The main role of ADSS dead end tension clamp is to provide long-lasting and reliable tension anchoring for ADSS optical cables. During the erection of the optical cable, each section of the optical cable needs to withstand the telescopic stress caused by its own weight, wind, ice and snow loads, and temperature changes. Through precise structural design, the ADSS dead end tension clamp can evenly transmit these dynamic tension to the support structure such as the tower, while avoiding the sheath damage or core fracture caused by the concentration of local forces on the optical cable. Unlike ordinary wire clamps that only need to meet connection requirements, ADSS dead end tension clamp also needs to solve two other pain points: electrical corrosion protection and dynamic stress cushioning between optical cables and wire clamps. Since ADSS optical cables are often erected in the same tower as high-voltage lines, the wire clamps need to have excellent insulation properties to prevent electrochemical corrosion caused by inductive electric fields. And in the case of strong winds or sudden temperature changes, the clamp needs to absorb the axial displacement of the optical cable through the elastic components to avoid long-term fatigue damage.
For buyers, choosing the wrong ADSS dead end tension clamp may cause knock-on engineering risks. A 2022 case of a European power grid company showed that they used universal tension-resistant wire clamps in the transformation of rural power grids. They only used them for 6 months because of insufficient adaptability of the wire clamps and optical cables, which caused three optical cables to slip off, which not only caused nearly one million euros in emergency repair costs, but also caused regional communication interruptions. Other projects that use professional ADSS dead end tension clamp, such as a cross-river optical cable project in Southeast Asia, even if they withstand high humidity and strong typhoons all year round, the clamp still maintains zero-failure operation, and the attenuation rate of optical cable transmission has been well controlled, which is much lower than the industry average. This comparison clearly shows that the tension-resistant clamp is not a standard part, but a customized component that needs to be accurately matched with the structure, outer diameter, and force characteristics of the ADSS optical cable. The quality of the clamp will also directly determine the safety and economy of the project.
As a manufacturer that has been deeply engaged in the field of power fittings for many years, our ADSS dead end tension clamp has always been oriented to solving the actual pain points of buyers in the design and production, and has built three differentiated advantages. They are full-scene adaptability, maintenance-free design and full-process quality control system. In terms of full-scene adaptation, our ADSS dead end tension clamp will optimize the material formula for different climatic regions. In terms of maintenance-free design, our ADSS dead end tension clamp integrates a self-lubricating bushing, which can reduce the friction loss of optical cables and wire clamps. At the same time, it is well sealed, which can effectively avoid the aging of components caused by rain, sand and dust intrusion, and the maintenance cycle is significantly extended, which can significantly reduce the late operation and maintenance costs of buyers. In addition, in the whole process quality control system, we will implement multiple testing processes from the procurement of raw materials to the delivery of finished products to ensure product quality. At the same time, we are equipped with a professional technical team, which can provide full-cycle services from selection consultation to installation guidance, to help buyers quickly solve technical problems in construction and make the project delivered on schedule.
