OPGW Optical Fiber Ground Wire 24 Core Fiber Optic Cable

$1.00
简介 OPGW光缆(又称光纤复合架空地线)是敷设在架空高压输电线地线内,在输电线路上组成光纤通信网的一种光缆。这种结构形式兼具地线和通信双重功能,一般简称为OPGW光缆。将250μm光纤穿入高模量材料制成的松套管内,松套管内填充防水化合物。松套管外纵向包覆一层双面涂层钢带(PSP),钢带与松套管之间加有阻水材料,保证光缆的紧密性和纵向阻水性。两根平行钢丝置于两侧,挤入聚乙烯护套,形成电缆。 特征 (1)110kV以上的高压线路,跨越较大(一般在250M以上)。 (2)维护方便,容易解决线路跨越问题,其机械特性能满足大跨越线路的需要。 (3)OPGW外层为金属铠装,对高压腐蚀和劣化无影响。 (4)OPGW在施工过程中必须断电,造成重大损失。因此,110kV以上高压线路施工,应采用OPGW。 (5)在OPGW的性能指标中,短路电流越大,越需要采用良导体做铠装,这相应地降低了抗拉强度。而当抗拉强度一定时,要提高短路电流容量,唯一的办法就是增加金属截面积,这就导致光缆直径和重量的增加。这对输电杆塔的强度提出了安全问题。 结构 OPGW光缆主要用于500KV、220KV、110KV电压等级线路上,新建线路上因停电、安全等因素常采用OPGW光缆。 主要有铝管式、铝框式、(不锈钢)管式三大类。 订货须知 a.需要提供使用场景,比如山林、过江、桥梁、水下、管道、风电场等 b.需提供芯数、型号、跨度、拉力、截面、材料要求等设计要求 c.请提供所需光缆类型,包括中心管结构和层绞结构 d.如需定制,需提供其他已知的详细技术参数或设计图纸 OPGW光缆型号及填充示意图
