Component Specifications

Definition
A specialized electrical insulation component designed to withstand high voltage differentials in transformers and inverters, preventing electrical discharge, arcing, and current leakage between conductive parts. It maintains dielectric strength under operational stresses including thermal cycling, mechanical vibration, and environmental exposure.
Working Principle
Operates by providing a high-resistance barrier between conductors at different electrical potentials, using dielectric materials to contain electric fields and prevent breakdown. It manages capacitive coupling and dissipates partial discharge energy to maintain insulation integrity.
Materials
Typically composed of epoxy resin composites, silicone rubber, porcelain, or glass-reinforced polymers with additives for tracking resistance, thermal stability up to 180°C, and hydrophobic properties. May include mica paper or aramid fiber layers for enhanced dielectric strength.
Technical Parameters
  • Creepage Distance As per IEC 60664-1
  • Volume Resistivity ≥10^12 Ω·cm
  • Dielectric Strength ≥30 kV/mm
  • Operating Temperature -40°C to +180°C
  • Partial Discharge Level <5 pC at 1.5x rated voltage
  • Comparative Tracking Index ≥600 V
Standards
IEC 60243, IEC 60664-1, ASTM D149, ISO 6722
