SeaLine® Cat cables

Fire resistant cables Cat 6A (PH 120+)

The ship and offshore market requires more and more cables with functional integrity during fire influence. These cables must have the capability to transfer all necessary power or signals even during fire influence. LEONI has designed several different cable types that will be able to transmit the data characteristics of Cat 6, Cat 6A or Cat 7 in standard use. The Cat 6A cable also transmits the data characteristics in case of fire and afterwards.
The cable was designed in accordance to the requirements of the IEC 60093-350 standard for fire-resistant cables and is similar to the standard design of data transmission cables.

Cable design:

The insulation of the single core must be involved a combined (hybrid) design of an electrical insulation part of extruded thermoplastic material and a fire-resistant second layer. In the LEONI design, it is a polyethylene inner skin directly extruded on the copper wire and a number of fire-resistant mica tapes, which are wrapped around the thermoplastic insulation.
