The invention relates to the field of power transmission line galloping prevention, in particular to a damping composite material which is prepared by adopting a double-phase elastomer matrix and compound nano filler system, taking 100 parts of ethylene-propylene-diene rubber as a matrix, and matching 30-50 parts of hydroxyl-terminated polybutadiene, 40-65 parts of silane modified sepiolite, 10-20 parts of hydroxylated graphene, 6-15 parts of di-iso-decylphthalate and the like. Through a synthesis process, the damping composite material is made into the damping element, and the damping element is applied to a damper of the phase-to-phase spacer, so that the problems that damping of a traditional phase-to-phase spacer loses efficacy at low temperature in a cold region, and insulation and damping performance are difficult to consider are solved, and the damping element can still efficiently dissipate galloping energy at extremely low temperature; therefore, the anti-galloping performance and the operation safety of the power transmission line in the cold region are remarkably improved.

The dynamic fatigue and hysteresis performances of fiber reinforced rubber compounds are compared using different plasticizers. Polymer-based fiber reinforced rubber compounds including a non-linear functionalized fatty acid ester, preferably a trimellitate, and more preferably Tris (2-Ethylhexyl) Trimellitate (TOTM) are shown to demonstrate greatly improved dynamic fatigue and hysteretic performance as compared to reference fiber reinforced rubber compounds including conventional reference plasticizers such as Di-isodecyl phthalate (DIDP).
