Triple Crosshead

Royle's triple crossheads for MV and EHV applications contain many key features that have enabled them to be well proven in installations worldwide. All of the features are intended to promote product quality and integrity, to maximize the length of production runs, and to ensure operator ‘ease of use.' The internal flow distribution channels have been designed with the assistance of computer simulation models, but designs have been empirically enhanced as a result of actual process experiences.

A key objective in the design of Royle's family of triple crossheads is to minimize compound stress within the head. This has been achieved through careful balancing of the frictional flow paths of each polymer, strategic use of electric heaters in combination with oil circulation for heating and cooling for close temperature control, and complete separation of all three extruded layers until each is applied directly to the conductor or cable surface. Royle's triple heads are well proven in service in manufacturing cables to the latest AEIC and IEC specifications.
