The line represents one of the Pourtier product core business.The machine is composed of six cages together with the latest development in terms of large high pulling force capstans of 80t.Each cage is provided with automatic bobbins loading system and protected by a soundproof cabinet in order to guarantee 80dB noise level that fulfills the EU standards for production environments.

The line guarantees an efficient and effective production process thanks to several accessories like yarn binders, longitudinal taping heads, rotating compacting heads whose efficiency is ensured using dedicated jib cranes. The line has been developed to produce round, sectoral conductors both copper or aluminum with a cross section up to 4,000mm².

A dedicate bobbins braking system has been developed in order to guarantee a wide wire diameter range that is necessary to produce the full cross section range. This line is highly customized and developed in accordance to all the production and maintenance customers’ processes to satisfy all their needs in the best possible way. Moreover, all safety requirements are of course implemented to guarantee a perfectly safe and reliable production process.
