General:
Tension clamps of the hexagonal compression type represent the best practical solution for connecting the high voltage transmission line conductors to the tower, because they can handle maximum mechanical tension of the span and it is assured that electrical continuity of the conductor in joints and in the passage through the dead end jumper connection assembly as well. In fact the electrical conductivity measured at the ends of compression accessories is always higher than the one measured at the ends of a conductor part of equal length.
Holding forces:
Our tension clamps design shall take up the maximum conductor strain, means shall take up the holding forces stipulated in the regulations, which as a rule lay 95 % of the ultimate conductor strength.
Vibration:
Vibration of the Conductor is dangerous, especially at the Conductor entrance of the clamp. Safety requirements can be acquire by a light weight construction of the clamp and a trumpet shape of the termination which represent a gradual increase of Conductor compression.
Corona and RIV:
Good corona and radio interference voltage (RIV) behavior due to rounded shapes.
Short circuit withstand capability:
The short circuit withstand capability is excellent due to a narrow ranged groove which leads to a large contact areas. The connecting parts of the clamps are adjusted to suit requirements.
Corrosion resistance:
Maximum corrosion resistance is achieved by using a clamp material that matches with that of the Conductors.
Tailored design:
To achieve the best result of the compression strength the clamp are individually design and adapted for each type of Conductor based on its identification code, material, cross section, number and diameter of wires and also ultimate tensile strength (UTS).
Instruction for assembly and compression:
Shall be according to details of the manufacturer instruction.
