Finishing overhead power cable is not just a manufacturing step. It is a reliability decision. When these cables face extreme weather, long spans and critical loads, surface quality becomes directly linked to long term performance.
That is where the high levels of process control associated with the automatic Vapormatt Profelis wet blasting machine make a big difference. Consistent surface preparation helps ensure safer handling, predictable electrical performance and higher confidence in the final installation.
A few reasons this level of control matters:
• It supports stable and repeatable surface roughness, which is essential for producing a non-specular surface with high emissivity (also known as surface de-glaring).
• It helps prevent defects that can lead to premature wear when cables are exposed to vibration and environmental stress.
• It allows teams to maintain quality at scale, rather than relying on individual operator judgement.
• It strengthens traceability, giving manufacturers clearer insight into each stage of production.
For organisations delivering infrastructure that must perform for decades, these gains are vital. They shape reliability, safety and cost efficiency.
