Transmission line icing in the wind can be generated under the excitation of conductor galloping phenomenon,caused by interphase short circuit tripping wire disconnection,burns,fittings, insulation damage of tower are and inverted tower strict heavy accident. China’s galloping of conductor of multiple regions, in recent years,the frequent conductor galloping gives our country brought inestimable economic losses and social influence.Composite interphase spacer is a can effectively prevent the line galloping through the control device ,the wire distance and inbibition of conductor galloping to keep the line safety, and effectively reduce the transmission corridor space ,network in the country dance dynamic control guidance is classifed as a compact high voltage transmission line and 220KV and below voltage transmission line galloping prevention measures are preferred. My company from 2004 began spacers in the anti-galloping research,development of different voltage levels,different types of towers and lead arrangement mode,the different requirements of the user products,for many years running since good response on the line,effectively avoid the occurrence of dancing , get the user’s praise.Span 180 meters, can be installed in a group of 180 to 300 meters, can be arranged in two groups, can also be based on the operation experience and the observed wave intensity automatically determine, mounting a group may choose in the span of 1/2 to side 1~5m, installed two groups may choose in the span of 1/3 and 2/3 to say, lateral 1~5m, The actual installation according to wires K value and operation experience to determine. 1.A three-phase linkage type strure, the dance between effective mutual inhibition 2.The insulator and the line spacing rod intermediate, keep the line without torsion 3.Insulator for double adjustable design, the solution of the original circuit installation vertical deviation 4.Using aluminum alloy and manufacture of energy-saving special clamp, the mechanical strength of grade 1t, the grip is not less than 5% of the tensile load calculation of conducting wire 5.Contact wire wear resistant damping rubber parts using 6.Connecting parts made of wear resistant design1.Insulator in the transportation and installation to should take put down gently, and should not be thrown, and to avoid all kinds of miscellaneous pieces of (wire, iron plate, tools, etc.) and sharp hard object collision and friction. 2. When the composite insulator is hoisted, the knot is tied on the end accessories, and it is strictly forbidden to hit the shed or sheath. The rope must touch the shed and the sheath, and the contact part should be wrapped with soft cloth. 3. Do not use the composite insulator as an auxiliary tool for placing (retracting) wires, so as not to damage the insulator due to impact force or bending moment. 4. It is strictly forbidden to step on the insulator umbrella skirt
