Cov Cables Tsheb Npav Marine Piav Qhia: Cov Qauv, Hom, Cov Kev Xav Tau, thiab Cov Khoom Siv

Qauv

Ib puag ncig hauv hiav txwv muaj ntau yam nyuaj thiab hloov pauv tas li. Thaum lub sijhawm caij nkoj, cov nkoj raug cuam tshuam los ntawm nthwv dej, xeb ntsev, hloov pauv kub, thiab cuam tshuam hluav taws xob. Cov xwm txheej hnyav no ua rau muaj kev xav tau ntau dua rau cov xov hlau hauv hiav txwv, thiab ob qho tib si cov qauv cable thiab cov ntaub ntawv cable txuas ntxiv mus txhim kho kom ua tau raws li cov kev xav tau nruj dua.

Tam sim no, cov qauv ib txwm muaj ntawm cov xov hlau caij nkoj feem ntau suav nrog:

Cov khoom siv hluav taws xob: Cov tooj liab uas muaj hlua khi / cov tooj liab uas muaj hlua khi. Piv nrog cov tooj liab liab, cov tooj liab uas muaj hlua khi muaj kev tiv thaiv xeb zoo dua.

Cov khoom siv rwb thaiv tsev: Ua los ntawm cov ua npuas ncauj polyethylene (Foam-PE). Nws txo qhov hnyav thaum muab kev rwb thaiv tsev thiab kev ua haujlwm hluav taws xob zoo dua.

Cov khoom siv tiv thaiv: Cov ntawv ci txhuas tiv thaiv + cov hlau tooj liab braided tiv thaiv. Hauv qee qhov kev siv, cov ntaub ntawv tiv thaiv kev ua tau zoo xws lidaim kab xev tooj liab mylarkuj tseem siv tau. Lub qauv tiv thaiv ob npaug ua kom muaj kev sib kis mus deb nrog kev tiv thaiv hluav taws xob muaj zog dua.

Cov khoom siv plhaub: Cov plhaub polyolefin uas tsis muaj pa luam yeeb tsawg (LSZH). Nws ua tau raws li cov qauv ib leeg-core uas tiv taus hluav taws (IEC 60332-1), cov uas tiv taus hluav taws sib xyaw ua ke (IEC 60332-3-22), thiab cov uas tsis muaj pa luam yeeb ntau, tsis muaj halogen (IEC 60754, IEC 61034), ua rau nws yog cov khoom siv plhaub tseem ceeb rau kev siv hauv dej hiav txwv.

Cov saum toj no yog cov qauv tseem ceeb ntawm cov xov hlau marine. Hauv cov chaw uas muaj cov kev xav tau siab dua, tej zaum yuav xav tau cov ntaub ntawv cable tshwj xeeb ntxiv. Piv txwv li, kom ua tau raws li cov kev xav tau tiv thaiv hluav taws (IEC 60331), cov kab xev mica xws lidaim kab xev mica phlogopiteyuav tsum tau siv rau saum txheej rwb thaiv tsev; rau kev tiv thaiv kho tshuab zoo dua, cov hlau galvanized daim kab xev armor thiab ntxiv cov txheej sheath yuav raug ntxiv.

Kev faib tawm

Txawm hais tias cov qauv ntawm cov xov hlau hauv tsheb npav feem ntau zoo sib xws, lawv cov qauv thiab daim ntawv thov sib txawv heev. Cov hom xov hlau hauv tsheb npav feem ntau suav nrog:

1. Profibus PA
2. Profibus DP
3. CANBUS
4. RS485
5. Profinet

Feem ntau, Profibus PA/DP siv rau kev ua haujlwm tsis siv neeg thiab kev sib txuas lus PLC; CANBUS siv rau kev tswj cav thiab lub tswb ceeb toom; RS485 siv rau kev sib txuas lus ntawm cov cuab yeej siv thiab I/O chaw taws teeb; Profinet siv rau cov kab ke tswj ceev ceev thiab cov tes hauj lwm navigation.

Cov Kev Cai

Cov xov hlau hauv hiav txwv yuav tsum ua raws li ntau tus qauv kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb hauv cov chaw nyob hauv hiav txwv.
Kev tiv thaiv ntsev tsuag: Cov huab cua hauv dej hiav txwv muaj cov ntsev ntau, uas ua rau cov cables xeb heev. Cov cables tsheb npav hauv dej hiav txwv yuav tsum muaj kev tiv thaiv zoo heev rau kev xeb ntsev tsuag, thiab cov ntaub ntawv cable yuav tsum tiv thaiv kev puas tsuaj mus sij hawm ntev.

Kev tiv thaiv kev cuam tshuam hluav taws xob: Cov nkoj muaj ntau yam khoom siv uas tsim kev cuam tshuam hluav taws xob muaj zog. Cov xov hlau hauv nkoj yuav tsum muaj kev tiv thaiv EMI / RFI zoo heev kom ntseeg tau tias muaj kev sib kis ruaj khov.

Kev tiv thaiv kev co: Cov nkoj muaj kev co tas li vim yog nthwv dej cuam tshuam. Cov xov hlau hauv nkoj yuav tsum tswj tau qhov kev tiv thaiv kev co zoo, kom ntseeg tau tias muaj kev ruaj khov ntawm cov qauv.

Kev tiv taus kub thiab qis: Cov xov hlau hauv nkoj yuav tsum ua haujlwm tau zoo hauv qab qhov kub thiab txias heev. Cov khoom siv ib txwm muaj qhia txog qhov kub thiab txias ua haujlwm ntawm -40 ° C txog + 70 ° C.

Kev tiv thaiv hluav taws: Thaum muaj hluav taws kub, cov xov hlau uas kub hnyiab tuaj yeem tsim cov pa luam yeeb hnyav thiab cov pa phem, ua rau cov neeg ua haujlwm muaj kev nyab xeeb. Cov ntaub thaiv kab hlau hauv nkoj yuav tsum siv cov ntaub ntawv LSZH thiab ua raws li IEC 60332-1 ib lub tub ntxhais tiv thaiv hluav taws, IEC 60332-3-22 bundled flame retardance, thiab IEC 60754-1/2 thiab IEC 61034-1/2 cov kev cai uas tsis muaj pa luam yeeb tsawg, tsis muaj halogen.

Raws li cov qauv kev lag luam dhau los ua qhov nruj dua, daim ntawv pov thawj ntawm lub koom haum faib tawm tau dhau los ua qhov qhia txog kev ua tau zoo tseem ceeb dua. Ntau qhov project marine xav tau cov cables kom tau txais daim ntawv pov thawj xws li DNV, ABS, lossis CCS.
