Dura-Line pre-lubricated TornadoPlus duct

Click2Contact

The Dura-Line pre-lubricated TornadoPlus duct is designed to facilitate faster optical fibre cable blowing for faster cable installation.

The duct’s design creates an ‘air-cushion tornado’ effect, imparting an increased pulling force on the cable. As the cable rides on the air cushion and does not touch the duct, friction is reduced, enabling up to two times longer cable blowing per operation, compared to conventional smoothwall ducts, thereby lowering cable installation costs.

Along with its consistent and faster blowing speed and longer blowable lengths in each shot, the duct requires a decreased amount of Figure-8 construction during blowing, saving time and reducing the chances of cables getting entangled.

The duct enables usage of longer cable lengths/drums, hence fewer splices and improved daily output of blowing, resulting in faster network rollouts. There is lower stress on fibre and 30% lesser pulling force required than in manual cable install.

An optional integral detectable cable tracer wire negates the need for separate additional wire or tape.

Various colours and custom printing are available.
