AS/NZS 2276.2:1998 (R2017) PDF Download

AS/NZS 2276.2:1998 (R2017) is a standard that outlines the requirements for feeder cable used in traffic signal installations, specifically for interconnecting vehicle detector equipment and inductive type vehicle detector loops. The cable is designed to operate in extra-low voltage (ELV) circuits and is meant to maintain a nominal characteristic impedance (Zc) of 90W at 50 kHz. It should also exhibit minimal changes in its characteristics when exposed to adverse environmental conditions.

The standard provides guidelines and specifications for the construction, materials, and performance of the feeder cable. It emphasizes the need for the cable to have a balanced-twisted configuration and to be adequately screened to minimize interference and ensure reliable signal transmission. The cable is intended to be used in traffic signal installations, where it will be subject to various environmental conditions and must withstand them without compromising its performance.

Appendix A of the standard provides purchasing guidelines, which can be helpful for procurement. These guidelines may offer additional specifications or considerations for selecting the appropriate feeder cable for traffic signal installations.
