The TG series wall bushings are engineered to provide a fully insulated passage for conductors through the metal enclosures of medium-voltage switchgear and substations. Manufactured from high-strength epoxy resin, they combine superior dielectric resistance and mechanical robustness to ensure safe, reliable operation even under harsh environmental and thermal conditions.
With precision-engineered mounting interfaces and low partial-discharge characteristics, these bushings simplify installation and extend service life. Their maintenance-free design and standardized dimensions make the TG series an ideal solution for modern power distribution networks seeking durability, safety, and ease of integration.
