Description
The lower bushing conductor is a machined component made from high-conductivity electrolytic copper (ETP), designed for application in the lower bushings of power transformers. It connects the internal windings to the bushing terminal, ensuring the safe and efficient conduction of high electrical currents with minimal Joule losses.
Manufactured in various lengths, outer diameters, and interface configurations, it can be tailored to meet project-specific requirements for current ratings typically ranging from 1,000 A to 3,150 A. The conductor includes precision-drilled mounting holes, machined surfaces for electrical connections, and optional surface treatments for enhanced performance and durability.
Key technical features:
-
Material: Electrolytic copper (ASTM B187 / ETP, ≥99.9% purity)
-
Rated current: from 1,000 A to 3,150 A
-
Available geometries: multiple options for length, diameter, and mounting interfaces
-
Fixation: includes two precision-aligned through-holes for mechanical fastening
-
Surface finish options: bare copper, tin-plated, or silver-plated
-
Compatibility: oil-filled, capacitive, or dry bushings
Engineered to ensure low electrical resistance, thermal stability under continuous or fault conditions, and dimensional accuracy, the lower bushing conductor is ideal for high-reliability applications in medium- and high-voltage equipment.
