Product Specifications

Technical details and manufacturing context for Electric Power Fitting

Definition

Electric power fittings are essential components in overhead power transmission and distribution systems, used to connect conductors to insulators, support conductors on towers, and protect them from mechanical and electrical stresses. They are specified based on conductor size, voltage level, mechanical load, and environmental conditions. Grades are distinguished by material quality, manufacturing precision, and compliance with international standards, affecting durability and reliability.

Working Principle

These fittings work by providing secure mechanical connections and electrical continuity. They distribute mechanical loads from conductors to supporting structures, while maintaining electrical conductivity and preventing corona discharge. Their design ensures reliable performance under tension, vibration, and thermal expansion.

Common Materials

Aluminum alloy (e.g., 6061-T6), Galvanized steel (e.g., ASTM A153), Stainless steel (e.g., 304), Copper alloy (e.g., C11000), Cast iron (e.g., ASTM A47)
