New Tray Cable for Wind Turbines

Designed for applications with long-term cold exposure.

A new cable from Lapp meets UL-1277 tray cable requirements, as well UL-2277 requirements for 1000V Wind Turbine Tray Cable (WTTC). In addition, it provides industry-leading oil resistance and cold temperature performance. It is also rated as a CSA tray cable (CSA C22.2 No. 230).

OLFLEX FORTIS meets UL’s OIL RES I & II as well as UL AWM 21098, allowing application in environments with long-term oil exposure. The cable has FT4 flammability resistance and passes the same crush and impact tests as armored Metal Clad (MC) cables. The combination of outstanding oil resistance, mechanical toughness and tray rating allows it to be used on machine tools, cable trays, and exposed runs between machines and trays. The oil resistance factor makes FORTIS valuable for use in wind turbine nacelles, and the cable’s torsion resistance is an excellent fit for application in wind turbine towers.

OLFLEX FORTIS’ excellent cold-temperature toughness and flexibility make it perfect for refrigeration projects or cold-weather installations, even in arctic climates. The cable uses fine conductor strands for superior flexibility during installation and for use in applications with limited motion, like the torsion movement of cables in wind turbine towers. The copper core is sized for dual-rating to North American (UL) and European (VDE) standards.
