一种低烟无卤1e型核电站用k3级计算机电缆

Low-smoke halogen-free 1E-type nuclear-power-station-used K3-grade computer cable

Abstract

本实用新型公开了一种低烟无卤1E型核电站用K3级计算机电缆,包括多个芯线;每个芯线包括经对绞的两个导体、在所述两个导体对绞中增加的两个填充芯以及在所有导体和填充芯外部包覆的单面铝塑复合层,每个导体包括位于中部的导线以及包覆在导线外部的聚酯薄膜层和绝缘层,绝缘层采用核电用抗辐照低烟无卤硅橡胶制成;多个芯线构成缆芯,在所述缆芯外部包覆绕包层,在绕包层外部包覆镀银铜丝编织层,在镀银铜丝编织层外部包覆护套层,所述护套层采用核电用抗辐照低烟无卤硅橡胶制成。本实用新型提出的低烟无卤1E型核电站用K3级计算机电缆,其抗辐照、屏蔽性能好、抗拉伸性和柔韧性好,能够长期在核电站环境下安全使用。
The utility model discloses a low-smoke halogen-free 1E-type nuclear-power-station-used K3-grade computer cable which includes a plurality of core wires. Each core wire includes two conductors which undergo pair twist, two filling cores added in the pair twist of the two conductors and a single-face aluminum-plastic composite layer which wraps externally all corresponding conductors and filling cores. Each conductor includes a wire located at the middle part, and a polyester film layer and an insulating layer, which externally wrap the wire. Each insulating layer is made of a radiation-resistance low-smoke halogen-free silicone rubber used for nuclear power. The plurality of core wires form a cable core. The cable core is externally wrapped with a lapping layer. The lapping layer is externally wrapped with a silver-plated copper-wire woven layer. The silver-plated copper-wire woven layer is externally wrapped with a sheath layer. The sheath layer is made of the radiation-resistance low-smoke halogen-free silicone rubber used for the nuclear power. The low-smoke halogen-free 1E-type nuclear-power-station-used K3-grade computer cable is great in radiation resistance and shielding performance, great in stretch resistance and flexibility and capable of being used safely under a nuclear-power-station environment for a long term.
