NS75/NS90 Duplex Unjacketed Overhead Neutral Supported Cable

The NS75/NS90 Duplex Unjacketed Overhead Neutral Supported Cable is designed for use as an overhead neutral conductor in electrical distribution systems. It consists of two unjacketed conductors, typically aluminum or copper, supported overhead for reliable connection and support. The design is optimized for overhead installation, providing a lightweight, flexible solution that can withstand environmental exposure such as UV radiation, wind, and temperature variations. The NS75 and NS90 designations refer to the conductor sizes, with NS75 being smaller than NS90, suitable for different load or current capacity requirements. This cable is used in utility and industrial applications to ensure a safe, durable overhead neutral connection.

Duplex 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.

Duplex 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.

Duplex Unjacketed Overhead Neutral Supported Cable Standards

NS75/NS90 cables meet or exceed the following standards
