Low-dielectric-loss high-weather-resistance filling rope
ActiveCN222631939UExtended service lifeavoid stickingClimate change adaptationTextile cablesWeather resistanceDielectric loss
The utility model discloses a low dielectric loss high weatherproof filling rope, including rope core, weatherproof layer and buffer layer, the periphery of rope core is covered with the buffer layer, and the weatherproof layer is filled between the buffer layer and rope core, the buffer layer is internally provided with a plurality of insertion slots in a surrounding manner; according to the utility model, the periphery of the stranded rope core is coated with the buffer layer which is made of polypropylene and has the thickness of 0.05-0.08 mm, so that buffer elasticity is provided for the filling rope, and the phenomenon that the filling rope is adhered to the moisture-proof layer due to the broken buffer layer is prevented; the functional belts made of low-dielectric-constant resin materials are embedded and installed in the multiple insertion grooves of the buffer layer, so that the filling rope meets the requirement for low dielectric loss, the weather-proof layer made of polyurethane materials is filled between the rope core and the buffer layer, it is guaranteed that the rope core is tightly connected with the buffer layer, meanwhile, all-around protection is provided for the rope core, and the service life of the rope core is prolonged. Interference of the external environment is effectively isolated, weather resistance is excellent, and the service life of the filling rope is prolonged.
