Product Overview

Application

zinc–5 % aluminummischmetal (Zn–5Al–MM) alloy-coated, steel core wire for use in Overhead Electrical Conductors. ACSS ACSS/TW The high temperature low sag solution

Features

operates continuously at high temperatures up to 250°C, with proper steel coating, ensuring maximum utilization and performance; standard coating for high temperature operation is a Zn-5% Al Mischmetal coating so that customers can take full advantage of the 250°C continuous operating temperature rating. Galvanized coatings are rated only 180°C for continuous operation.
