Fiberglass composites perform excellently in overhead contact line suspension systems for public transportation with nominal power ratings of up to 3 kV.

These systems have been in use for many years now in such cities as Milan, Turin, Genoa, and Naples.

Fiberglass line supports and tensioners are an effective and economical alternative to the traditional system of steel line supports with insulators, and offer savings of approximately 70%.

Electrical insulation, mechanical strength, almost total absence of maintenance, and ease of handling and installation are the features that dictate the choice of pultruded fiberglass profiles.
