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.

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.
OEM ADSS Tension Clamp Pre-twisted tension clamps are also known as pre-twisted dead-end or dead-end cable clamps for communication ADSS fiber, OPGW cable or OPPC. Pre-twisted dead end is a tension clamp that plays an important role in ADSS/OPGW transmission lines. Dead-end fiber optic cable clamps are used to connect ADSS/OPGW/OPPC to overhead towers or poles. The unique design of the pre-fabricated tension clamps not only simplifies installation, but also ensures a secure cable connection. Dead-end cable clamps provide superior performance in protecting ADSS/OPGW/OPPC cables from stress point damage and preventing signal degradation during transmission. Pre-twisted tension clamps and pulling dead-end cable clamps used on conductors and ground wires are similar in appearance, but the specifications, raw materials, and strength requirements of the two types of pulling dead-end cable clamps are quite different. Although there are different design standards in different countries, we can make OEM according to customers' requirements.
Custom ADSS Tension Clamp ADSS Tension Clamps are used to connect ADSS cables to poles/towers. Armored rods provide protection and cushioning for the ADSS cables. The special design of the prefabricated rods ensures that the tension clamps do not overstress the ADSS cables, thus ensuring a normal service life of the cable system.The ADSS tension clamps are made of aluminium-clad or galvanized steel wire. Structure and raw materials Unshackle - hot-dip galvanized steel. The shackle is connected to the reinforcing bar unit. Twisted chain ring - hot dipped galvanized steel. Twisted links are used to connect the shackle to the thimble. Sleeve - hot dip galvanized cast steel. The sleeve is inserted into the unclamp of the tension clamp to provide protection and connection. Armored rod ----- Aluminum clad steel wire. Armored rods increase friction through a layer of granular emery inside the cable. The rods are shop assembled into four subsets to minimize misalignment errors and speed installation. The ends are bent outward to provide strain relief in critical cable departure areas. Prefabricated Dead Ends - Prefabricated dead ends are made from hot-dip galvanized steel wire or aluminum-clad steel wire and are assembled in the shop into a subset with a solid layer of emery to increase the grip of the tensioning clamps while reducing lateral pressure. Direction 1. Used for connecting connecting poles (towers) to terminal poles (towers), tension poles, or poles (towers) with line clamping angles of 25�° or more. Special specifications: 1 unit for each terminal pole (tower), 2 units for each tension pole (tower), and 2 units for each connecting pole (tower). You can select the specification model corresponding to the appropriate cable diameter range, maximum allowable tension (MAT) or span length from the data sheet.
