带非线性屏蔽层的高压、超高压交联聚乙烯绝缘电力电缆
摘要：
带非线性屏蔽层的高压、超高压交联聚乙烯绝缘电力电缆，它属于电力传输领域，具体涉及一种高压、超高压交联聚乙烯绝缘电力电缆。本发明解决了已有的高压、超高压电力电缆因电树枝生成导致交联聚乙烯绝缘性能劣化进而破坏的问题。带非线性屏蔽层的高压、超高压交联聚乙烯绝缘电力电缆，它的内非线性屏蔽层挤压包覆在内半导电屏蔽层和交联聚乙烯绝缘层之间，并将内半导电屏蔽层和交联聚乙烯绝缘层隔开，外非线性屏蔽层挤压包覆在交联聚乙烯绝缘层和外半导电屏蔽层之间，并将交联聚乙烯绝缘层和外半导电屏蔽层隔开。本发明适用于各种需要高压、超高压电力传输的场合。
摘要（英）：

The present invention discloses a high voltage and ultrahigh voltage crosslinked polyethylene insulating power cable with non-linear shielding layer, which belongs to power transmission field and specifically relates to a high voltage and ultrahigh voltage crosslinked polyethylene insulating power cable. Problem of crosslinked polyethylene insulating performance deterioration and then destructionmade by generation of electrical tree of existing high voltage and ultrahigh voltage power cable is solved through the invention. The inner non-linear shielding layer of the high voltage and ultrahigh voltage crosslinked polyethylene insulating power cable with non-linear shielding layer is extruded and covered between inner conductor shielding layer and crosslinked polyethylene insulating layer,and separates inner conductor shielding layer with crosslinked polyethylene insulating layer. The present invention can be applied on all occasions that demand high voltage and ultrahigh voltage power transmission.
