Tension spiral clamps of type NS are designed for anchoring SIP-3 conductors. They are supplied with piercing clamps and a shunt for connecting the conductor to the thimble. The spiral clamps are made from high-strength aluminum alloy wire, and the thimbles are made from aluminum alloy, ensuring connection to standard coupling fittings and insulators. Installation of the clamps does not require removing the insulation from the conductor and does not cause losses due to remagnetization. The products are manufactured according to technical specifications TU 3449-001-52819896-2017.
