摘要： Curable polyolefin insulating material covering an electric cable core is continuously cured as it is drawn through a horizontal curing tube constituted of a number of units each composed of heating and cooling zones and a seal portion provided to separate one unit from another, the curing tube being filled with a high-viscosity heat transfer liquid. At each seal portion, the heat transfer liquid is super-cooled and increases its viscosity enough to seal the clearance between the outer surface of the insulated cable core and the inner wall surface of the curing tube to support the cable core with the least dip. This apparatus can improve production efficiency, and the finished product is free of any eccentricity or distortion of its shape.

摘要： An electric power cable line is arranged in which the insulating layer is increased to a greater thickness at two end portions of each cable than a thickness at the other or center portion of the same. Since the insulating layer is increased in thickness at the end portions of the cable, thus an electrical stress exerted on the overall layer construction of the end portions is lowered. Hence, the dielectric strength of the end portions of the cable becomes high and the power cable line will thus be increased in the operational reliability.
摘要翻译： 布置电力电缆线，其中绝缘层在每个电缆的两个端部处比在其另一个或中心部分处的厚度增加到更大的厚度。 由于绝缘层在电缆的端部处的厚度增加，因此施加在端部的整个层结构上的电应力降低。 因此，电缆的端部的介电强度变高，因此电力电缆线的操作可靠性将增加。
