2. Ọdịiche dị na eriri Ethernet Marine
Tụnyere eriri Ethernet nke dabere na ala, eriri Ethernet mmiri nwere ọdịiche doro anya na nhọrọ ihe yana nhazi nhazi. N'ihi ọnọdụ mmiri siri ike - alụlụ nnu dị elu, oke iru mmiri, nnyonye anya electromagnetic siri ike, radieshon UV siri ike, na ọkụ ọkụ - ihe ndị na-eji eriri USB ga-enwerịrị ụkpụrụ dị elu maka nchekwa, ịdịte aka na ịrụ ọrụ igwe.
(1).Standard chọrọ
A na-emepụta eriri mmiri Ethernet dịka IEC 61156-5 na IEC 61156-6 si dị. Igwe ọkụ kwụ n'ahịrị na-ejikarị ndị nduzi ọla kọpa siri ike jikọtara ya na ihe mkpuchi HDPE iji nweta ebe nnyefe dị mma na nkwụsi ike; Ụdọ mkpọchi n'ime ọnụ ụlọ data na-eji ndị nduzi ọla kọpa nwere eriri PO ma ọ bụ mkpuchi PE dị nro maka ịfegharị mfe n'ime oghere siri ike.

N'ime mpaghara ndị dị n'ụsọ mmiri dị ka FPSO na dredgers, eriri Ethernet na-ekpugherekarị mmanụ na mgbasa ozi na-emebi emebi. Iji meziwanye nkwụsi ike n'ọbọ, a na-eji ihe mkpuchi polyolefin jikọtara cross (SHF2) ma ọ bụ ihe SHF2 MUD na-eguzogide apịtị, na-akwado ụkpụrụ NEK 606 kemịkalụ. Iji nwetakwuo ike n'ibu, enwere ike iji eriri galvanized steel wire braid (GSWB) ma ọ bụ braid ọla kọpa tinned (TCWB), na-enye mkpakọ na ike ike, yana mkpuchi electromagnetic iji chebe iguzosi ike n'ezi ihe.
(4). Nguzogide UV na arụmọrụ ịka nká
A na-ekpughekarị eriri mmiri Ethernet na ìhè anyanwụ kpọmkwem, ya mere ihe n'ọbọ ga-enwerịrị ezigbo nguzogide UV. A na-eji polyolefin sheathing na carbon ojii ma ọ bụ ihe mgbakwunye na-eguzogide UV ma nwalee n'okpuru ụkpụrụ ịka nká UL1581 ma ọ bụ ASTM G154-16 iji hụ na nkwụsi ike anụ ahụ na ogologo ndụ ọrụ na gburugburu UV dị elu.
Na nchịkọta, ihe ọ bụla oyi akwa nke mmiri Ethernet cable imewe na-njikọ chiri anya na-akpachara anya nhọrọ nke USB ihe. Ndị na-eduzi ọla kọpa dị elu, HDPE ma ọ bụ PO mkpuchi ihe, aluminom foil Mylar teepu, braid waya braid, mica teepu, XLPO Sheath material, na SHF2 n'ọbọ ihe ọnụ na-etolite a nkwurịta okwu cable usoro ike iguzogide oké mmiri gburugburu. Dị ka onye na-eweta ihe eji eme ihe, anyị ghọtara mkpa ihe dị mma maka ịrụ ọrụ nke eriri dum ma na-agba mbọ ịnye ihe ngwọta a pụrụ ịdabere na ya, nchekwa na arụmọrụ dị elu maka ụlọ ọrụ mmiri na mmiri.
