Quadruplex Unjacketed Overhead Neutral Supported Cable Description
The insulated conductors of NS75/NS90 Service Drop Cables are resistant to weathering, sunlight, abrasion, tearing, cutting and chemicals. The cable is rated 600 V with a maximum conductor operating temperature of 90°C for Cross-linked Polyethylene insulation, which allows for higher ampacity compared to NS75 cable.
Quadruplex Unjacketed Overhead Neutral Supported Cable Application
Duplex and Triplex NS75/NS90 Service Drop Cable is intended to deliver single phase power from the secondary overhead power line or polemounted transformer to the service entrance conductors at the user’s building or other structure.
Quadruplex NS75/NS90 Service Drop Cable is intended to deliver three phase power from the secondary overhead power line or pole-mounted transformers to the service entrance conductors at the user’s building or other structure. NS75/NS90 cable may also be used as pole line secondary with service splices at the pole (also refer to CEC rule 12-318). NS75/NS90 cable is rated for use on systems having nominal voltages of 600 V or less.
