Tensorex C+ : advantages and markets

TENSIONING DEVICES

Very compact, small size a. Easy and fast handling from stock to installation site ( costs and industrial injury reduction ) b. Fast installation, 1 hour ( costs reduction ) c. It could be lifted up to the pole’s head by a tackle. No needs of crane d. Low visual impact ( appreciate in cities, rail stations, bridges .., crowded areas)

Device without weight

a. Free space at ground level around the pole ( free moving of people without risk ) b. Vandalism proof ( costs reduction )

Maintenance

a. No requested (maintenance costs reduction)

Accuracy a. Low hysteresis effect over pull [P] value. ( it keeps OHL in geometry, so good electrical contact

and wear reduction )

TENSIONING DEVICES

Purely mechanics a. It doesn’t need power supply or /and refill oil or gas. No influence from the temperature

variation

Safe and monitoring a. It’s possible to provide a monitoring system that read pull, position and temperature values

remote them to the office

TENSOREX ®

Tensorex® is a patented automatic tensioning device for maintaining constant the pull of railway contact wires and/or messenger wires, during their elongation or contraction, due to temperature variations along day and night, summer and winter.

TENSIONING DEVICES

TENSOREX ® Comparing with the traditional weight-tensioning-counter weight-, Tensorex® does not occupy space vertically or laterally, as it is installed overhead, in series to the wire.

One device only is suitable for a variety of span lengths and temperature variations.

TENSIONING DEVICES

TENSOREX ® Phantom Phantom is the evolution of Tensorex ® for the automatic tensioning for tramway and trolleybus catenary. Phantom can also be installed in railways station where automatic tensioning is needed in order to reduce the visual impact. Phantom is a Tensorex ® mounted vertically inside a street pole.
