Subcategories & Engineering Architectures
OIP Bushings
Oil-Impregnated Paper core with hermetically sealed porcelain or composite insulator; legacy workhorse for bulk EHV applications.
RIP Bushings
Resin-Impregnated Paper dry-type core with silicone composite housing; explosion-proof, moisture-resistant, zero fire hazard.
RIS Bushings
Resin-Impregnated Synthetic mesh with zero cellulose moisture absorption; highest thermal endurance and lifetime reliability.
LV / Generator Bushings
High-current copper stem designs with forced-oil/air/water cooling options for GSU delta connections up to 50 kA.
Direct GIS Connections
SF6-to-oil terminations eliminating exposed overhead clearances in compact substations.
