In automated factories and energy plants, signal crosstalk and insulation breakdown in multi-core cables cause 35% of control system failures, triggering production halts and safety risks. Shanghai Shenghua Power Group Cable solves these challenges with its 2-61 Core Unarmoured Control Cables, featuring XLPE thermal stability, EMI-resistant separation, and KEMA-certified reliability for 450/750V applications in cable trenches, PLC panels, and robotic arms.
Breakthrough Engineering for High-Density Signal Integrity
-
XLPE Insulation Superiority:
- Thermal Resilience: Withstands 160°C short-circuit temperatures (5 sec) and continuous 70°C operation—ideal for steel mill control panels near blast furnaces where ambient temps hit 65°C+
- Low Dielectric Loss: Insulation resistance up to 0.012 MΩ/km (2x0.75mm²) minimizes signal leakage by 40% versus standard PVC cables in humid environments
- Thermal Resilience: Withstands 160°C short-circuit temperatures (5 sec) and continuous 70°C operation—ideal for steel mill control panels near blast furnaces where ambient temps hit 65°C+

High-Core Precision:
- 61-Core Separation Technology: Individual XLPE insulation prevents cross-talk in multi-axis CNC machines, even when transmitting 10A power and 1kHz sensor signals simultaneously
- Compact 6× Bend Radius: Slim profiles (e.g., 8.1mm OD for 2x0.75mm²) enable routing through robotic wrist joints, surviving 250,000+ flex cycles without conductor fatigue
- 61-Core Separation Technology: Individual XLPE insulation prevents cross-talk in multi-axis CNC machines, even when transmitting 10A power and 1kHz sensor signals simultaneously
