Powering Heavy Loads. Engineered for Maximum Current Capacity. High Current Bushings designed to handle extreme current demands with superior insulation and robust construction.

Overview

Our High Current Bushings are built for high-performance applications in transformers and generators. With a rated current capacity of up to 20,000 kA* and voltage levels up to 36 kV, these bushings ensure safe and efficient power transfer in demanding electrical environments. Designed in compliance with IEC 60137:2017, they deliver reliability, durability, and superior thermal performance.

Key Features

Includes a test tap designed for continuous assessment of insulation performance
Reliable oil sealing is achieved using premium Viton O-rings
Built to tolerate intense seismic activity and withstand high short-circuit forces
Excellent thermal efficiency is ensured through improved heat dissipation
Delivers PD-free operation with an extremely low dissipation/power factor
Capacitive insulation is carefully optimised to maintain a uniform electric field distribution
Aluminium bushing designs feature stainless steel Helicoil inserts at the oil-end for direct transformer lead connections
Strong, solid-rod construction with a precisely machined oil-end termination provides exceptional mechanical durability
