy integration. Its core value lies in guaranteeing cable product quality. With comprehensive safety design and abundant interfaces, it delivers stable, intelligent solutions that meet stringent safety standards for modern high-speed production lines.

Answers to frequently asked questions about Spark Tester（SP Series）
More Communication Interfaces
Equipped with RS485, Bluetooth, Wi-Fi, and Industrial Ethernet. Many domestic products support only two communication interfaces.
C3 Touchscreen with More Functions
Supports voltage adjustment, 2-level sensitivity, defect resolution settings, and automatic classification of pinhole and bare-wire defects. It also displays defect count, defect position, line speed, voltage calibration, and user access levels. Many domestic products use only buttons and digital displays, showing mainly voltage and defect count.
Customizable I/O Signals
Supports 8 categories of digital inputs and outputs, configurable for functions such as high-voltage start/stop, defect reset, defect limit alarms, and equipment fault alarms. Output duration and frequency can also be customized.
Bluetooth Remote Control by Mobile Phone
All C3 touchscreen functions can be operated remotely via Bluetooth on a mobile phone.
Adjustable Time Resolution
Time resolution can be adjusted from 1 ms to 2 s. Higher time resolution helps reduce missed defects, while many domestic products do not offer this adjustment.
No. A spark tester cannot replace withstand voltage or insulation resistance testing.
Spark testing is mainly used for fast in-line screening to detect physical insulation defects such as pinholes or breaks. By contrast, withstand voltage and insulation resistance tests apply voltage for a longer period and are used to evaluate the cable’s overall insulation performance, breakdown resistance, and material quality before final delivery.
