Industry challenge
The mass transit, energy & utilities pressure point.
Energy networks and mass transit systems operate in demanding physical environments where standard commercial-grade infrastructure is simply not fit for purpose. Cabling and passive components must withstand temperature extremes, vibration, EMI interference, and in many cases classified installation conditions. Procurement is further complicated by long project timescales, stringent compliance frameworks, and the need for full supply chain traceability. Sourcing partners who understand the sector, and can document provenance, are rare.
