优选的，所述防氧化层为镀锌层。
优选的，所述第二耐热层为聚酯亚胺层。
优选的，所述绝缘漆层为氟化聚乙烯层，且绝缘漆层的外壁上均开设有散热通孔。
优选的，所述屏蔽层由铜丝和涤纶棉线交织而成。
优选的，所述中空内管的内壁上粘接有碳纤维保护层。
与现有技术相比，本发明的有益效果是：一种耐热性PE电力管，由于设置有第一耐热层，耐高温漆包线和耐高温铁丝网，并且耐高温铁丝网上设置有石英填充层，相比于原有PE电力管耐热性更好，由于第二耐热层为聚酯亚胺层，更加提高了PE电力管的耐热性，由于绝缘漆层为氟化聚乙烯层，提高了PE电力管的绝缘性，由于防氧化层为镀锌层，能更有效的防止电力管氧化。
附图说明
图1为本发明结构示意图；
图2为本发明耐高温铁丝网示意图。
图中：1电力管外壳、2防氧化层、3第一耐热层、4屏蔽层、5第二耐热层、6绝缘漆层、7中空内管、8耐高温漆包线、9耐高温铁丝网、10网格、11石英填充层。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1-2，本发明提供一种技术方案：一种耐热性PE电力管，包括电力管外壳1，防氧化层2，第一耐热层3，屏蔽层4，第二耐热层5，绝缘漆层6，中空内管7，耐高温漆包线8，耐高温铁丝网9，网格10，石英填充层11，所述电力管外壳1内侧设置有防氧化层2，所述防氧化层2内侧设置有第一耐热层3，所述第一耐热层3内侧设置有耐高温铁丝网9，所述耐高温铁丝网9上均匀设置有网格10，所述网格10的内腔设置有石英填充层11，所述耐高温铁丝网9内侧设置有耐高温漆包线8，所述耐高温漆包线8内侧设置有屏蔽层4，所述屏蔽层4内侧设置有第二耐热层5，所述第二耐热层5内侧设置有绝缘漆层6，所述绝缘漆层6内侧设置有中空内管7。
其中，所述防氧化层2为镀锌层，所述第二耐热层5为聚酯亚胺层，所述绝缘漆层6为氟化聚乙烯层，且绝缘漆层6的外壁上均开设有散热通孔，所述屏蔽层4由铜丝和涤纶棉线交织而成，所述中空内管7的内壁上粘接有碳纤维保护层。
工作原理：在使用过程中，中空内管7内部电缆如果有短路的情况，绝缘漆层6能够有效的绝缘，第二耐热层5能够完全阻挡热量在电力管内部，即使第二耐热层5受到损伤，耐高温漆包线8和耐高温铁丝网9上的石英填充层11也能对热量进行阻挡，即使耐高温漆包线8和耐高温铁丝网9上的石英填充层11，第一耐热层3也能对热量进行阻挡。
