The right way for Fitting Systems Manufacturing - Laboratory
Damping Systems
The following tests to be performed on Spacer Dampers and Vibration Dampers are carried out in our laboratory that is properly equipped for this purpose: • • • •
Fatigue test Simulation of short circuit Slippage of clamps Verification of damping performances
Salvi is a Company specialized in designing, manufacturing and testing products for High and Extra High Voltage Overhead Transmission Lines. • Hardware, fittings and Accessories for OHTL from 11 kV up to 1,200 kV (Conductors, Shield wires and OPGW cables) • Damping Systems (Spacer Dampers and Vibration Dampers defined through a specific dedicated study) • Guy wire anchor devices
Manufacturing activities are carried out directly in our workshop or through our Italian sub-suppliers/partners.
Complete assembly of spacer dampers and Vibration Dampers is carried out by Salvi with automatic assembly lines.

An optimum Damping Systems is designed through an analytical evaluation of the vibration phenomena of each OHTL, by means of a damping study, carried out with a validated software and based on the characteristic of each T/Lines such as:
Type of conductor (stranding, diameter, mass per unit length), bundle spacing (400 mm, 450 mm, 500 mm etc), tensile load at the coldest period of the year, EDS, span lengths and environmental conditions (type of terrain and wind speed records). Design of Damping Systems is always carried out by highly professional staff in close cooperation with the Department of Mechanical Engineering of the Politecnico di Milano.
