ʻO ke koho ʻana i ka mea uhi waho no kahi uwea fiber optic e noʻonoʻo ana i kekahi mau mea e pili ana i ka noi ʻana o ke kelepona, kaiapuni, a me nā koi hana.Eia kekahi mau manaʻo koʻikoʻi e kōkua iā ʻoe e koho i ka mea kūpono o ka puʻu waho no nā uwea fiber optic:
Nā Kūlana Kaiapuni: E loiloi i nā kūlana kahi e hoʻokomo ʻia ai ke kaula.E noʻonoʻo i nā mea e like me ke ana wela, ka ʻike ʻana i ka makū, nā kemika, nā kukui UV, ka ʻāʻī, a me nā mea pōʻino ʻē aʻe.
Mechanical Protection: E hoʻoholo i ke kiʻekiʻe o ka pale mechanical e pono ai.Inā hoʻokomo ʻia ke kaula i loko o nā wahi ʻino a i ʻole nā wahi e pōʻino kino, pono ʻoe i kahi mea hoʻoheheʻe e hāʻawi i ke kūpaʻa kiʻekiʻe i ka abrasion a me ka hopena.
ʻO ke ahi a me ka lapalapa ahi:ʻO kekahi mau noi, ʻoi aku ka poʻe i loko o ka ʻenehana a i ʻole ka pilikia nui, pono paha i nā uwea me ka pale ahi a i ʻole ka pale ahi i waho e hoʻokō i nā lula palekana.
ʻO ka maʻalahi a me ka radius Bend:No nā mea hoʻonoho kahi e pono ai ke kulou a hoʻopololei paha, ke koho ʻana i kahi mea hoʻoheheʻe e hāʻawi i ka maʻalahi me ka ʻole o ka hoʻokō ʻana o ke kaula he mea koʻikoʻi.
Palekana Kemika:E noʻonoʻo inā e ʻike ʻia ke kaula i nā kemika a i ʻole nā mea ʻino.E koho i kahi mea e hiki ai ke pale aku i kēia mau mea no ka mālama pono ʻana i ke kaula.
Palena UV:Inā ʻike ʻia ke kaula i ka lā a i ʻole nā kūlana o waho, e pale nā mea pale UV i ka hōʻino ʻana i ka wā ma muli o ka lōʻihi o ka hoʻolaha ʻana i nā kukuna ultraviolet.
Kumukuai noonoo:E kaulike i nā koi o ka hana me nā koina koina.Hiki ke hāʻawi aku kekahi mau mea kūikawā i nā waiwai ʻoi aku ka maikaʻi akā hiki mai ke kumu kūʻai kiʻekiʻe.
Hoʻokō a me nā kūlana:E hōʻoia i ka hoʻokō ʻana o nā mea i koho ʻia me nā kūlana ʻoihana a me nā lula no ka noi i manaʻo ʻia.
ʻO nā mea maʻamau i hoʻohana ʻia no nā sheaths o waho i nā uwea fiber optic: Pehea e koho ai i ka fiber optic cable outer sheath material?
1 PVC
2 PE
3 LSZH
4 AT
5 Anti-Rodent
6 Anai-Ala
PVC
ʻO PVC ka mea i hoʻohana nui ʻia i ka fiber optic cable outer sheath material.Loaʻa iā ia nā hana maikaʻi, ke kūpaʻa kemika maikaʻi a me ka pale ʻana i ka wā, ke kumukūʻai haʻahaʻa, haʻahaʻa flammability, a hiki ke hoʻokō i nā koi o nā manawa maʻamau.Eia nō naʻe, ʻo ka PVC sheathed optical cable e hoʻopuka i ka uahi nui ke puhi ʻia, ʻaʻole ia e pili i ka kaiapuni.
PE
ʻAʻohe mea ʻala o ka polyethylene sheath, non-toxic, like me ka wax.Loaʻa iā ia ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi loa (hiki i ka wela haʻahaʻa ke hiki i -100 ~ -70 ° C), kūpaʻa kemika maikaʻi, a hiki ke kū i ka hapa nui o nā waikawa a me nā alkalis (ʻaʻole kū i ka oxidation) Nature o ka waikawa).ʻAʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau i ka lumi wela, he haʻahaʻa haʻahaʻa wai a me ka insulation uila maikaʻi loa.
Ma muli o ka haʻahaʻa haʻahaʻa, ka maikaʻi o ka ea permeability, ka insulation maikaʻi loa a me ka pale ʻana o UV o ka PE fiber cable i waho o ka sheath, hoʻohana pinepine ʻia i nā kaiapuni waho.Ma muli o ka nui o ka PE fiber cable outer sheath, aia kekahi MDPE (waena waena) a me HDPE (kiʻekiʻe kiʻekiʻe).
LSZH
ʻO LSZH (low smoke zero halogen) he mea hoʻopaʻa i ka lapalapa ahi i hoʻopiha ʻia me nā mea hoʻopiha inorganic (aluminum hydroxide, magnesium hydroxide).ʻAʻole hiki i ka LSZH sheathed fiber optic cable ke hoʻoheheʻe wale i ka neʻe ʻana o nā mea puhi ahi, akā e komo pū i ka wela i hana ʻia e ka puhi ʻana, a ma ka manawa like e hoʻoulu ai i kahi pale oxygen non-combustible.
LSZH fiber optic uweaLoaʻa i ka hana pale ahi maikaʻi loa, ka uahi liʻiliʻi i ka wā o ka puhi ʻana, ʻaʻohe uahi ʻeleʻele ʻawaʻawa, ʻaʻohe kinoea e pakele ai, ikaika tensile maikaʻi, kūpaʻa aila a palupalu, kūpaʻa kiʻekiʻe kiʻekiʻe, kūpono no ke kaiapuni me nā koi retardant ahi a kū i nā koi uila.ʻO ka hemahema ʻo ia ka maʻalahi o ka LSZH sheath e haki.
AT
Hiki ke kiʻi ʻia ka puʻu o waho o ke kaula optical o ka mea AT ma ka hoʻohui ʻana i nā mea hoʻohui i ka PE.ʻO kēia ʻano puʻupuʻu he hana anti-tracking maikaʻi, no laila ke hoʻohana pinepine ʻia ka uwea optical i loko o ke kaiapuni uila uila kiʻekiʻe e pono ai ka sheath o ka mea AT.
Anti-Rodent
ʻO kekahi mea maʻamauuwea opticalʻO ka sheathing material kahi mea anti-rodent, i hoʻohana ʻia no nā kaula optical i waiho ʻia i loko o nā tunnels a me nā papahana lalo.Hoʻokaʻawale ʻia ka mīkini i ka pale kemika a me ka pale kino.Ma waena o lākou, ʻoi aku ka maikaʻi o ka pale kino, a hiki ke hoʻohana ʻia ke kaula aramid a me nā mea kila kila e pale ai i ka ʻai ʻana o nā rodent.
Anai-Ala
Ke hoʻohana ʻia kahi uwea fiber optic i nā mines a i ʻole nā mea palekana ʻē aʻe ma mua, pono nā ʻano anti-flame maikaʻi o ke kaula fiber optic.ʻO ke kaula ʻōpiʻomaʻo pale ahi he mea pale polyethylene sheath mea hoʻopaʻa ahi ma kahi o nā mea hoʻopaʻapaʻa polyethylene sheath maʻamau, i loaʻa i ke kaula ʻike nā waiwai pale ahi.
