Fixed coupling – ‘’Tr’’ type

.


Category:

Intended use: construction of fixed, permanent points for the assembly of phase clamps of short-circuiting devices in high / medium voltage stations, on round cross-section conductors for the improvement of mounting conditions for the short-circuiting devices.

Assembly method: manually, at height, during the overhaul works, with the de-energisation of the installation. The application is performed on flexible multicore conductors or round cross-section rigid bars, with appropriate tools that allow the firm tightening of the conductor coupling and in strict observance of the mounting instructions.
