Insulation barrier Component – Electrical Equipment Manufacturing

Component Specifications

Definition

A specialized insulating component designed to prevent electrical discharge, arcing, and current leakage in high-voltage systems by creating a physical and dielectric barrier between conductive parts. It maintains electrical isolation under extreme voltage stress and environmental conditions.

Working Principle

Works by providing a high dielectric strength material path that interrupts conductive pathways, preventing electron flow between high-voltage components. It withstands electrical stress through material properties that resist ionization and tracking.

Materials

High-purity alumina ceramic (Al2O3 ≥ 95%), silicone rubber composite, or glass-reinforced epoxy. May include hydrophobic coatings for outdoor use.

Technical Parameters

Flame Rating UL94 V-0
Creepage Distance ≥ 25 mm/kV
Dielectric Strength ≥ 20 kV/mm
Surface Resistivity ≥ 10^12 Ω
Tracking Resistance CTI ≥ 600
Operating Temperature -40°C to +150°C

Standards

ISO 1463, DIN 40685, IEC 60672
