Insulation
Okonite insulation is a heat, moisture and chemical resistant, mechanically
rugged compound. The insulation thickness for size #14 AWG through #9 AWG is
5/64" and for #6 AWG through #2 AWG is 6/64". One conductor in each layer is
identified by color coding. In addition, each conductor is number coded for
ease of identification.
Assembly and Finish
Individual conductors are assembled with suitable fillers, where necessary,
and a taped cushion layer. A 7 mil flat copper alloy tape is then helically
applied, giving outstanding mechanical protection. The black Okolene®
(polyethylene) jacket is then applied overall.
Applications
Okonite Armored Underground Signal Cables are designed for use in all vital
railroad signal circuits where security of service and long life are
required in all vital circuit and safety related applications. These cables
are recommended for use where crush resistance, termite and rodent
protection are considerations and in all wet and dry locations.
