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.
„T” fixed coupling types:
– „T55” fixed clamp for rigid round bars with a diameter of 55 m
– „T80” fixed clamp for rigid round bars with a diameter of 80 mm
Components:
-Body – 1 piece
-Cap – 1 piece
-Fittings – 2 sets
