Interlocked Armor Power Cable - 350 MCM - 3 Conductor - 5kV/8kV

The Interlocked Armor Power Cable – 350MCM - 3 Conductor - 5KV/8KV employs three conductors made from soft bare annealed copper available in compressed or compact stranding.  The copper conductors meet ASTM requirements B-3 for class B copper wire, B-8 for compressed stranded and B-496 for compact stranded conductors. The conductors are individually insulated with ethylene propylene rubber (EPR) per ICEA S-96-659.  A soft bare annealed copper grounding conductor is included in the assembly which helps to ensure steady conductivity throughout the life of the cable.  The exterior armor of the cable is an aluminum interlocked tape armor that is also available in galvanized steel.  The armor serves as the first line of defense against materials or objects that may pose a threat to the conductors.  The armor is coated with a yellow sunlight-resistant PVC jacket.

The Interlocked Armor Power Cable – 350MCM - 3 Conductor - 5KV/8KV is a wide-diameter cable designed to transmit medium voltages at a maximum conductor temperature of 105°C.  In emergency overload conditions, conductor can tolerate temperatures up to 140°C and in short circuit conditions, the conductor can tolerate temperatures up to 250°C.  The cable is approved for use in wet or dry locations and can be installed indoors or outdoors.  The cable can be installed aerially, in ducts, cable trays, conduits, or direct burial for circuits not exceeding 5,000 volts.  The cable is approved for use in hazardous locations in accordance with National Electric Code.
