People & Careers

With decades of history and recognized expertise,
the Transmission division is specialized in designing,
manufacturing and producing comprehensive ranges of
transmission lines and systems connectors, damping systems,
hardware and most advanced substation fitting solutions,
adapted to the most technical configurations such as 8-bundle
spacer dampers, UHV HVDC connectors and innovative
high temperature conductor’s accessories.

Damping Systems

Aeolian vibrations and sub-span oscillations are the adverse phenomena induced by wind action that shall be controlled in order to safeguard the life of the transmission lines. This is always the target of Salvi design of Damping Systems.

Two to eight bundle spacer dampers

The range of Salvi SD covers all possible applications: Voltage up to 1.200kV Bundle Spacing up to 1.200mm –

Any conductor types (ACSR, AAC, AAAC, ACAR) and clamping solutions.

Salvi expertise in R&D, design & test has and continues to assist Engineers, Consultants and Utilities globally,

with new types of spacer dampers for all type of configurations.

Vibration Dampers (VD)

In order to satisfy several demands of the market, our range of VD is very wide. It includes models with galvanized steel or melted Zamac masses and models with galvanized steel or stainless steel messenger cable.

Special products

Salvi is also specialised in executing projects which have a
high technological content which requires a highly qualified
internal organisation, cutting edge laboratory equipment
and a strict collaboration with Research Centres and
Universities. Few examples are shown hereunder.
