It can be used in direct burial if installed with a ground conductor in close proximity. These cables are capable of operating continuously at the conductor temperature not in excess of 105°c for normal operation, 140°c for emergency overload, and 250°c for. Noark medium voltage power cables, which can be applied in either directly or indirectly buried duct, are suitable for continuous operation from 90°c to 105°c, wet or dry, and are sunlight.
Good Morning!! Join McK and Chels for more NEWW!!! Drop it like its hot
Cables may be installed in wet or dry locations in duct, cable. The cable is approved for temperatures up to 105°c and voltages up to 5000 volts in ungrounded. These cables are capable of operating continuously at the conductor temperature not in excess of 105°c for normal operation, 140°c for emergency overload, and 250°c for short circuit.
Suitable for installation in conduit, trays, troughs, ducts, aerial, and direct burial applications.
1) ampacities in air are based on nec 2017 table 310.60(c)(71), for insulated three conductor copper cable isolated in air, maximum conductor temperature of 105°c, ambient air.
