aluminium alloy
Additional informationThese straight compression lugs are used to establish current carrying, non-tensioned connections of AAC, AAAC, ACSR and AACSR to switch gears and in jumpers of overhead lines. For connecting conductors, two compression lugs are necessary. It is possible to connect conductors having both equal as well as different cross sections. The bolt sets for the jumper connections are to be ordered separately.
Mechanical tasks
Connections through the compression lugs are not tension-proof.
Connections in jumpers must be made using screw sets or special screw sets with locking plates.
Observe the required torque in each case.
Electrical tasks
1. guiding the operating current
Fittings carrying the operating current of the conductor rope must not assume a higher temperature than the conductor rope itself when the highest permissible continuous current is flowing. Likewise, the voltage drop across the live connection must not be greater than that across a section of conductor of the same conductor section of the same length.
2. short-circuit current resistance
The fittings shall be so designed that they are not deformed by the highest short-circuit current stress to be expected deformed by the highest short-circuit current load and that they do not reach a temperature inadmissible reduction of their mechanical strength.
3. avoidance of partial discharges
The fittings shall be designed in such a way that, at the maximum permissible operating voltage, the tuft voltage is higher than the required values.
