The parallel groove clamp connects two conductors in parallel for power distribution and transmission systems. It enables non-bearing connections, branching, overhead line jumpers, and tap configurations up to 220 kV in substations, solar, wind, and renewable energy installations.<\/p>\n

A patented universal groove design with blended radii accommodates conductor sizes from #8 AWG to 1750 MCM while minimizing electrical resistance. Interlocking fingers prevent mismatching, serrated grooves increase contact surface area, and an extended lip aligns the clamp during tightening. The base section forms a weather shield protecting the grooves. Constructed from high-strength, high-conductivity aluminum alloy, the clamp resists stress corrosion and galvanic action. Bolts use aluminum with hardened alumilite finish or galvanized steel with inhibitor coatings. Bimetallic variants connect aluminum and copper conductors.<\/p>\n

The clamp accommodates aluminum, copper, Aluminum Conductor Steel Reinforced (ACSR), and Aluminum Alloy Conductor (AAAC) conductors with current ratings from 600 to 2000 amperes. Spring follow-up maintains high contact pressure through thermal cycles. Pre-filled with PENETROX joint compound, the design allows hot application without disassembly, reducing installation time. Specific models feature piercing teeth for insulated cables and dual rating for bare-to-bare or bare-to-insulated connections.<\/p>\n

Installation uses one or two-wrench methods with rotational tightening, eliminating loose parts in field conditions. The clamp holds RUS Accepted status and complies with ISO standards, undergoing rigorous testing for mechanical pull-out, torque, and corrosion resistance.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
