What Is a Dead End Grip? Complete Guide for ADSS and OPGW Cable Installation

The Dead End Grip (also commonly referred to as a dead end clamp or cable dead end) is an indispensable, critical fastener used in the deployment of overhead ADSS (All-Dielectric Self-Supporting) and OPGW (Optical Ground Wire) cables. It serves as the crucial anchor point for the cable on poles or towers, essential for ensuring the long-term reliability of the network.

I. Core Function and Design Principles of the Dead End Grip

1. Key Role: Bearing Full Tensile Load

Unlike intermediate clamps, which are only used for path alignment, the sole mission of the Dead End Grip is to withstand the entirety of the mechanical tensile load at the cable's termination point.

• Preventing Displacement: Ensures the cable does not slip or shift at the anchor location.
• Eliminating Sagging: Maintains the preset tension of the cable across the span, preventing excessive sagging.
• Resisting Environmental Stress: Especially under severe weather conditions (such as high winds and heavy ice), the Dead End Grip must remain stable to prevent cable damage or breakage.

2. Basic Structure and Installation Characteristics

The Dead End Grip features a modular design, typically consisting of the following core components: the Grip Body, tension-adjusting parts, and anti-corrosion accessories.

• Ease of Installation: Utilizing a preformed helical structure, on-site installation is fast and simple, requiring no welding and minimal specialized tools, significantly reducing labor time.
• Customized Matching: Its design and manufacturing must be precisely tailored to the specific mechanical characteristics (e.g., tensile strength, diameter, material type) of the ADSS/OPGW cable it secures.

As a leading global supplier, China's Jera Line offers a full range of Dead End Grips, providing competitive pricing and globally recognized quality compliant with IEC/ANSI standards, serving Medium/High-Voltage (MV/HV) power and telecom networks.

II. Key Technical Features and Material Compatibility

The efficient operation of the Dead End Grip relies on its superior load-bearing capacity and targeted material design.

1. Ultra-High Tensile Load-Bearing Capacity

The Dead End Grip possesses an extremely high tensile load capacity, capable of fully securing the entire pulling force of the ADSS/OPGW cable.

• Typical Load Range: Depending on the model and design, its maximum bearing capacity typically ranges between 50 kN and 120 kN, effectively preventing the cable from slipping or breaking at the termination point.
• Environmental Durability: Its high load capacity remains stable even under extreme climatic conditions like high wind speeds and heavy icing.

2. Cable-Specific Material Compatibility Design

To ensure a perfect match with different cable types and guarantee network safety, the clamp's materials are specially customized:

3. On-Site Installation Advantages

The modular, weld-free design allows field technicians to quickly adjust tension and secure cables, thus lowering labor costs and simplifying installation complexity.

III. Primary Applications of Dead End Grips

The Dead End Grip is a critical component for ensuring the stability of modern power and communication infrastructure, with broad and important applications:

1. OPGW Application in Power Transmission Grids (MV/HV)

• Secure Anchoring: Fixes OPGW (Optical Ground Wire) cables to the termination points on utility poles or transmission towers of Medium/High-Voltage power lines.
• Preventing Faults: Bears the full mechanical tension, preventing OPGW cables from shifting within the power network, thus effectively avoiding potential short circuits or outages.

2. ADSS Application in Telecommunication Networks (5G/Rural Coverage)

• Data Assurance: Used for terminal securing of ADSS cables in telecom networks, such as 5G deployment and rural communications.
• Ensuring Transmission: Protects ADSS cables from damage, ensuring the uninterrupted transmission of data and voice.
• Span Anchoring: Provides a secure and reliable anchor for the connection and termination of different cable spans, which is vital for the long-term performance of the telecom infrastructure.
