Intended use: achievement of permanent fixed points for the assembly of phase clamps of short-circuiting devices in HV / MV substations, on round section conductors for the improvement of mounting conditions for the short-circuiting devices.
Assembly method: manually, at height, with the de-energisation of the installation. The application is performed on flexible multicore conductors or round section rigid bars.
„T” fixed points types:
-„Tr” – for flexible multicore conductors – sections between 185 and 680 mm2 (Ø19–36 mm)
-„T55” – for rigid round bars with a diameter of 55 mm
-„T80” – for rigid round bars with a diameter of 80 mm
Components:
- Body – 1 piece
- Cap – 1 piece
- Fittings – 2 sets
