The worldwide proven Click-Fit locking mechanism prevents cable movement within the stress control body caused by thermo-mechanical forces, thereby ensuring a reliable and fail-safe connection during operation.

Transition Joints and Accessories for Fluid Filled Cables

These accessories are available from 69 kV to 400 kV and include: High Pressure Fluid Filled Transition Joints; SCFF/LPOF Transition Joints; Fluid Filled Pressure Tanks; PFT Solutions.

SPEED™ line joints

The SPEED™ line joints are based on ethylene propylene rubber (EPR) and cold-shrink technologies and are designed to connect two HV extruded cables in a fast and reliable way. SPEED joints are based on cold-shrink techniques (factory-expanded on carrier tubes) and are available up to 123kV Um. Prysmian’s SPEED line one-piece, premolded joint sleeves are completely manufactured in-house. Each single joint sleeve is mechanically and electrically routine tested in the factory, according to the applicable standards. All products are available in both straight and sectionalized options.

Environmentally Friendly Products

In line with the Prysmian’s sustainability targets and ambition, our newest HV accessories are all developed to be sustainable and environmentally friendly. Up to 170kV, there is now a complete portfolio of components available that are fully dry-type solutions that do not require any fluid- or gas-filled components.
