RISSB/AS Standards for 25 kV AC & Overhead Wiring: Harmonisation & State‑Specific Notes


“Harmonise 25 kV AC standards: Apply RISSB/AS rules and state notes for safe, compliant overhead wiring.”

About This Course

Australian rail electrification projects often struggle with fragmented standards for 25 kV AC overhead wiring systems. State-specific deviations from RISSB and AS guidelines create uncertainty, leading to design conflicts, commissioning delays, and costly rework. This course provides a clear roadmap for harmonising these standards and implementing consistent acceptance testing protocols.

Participants will learn how to interpret RISSB and AS requirements, reconcile state-specific variations, and apply harmonised criteria to design, construction, and commissioning phases. The course covers clearance rules, tensioning specifications, component selection, and acceptance evidence requirements—all aligned with best practice for interoperability and safety.

Key benefits include:

·        Compliance assurance: Avoid regulatory rejection by applying harmonised standards.

·        Risk reduction: Prevent delays and disputes caused by conflicting requirements.

·        Cost optimisation: Reduce rework and spare parts complexity through standardisation.

·        Operational reliability: Ensure consistent performance across multi-state networks.

Through real-world examples and decision frameworks, learners will gain practical skills to manage complexity and deliver projects on time and within budget. Whether you are designing new electrification systems or upgrading existing infrastructure, this course equips you with the knowledge to achieve harmonisation and compliance with confidence.
