Product Name: F4y Preformed Vibration Damper for Transmssion Line Model NO.: F4Y Preformed Vibration Damper: for Transmission Line Trademark: tienchan Transport Package: Wooden Case Specification: CE Origin: China HS Code: 8537109090 Product Description F4Y Series Preformed Vibration DamperI. The comparision of preformed damper and traditional bolt fixed vibration damperTraditional bolted damper, installation construction personnel must be equipped with a torquewrench, if the construction team did not have these tools, torque occurs too large or too smallfor the situation. Too much torque causes damage to wire or bolt; too small torque, the gripstrength between the vibration damper and conductors can not be reached. Even with a torquewrench construction, vibration hammer and wire grip between the installation meetrequirements, but with the line running in the wire and vibration damper, wires and bolts ofstress relaxation, the grip between the wire and anti-vibration damper decreases, will cause vibration damer loose clamp, resulting in deviationfrom the initial installation of damper position, this phenomenon has been put into operation in the line occur.Preformed damper eliminates the above shortcomings of bolt fixed dampers. Installed preformed damper do not need hand tools to complete the task, easy installation, quick, low cost construction, damper installation guide preformed wire between the grip and dispersed in the region of 30 to 60mm length, and avoid the wire stress concentration. Excellent performance of aluminum clad steel wire material to ensure the steady and reliable grip between preformed wire and the conductors. Experimental results show that 200 million times through the vibration. The vibration damper without any displacement relative to the wire, and wire surface without any damage, anti-vibration damper itself is intact.In addition, the installation quality of preformed damper can be installed on the groundwith a telescope to observe and judge, which greatly reduces the difficulty and cost ofproject acceptance, greatly improve the reliability of acceptance. In summary, preformeddampers' advantages can be summarized as following:Easy installation, low installation costs;Safe, reliable, maintenance-free;The construction of efficient, convenient and reliable inspectionII. Composition of preformed fixed damper:Aluminum clad steel wire installation of preformed damper;Vibration hammer (fork hammer, hanging wire and aluminum have been combined into one)III. Mounted damper installation steps of preformed damper:Preformed wire will be installed across the whole clip (ie, clamp installation in the following figure), the clamp in the middle of preformed wire;So that the installation of the wire clamp aligned position, the left and right ends ofthe preformed wire even natural can be wrapped around the wire.Application / installation instructions:Damper installed in the aluminum stranded wire, aluminum alloy stranded wire, steel core aluminum stranded wire and steel core aluminum alloy stranded wire, is located the wire near the insulator sting and the ground wire of suspension and tension.Consumed by the resonance vibration damper wire into the wind, so as to achieve to reduce wire vibration, the purpose of protecting the wire.Damper must match with the wire, otherwise, dampers can cause wire damage, or their damages. In order to achieve optimal results vibration damper, you must do the following-- select the appropriate damper type;-- the correct location to install the vibration damper-- install necessary numbers of vibration damper-- with a particular computer program, to provide the best design of the vibration--provide suitable damper type number
