Power Transmission and Distribution Equipment

Delivering safe, reliable power has never been more essential. That’s why power utilities, manufacturers, specifiers and Authorities Having Jurisdiction (AHJs) turn to Intertek.

Our assurance, testing, inspection, and certification services help deliver dependable power transmission and distribution across industrial, commercial, and residential environments.
Intertek drives quality and efficiency throughout the entire Transmission and Distribution lifecycle. With local experts in medium- and high-voltage systems – and the backing of engineering insight and environmental advisory – we help keep power networks running safely, reliably, and without interruption.

Product range certification, combined with testing at in-house laboratories, reduces costs associated with prototypes, travel, and external testing. This, in turn, lowers CO₂ emissions and the overall carbon footprint, making a meaningful contribution to the sustainable certification of products.
