Strand wires are the backbone of countless infrastructure projects, from power transmission towers to telecom poles and overhead utility lines. Their reliability depends largely on secure termination and protection against tensile stress, environmental damage, and displacement. Among the essential components for strand wire safety, the 5/8” big-grip dead end stands out as a robust solution—combining strength, versatility, and ease of use to safeguard strand wires in critical applications. As a leading global supplier of cable accessories, JERA LINE’s 5/8” big-grip dead end is engineered to meet the highest industry standards, making it a top choice for professionals worldwide.
What Is a 5/8” Big-Grip Dead End?
A 5/8” big-grip dead end (also known as a big-grip dead end clamp) is a specialized fastener designed to terminate and secure 5/8-inch diameter strand wires at their endpoints. Unlike intermediate clamps that focus on alignment, this component bears the full tensile load of the strand wire, preventing slippage, sagging, or breakage—even under extreme conditions like high winds, heavy ice, or long-span installations.
JERA LINE’s 5/8” big-grip dead end features a preformed, self-tightening design that ensures even load distribution across the wire’s surface. Crafted from galvanized steel or corrosion-resistant aluminum alloy, it offers exceptional durability against rust, UV radiation, and harsh weather—critical for outdoor infrastructure that requires long-term performance. The modular structure includes a grip body, tension-adjusting parts, and anti-corrosion accessories, tailored specifically to the mechanical properties of 5/8” strand wires.

Key Applications in Strand Wire Protection
The 5/8” big-grip dead end plays a pivotal role in protecting strand wires across multiple industries, with core use cases including:
-
Power Grid Infrastructure: In medium/high-voltage (MV/HV) power networks, 5/8” strand wires often support OPGW (Optical Ground Wire) cables. JERA LINE’s big-grip dead end secures these strands to transmission towers, bearing their full tensile load to prevent displacement that could cause short circuits or power outages.
-
Telecom and 5G Networks: Telecom poles rely on 5/8” strand wires to support ADSS (All-Dielectric Self-Supporting) cables for data and voice transmission. The dead end’s non-metallic polymer components (for dielectric compatibility) protect the cable’s insulation while ensuring a secure anchor, minimizing downtime in 5G or rural telecom projects.
-
Utility and Construction Projects: From streetlight poles to industrial wiring systems, 5/8” strand wires need reliable termination. The big-grip dead end’s easy installation—requiring minimal tools and no welding—allows field technicians to quickly secure wires, reducing labor time while maintaining protection against environmental wear.
