Table 1-8.Types and Construction/Description of Shipboard CableContinued
Three conductors, special purpose, shielded: rubber insulation, overall braided
shield, polychloroprene or chlorosulfonated polyethylene jacket.
Singles, shielded: polyethylene insulation, braided shield on each conductor, arctic
type polychloroprene jacket.
Pairs, shielded, watertight, flexible: polyethylene insulation, braided shield over
each pair, arctic type polychloroprene jacket.
Five conductors, shielded, sonar: rubber insulation, braided shield on one conductor
only, and a braided shield over the assembled five conductors, polychloroprene
Seven conductors, shieled: rubber insulation, overall braided shield, polychloroprene
or chlorosulfonated polyethylene jacket.

The order of listing of cables for general application data has no significant meaning for their usage.
Many cables are manufactured in variations of armored, unarmored, and unarmored with overall
Table 1-10 provides data on the allowable temperature ratings and current-carrying capacities (in
amperes) of some single copper conductors in free air at a maximum ambient temperature of 86º F (30º
C). With temperatures greater than 86º F, the current-carrying capacity would be less.
