Nā ʻano Sheath maʻamau no nā kaula Optical a me kā lākou hana

I mea e pale ʻia ai ke kumu o ke kaula optical mai ka mechanical, thermal, kemikala, a me nā pōʻino e pili ana i ka makū, pono ia e hoʻolako ʻia me kahi ʻūpā a i ʻole nā ​​​​papa waho ʻē aʻe. Hoʻolōʻihi kēia mau hana i ke ola lawelawe o nā fiber optical.

ʻO nā ʻūpā i hoʻohana pinepine ʻia i loko o nā kaula optical e komo pū me nā ʻūpā A (nā ʻūpā i hoʻopaʻa ʻia me ka alumini-polyethylene), nā ʻūpā S (nā ʻūpā i hoʻopaʻa ʻia me ke kila-polyethylene), a me nā ʻūpā polyethylene. No nā kaula optical wai hohonu, hoʻohana pinepine ʻia nā ʻūpā i hoʻopaʻa ʻia me ka metala.

Hana ʻia nā ʻūpā polyethylene mai ka linear low-density, medium-density, a i ʻolemea polyethylene ʻeleʻele kiʻekiʻe, e kūlike ana me ke kūlana GB/T15065. Pono ka ʻili o ka ʻūpā polyethylene ʻeleʻele e laumania a like, ʻaʻohe pehu i ʻike ʻia, nā lua pine, a i ʻole nā ​​māwae. Ke hoʻohana ʻia ma ke ʻano he ʻūpā waho, pono ka mānoanoa maʻamau he 2.0 mm, me ka mānoanoa liʻiliʻi he 1.6 mm, a ʻo ka mānoanoa awelika ma kekahi ʻāpana kea ʻaʻole e emi ma lalo o 1.8 mm. Pono nā waiwai mechanical a me ke kino o ka ʻūpā e hoʻokō i nā koi i kuhikuhi ʻia ma YD/T907-1997, Papa 4.

ʻO ka ʻūpā A he papa pale makū i hana ʻia me nā mea i wahī ʻia a uhi ʻia me ka lōʻihi.lipine alumini i uhi ʻia me ka palakiko, i hui pū ʻia me kahi ʻūpā polyethylene ʻeleʻele i hoʻopuka ʻia. Hoʻopili ka ʻūpā polyethylene me ka lipine composite a me nā ʻaoʻao overlap o ka lipine, hiki ke hoʻoikaika hou ʻia me ka pipili inā pono. ʻAʻole pono ka laulā overlap o ka lipine composite ma lalo o 6 mm, a i ʻole no nā ʻōpū kaula me nā diameters ma lalo o 9.5 mm, ʻaʻole pono e emi ma mua o 20% o ke anapuni o ke kumu. ʻO ka mānoanoa maʻamau o ka ʻūpā polyethylene he 1.8 mm, me ka mānoanoa liʻiliʻi o 1.5 mm, a ʻo ka mānoanoa awelika ʻaʻole emi ma lalo o 1.6 mm. No nā papa waho Type 53, ʻo ka mānoanoa maʻamau he 1.0 mm, ʻo ka mānoanoa liʻiliʻi he 0.8 mm, a ʻo ka mānoanoa awelika he 0.9 mm. Pono ka lipine composite alumini-plastic e hoʻokō i ke kūlana YD/T723.2, me ka lipine alumini he mānoanoa maʻamau o 0.20 mm a i ʻole 0.15 mm (ka palena iki o 0.14 mm) a me ka mānoanoa kiʻiʻoniʻoni composite o 0.05 mm.

ʻAe ʻia kekahi mau hui lipine composite i ka wā o ka hana ʻana i ke kaula, inā ʻaʻole emi ka mamao o nā hui ma mua o 350 m. Pono kēia mau hui e hōʻoia i ka hoʻomau uila a hoʻihoʻi i ka papa plastik composite. ʻAʻole pono ka ikaika ma ka hui e emi ma mua o 80% o ka ikaika o ka lipine mua.

Hoʻohana ka ʻūpā S i kahi papa pale makū i hana ʻia me ka corrugated i wahī ʻia a uhi ʻia.lipine kila i uhi ʻia me ka palakiko, i hui pū ʻia me kahi ʻūpā polyethylene ʻeleʻele i hoʻokuʻu ʻia. Hoʻopili ka ʻūpā polyethylene me ka lipine composite a me nā ʻaoʻao overlapping o ka lipine, hiki ke hoʻoikaika ʻia me ka pipili inā pono. Pono ka lipine composite corrugated e hana i kahi ʻano apo ma hope o ka ʻōwili ʻana. ʻAʻole pono ka laulā overlapping ma lalo o 6 mm, a no nā ʻōpū kaula me nā diameters ma lalo o 9.5 mm, ʻaʻole pono e emi ma lalo o 20% o ke anapuni o ke kumu. ʻO ka mānoanoa maʻamau o ka ʻūpā polyethylene he 1.8 mm, me ka mānoanoa liʻiliʻi o 1.5 mm, a me ka mānoanoa awelika ʻaʻole emi ma lalo o 1.6 mm. Pono ka lipine composite kila-plastic e hoʻokō i ke kūlana YD/T723.3, me ka lipine kila he mānoanoa maʻamau o 0.15 mm (ka palena iki o 0.13 mm) a me ka mānoanoa kiʻiʻoniʻoni composite o 0.05 mm.

ʻAe ʻia nā hui lipine composite i ka wā o ka hana ʻana i ke kaula, me ka liʻiliʻi o ka mamao o nā hui he 350 m. Pono e hoʻopili ʻia ke lipine kila ma ke kua, e hōʻoiaʻiʻo ana i ka hoʻomau uila a hoʻihoʻi i ka papa composite. ʻAʻole pono ka ikaika ma ka hui ʻana ma lalo o 80% o ka ikaika o ka lipine composite mua.

Pono ka lipine alumini, ka lipine kila, a me nā papa pale hao i hoʻohana ʻia no nā pale makū e mālama i ka hoʻomau uila ma ka lōʻihi o ke kaula. No nā ʻūpā i hoʻopaʻa ʻia (me nā papa waho Type 53), ʻo ka ikaika ʻili ma waena o ka lipine alumini a kila paha a me ka ʻūpā polyethylene, a me ka ikaika ʻili ma waena o nā kihi e uhi ana o ka lipine alumini a kila paha, ʻaʻole ia e emi ma mua o 1.4 N/mm. Eia nō naʻe, i ka wā e hoʻopili ʻia ai kahi mea pale wai a i ʻole ka uhi ma lalo o ka lipine alumini a kila paha, ʻaʻole pono ka ikaika ʻili ma nā kihi e uhi ana.

Hoʻomaopopo kēia ʻano palekana piha i ka lōʻihi a me ka hilinaʻi o nā kaula optical ma nā ʻano like ʻole, e hoʻokō pono ana i nā pono o nā ʻōnaehana kamaʻilio hou.
