Component Specifications

Definition
Terminal connections in induction heating coils are specialized electrical interfaces designed to establish reliable, high-current connections between the coil windings and external power supply systems. These components ensure efficient energy transfer while maintaining structural integrity under thermal and mechanical stresses during induction heating operations.
Working Principle
Terminal connections function by providing low-resistance electrical pathways through conductive materials with optimized contact surfaces. They maintain stable connections despite thermal expansion/contraction cycles, using clamping mechanisms, threaded fasteners, or compression fittings to ensure consistent electrical conductivity throughout heating cycles.
Materials
High-conductivity copper alloys (C10100, C11000), copper-silver alloys, or aluminum alloys with silver or tin plating for corrosion resistance and enhanced conductivity. Insulation materials include ceramic, high-temperature polymers, or mica-based composites.
Technical Parameters
  • Current Rating 100-5000A
  • Voltage Rating 50-1000V
  • Connection Type Threaded stud, clamp, or compression
  • Insulation Class Class H (180°C) or higher
  • Temperature Range -40°C to 300°C
  • Contact Resistance <0.5 mΩ
Standards
ISO 5828, DIN 43673, IEC 60947-1
