Bolted tension clamps, type НБ

Bolted tension clamps, type НБ provide the self-supporting fixation of a bare conductor or ground wire to a tension set by means of U-bolts. Body of the tension clamp, type НБ-2-6А, НБ-3-6A is made of aluminum alloy, and of type НБ-2-6, НБ-3-6Б – of malleable iron. Bolted tension clamps, type НБ-3-6А and НБ-3-6Б are fully interchangeable both in terms of the range of wire/conductor diameters and a breaking load. Bolted tension clamps, type НБ meet the requirements of TU U 31.2-30255335-002:2006.
