Parallel groove cable connector with bolts the parallelgroove clamp is used for the connection of the small cross-section of thealuminum strand or acsr, but also for non-linear tower jumper connection. The splicingfitting is primarily used to join kinds of bare conductors and lightningconductors. It bears the same electric load as conductors. Most splicingfittings bear all the tension of conductors, ground wires and lightningconductors. According to thetensile condition, splicing fittings include force-bearing type andnon-force-bearing type. Splicing fittingsare generally divided into compression type and preformed type.and thecompression type includes hydraulic compression, explosive compression andcompression with pliers. Generally, malleablecast iron, steel, and aluminum alloy are used a it's materials. All the ferrousmetal should be hot-dip galvanized. catalog no.
