An OPGW (Optical Ground Wire) tension clamp is a specialized device used in the installation and maintenance of OPGW cables. OPGW cables are composite overhead cables that combine optical fibers for communication purposes with a metallic ground wire for power transmission and grounding.
The OPGW tension clamp serves the purpose of securely attaching the OPGW cable to the supporting structure, such as poles or towers, while maintaining the necessary tension. It plays a crucial role in ensuring the stability and reliable performance of the OPGW system.
Here are some functions of an OPGW tension clamp:
Cable Gripping: The tension clamp is designed to securely grip the OPGW cable to prevent it from slipping or becoming loose. It typically consists of specially designed jaws or grips that firmly hold the cable in place.
Tension Adjustment: The clamp allows for adjustment of the tension applied to the OPGW cable. This feature is important to maintain the desired tension level in the cable, which is essential for its proper functioning and mechanical stability.
Mechanical Strength: OPGW tension clamps are constructed using robust and durable materials, such as stainless steel or aluminum alloy, to provide high mechanical strength. This ensures that the clamp can withstand the tension forces exerted on the cable and withstand environmental conditions, such as wind and ice loading.
Electrical Continuity: The tension clamp also maintains the electrical continuity of the metallic ground wire within the OPGW cable. It provides a reliable connection between the cable and the supporting structure, ensuring effective grounding and electrical performance.
Corrosion Resistance: OPGW tension clamps are often designed with corrosion-resistant coatings or materials to withstand exposure to harsh outdoor environments, including moisture, UV radiation, and temperature variations.
Preformed tension clamp is also called preformed dead end or dead end cable clamp. The raw material of preformed tension clamp is aluminum clad steel wire or galvanized steel wire, For communication ADSS optical fiber, OPGW cable and OPPC. The unique pre-formed tension clamp design not only simplifies the installation but also ensures the safety of the cable connection. Terminal cable clamps provide excellent performance to protect ADSS/OPGW/OPPC cables from stress points and prevent signal drops during transmission. What is the raw material of the pre-formed tension clamp The raw material of the prefabricated tension clamp is aluminum-clad steel wire or galvanized steel wire. What is the purpose of prefabricated tension clamps Prefabricated tension clamps are designed to connect ADSS/OPGW/OPPC to overhead towers or poles. What are the types of prefabricated tension clamps The preformed tension clamp and guy wire dead end grips used on the conductor and earth wire look alike in shape, but there are really big differences in the specification, raw material, and strength requirement of the two types of guy grips. 1. Dead-end for short span ADSS Dead-end for short span ADSS with a small tension clamp material for aluminum-clad gang wire, mainly used for the corner towers, the middle of follow-tower and connecting the terminal tower, the largest installation file from the less than 100 meters. 2. Dead-end for medium/long span ADSS Dead-end for medium span ADSS in tension and large tension clamp material for aluminum-clad steel wire, mainly used for files larger than 100 meters away from the corner tower, the middle tower and Terminal Tower successive connection.
