Apparatus and method for the analysis of a stream of molten polymer for the presence of unwanted voids, gels and particles of solids by observation of the stream, utilizing an observation probe and an illuminating probe placed at an illuminating angle to the observation probe so as to establish an image observable at an observation point remote from the stream.

Electrical cables that carry higher voltage require insulation of greater thickness. This invention extrudes the insulation over a cable core and extrudes it in superimposed layers which fuse to one another to prevent formation of voids within the insulation. The insulation applied in each superimposed layer increases the impulse breakdown stress in volts per mil of insulation thickness. A high voltage cable for any given voltage can, therefore, have a thinner insulation if the insulation is applied in layers according to this invention instead of being applied in a single layer in accordance with the practice of the prior art.
