OPGW Optical Cable Tension Clamps/Dead-end Fittings Abstract: The OPGW (Optical Ground Wire) optical cable tension clamps and dead-end fittings play a crucial role in the installation and maintenance of optical cables. These components ensure the proper tensioning, support, and termination of the cables, ensuring reliable communication networks. In this article, we will delve into the details of OPGW optical cable tension clamps/dead-end fittings from four aspects: their purpose, types, installation process, and benefits. 1. Purpose Tension Clamps: Tension clamps are used to provide mechanical support to OPGW cables by securing them to poles or towers. They prevent excessive sagging or movement of the cables due to environmental factors such as wind or ice load. Tension clamps distribute the tensile forces evenly along the length of the cable while maintaining its integrity. Dead-End Fittings: Dead-end fittings are designed for terminating an OPGW cable at its ends securely. They prevent any slippage or disconnection between different sections of a cable line while also providing protection against external elements like moisture and dust. 2. Types Tension Clamps: There are various types of tension clamps available for different applications in OPGW installations: a) Suspension Clamp: This type is used for supporting straight sections between poles or towers. b) Anchor Clamp: It is utilized at anchor points where significant tensions need to be handled. c) Mid-span Clamp: Mid-span clamp allows additional support in long spans where extra sag control is required. Dead-End Fittings: Similarly, there are multiple options when it comes to dead-end fittings: a) Preformed Dead-Ends: These consist of preformed rods that grip onto the outer strands of an OPGW cable using compression technology. b) Helical Dead-Ends: Helical dead-ends use helically-formed wire grips that hold onto both inner fibers and outer strands through a combination gripping mechanism. c) Wedge Grip Dead-Ends: This type employs wedge-shaped grips that secure both inner fibers and outer strands with high strength retention capabilities. 3. Installation Process Installing tension clamps/dead-end fittings requires careful attention to detail: a) Tension Clamp Installation: i) Identify suitable attachment points on poles/towers based on design specifications. ii) Position clamp around an appropriate section of an OPGW cable without damaging it. iii) Securely fasten bolts/nuts provided with each clamp model according to manufacturer guidelines. b
