在本实用新型的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制；术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性，此外，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本实用新型中的具体含义。
参照图1-3，本实用新型提供的一种实施例：一种新型耐高温电缆，包括外层护套2，外层护套2的套身上固定套设有防火涂层1，外层护套2的内部固定套设有防火套3，具有防火耐高温性能，防火套3的内部固定套设有隔热层12，隔热层12的内部固定套设有加强护套4，加强护套4的内部固定套设有二号阻水层11，二号阻水层11的内部固定套设有铜丝屏蔽层5，铜丝屏蔽层5的内部固定套设有一号阻水层10，一号阻水层10和二号阻水层11起到阻水和保护铜丝屏蔽层5的作用，一号阻水层10的内部固定套设有绝缘屏蔽层6，绝缘屏蔽层6起到绝缘的作用，绝缘屏蔽层6的内部固定套设有绝缘层9，绝缘层9的内部固定套设有导体屏蔽层7，导体屏蔽层7用于屏蔽电力导体8，导体屏蔽层7的内部固定套设有电力导体8。
加强护套4是由铝合金材料制成，铝合金材料韧性强并且具有良好的散热性能，使得该电缆更加耐用和稳定，防火套3是由一股云母带13和一股铝合金带14编织而成，加强其耐高温性和稳定性，防火涂层1是由电缆防火涂料构成，防火涂层1用于防止外界明火入侵，隔热层12是由3M隔热膜构成，具有较强的隔热性能，防火套3设置成圆环形形状，一号阻水层10和二号阻水层11厚度相同，铜丝屏蔽层5是由多根铜丝编织而成。
工作原理：在使用该新型耐高温电缆的时候，如果电缆遇到明火会被防火涂层1阻燃，能够有效的防止电缆被明火危害，当该电缆处在高温环境中时云母带13能够有效的起到耐高温性，同时高温会被隔热层12阻挡在外，防止高温入侵电缆内部，并且由于加强护套4和铝合金带14都是由铝合金材料制成，所以电缆承受的高温很快会被散发出去，从而起到防止电缆持续高温叠加，进而使得该电缆更加耐用。
最后应说明的是：以上所述仅为本实用新型的优选实施例而已，并不用 于限制本实用新型，尽管参照前述实施例对本实用新型进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
