摘要： The present invention is an improved power cable construction.Through the use of a multi-ply insulation layer, the resulting power cable retains the water tree or electrical tree resistance of generally-used tree-retardant power cables even though a conventional polymer insulation composition substantially replaces the tree-retardant polymer composition. An improved process that takes advantages of the multi-ply system is also taught.

摘要： TRXLPE-type cable sheaths are prepared by a method in which a solid polymer is mixed with a liquid water tree-resistant agent either by dosing or direct injection. In the dosing method, the solid polymer, e.g., high pressure LDPE, is sprayed or otherwise contacted with the liquid agent, e.g., PEG, the agent is allowed to absorb into the polymer, and the polymer with absorbed agent is then fed to an extrusion apparatus for extrusion over a sheathed or unsheathed wire or optic fiber. In the direct injection method, the solid polymer is first fed to an extrusion apparatus, and the liquid agent is sprayed or otherwise contacted with the polymer before the two are blended with one another through the action of the mixing elements of the apparatus.
