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。 |
As
the inactive nitrogen in insulation dielectric layer, it will form
an even and compact micro-hole structure with no linkage between
each micro-hole which like the sealed room. Its advantage lies in
its high degree of foaming while without vesicant leftover of
polarity molecule, so it has a fine transmission performance and is
fit for being used in backbone cable, sub-cable, owner’s cable and
internet connection. It has an extra stable performance and long
service life because of its water-proof and airproof
properties. |
