| 1、应用： | application: |
| 以不活泼的氮气充入绝缘介质层构成细密均匀的微孔结构，各微孔间互不连通，类似一个个密封仓。它的优点是高发泡度，又不含极性分子的发泡剂残留物，因此传输性能优良，适合于主干电缆、分支电缆、用户电缆及网络连接。由于它不透水不透气，性能特别稳定、使用寿命长。 | asthe inactive nitrogen in insulation dielectric layer, it will forman even and compact micro-hole structure with no linkage betweeneach micro-hole which like the sealed room. its advantage lies inits high degree of foaming while without vesicant leftover ofpolarity molecule, so it has a fine transmission performance and isfit for being used in backbone cable, sub-cable, owner’s cable andinternet connection. it has an extra stable performance and longservice life because of its water-proof and airproofproperties. |
