FE140 Stay Wire for Guard and Earth

FE140 Stay Wire for Guard and Earth Construction

• Galvanized steel wire 
• Concentric, multi-wire strand

FE140 Stay Wire for Guard and Earth Application

• Tension wires: Provide necessary lateral support for utility poles, transmission towers, and overhead lines, and balance mechanical loads.
• Lightning arresters: Installed above or alongside power conductors to intercept lightning strikes and protect the live power grid.
• Grounding wires/static dissipation wires: Ground the overhead transmission line structure and safely divert fault currents into the ground to prevent equipment damage and ensure public safety.

FE140 Stay Wire for Guard and Earth Standard

• SS 424 08 06

FE140 Stay Wire for Guard and Earth Feature

• High Strength Grade: The “140” in FE140 Stay Wire typically refers to the tensile strength grade (e.g., approximately 1400 MPa or a specific breaking load). It is a cold-drawn steel wire with mechanical properties far superior to those of ordinary low-carbon steel wire, enabling it to withstand significant lateral tensile forces.
• Dual-Function Design: Serves as a “Guard” (protective/tension wire) to secure utility poles or towers and balance line tension; simultaneously utilizes its metallic conductivity as part of the “Earth” (grounding) system to conduct fault currents. When in use, it is typically paired with tension wire insulators to electrically isolate the upper and lower sections, maintaining mechanical connection while preventing stray currents to the ground.
• Standard Cross-Sections and Corrosion Protection: Common specifications are around 25 mm². The surface is generally hot-dip galvanized, providing a certain level of corrosion resistance and making it suitable for outdoor environments.
