Neutral supported cables are intended for use either as a service drop cable betweena power pole and the service entrance, or as a secondary distribution cable betweenpoles. Their use is limited to circuits not exceeding 600 volts phasetophase.Duplex and triplex service drop cables are intended to deliver singlephase power fromthe secondary power line or polemounted transformer to the service entranceconductors at the user’s building or other structures. Quadruplex service drop cable isintended to deliver threephase power from the secondary power line or polemountedtransformer to the service entrance conductors at the user’s building or other structure.Optional construction includes an insulated control/supply conductor.Cables supplied with an optional ?ame retardant PVC jacket over the insulation aresuitable for applications requiring an FT1 rating.
