Nhasi, regai nditsanangure marongerwo akadzama etambo dzemarine Ethernet. Zvichitaurwa zviri nyore, tambo dzeEthernet dzakajairika dzine kondakita, insulation layer, shielding layer, uye outer sheath, nepo tambo dzearmored dzichiwedzera inner sheath nearmor layer pakati pe shielding neouter sheath. Zviri pachena kuti tambo dzearmored hadzingope dziviriro yemuchina chete asiwo imwe inodzivirira inner sheath. Iye zvino, ngationgororei chikamu chimwe nechimwe zvakadzama.
1. Mutyairi: Chinhu Chinokosha Pakutumira Zviratidzo
Madhairekita eEthernet anouya nezvinhu zvakasiyana-siyana zvinosanganisira mhangura yakachekwa, mhangura isina chinhu, waya yearuminiyamu, aruminiyamu yakachekwa, uye simbi yakachekwa nemhangura. Sekureva kweIEC 61156-5:2020, tambo dzemarine Ethernet dzinofanira kushandisa madhairekita emhangura akasimba ane dhayamita iri pakati pe0.4mm ne0.65mm. Sezvo kudiwa kwekumhanya kwakanyanya kwekutumira uye kugadzikana kuri kuwedzera, madhairekita asina kunaka akadai searuminiyamu nearuminiyamu yakachekwa nemhangura ari kudzikiswa, nemhangura yakachekwa nemhangura isina chinhu yava kutonga pamusika.
Kana tichienzanisa nemhangura isina chinhu, mhangura yakakangwa mugaba inopa kugadzikana kwakanyanya kwemakemikari, inodzivirira oxidation, ngura yemakemikari, uye hunyoro kuti irambe yakavimbika.
Maconductor anouya muzvikamu zviviri: yakasimba neyakavharirwa. Maconductor akasimba anoshandisa waya imwe chete yemhangura, nepo maconductor akavharirwa aine waya dzakawanda dzemhangura dzakatetepa dzakakomberedzwa pamwe chete. Musiyano mukuru uri mukushanda kwekutumira - sezvo nzvimbo dzakakura dzinoderedza kurasikirwa kwekuisa, maconductor akavharirwa anoratidza kuderera kwe20%-50% kupfuura dzakasimba. Mipata iri pakati petambo inowedzerawo kuramba kweDC.
Mawaya mazhinji eEthernet anoshandisa madhairekita e23AWG (0.57mm) kana 24AWG (0.51mm). Kunyange hazvo CAT5E ichiwanzoshandisa 24AWG, mapoka akakwirira akadai seCAT6/6A/7/7A anowanzoda 23AWG kuti ashande zviri nani. Zvisinei, mitemo yeIEC haimanikidze magauji ewaya chaiwo - waya dze24AWG dzakagadzirwa zvakanaka dzinogona kuzadzisa zvinodiwa neCAT6+.
2. Chidziviriro Chekudzivirira: Kudzivirira Kuvimbika Kwechiratidzo
Chidziviriro ichi chinodzivirira kubuda kwechiratidzo panguva yekutumira. Zvichitevera IEC 60092-360 uye GB/T 50311-2016, tambo dzemugungwa dzinowanzo shandisapolyethylene yakakura (HDPE)kana kuti furopolyethylene (PE Foam). HDPE inopa simba rakanaka kwazvo pakupisa, simba remakanika, uye simba rekudzivirira kukanganiswa kwezvakatipoteredza, zvichiita kuti ishande zvakanyanya. PE ine furo inopa hunhu huri nani hwe dielectric, zvichiita kuti ive yakakodzera tambo dzinomhanya zvikuru dzeCAT6A+.
3. Musiyano weChikamu: Kuderedza Kutaurirana kweChiratidzo
Chinopatsanura muchinjikwa (chinozivikanwawo sekuti cross filler) chakagadzirwa kuti chiparadzanise mapeya mana akamonyoroka kuita ma quadrants akasiyana, zvichideredza kutaura pakati pemapeya. Kazhinji chakagadzirwa nezvinhu zveHDPE zvine dhayamita yakajairika ye0.5mm, chikamu ichi chakakosha kune tambo dzeCategory 6 nedzepamusoro dzinotumira data pa1Gbps kana nekukurumidza, sezvo tambo idzi dzichiratidza kunzwa kwakanyanya kune ruzha rwechiratidzo uye dzinoda kuramba kwakawedzerwa kwekupindira. Nekuda kweizvozvo, tambo dzeCategory 6 nepamusoro dzisina kudzivirirwa kwefoil dzinoshandisa ma cross fillers kuti dziparadzanise mapeya mana akamonyoroka.
Kusiyana neizvi, tambo dzeCategory 5e nedzinoshandisa magadzirirwo efoil ane chidzitiro chepakati hadzisi kushandisa cross filler. Magadzirirwo etambo dzeCat5e dzakatwasuka anopa dziviriro yakakwana yekukanganiswa kwezvinodiwa zvadzo zvebandwidth, zvichibvisa kudiwa kwekuparadzanisa kwakawedzerwa. Saizvozvowo, tambo dzine chidzitiro chefoil dzinoshandisa kugona kwefoil yealuminium kudzivirira kukanganiswa kwemagetsi emagetsi ane frequency yakakwira, zvichiita kuti cross filler isakoshe.
Simba rekudhonza rinoita basa rakakosha mukudzivirira kurebeswa kwetambo izvo zvinogona kukanganisa mashandiro azvo. Vagadziri vetambo vanotungamira muindasitiri vanoshandisa fiberglass kana nylon senzira yekusimbisa kudhonza mukugadzirwa kwetambo dzavo. Zvinhu izvi zvinopa dziviriro yakakwana yemuchina ukuwo zvichichengetedza hunhu hwekutumira kwetambo.
4. Chidziviriro: Dziviriro yeMagineti
Zvidzitiro zvinoumba jira realuminium foil uye/kana mesh yakarukwa kuti ivhare EMI. Tambo dzine jira rimwe chete dzinoshandisa jira rimwe chete realuminium foil (≥0.012mm ukobvu ne ≥20% inopindirana) pamwe ne PET mylar layer kudzivirira kubuda kwemvura. Mhando dzine jira mbiri dzinouya mumhando mbiri: SF/UTP (foil yose + braid) uye S/FTP (foil imwe neimwe + braid yose). Kurukwa kwemhangura kwakaiswa mugaba (≥0.5mm wire diameter) kunopa kufukidza kunogadziriswa (kazhinji 45%, 65%, kana 80%). Sekureva kweIEC 60092-350, tambo dzegungwa dzine jira rimwe chete dzinoda waya yekudhonza mvura kuti dzigadzirwe pasi, nepo mhando dzine jira mbiri dzinoshandisa jira rekudhonza mvura kuti ribude mvura isina kusimba.
5. Chigadziko chezvombo: Dziviriro yeMichina
Chidzitiro ichi chinowedzera kusimba kwesimba rekupwanya/kupwanya uye chinovandudza kudzivirira kweEMI. Tambo dzemugungwa dzinonyanya kushandisa dzimbo dzakarukwa zvichienderana neISO 7959-2, newaya yesimbi yakarukwa (GSWB) inopa simba rakawanda uye kudzivirira kupisa pakushandisa kwakaoma, nepo waya yemhangura yakachekwa (TCWB) ichipa kusimba kuri nani panzvimbo dzakamanikana.
6. Mugoba weKunze: Chidziviriro cheZvakatipoteredza
Chidimbu chekunze chinofanira kunge chakatsetseka, chakabatana, uye chinobviswa pasina kukuvadza zvikamu zviri pasi. Mitemo yeDNV inoda kuti ukobvu (Dt) huve 0.04×Df (dhayamita yemukati) +0.5mm, ne 0.7mm shoma. Tambo dzegungwa dzinonyanya kushandisaLSZH (halogen isina utsi hwakanyanya)zvinhu (SHF1/SHF2/SHF2 MUD grades paIEC 60092-360) zvinoderedza utsi hune chepfu panguva yemoto.
Mhedziso
Tambo dzese dzegungwa dzeEthernet dzinoratidza hunyanzi hwakanyatsogadzirwa. KuOW CABLE, takazvipira kusimudzira tekinoroji yetambo - inzwa wakasununguka kukurukura nesu zvaunoda!
