摘要：
Electric cables insulated with a cured polyolefin and having high electrical breakdown strength are produced, in each instance, by applying, an insulating layer of polyolefin containing a curing agent onto a conductor by means of an extruder, forming and hot-curing said layer by means of a long-land die, simultaneously applying a specific forming coagent to a tapered portion of the long-land die, and cooling the resulting hot-cured insulating layer formed on the conductor in a cooling zone.
