Product Description

Product Overview

ED series porcelain stay insulators (disc type / spool type) are specially designed for guy wire and stay wire tension insulation on 1kV to 10kV low-voltage overhead distribution lines. Made of high-alumina electrical porcelain (Al2O3 >=25%) with blue and white glaze finish, they feature high transverse strength (9.1kN to 13.6kN), stable insulation performance, and strong resistance to aging and weathering. The compact disc structure ensures easy installation with stay wire hardware and tension fittings. Widely used for pole guy wire insulation in urban distribution networks, rural grid renovation and low-voltage power projects.
