ʻO ka mea maʻamau, aia ʻekolu ʻano o nā uwea non-metallic overhead optical, GYFTY, GYFTS, GYFTA ʻekolu ʻano o nā kaula optical, inā ʻaʻole metala ʻole me ka mea kaua, a laila ʻo ia ʻo GYFTY, layer twisted non-metallic non-metallic optical cable, kūpono no mana, ma ke ʻano he alakaʻi, ke alakaʻi i ke kaula optical. ʻO GYFTA kahi mea i hoʻoikaika ʻole ʻia me ka metala, ʻo ke kaula fiber optic pale alumini. ʻO GYFTS kahi kumu i hoʻoikaika ʻole ʻia me ke kila.
Hoʻohana ka GYFTY optical cable i kahi ʻano hoʻoheheʻe ʻia, a hoʻopaʻa ʻia ka fiber optical i loko o kahi paipu manuahi i hana ʻia me nā mea polyester modulus kiʻekiʻe, a hoʻopiha ʻia ka paipu me kahi pūhui wai. Hoʻopili ʻia ka paipu hoʻokuʻu (a me ke kaula hoʻopihapiha) a puni kahi mea hoʻoikaika kikowaena non-metallic (FRP) i loko o ke kumu uwea paʻa, a ua hoʻopiha ʻia nā āpau o ke kumu uwea me ka momona pale wai. Puʻu polyethylene i hoʻokuʻu ʻia ma waho o ke kumu uwea.
Hoʻohana ka GYFTA optical cable i kahi ʻano wili ʻia. Hoʻopili ʻia ka fiber optical i loko o kahi puʻupuʻu manuahi i hana ʻia me nā mea polyester modulus kiʻekiʻe, a hoʻopiha ʻia ka paipu me kahi pūhui wai. Hoʻopili ʻia ka paipu hoʻokuʻu (a me ke kaula hoʻopihapiha) a puni kahi mea hoʻoikaika kikowaena non-metallic (FRP) i loko o ke kumu uwea paʻa, a ua hoʻopiha ʻia nā āpau o ke kumu uwea me ka momona pale wai. Hoʻopili lōʻihi ʻia ka pale alumini o waho o ke kumu uwea, a laila hoʻopau ʻia ka polyethylene sheath. ʻO GYFTS ka hale like me GYFTA, kahi e pani ai i ka pale alumini me ka lipine kila pālua.
ʻAʻohe mea metala i loko o ke ʻano o GYFTY, kūpono ia no ka wahi uila, ka wahi uila kiʻekiʻe, a me nā wahi me ka pilikia electromagnetic koʻikoʻi. ʻO ka mea maʻamau, hiki ke hoʻohana ʻia nā kelepona optical GYFTA a me GYFTS no ka mana uila, ma nā wahi me nā koi haʻahaʻa haʻahaʻa. Non-metallic FRP central reinforcing core, maikaʻi tensile hana, anti-conductive optical cable Nā hiʻohiʻona huahana: non-metallic (FRP) hoʻoikaika, kūpono no ka uila, kahi kiʻekiʻe-voltage, pale uila; anti-stretching, wear-resistant, anti-flattening, anti- Shock, hiki ke hoʻopiʻi pinepine, wili, wili, kulou (kūlou ʻaʻole iʻoi aku ma mua o 90 °), pu, a me nā mea ʻē aʻe, me nā waiwai mechanical maikaʻi; ʻO ka pōʻai wela kūpaʻa, ka puʻu piha, ka kulu anti-seepage, ka pale ahi a me nā kaiapuni maikaʻi ʻē aʻe. Hoʻoponopono pololei ʻia ka lōʻihi o ka lōʻihi a me ke kaula stranding pitch e hōʻoia i ka hana tensile maikaʻi a me nā ʻano wela o ka fiber optic; ʻoi aku ka nui o ke ola ma mua o 30 mau makahiki. ʻO ke kaumaha māmā, ka lōʻihi o ke kaula liʻiliʻi, a me ka ukana liʻiliʻi ma nā hale kiaʻi.
