Sezvo nzanga yemazuva ano ichikura, mambure aita chikamu chakakosha chehupenyu hwezuva nezuva, uye kufambisa kwemasaini etiweki kunovimba netambo dzetiweki (dzinowanzonzi tambo dzeEthernet). Senharembozha yemazuva ano maindasitiri mugungwa, marine and offshore engineering iri kuwedzera otomatiki uye nehungwaru. Mamiriro ezvinhu akanyanya kuoma, achiisa zvikumbiro zvakakwirira pane chimiro cheEthernet tambo uye tambo zvinhu zvinoshandiswa. Nhasi, tichasuma muchidimbu zvimiro, nzira dzekuisa, uye magadzirirwo akakosha emagetsi eEthernet tambo.
1.Cable Classification
(1).Maererano neTransmission Performance
Tambo dzeEthernet dzatinowanzo shandisa dzinowanzo gadzirwa nemhangura conductor dzakamonyoroka peya zvimiro, zvine makondakita emhangura ega kana akawanda ane tambo, PE kana PO insulation zvinhu, akamonereka ari maviri maviri, uyezve mapeya mana anoumbwa kuita tambo yakazara. Zvichienderana nekuita, mamakisi akasiyana etambo anogona kusarudzwa:
Category 5E (CAT5E): Sheath yekunze inowanzogadzirwa nePVC kana yakaderera-smoke halogen-isina polyolefin, ine transmission frequency ye100MHz uye yakakura kumhanya kwe1000Mbps. Inoshandiswa zvakanyanya mudzimba uye general office network.
Chikamu 6 (CAT6): Inoshandisa yepamusoro-giredhi copper conductors uyehigh-density polyethylene (HDPE)insulation zvinhu, ine dhizaini yekuparadzanisa, inowedzera bandwidth kusvika 250MHz kune yakagadzikana kutapurirana.
Chikamu 6A (CAT6A): Frequency inowedzera kusvika ku500MHz, chiyero chekufambisa chinosvika 10Gbps, chinowanzoshandisa aluminium foil Mylar tepi semaviri ekudzivirira zvinhu, uye inosanganiswa nepamusoro-soro-yakaderera-halogen-isina sheath zvinhu zvekushandisa munzvimbo dze data.
Chikamu 7 / 7A (CAT7/CAT7A): Inoshandisa 0.57mm oxygen-isina copper conductor, peya imwe neimwe yakadzivirirwaaluminium foil Mylar tepi+ yakazara tinned copper wire braid, inosimudzira chiratidzo chekuvimbika uye kutsigira 10Gbps yakakwirira-kumhanya kutapurirana.
Chikamu 8 (CAT8): Chimiro ndeye SFTP ine kaviri-layer shielding (aluminium foil Mylar tepi yepeyi yega yega + yakazara braid), uye sheath inowanzokwirisa-inodzoreredza moto-inodzoreredza XLPO sheath zvinhu, inotsigira kusvika 2000MHz uye 40Gbps kumhanya, yakakodzera kune yepakati-michina yekubatanidza data.
(2). Maererano neShielding Structure
Zvinoenderana nekuti zvinhu zvekudzivirira zvinoshandiswa muchimiro, tambo dzeEthernet dzinogona kukamurwa kuita:
UTP (Unshielded Twisted Pair): Inoshandisa chete PO kana HDPE insulation zvinhu isina imwe dziviriro, yakaderera mutengo, yakakodzera nharaunda ine kushoma kwemagetsi kukanganiswa.
STP (Shielded Twisted Pair): Inoshandisa aruminiyamu foil Mylar tepi kana mhangura waya yakarukwa sechinhu chinodzivirira, inosimudzira kupindira kuramba, yakakodzera kune yakaoma electromagnetic nharaunda.
Marine Ethernet tambo dzinowanzo tarisana nekukanganiswa kwakasimba kwemagetsi, inoda zvimiro zvekudzivirira. Zvirongwa zvakajairika zvinosanganisira:
F/UTP: Inoshandisa aluminium foil Mylar tepi seyakazara shielding layer, yakakodzera CAT5E uye CAT6, inowanzoshandiswa mumabhodhi ekudzora masisitimu.
SF/UTP: Aluminium foil Mylar tepi + isina mhangura yakarukwa shielding, inosimudzira yakazara EMI kuramba, inowanzoshandiswa kune simba remugungwa uye chiratidzo chekufambisa.
S/FTP: Peya imwe neimwe yakamonyoroka inoshandisa aruminiyamu foil Mylar tepi yekudzivirira yega, ine yekunze tambo yemhangura yakarukwa yekudzivirira yakazara, yakabatanidzwa nepamusoro murazvo-inodzoreredza XLPO sheath zvinhu. Ichi chimiro chakajairika cheCAT6A uye pamusoro petambo.
2. Kusiyana muMarine Ethernet Cables
Kuenzaniswa netambo-based Ethernet tambo, marine Ethernet tambo dzine misiyano yakajeka mukusarudzwa kwezvinhu uye dhizaini yekugadzira. Nekuda kwehutsinye hwenharaunda yemugungwa — mhute yakakwira yemunyu, hunyoro hwepamusoro, kukanganiswa kwemagetsi emagetsi, kusimba kwemwaranzi yeUV, uye kupisa — tambo dzetambo dzinofanirwa kusangana nemhando yepamusoro yekuchengetedza, kusimba, uye kuita kwemuchina.
(1).Standard Zvinodiwa
Marine Ethernet tambo dzinowanzo gadzirwa zvinoenderana neIEC 61156-5 uye IEC 61156-6. Horizontal cabling inowanzo shandisa maconductor akasimba emhangura akasanganiswa neHDPE insulation zvinhu kuti uwane kureba kwekufambisa uye kugadzikana; tambo dzechigamba mumakamuri edhata dzinoshandisa maconductor emhangura akasungwa ane yakapfava PO kana PE insulation kuitira nyore nzira munzvimbo dzakamanikana.
(2).Flame Retardancy uye Fire Resistance
Kudzivirira kupararira kwemoto, marine Ethernet tambo dzinowanzoshandisa yakaderera-utsi halogen-isina flame-retardant polyolefin zvinhu (senge LSZH, XLPO, zvichingodaro) kusheathing, kusangana IEC 60332 flame retardant, IEC 60754 (halogen-isina), uye IEC 61034 chiutsi chiyero. Kune masisitimu akakosha, mica tepi uye zvimwe zvinhu zvinodzivirira moto zvinowedzerwa kusangana neIEC 60331 moto-resistance standards, kuve nechokwadi chekuti mabasa ekutaurirana anochengetwa panguva yezviitiko zvemoto.
(3). Oiri Resistance, Corrosion Resistance, uye Armoring Structure
Mumayuniti ekumahombekombe akadai seFPSOs uye dredger, tambo dzeEthernet dzinowanzo kuoneswa kumafuta uye corrosive media. Kuvandudza sheath durability, cross-linked polyolefin sheath materials (SHF2) kana madhaka-resistant SHF2 MUD zvinhu zvinoshandiswa, zvinoenderana NEK 606 kemikari kuramba zviyero. Kuti uwedzere kusimbisa simba remuchina, tambo dzinogona kuve dzakashongedzwa nesimbi yakarukwa simbi (GSWB) kana tinned copper wire braid (TCWB), ichipa kumanikidza uye kusimba simba, pamwe nemagetsi ekudzivirira kuchengetedza chiratidzo.
(4). UV Resistance uye Kuchembera Kuita
Marine Ethernet tambo dzinowanzo kuoneswa zuva rakananga, saka sheath zvinhu zvinofanirwa kuve neakanakisa UV kuramba. Kazhinji, polyolefin sheathing ine kabhoni nhema kana UV-inodzivirira ekuwedzera inoshandiswa uye kuyedzwa pasi peUL1581 kana ASTM G154-16 UV yekuchembera zviyero kuti ive nechokwadi chekugadzikana kwemuviri uye yakawedzerwa hupenyu hwesevhisi munzvimbo dzakakwirira dzeUV.
Muchidimbu, dhizaini yega yega yemarine Ethernet tambo dhizaini inosungirirwa padhuze nekusarudzika kwetambo zvinhu. Yepamusoro-soro maconductor emhangura, HDPE kana PO insulation zvinhu, aluminium foil Mylar tepi, copper wire braid, mica tepi, XLPO sheath zvinhu, uye SHF2 sheath zvinhu pamwe chete zvinoumba tambo yekutaurirana inokwanisa kutsungirira nharaunda dzemugungwa. Semutengesi wetambo zvinhu, tinonzwisisa kukosha kwemhando yezvinhu pakuita kwetambo yese uye takazvipira kupa yakavimbika, yakachengeteka, uye yepamusoro-inoshanda zvigadziriso zvemaindasitiri emugungwa nekumahombekombe.
