Type HTUA is a robust conduit with a galvanised steel core and a thick, smooth PVC cover. An integral grounding copper wire (till 1.1/4”) provides a high level of EMI/EMP shielding for cables that require a high degree of electromagnetic protection. Type HTUA is UL & CSA approved and is used to protect cables on transformers, generators, motors, actuators, valves, machinery, equipment, enclosures and installations exported to countries outside, but also inside Europe.
