Description
AC90
600 Volt XLPE insulation aluminum or steel interlocked armored cable
ACIC
300 or 600 Volt armored instrument and control cable. A CSA type designation used to describe
armored instrumentation and control cable. Available in either 300 Volt or 600 Volt with thermoset or
thermoplastic insulation, this cable can be supplied with an overall shield, shielded pairs, shielded triads
or unshielded in multi-conductor constructions from 2 to 72 conductors. The overall interlocked armor
and PVC jacket provide a (-40
