Leoni, the leading European provider of optical technologies, cables and cable systems to the automotive sector and other industries, has developed one X-linked jacket material to simplify the cabling of major projects thereby saving up to 75% of the cabling costs.

Major projects include a high complexity of regulations, cable types and installation and handling requirements. To simplify the handling of major projects’ Leoni has developed one X-linked jacket material for almost any cable type, meaning one jacket material fits all requirements – no multiple installation of cables:

LEONI X-Linked COmpound (LE.X.CO).

These advanced and unique X-linked jacket materials are designed to comply with requirements for offshore, railway, industry, marine applications and highly challenging environmental conditions. The cables comply with all requirements of any subsection of large-scaled projects, are available with various and customized cable designs and protection measures (armour, rodent and water protection, assembly options, fire retardant and fire resistant) They reduce planning and installation process preparation and are suitable for a wide range of challenging environmental factors (i.e. Jacket type SHF 2 according to IEC60092-360, MUD-resistant according to NEK606).

Benefits for handling major projects

LE.X.CO significantly reduces total costs of ownership due to simpler cable installation, improved tender comparability and easier handling of project management for the various areas of major projects management. All possible cable designs, including hybrid cables can be realized and there is no limitation of fiber or cable diameter. The assembly and splicing of LE.X.CO cabling is identical to standardized cable types.
