Seals for high voltage environments

Seals for high voltage environments

Power transmission and distribution specialist Joulz BV has realized a 150 kV substation in Ypenburg, the Netherlands, as an extension of the national grid.

Safety in every component

Joulz BV focused on safety, reliability and redundancy. They chose Roxtec out of experience – and to be able to guarantee water-tightness.

Problem-solving services

The adaptable sealing modules helped Joulz BV handle a sudden design change, which forced them to route and seal cables of another dimension than planned.

Thanks to the flexibility of Roxtec, we were able to handle the changes without problems.
