ResTest 8135: Advanced Measurement System for Aluminum and Copper Conductors

Overview:

The ResTest 8135 is a state-of-the-art system designed to address the challenges of measuring aluminum conductors. By offering precise, non-destructive measurement capabilities directly on the stranding machine, the system enables manufacturers to reduce unnecessary excess material, saving both raw materials and production costs.

Key Features:

  1. Optimized for Aluminum Conductors:
    • Specifically tailored to handle the challenges of measuring aluminum, including high pressure requirements and conductor compaction.
  2. Material and Production Cost Savings:
    • Reduces unnecessary and expensive excess material margins (typically 2–5%) in cable production.
    • Eliminates scrap generation, enabling immediate testing and adjustments on the production line.
  3. On-Line Measurement Capabilities:
    • Directly measures conductors on the stranding machine without cutting samples for lab testing.
    • Provides rapid feedback for production adjustments, minimizing downtime.
  4. Innovative and Safe Design:
    • Patented Measuring Method: Allows precise results without costly or risky modifications like insulating the pull-off capstan and winding spool.
    • Hydraulic System with Adapted Jaw Shells: Ensures uniform current distribution without damaging the conductor.
  5. Dry Heating System for Rapid Temperature Stabilization:
    • Drastically reduces the time needed to stabilize conductor temperature.
    • No coolant or water required, streamlining the process.
  6. Overall Accuracy:
    • Offers unmatched reliability, with specifications covering the entire measurement process, not just the instrument itself.

Benefits:

  • Significant Savings: Optimizes material usage, leading to a payback period of less than a year.
  • Speed and Efficiency: Enables quick testing and rapid adjustments, boosting productivity.
  • Reliability and Safety: Ensures accurate measurements without damaging the conductor or requiring hazardous modifications.

The ResTest 8135 is an indispensable tool for manufacturers seeking to optimize cable production, reduce waste, and ensure the highest standards of accuracy and efficiency.
