About This Item
IEEE 2789-2025 is an approved draft guide for the selection and application of cables used in enclosed transit infrastructure. It addresses the practical needs of power, energy, and transportation environments where cable choice can affect reliability, installation quality, and ongoing service performance. By focusing on enclosed transit settings, this standard helps engineers and buyers consider cable characteristics in relation to confined spaces, system demands, and operational constraints.
IEEE 2789-2025 overview
This technical document provides guidance for choosing and applying cables in enclosed transit infrastructure, where electrical distribution and transportation systems must work together under controlled but demanding conditions. IEEE 2789-2025 is relevant to cable design decisions, routing considerations, and application practices that support consistent performance. It is especially useful where cable selection must account for the interface between power systems and transit equipment, along with the practical limits of enclosed installations.
Typical use cases
The standard is commonly consulted for cable specification in enclosed rail transit tunnels, station support systems, and related infrastructure where electrical continuity and installation constraints matter. It may also support procurement and engineering review for traction power, auxiliary power, control circuits, and other cable applications within transportation facilities. In these environments, the guide can help align cable selection with the needs of enclosed routes, fixed installations, and system integration.
Why this standard matters
IEEE 2789-2025 matters because cable selection in enclosed transit infrastructure can directly affect safety, maintainability, and system reliability. Clear guidance helps reduce risk during design, purchasing, installation, and inspection by promoting more consistent application choices. For owners and engineers, it can also support better coordination between performance expectations and the practical realities of enclosed transportation environments. Using a defined guide may improve compliance efforts and reduce avoidable installation errors.
