The present paper describes a process developed several years ago, and which ensures very low permittivity factors hand in hand with high dielectric strength and good mechanical resistance. Process control is easy and accurate, and uniform results can be obtained throughout an indefinte series of batches. The insulation obtained is referred to in France as tubular balloon insulation or more briefly, balloon insulation. The term is descriptive of the final result, which is reminiscent of a string of small balloons attached together. The insulation is attained by extrusion around the conductor of a polyethylene tube with an inner diameter that is greater than the wire section the conductor is centered in the tube by crimps at regular intervals.
