Transmission Pole ID Signs

Overview

Protecting people and powerlines. Safety through clear identification.

Faded pole IDs were becoming a serious hazard across SA Power’s network.

Crews were operating close to transmission poles without clear identification, increasing the risk of accidental contact and driving up maintenance costs due to frequent replacements.

Identimark partnered with the client to deliver U3 signage with 32+ year durability and enhanced night visibility - helping field teams work safely, efficiently, and confidently around high-voltage assets.

U3 signage life expectancy of 32+ years

Eliminated need for frequent replacements

Glow-in-the-dark safety strip added for night visibility

Custom packaging and guidance sped up installation

Reduced long-term maintenance costs for network operators

Challenge

What needed to be solved.

Transmission poles must be clearly marked to ensure safety and efficient asset identification.

SA Power was replacing ID signs far more frequently than planned due to rapid fading and UV damage. This not only increased labour and material costs, but also posed a safety risk for workers operating near live conductors without proper visual cues..

Key challenges included:

Fast-fading signs: Harsh climate conditions caused premature deterioration.

Safety risk to crews: Unmarked or unclear poles created confusion and potential danger.

Labour inefficiency: Frequent re-installs consumed time and resources.

Identimark worked closely with SA Power to trial and select U3 signage for transmission poles. Built for high UV environments and engineered to last over 32 years, the signs also featured a luminous strip to support night-time visibility. Installation was simplified using SMP60 adhesive and custom packaging, allowing field teams to apply signs safely and efficiently without specialised tools or delays.

This upgrade helped SA Power protect its teams and infrastructure with smarter, longer-lasting solutions—and freed up maintenance crews to focus on higher-priority tasks.

Key solutions included:
