Sezvo nzanga yemazuva ano ichikura, ma network ave chikamu chakakosha chehupenyu hwezuva nezuva, uye kutumira masaini e network kunoenderana ne network cables (dzinowanzozivikanwa se Ethernet cables). Senzvimbo yemazuva ano yeindasitiri inofambiswa mugungwa, marine ne offshore engineering iri kuramba ichiwedzera otomatiki uye ine hungwaru. Nzvimbo yacho yakaoma, zvichiita kuti pave nezvinodiwa zvakawanda pakugadzirwa kwe Ethernet cables nezvinhu zvinoshandiswa pa cable. Nhasi, tichataura muchidimbu nezve structure features, nzira dzekuisa muzvikamu, uye key material configurations ye marine Ethernet cables.
1. Kupatsanurwa kweCable
(1). Zvinoenderana neTransmission Performance
Tambo dzeEthernet dzatinowanzo shandisa dzinowanzo gadzirwa ne copper conductor twisted pair structures, dzine single kana multi-stranded copper conductors, PE kana PO insulation materials, dzakamonyoroka dziri mbiri, uye peya ina dzakagadzirwa kuita cable yakazara. Zvichienderana nekushanda, mhando dzakasiyana dzetambo dzinogona kusarudzwa:
Chikamu 5E (CAT5E): Chidimbu chekunze chinowanzogadzirwa nePVC kana polyolefin isina utsi hwakanyanya, ine frequency yekutumira ye100MHz uye kumhanya kwakanyanya kwe1000Mbps. Inoshandiswa zvakanyanya munetwork dzemumba nedzemahofisi.
Chikamu 6 (CAT6): Inoshandisa maconductor emhangura emhando yepamusoro uyepolyethylene yakakura (HDPE)zvinhu zvinodzivirira, zvine muchina wekuparadzanisa mafambiro emagetsi, zvichiwedzera bandwidth kusvika ku250MHz kuti kufambisa kwemagetsi kugadzikane.
Chikamu 6A (CAT6A): Kuwanda kwemafambiro kunowedzera kusvika ku500MHz, mwero wekutumirwa kwemashoko unosvika 10Gbps, kazhinji inoshandisa tepi yearuminiyamu yeMylar sechishongo chekudzivirira, uye inosanganiswa nezvinhu zvehalogen-isina utsi hwakawanda kuti zvishandiswe munzvimbo dzedata.
Chikamu 7 / 7A (CAT7/CAT7A): Inoshandisa 0.57mm conductor yemhangura isina oxygen, peya imwe neimwe yakadzivirirwa netepi yearuminiyamu+ waya yemhangura yakarukwa mugaba, ichisimbisa kusimba kwechiratidzo uye ichitsigira 10Gbps yekutumira nekukurumidza.
Chikamu 8 (CAT8): Chimiro chacho ndecheSFTP chine jira rekudzivirira rakaita mativi maviri (tepi yearuminiyamu yeMylar yepeya yega yega + jira rakarukwa), uye jira racho rinowanzova nejira reXLPo rinodzivirira moto zvakanyanya, richitsigira kumhanya kusvika ku2000MHz uye 40Gbps, rakakodzera kubatanidza michina munzvimbo dzedata.
(2). Zvichienderana neChimiro cheShielding
Zvichienderana nekuti zvinhu zvekudzivirira zvinoshandiswa here muchimiro, tambo dzeEthernet dzinogona kukamurwa kuita:
UTP (Unshielded Twisted Pair): Inoshandisa chete PO kana HDPE insulation material isina imwe shield, inodhura zvishoma, yakakodzera nzvimbo dzisina electromagnetic interference yakawanda.
STP (Shielded Twisted Pair): Inoshandisa aluminium foil Mylar tape kana copper wire braid sechinhu chekudzivirira, ichisimudzira kuramba kupindira, uye yakakodzera nharaunda dzakaoma dzemagetsi.
Tambo dzeMarine Ethernet dzinowanzo sangana nekukanganiswa kwakasimba kwemagetsi, zvichida zvimiro zvekudzivirira zvakanyanya. Magadzirirwo akajairika anosanganisira:
F/UTP: Inoshandisa aluminium foil Mylar tepi sechikamu chekudzivirira, chakakodzera CAT5E neCAT6, chinowanzoshandiswa mumasystem ekudzora ari mubhodhi.
SF/UTP: Tepi yeAruminiyamu ine foil yeMylar + chifukidziro chemhangura chisina mhangura, chinowedzera kuramba kweEMI, chinowanzoshandiswa pakushandisa simba remugungwa uye kutumira masaini.
S/FTP: Peya imwe neimwe yakamonyoroka inoshandisa tepi yearuminiyamu yeMylar yekudzivirira imwe neimwe, ine jira rekunze remhangura rakarukwa kuti ridzivirire zvese, rakabatana nemidziyo yeXLPO sheath inodzivirira moto zvakanyanya. Ichi chimiro chinowanzo shandiswa paCAT6A netambo dziri pamusoro.
2. Kusiyana muMarine Ethernet Cables
Zvichienzaniswa netambo dzeEthernet dzepasi, tambo dzeEthernet dzemugungwa dzine musiyano wakajeka mukusarudza zvinhu uye dhizaini yezvivakwa. Nekuda kwenzvimbo yakaoma yegungwa—mhute yakawanda yemunyu, hunyoro hwakawanda, kupindira kwakasimba kwemagetsi, mwaranzi yeUV yakanyanya, uye kutsva—zvinhu zvetambo zvinofanirwa kusangana nemazinga akakwirira ekuchengetedza, kugara kwenguva refu, uye kushanda zvakanaka kwemakanika.
(1). Zvinodiwa Zvakajairwa
Tambo dzeMarine Ethernet dzinowanzogadzirwa zvichienderana neIEC 61156-5 neIEC 61156-6. Kubatanidza tambo dzakatwasuka kunowanzo shandisa maconductor emhangura akasimba pamwe chete nezvinhu zvinodzivirira HDPE kuti zvive nyore kutumirwa kure uye kugadzikana; tambo dzepatch mumakamuri edata dzinoshandisa maconductor emhangura akavharirwa ane PO kana PE insulation yakapfava kuti zvive nyore kutenderera munzvimbo dzakamanikana.
(2) .Kudzivirirwa kweMurazvo uye Kuramba Moto
Kuti moto udzivise kupararira, tambo dzegungwa dzeEthernet dzinowanzo shandisa zvinhu zve polyolefin zvisina utsi hwakanyanya (zvakaita seLSZH, XLPO, nezvimwewo) pakuvhara, zvichisangana nezvinodiwa neIEC 60332 zvinodzivirira moto, IEC 60754 (isina halogen), uye IEC 61034 (zvisina utsi hwakanyanya). Kune masisitimu akakosha, mica tape nezvimwe zvinhu zvisingatsvi zvinowedzerwa kuti zvisangane nezvinodiwa neIEC 60331 zvinodzivirira moto, zvichiita kuti mabasa ekutaurirana arambe aripo panguva yemoto.
(3). Kuramba Oiri, Kuramba Kuora, uye Chimiro Chezvombo
Mumayuniti ari kure negungwa akadai seFPSOs nemadredgers, tambo dzeEthernet dzinowanzo sangana nemafuta uye zvinokanganisa ngura. Kuti sheath irambe yakasimba, zvinhu zve cross-linked polyolefin sheath (SHF2) kana SHF2 MUD zvinodzivirira mud zvinoshandiswa, zvinoenderana neNEK 606 chemical resistance standards. Kuti iwedzere simba remakanika, tambo dzinogona kubatanidzwa negalvanized steel wire braid (GSWB) kana tinned copper wire braid (TCWB), zvichipa simba rekudzvanya uye rekudhonza, pamwe chete ne electromagnetic shielding kuchengetedza signal integrity.
(4). Kuramba UV uye Kukwegura
Tambo dzeMarine Ethernet dzinowanzo shandiswa pachiedza chezuva, saka zvinhu zvesheath zvinofanira kunge zvine simba rekudzivirira UV. Kazhinji, polyolefin sheathing ine carbon black kana UV-resistant additives inoshandiswa uye inoedzwa pasi pemazinga eUL1581 kana ASTM G154-16 UV ekukura kuti ive nechokwadi chekugadzikana kwemuviri uye hupenyu hwebasa hwakareba munzvimbo dzine UV yakawanda.
Muchidimbu, dhizaini yega yega yetambo dzegungwa dzeEthernet dzakabatana zvakanyanya nekusarudzwa kwakanyatsoitwa kwetambo. Maconductor emhangura emhando yepamusoro, HDPE kana PO insulation materials, aluminum foil Mylar tape, copper wire braid, mica tape, XLPO sheath material, uye SHF2 sheath materials pamwe chete zvinoumba sisitimu yekutaurirana yetambo inokwanisa kutsungirira mamiriro egungwa akaomarara. Semupi wezvinhu zvetambo, tinonzwisisa kukosha kwemhando yezvinhu pakushanda kwetambo yese uye takazvipira kupa mhinduro dzakavimbika, dzakachengeteka, uye dzinoshanda zvakanaka kumaindasitiri egungwa nekunze kwegungwa.
