Component Specifications

Definition
A specialized insulating frame or support component designed for transition resistors/reactors in electrical systems. It provides mechanical support to maintain proper positioning of electrical elements while ensuring high-voltage electrical isolation between conductive parts and grounded structures. This component prevents electrical arcing, reduces leakage currents, and maintains safe operational distances in high-voltage environments.
Working Principle
The insulating frame/support operates on the principle of dielectric isolation, using materials with high dielectric strength to prevent electrical current flow between conductive components. It maintains physical separation between energized parts and grounded structures while providing structural rigidity to withstand mechanical stresses from thermal expansion, vibration, and electromagnetic forces during operation.
Materials
High-performance thermoset composites (glass fiber reinforced epoxy or polyester), ceramic-filled polymers, or high-grade industrial ceramics. Materials must have dielectric strength >15 kV/mm, volume resistivity >10^12 Ω·cm, and thermal stability up to 180°C continuous operation.
Technical Parameters
  • Flame Rating UL94 V-0
  • Creepage Distance ≥25 mm/kV
