FIELD: electric power engineering.
SUBSTANCE: invention relates to the field of electric power engineering and can be used as tension clamps of aluminium and steel-aluminium non-insulated wires intended for transmission of electric power via overhead power transmission line. Design of the tension clamp consists of a casing made of nonmagnetic material, including aluminium or aluminium-based alloy, tightening bolts located in cylindrical holes of the casing, and a die. Tightening bolts are "hidden" to entire height in upper housing. Length of holes for bolts is determined by length of bolt plus value of its displacement depending on diameter of wire.
EFFECT: technical result of the invention is use of non-magnetic materials when making the clamping body, clamping dies, protection of bolts and nuts, which allowed to avoid losses on remagnetization and crown as minimum in 4 times.
