1. Simbi waya
Kuti ive nechokwadi chekuti tambo inogona kumira zvakakwana axial tension painoisa nekuisa, tambo inofanirwa kunge iine zvinhu zvinotakura mutoro, simbi, isiri-simbi, mukushandiswa kwesimbi yakasimba-simbi waya sechikamu chinosimbisa, kuitira kuti tambo ive yakanakisa kudivi kudzvinyirira kuramba, kukanganisa kupikisa, waya yesimbi inoshandiswawo kune tambo pakati pemukati sheath uye kunze kwechivharo chezvombo. Zvinoenderana nekabhoni yemukati inogona kukamurwa kuita yakakwira kabhoni simbi waya uye yakaderera kabhoni simbi waya.
(1) High carbon steel waya
Yakakwira kabhoni simbi waya simbi inofanira kusangana nehunyanzvi zvinodiwa zveGB699 yepamusoro-soro kabhoni simbi, zvirimo zvesarufa uye phosphorus zvinenge 0.03%, maererano nekusiyana kwepamusoro kurapwa kunogona kukamurwa kuita galvanized simbi waya uye phosphating simbi waya. Galvanized simbi waya inoda kuti zinc layer ive yunifomu, yakatsetseka, yakanyatsobatanidzwa, pamusoro petambo yesimbi inofanira kunge yakachena, isina mafuta, isina mvura, isina mavara; Iyo phosphating layer yephosphating wire inofanira kunge yakafanana uye yakajeka, uye pamusoro petambo inofanira kunge isina mafuta, mvura, ngura mavara uye mavanga. Nekuti huwandu hwekushanduka kwehydrogen idiki, kushandiswa kwephosphating simbi waya kwakajairika ikozvino.
(2) Low carbon steel waya
Yakadzika kabhoni simbi waya inowanzo shandiswa tambo yakashongedzwa, pamusoro petambo yesimbi inofanira kuputirwa neyunifomu uye inoenderera zinc layer, iyo zinc layer haifanirwe kuve nepakatsemuka, maki, mushure mekuedza kwemhepo, hapafanirwe kunge paine zvigunwe zvisina kuvharwa zvinogona kudzima kutsemuka, lamination uye kudonha.
2. Steel strand
Nekuvandudzwa kwetambo kusvika kunhamba huru yepakati, uremu hwetambo hunowedzera, uye kushushikana kunoda kutakura kunowedzerawo. Kuti uvandudze kukwanisa kwetambo ye optical kutakura mutoro uye kudzivisa axial stress inogona kugadzirwa mukuisa uye kushandiswa kwetambo ye optical, tambo yesimbi sechikamu chekusimbisa chetambo ye optical ndiyo inonyanya kukodzera, uye ine imwe shanduko. Simbi tambo inogadzirwa neakawanda tambo dzesimbi waya kumonyoroka, zvinoenderana nechikamu chechimiro chinogona kukamurwa kuita 1 × 3,1 × 7,1 × 19 marudzi matatu. Kusimbisa tambo kunowanzo shandisa 1 × 7 simbi tambo, simbi tambo zvinoenderana nezita rekuti simba resimbi rakakamurwa kuita: 175, 1270, 1370, 1470 uye 1570MPa mamakisi mashanu, iyo elastic modulus yesimbi tambo inofanirwa kunge yakakura kupfuura 180GPa. Simbi inoshandiswa kune tambo yesimbi inofanira kusangana nezvinodiwa zveGB699 "Technical Conditions for high-quality carbon steel structure", uye pamusoro pesimbi yesimbi yakashandiswa tambo yesimbi inofanira kuputirwa neyunifomu uye inoenderera mberi yezinc, uye hapafaniri kuva nemavara, kuputika uye nzvimbo dzisina zinc plating. Iyo dhayamita uye yekuisa kureba kwetambo yetambo yakaenzana, uye haifanirwe kuve yakasununguka mushure mekucheka, uye tambo yesimbi yetambo yetambo inofanirwa kubatanidzwa zvakanyanya, pasina crisscross, kuputsika uye kukotama.
3.FRP
FRP ndiyo chidimbu chetsamba yekutanga yeChirungu fiber reinforced plastic, inova isiri-simbi zvinhu zvine nzvimbo yakatsetseka uye yunifomu yekunze dhayamita inowanikwa nekuputira pamusoro peakawanda tambo dzegirazi faibha nechiedza chekuporesa resin, uye inoita basa rekusimbisa muoptical cable. Sezvo FRP isiri-metallic material, ine zvikomborero zvinotevera zvichienzaniswa nekusimbiswa kwesimbi: (1) Zvinhu zvisiri zvesimbi hazvinzwisisi kushamiswa kwemagetsi, uye optical cable yakakodzera nzvimbo dzemheni; (2) FRP haiburitse electrochemical reaction nehunyoro, haiburitse magasi anokuvadza uye zvimwe zvinhu, uye inokodzera kunaya, inopisa uye ine hunyoro mamiriro ekunze enzvimbo; (3) haiburitse induction ikozvino, inogona kumisikidzwa pamutsetse wepamusoro-voltage; (4) FRP ine hunhu hwehuremu huremu, hunogona kuderedza zvakanyanya huremu hwetambo. Nzvimbo yeFRP inofanira kuva yakatsetseka, iyo isiri-yakapoteredza inofanira kuva duku, dhayamita inofanira kuva yunifomu, uye hapafaniri kuva nekubatana muhurefu hwe disc.
4. Aramid
Aramid (polyp-benzoyl amide faibha) imhando yefaibha yakakosha ine simba guru uye yakakwira modulus. Yakagadzirwa kubva ku-p-aminobenzoic acid semonomeri, pamberi pekatalyst, muNMP-LiCl system, nemhinduro condensation polymerization, uyezve nekunyorova kuruka uye yakanyanya tension kupisa kurapwa. Parizvino, zvigadzirwa zvinoshandiswa zvinonyanya kugadzirwa modhi KEVLAR49 inogadzirwa neDuPont muUnited States uye mhando yechigadzirwa Twaron inogadzirwa naAkzonobel kuNetherlands. Nekuda kwekunaka kwayo kwepamusoro tembiricha kuramba uye kupisa kweiyo oxidation kuramba, inoshandiswa mukugadzira-yepakati-yekuzvitsigira (ADSS) optical cable reinforcement.
5. Girazi fiber shinda
Girazi faibha yarn chinhu chisiri-simbi chinowanzo shandiswa mukusimbisa tambo yekusimbisa, iyo inogadzirwa neakawanda tambo dzegirazi fiber. Iyo ine yakanakisa insulation uye corrosion kuramba, pamwe neakakwira tensile simba uye yakaderera ductility, zvichiita kuti ive yakanaka kune isiri-simbi yekusimbisa mune optical tambo. Kana ichienzaniswa nemidziyo yesimbi, girazi fiber yarn yakareruka uye haiburitse induced ikozvino, saka inonyanya kukodzera kune yakakwira-voltage mitsetse uye optical cable application munzvimbo dzakanyorova. Uye zvakare, iyo girazi fiber yarn inoratidza yakanaka kupfeka kuramba uye kuramba mamiriro ekunze mukushandiswa, kuve nechokwadi kugadzikana kwenguva refu kwetambo munzvimbo dzakasiyana siyana.
