P18 RU Unarmored Offshore Cable 0.6/1Kv
P18 RU Unarmored Offshore Cable 0.6/1Kv Application
P18 RU Unarmored Offshore Cable 0.6/1Kv is used for fixed installation on offshore units in all locations except where there are mud projections. P18 RU type meets IEC 60332-3-22 fire test on bunched cables.
All materials used to manufacture this cable are halogen-free. This design ensures that non-corrosive and low toxic gas in case of fire. These P18 RU cables can be installed on drilling ships, drilling platforms ( jack up, semi-submersible), Production Platforms ( TLP, semi-submersible, SPAR, fixed platforms) and FPSO/FSO.
