What materials can an extra-high-strength (EHS) cable be made of?

Extra-high-strength (EHS) cable is specifically designed for applications that require enhanced tensile strength and durability. The most common material for manufacturing EHS cable is 7-strand steel. This material provides the necessary strength and flexibility for supporting trees or other structures, particularly in environments where high winds and severe weather conditions are prevalent.

The design of 7-strand steel cables involves multiple strands twisted together, which not only improves the overall strength of the cable but also allows for a degree of flexibility that reduces the risk of breakage under tension. The high tensile properties of steel make it particularly well-suited for applications in tree support systems and lightning protection, as it can withstand significant loads without deforming or losing integrity.

Other materials listed, such as plastic, fiber, aluminum, brass, rubber, and nylon, do not possess the same high tensile strength as 7-strand steel and are generally not utilized in the production of EHS cables. Instead, those materials may be more suitable for other applications, but not for the demanding requirements of EHS installations where maximum strength is essential.
