Kuti tambo ye optical cable ive nechokwadi chekuti yakachengetedzwa kubva mukukuvadzwa kwemakanika, kupisa, makemikari, uye hunyoro, inofanira kunge iine sheath kana mamwe ma layers ekunze. Matanho aya anowedzera hupenyu hwekushanda kwetambo dze optical.
Masheath anoshandiswa zvakanyanya mutambo dzeoptical anosanganisira maA-sheaths (aruminiyamu-polyethylene bonded sheaths), maS-sheaths (simbi-polyethylene bonded sheaths), uye mapolyethylene sheaths. Kune tambo dzeoptical dzakadzika, masheaths esimbi akavharwa anowanzo shandiswa.
Masheya ePolyethylene anogadzirwa ne-linear low-density, medium-density, kanazvinhu zve polyethylene nhema zvakanyanya, zvichienderana nechiyero cheGB/T15065. Pamusoro peganda repolyethylene dema rinofanira kunge rakatsetseka uye rakafanana, risina mabubbles anooneka, maburi emapini, kana mitswe. Kana ikashandiswa seganda rekunze, ukobvu hwayo hunofanira kunge huri 2.0 mm, nehukobvu hushoma hwe1.6 mm, uye hukobvu hwepakati pechikamu chipi nechipi hahufanirwe kunge huri pasi pe1.8 mm. Hunhu hwemakanika uye hwepanyama hweganda hunofanira kusangana nezvinodiwa zvakataurwa muYD/T907-1997, Tafura 4.
Mupendero weA une jira rekudzivirira hunyoro rakagadzirwa nekuputirwa kwenguva refu uye kupindiranatepi yepurasitiki yakafukidzwa nearuminiyamu, yakabatanidzwa ne sheath ye polyethylene nhema yakaburitswa. Sheath ye polyethylene inobatanidzwa ne tape ye composite uye mipendero ye tepi inopindirana, iyo inogona kusimbiswa zvakare ne namati kana zvichidikanwa. Upamhi hwe tape ye composite haufanirwe kunge uri pasi pe 6 mm, kana kuti kune tambo dzine dhayamita dziri pasi pe 9.5 mm, haifanirwe kunge iri pasi pe 20% ye central circumference ye core. Ukobvu hwe nominal hwe polyethylene sheath i 1.8 mm, nehukobvu hushoma hwe 1.5 mm, uye hukobvu hushoma hwe 1.6 mm. Kune Type 53 outer layers, hukobvu hushoma hwe 1.0 mm, hukobvu hushoma hwe 0.8 mm, uye hukobvu hushoma hwe 0.9 mm. Aluminum-plastic composite tape inofanira kusangana ne YD/T723.2 standard, ne aluminium tape iine hukobvu hushoma hwe 0.20 mm kana 0.15 mm (hushoma hwe 0.14 mm) uye hukobvu hwe firimu ye composite hwe 0.05 mm.
Majoini mashoma ematepi anobvumirwa panguva yekugadzira tambo, chero bedzi nzvimbo yejoini iri pasi pe350 m. Majoini aya anofanira kuona kuti magetsi anoramba aripo uye kudzoreredza purasitiki yakabatana. Simba riri pajoini harifanirwe kunge riri pasi pe80% yesimba retepi yekutanga.
S-sheath inoshandisa jira rekudzivirira hunyoro rakagadzirwa ne corrugated yakaputirwa kwenguva refu uye yakabatana.tepi yesimbi yakaputirwa nepurasitiki, yakabatanidzwa ne sheath ye polyethylene nhema yakaburitswa. Sheath ye polyethylene inobatanidzwa ne tape ye composite uye mipendero ye tepi inopindirana, iyo inogona kusimbiswa ne namira kana zvichidikanwa. Tepi ye corrugated composite inofanira kuita chimiro chakaita serin'i mushure mekuputira. Upamhi hwe overlap haufanirwe kunge huri pasi pe 6 mm, kana kune tambo dze cable dzine dhayamita iri pasi pe 9.5 mm, haifanirwe kunge iri pasi pe 20% ye central circumference. Ukobvu hwe nominal hwe polyethylene sheath i 1.8 mm, nehukobvu hushoma hwe 1.5 mm, uye hukobvu hwepakati husingasviki 1.6 mm. Tepi ye steel-plastic composite inofanira kusangana ne YD/T723.3 standard, ne steel tape ine nominal ukobvu hwe 0.15 mm (hushoma hwe 0.13 mm) uye hukobvu hwe composite film hwe 0.05 mm.
Majoini ematepi akasanganiswa anotenderwa panguva yekugadzira tambo, nepakati pemajoini 350 m. Tepi yesimbi inofanira kunge yakabatana nebutt, zvichiita kuti magetsi arambe achienderera mberi uye kudzoreredza jira rakasanganiswa. Simba riri pajoini harifanirwe kunge riri pasi pe80% yesimba retepi yekutanga yakasanganiswa.
Tepi yearuminiyamu, tepi yesimbi, uye zvidimbu zvesimbi zvinoshandiswa pakudzivirira hunyoro zvinofanirwa kuchengetedza kuenderera mberi kwemagetsi pamwe chete nekureba kwetambo. Kune zvidimbu zvakasungwa (kusanganisira zvidimbu zvekunze zveType 53), simba rekukwesha pakati petepi yearuminiyamu kana yesimbi nechikamu chepolyethylene, pamwe nesimba rekukwesha pakati pemipendero inokwesha yetepi yearuminiyamu kana yesimbi, hazvifanirwe kunge zviri pasi pe1.4 N/mm. Zvisinei, kana chinhu chinovhara mvura kana chifukidziro chikaiswa pasi petepi yearuminiyamu kana yesimbi, simba rekukwesha pamipendero inokweshana haridiwi.
Chimiro ichi chakazara chekudzivirira chinovimbisa kugara kwenguva refu uye kuvimbika kwetambo dze optical munzvimbo dzakasiyana-siyana, zvichizadzisa zvinodiwa nehurongwa hwemazuva ano hwekutaurirana.
