Tension clamp JR-85
Jera has researched a wide range of tension clamps for Medium Voltage and High voltage overhead lines with ABC, AAAC, ACSR, ACSS cable systems with voltage 6-35kV. For Overhead Transmission line, one of the most critical decisions involves in selecting the proper string hardware to correspond to the requirements of tension load and duration of usage.
Tension clamp JR-85, is used on the dead ends or passing overhead bare and covered conductors on 6-35kV power lines, conductor size 25-150 mm2, minimal breaking load 35 kN.
Conductor size, mm2
Tightening torque, N*m
Tension clamp body is made of corrosion resistant aluminum alloy, done by casting technology, that guarantee its high strength characteristics, to withhold the static or dynamic loads. Hardware are hot dip galvanized steel.
In pistol grip clamp is applied close-pin solution, which eliminates the risk of failure of high voltage electric power transmission line from wind movement, vibrations. The covered cable has to be peeled off before installation.
Jera line is able to produce other pistol grip, tension and suspension fittings, and pole line hardware for 6-35 kV electrical power lines, according to customers’ drawings and special requirements.
Typical line hardware system is applied by using dead end strain clamp, socket eye, socket clevis, U-bolt, link single plate, link fitting, anchor shackles, which are available in Jera high voltage accessories product case. All the assembly of link fitting passed temperature cycling and aging tests, corrosion resistance test, tension test.
Jera’s assortment of high-voltage fittings and pole accessories is constantly expanding. We are focus on the quality and on the completed solutions for our customers.
