In the wire and cable manufacturing and quality control industries, accurate measurement of DC resistance is fundamental to ensuring product performance, compliance, and material efficiency. The Intelligent Digital Electrical Bridge is a modern, high-precision conductor resistance testing instrument designed as an advanced upgrade to traditional bridge methods. It fully meets the technical requirements of IEC 60468 (formerly referenced as IEC 468) and the Chinese national standard GB/T 3048.4-2007, while offering the added capability of online (in-line) testing directly on the production line.
This digital bridge combines high-resolution measurement technology with intelligent automation, delivering fast, reliable, and repeatable DC resistance data for conductors, cables, and wires.
Applications principales
Designed specifically for the cable industry, the Intelligent Digital Electrical Bridge excels in:
- Wire and cable production lines – real-time monitoring of copper, aluminum, and alloy conductors during stranding and extrusion.
- Quality control laboratories – incoming raw material inspection and finished cable verification.
- Incoming inspection of electrical wires, power cables, and connectors.
- Online (in-line) testing during cable extrusion, stranding, and jacketing processes.
- R&D of next-generation conductor materials – supporting innovation with accurate data logging.
Its seamless online testing capability enables continuous production monitoring without workflow interruption, helping cable plants reduce material waste by up to 15-20% through early defect detection (based on industry benchmarks).
Compliance with International and National Standards
The instrument is developed in strict accordance with:
- IEC 60468 — International standard for DC resistance measurement of conductors.
- GB/T 3048.4-2007 — Chinese national standard for electrical conductor resistance testing.
These standards ensure the bridge provides traceable, high-accuracy results that meet global certification requirements for cable and wire products.
