Tension and suspension fittings provide secure connections for overhead transmission lines in power distribution systems. These hardware components complete assembly tasks across voltage levels including 132kV, 230kV, and 400kV applications, with variants such as single tension, double tension, suspension fittings, disc hardware fittings, and compression dead-end clamps. They deliver robust performance in substations, transmission networks, and electrification projects where reliable conductor connections are critical.
The fittings utilize high-grade aluminum alloys or galvanized steel selected for corrosion resistance and light weight. Seamless extruded aluminum alloy tubes and hot dip galvanized components resist moisture and chemical exposure. High tensile strength and breaking strength enable the fittings to withstand dynamic stress and high impact loads without stress concentration, while precise dimensional accuracy ensures consistent grip strength and mechanical reliability.
Manufacturing incorporates quality-tested graded alloys processed under International Organization for Standardization (ISO) 9001 certification. Production includes design, testing, and validation from raw materials through finished products, with stringent checks on strength, rigidity, and dimensional accuracy. The hot dip galvanized finish enhances longevity and environmental protection, supporting extended service life with minimal maintenance requirements across electrical, petrochemical, and construction applications.
