6. Enhanced electrical safety – the grip dead ends prevent accidental disconnections that could lead to power outages. A secure grip reduces the risk of electrical arcing at termination points.
7. Line integrity maintenance – service grip dead ends ensure the continuity and integrity of the transmission line. This is by providing stable termination points for uninterrupted power supply.
8. Cost efficiency – the ease of installation and minimal maintenance needs contribute to cost savings.

The most common types of service grip dead ends.

Service grip dead ends are available in a variety of forms and designs to meet specific application requirements and conductor types. These types contribute to the stability and reliability of the electrical infrastructure. Some of these types are easy to install and have high strength permanent terminations. Also, the choice of grip depends on by elements such as conductor type, load requirements, and climatic conditions. The following are the most frequent types of service grip dead ends used in overhead transmission lines.

• Automatic dead end grips – these use a self-activating clamping mechanism that grips the conductor. They also contain spring-loaded jaws or wedges that grip the conductor. They work in medium and high voltage transmission lines that need quick installation.
• Compression dead end grips – these grips use a sleeve compressed around the conductor using hydraulic tools. This provides a permanent, high strength termination for the conductor.
• Preformed dead end grips – these consist of helical-preformed wires that wrap around the conductor. They have designs to handle high mechanical loads and provide a strong grip on the conductor. Preformed dead end grips are suitable for terminating overhead conductors.
• Guy dead end grips – these have designs to terminate guy wires used for supporting structures like poles. They are suitable for telecommunications and utility structures to secure guy wires.
• Wedge dead end grips – these use a wedge driven into a housing to grip the conductor. It also has designs to handle high tension loads and provide a secure termination.
• Bolt-type dead end clamps – these uses bolts and clamps to secure the conductor to provide a mechanical hold. They are suitable for terminating both overhead and underground cables.
