Advantage of High performance fiber composite drop lump: adjustable density, adjustable thickness, no absorbing water, no tust, resistance to acid and alkali erosion, not easily stolen, and has the characteristics of high strength and impact resistant, Can be directly used in damp, acid, alkaline and sandstorm environment. It can greatly prolong the service life of the drop lump, and will improve the stability of power grid operation.
