The cooling circulation of nitrogen shrinks the outer surface of the insulation, thereby forcing the insulated core into its round shape. This process enables a catenary line with moderate rotation to produce cables with thick walls.
Excellent roundness with outstanding concentricity, and the final cable material costs lowered by 6 - 7%.
