Preformed dead end is a kind of power fittings made of high-strength materials specially used for overhead lines. It is widely used in ADSS, OPGW, OPPC, AAC, AAAC, ACSR and other transmission lines. The structure of preformed dead end is simple and reliable, and the clamping force can reach the requirements of the national standard. It can withstand the full tension of conductors, ground wires and cables, and ensure the stable operation of the line in various harsh environments. The reliability and economy of preformed dead end are significantly better than the bolt-type and hydraulic tension wire clamps widely used in circuits.
Precautions for installation and maintenance of preformed dead end：
1. Tensioning clamp selection matching: before installing the preformed dead end, the appropriate tensioning clamp model must be selected according to the cross-section, material, working tension of the wire, the type, specifications and operating conditions of the lightning protection wire, so that the tensioning clamp can reliably fix the wire and withstand the specified tension.
2. Pre-installation inspection: before installing the preformed dead end, check the tension clamp to ensure that there are no defects in the tension clamp. In addition, it is necessary to check the insulation properties of the clamp to ensure that it can meet the requirements of the power system after installation.
3. Installation environment requirements: the installation environment of preformed dead end should comply with relevant regulations and avoid environments that may cause damage to the tension clamp. Under bad weather conditions, do not carry out installation operations, so as not to affect the quality and safety of the installation.
4. Regular inspection: conduct regular inspections on the fastening of the installed preformed dead end, the contact with the wire, etc., to ensure that potential safety hazards can be discovered and dealt with in a timely manner.
5. Maintenance and replacement: when the tension clamp is found to have rust, damage or performance degradation during the inspection process, it should be maintained or replaced in time.
6. Safety precautions: when installing and maintaining the tension clamp, relevant safety operating procedures must be observed, such as wearing safety protective equipment and prohibiting single-person operation.
Vilun Electric Co., Ltd's preformed dead end uses recyclable high-performance alloy materials, which are suitable for cables with different protective layers such as galvanized layer and PVC coating to meet environmental protection and diverse needs. This kind of tension clamp can dynamically adapt to the small displacement changes of the cable. When the line is subjected to external forces such as strong winds or earthquakes, it can effectively reduce the damage caused by vibration to the cable and ensure stable operation. At present, preformed dead end has been widely used in many industries and fields such as power, communications, and infrastructure construction.
Vilun Electric Co., Ltd. takes a professional technical team as the core development driving force. Over the years, the company has relied on its own strength to produce more than ten kinds of equipment and components for transmission and distribution lines, and has undertaken power engineering construction projects below 10kV. The products not only enjoy a good reputation in the domestic market, but also are very popular in the international market and are exported to more than 30 countries and regions. Now the company has become a member enterprise of the China Chamber of Commerce for Import and Export of Mechanical and Electrical Products.
