A 5% increase in current carrying capacity...

A 5% increase in current carrying capacity. Same conductor. Same cross-section.

It comes from the surface finish alone.

Wet blasting raises aluminium conductor emissivity from approximately 0.5 to 0.8, increasing heat dissipation at the same operating temperature and delivering measurably greater ampacity. It also meets ASTM B979 in a single inline pass, with no secondary cleaning required before reeling.

Dry blasting can achieve the same specification, but wet blasting achieves it without airborne dust and related operator health risks, contamination of the finished conductor, and with a more consistent / uniform finish.

Vapormatt has supplied inline finishing systems (mainly our Porfelis automatic wet blasting machine), to overhead conductor manufacturers across North America and Europe for over fifteen years. If you're specifying conductor finishing equipment, we would be glad to discuss your requirements and arrange a sample trial.
