Ceramic Post Insulator, Porcelain Ground Bar Standoff Insulator,1.6”x1.6” High-Voltage Insulation for Power Line, Copper Busbar ,Electrical Fencing Insulation Support

✅ Superior High‑Voltage Insulation Performance Made of premium glazed 95‑alumina ceramic. Long‑term continuous working voltage reaches 5‑6kV AC under wet & rainy outdoor conditions; short‑time dry‑condition withstand voltage up to 12‑14kV AC. Multi‑shed corrugated umbrella structure greatly extends creepage distance, effectively avoids electric leakage and surface flash‑over for damp, dusty or oil‑contaminated working scenarios. ✅ Precision Embedded Brass Threaded Insert Comes with pre‑pressed M8 brass threaded insert for stable fastening. Provides tight, jam‑free thread connection when mounting to brackets and conductive parts. Features solid mechanical locking strength for quick and straightforward assembly. Note: Only single‑end internal thread, external bolts included. ✅ Excellent Mechanical & Weather Resistance High‑temperature fired ceramic body resists impact, vibration, thermal shock, UV and weather aging. Stable performance under drastic temperature changes, sun exposure and rain. Suitable for long‑term indoor and outdoor service with long service lifespan. ✅ Wide Compatibility & Easy Installation Direct mounting onto equipment frames, mounting brackets and busbars without extra modification. Perfect for ESP fume smoke purifiers, industrial high‑voltage equipment, electrical fencing, distribution accessories and other electrical projects. Fits most general high‑voltage isolation applications. ✅ Strict Quality for Industrial‑Grade Use Glazed ceramic surface repels dust and grime, easy to clean. Manufactured under industrial standards for high‑voltage isolation requirements. Ideal replacement part for maintenance and new equipment assembly.
