Dead End Grip vs Wedge Clamp: Which Is Better for ADSS Cable Installation

• Understanding Dead end grip

A dead end grip (also known as a dead end clamp or cable dead end) is a specialized fastener designed to secure the termination point of ADSS cables to utility poles or transmission towers. It bears the full tensile load of the cable, preventing slippage, sagging, or damage even in harsh weather conditions like high winds and heavy ice. Tailored to ADSS cables’ mechanical properties (such as tensile strength and diameter), it typically features a preformed, self-tightening design with components like a grip body, tension-adjusting parts, and anti-corrosion accessories.

• Understanding wedge clamp

A wedge clamp is a simpler fastening device that uses a wedge-shaped component to compress and hold the cable in place. It relies on friction between the wedge and the cable surface to resist movement, making it a cost-effective choice for low to medium tensile load applications. However, its design limits load distribution and long-term stability, especially in demanding environments.

Key Comparison: Dead End Grip vs Wedge Clamp for ADSS Cable

1. Tensile Load-Bearing Capacity

Dead end grip: Excels in high-load scenarios, with a typical maximum tensile load of 50–120 kN (model-dependent). It evenly distributes the cable’s tensile force, avoiding localized stress that could damage the dielectric layer of ADSS cables.

Wedge clamp: Suitable for light to medium loads only. Uneven pressure from the wedge may cause cable deformation over time, increasing the risk of slippage or breakage in high-voltage (HV) or long-span installations.

2. Cable Protection and Durability

Dead end grip: Made from cable-specific materials (e.g., non-metallic polymer cores for ADSS), it avoids conductivity and protects the cable’s insulation layer. Galvanized steel or aluminum alloy construction, paired with anti-corrosion and UV-resistant coatings, ensures long-term performance in harsh environments (coastal, industrial, rural).

Wedge clamp: The wedge’s compressive force can wear down the cable’s outer layer over time, especially under dynamic loads (e.g., wind-induced vibration). It also has weaker corrosion resistance, making it less reliable for long-term outdoor use.

3. Installation and Flexibility

Dead end grip: Features a modular, tool-friendly design that requires no welding. Field technicians can quickly adjust tension and secure cables, reducing labor time. It also offers wide size compatibility to fit different ADSS cable diameters.

Wedge clamp: Installation is straightforward but requires precise alignment to ensure proper clamping. It has limited size flexibility and may require frequent re-tightening to maintain grip, increasing maintenance costs.

4. Application Suitability

Dead end grip: Ideal for critical applications like MV/HV power grids, 5G telecom networks, and long-span cable installations. It provides stable termination and uninterrupted data/voice transmission, even in extreme weather.

Wedge clamp: Best for low-voltage, short-span projects or temporary installations where cost is the primary concern. It is not recommended for high-stress or harsh-environment applications.

Why Dead End Grip from JERA LINE Factory Stands Out

1. Secures termination points of overhead ADSS (telecom/data) and OPGW (power/grounding) cables to utility poles or transmission towers, anchoring cable spans.
2. Bears full tensile load in medium/high-voltage (MV/HV) power grids to prevent OPGW cable displacement, avoiding short circuits or outages.
3. Protects ADSS cables in telecom networks (e.g., 5G, rural telecom) from damage, ensuring uninterrupted data/voice transmission.

Why Choose Jera Line as your Dead End Grip supplier?

When choosing a dead end grip for your ADSS cable project, partnering with a reliable supplier is just as important as the product itself.

• Conclusion: Which Should You Choose?

For ADSS cable installations that demand reliability, durability, and long-term performance—especially in high-load, harsh-environment, or critical infrastructure projects—dead end grips are the superior choice. Wedge clamps may suffice for low-budget, temporary, or light-load applications, but they cannot match the dead end grip’s tensile capacity, cable protection, and stability.

When it comes to sourcing dead end grips, JERA LINE factory stands out as a trustworthy partner. Its standards-compliant, customizable, and cost-effective solutions, paired with expert technical support, make it the go-to supplier for ADSS cable projects globally. Whether you’re working on a 5G telecom network, an MV/HV power grid, or a rural telecom infrastructure project, JERA LINE’s dead end grips ensure safe, stable, and uninterrupted cable performance.
