Systems

CV systems for the cable insulation

Especially in cable production, the demands on quality and reliability are very high. Due to our decades of experience, we guarantee our customers needs-based and individual solutions at all times.

From the tower to the chain line and horizontal lines to the special design: Maschinenbau Scholz offers state-of-the-art programmes for the highest requirements. For this reason, we are one of the leading manufacturers in the cable industry with over 350 CV plants supplied for the production of low, medium and high voltage cables.

Each of our CV systems for the continuous vulcanisation / cross-linking of cables with rubber or cross-linkable polyethylene is a custom-made product. That is why it is our goal to fulfil every requirement of our customers down to the smallest detail. This also applies to services that are not explicitly listed in our delivery programme. Just ask us: we will take care of your wishes.

For complete solutions, we work together with our partner Supermac from India, among others.
