Product Introduction

Resin Impregnated Paper (RIP) bushings use crepe paper and aluminum foil electrodes as main insulation, forming a capacitor core cured after impregnation with epoxy resin. The external insulation adopts porcelain or composite insulator, achieving pollution class III and IV. The design is completely dry — no insulating oil or SF6 gas above the mounting flange.

Technical Strengths

Advanced Electric Field Design

International professional electric field analysis software and high-voltage bushing internal insulation optimization design package for optimal internal and external insulation, core calculation and field strength optimization.

Precision Winding Process

Imported whole paper winder with seamless paper and aluminum foil lapping technology. Laser-accurate electrode positioning and winding tension control ensure uniform axial and radial field strength.

Vacuum Drying & Casting

Imported mixing and pouring system with vacuum drying ensures complete resin degassing and full core drying. Results in smaller dielectric dissipation and lower partial discharge for superior electrical performance.
