P4 RFOU/TFOU 8.7/15kV Offshore Cable
P4 RFOU/TFOU 8.7/15kV Offshore Cable Application
P4 RFOU/TFOU 8.7/15kV Offshore Cables are partially water blocked, flame retardant, low smoke, halogen free and mud resistant, used for fixed installation for medium voltage power.
These P4 RFOU/TFOU 8.7/15kV cables are flame retardant, low smoke, halogen free and mud resistant. This Cable is intended for fixed installation for energy transmission or power feeder with a rated voltage of 6/10KV. These cables can be installed on drilling ships, drilling platforms ( jack up, semi-submersible), Production Platforms ( TLP, semi-submersible, SPAR, fixed platforms) and FPSO/FSO.
