Cov Khoom Xov Xwm

Cov xov hlau tsis ua raws li txoj cai ua rau poob teeb liab, cov khoom siv tsis ua haujlwm, thiab muaj kev phom sij rau kev nyab xeeb.

Cov ntaub ntawv kev lag luam qhia tau tias 80% ntawm cov kev teeb tsa tsis ua raws li txoj cai ntsib teeb meem hauv 18 lub hlis.

Kawm txog qhov tshwm sim tiag tiag ntawm kev hla dhau EN 50288-7, IEC 60332, lossis NEC cov cai - thiab vim li cas kev ua raws li txoj cai thiaj tiv thaiv koj lub Hoobkas.

Kev xaiv cov xov hlau ntau khub yuav tsum txiav txim siab seb muaj pes tsawg khub (1-100+), qhov loj ntawm tus xov hlau (18-24 AWG / 0.5-2.5mm²), hom tiv thaiv (ntawv ci/txoov ntxoo/sib xyaw), thiab cov ntaub tsho (PVC/LSZH/PUR).

Phau ntawv qhia no qhia txog kev ua raws li EN 50288-7 thiab cov kauj ruam xaiv cov teeb liab analog thiab digital.

EN 50288-7 yog tus qauv European rau cov cuab yeej siv thiab cov xov hlau tswj, qhia meej txog cov yam ntxwv hluav taws xob (impedance, capacitance, attenuation), cov khoom siv kho tshuab, nplaim taws retardancy, thiab qhov ntsuas kub.

Cov neeg yuav khoom yuav tsum xyuas kom meej tias lawv ua raws li cov qauv ntawm CE thiab cov lus qhia ntawm cov khoom.

Kawm cov kev cai tseem ceeb thiab daim ntawv teev npe xaiv.

Kev xaiv ntawm twisted pair (crosstalk reduction), coaxial (high-frequency), thiab BS5308 (roj & roj spec) nyob ntawm koj hom teeb liab, qhov deb, thiab ib puag ncig.

Cov khub sib txuas zoo heev rau 4-20mA thiab RS485. Coaxial rau zaus siab thiab video.

BS5308 ntxiv kev tiv thaiv tshuab thiab qib IS rau cov nroj tsuag petrochemical.

Kawm cov kev cai thiab cov kev zam.

Cov xov hlau uas muaj kev nyab xeeb yuav tsum yog xim xiav (RAL 5015) raws li IEC 60079-14 rau kev txheeb xyuas thaj chaw txaus ntshai.

Cov xim uas yuav tsum tau ua no tso cai rau cov kws hluav taws xob kom paub qhov txawv ntawm IS circuits thiab cov xov hluav taws xob uas tsis yog IS, tiv thaiv kev sib txuas tsis raug ntawm lub zog txaus ntshai.

Yog, raws li IEC 60079-14, cov xov hlau uas muaj kev nyab xeeb YUAV TSUM muaj lub plhaub sab nraud xiav (RAL 5015) rau kev txheeb xyuas thaj chaw txaus ntshai.

Cov xim code no yuav tsum tau ua kom pom tseeb tam sim ntawd ntawm IS circuits, tiv thaiv kev sib txuas tsis raug ntawm lub zog uas tsis yog IS.

Muaj kev zam tshwj xeeb rau cov xov hlau me me thiab cov kev teeb tsa uas twb muaj lawm.

Kawm cov kev cai thiab cov kev zam.

Ib txoj hlua SWA (Steel Wire Armour) uas muaj kev nyab xeeb ua ke nrog kev txwv zog (IS) nrog rau kev tiv thaiv tshuab (steel wire armor). Kev tiv thaiv kev sib tsoo txog li 4,000 N/10cm, kev tiv thaiv nas/kab, thiab lub zog tensile siab rau kev teeb tsa thaj chaw muaj kev phom sij. Lub plhaub LSZH xiav xiav ua kom muaj kev ua raws li IS thaum lub tsho tiv thaiv ua rau muaj kev ruaj khov.

Kawm cov kev cai thiab cov kev zam.

Ib txoj hlua ceeb toom hluav taws uas muaj kev nyab xeeb ua ke kev txwv hluav taws xob (tiv thaiv kev kub hnyiab) nrog rau kev ua haujlwm ntawm lub voj voog (ua haujlwm thaum muaj hluav taws).

Tau ntawv pov thawj rau thaj chaw muaj kev phom sij (Thaj Chaw 0/1/2) nrog rau kev ntsuas xws li FE180 (180 feeb ntawm kev ciaj sia nyob hluav taws) thiab LSZH sheathing.

Kawm paub seb IS cov xov hluav taws kub ntes tau hluav taws li cas yam tsis ua rau lawv.

Cov xov hluav taws xob uas muaj kev nyab xeeb yog xiav (RAL 5015) raws li IEC 60079-14 rau kev pom tam sim ntawd hauv thaj chaw muaj kev phom sij. Cov xim code no tso cai rau cov kws hluav taws xob kom paub qhov txawv ntawm IS circuits thiab cov xov hluav taws xob uas tsis yog IS - tiv thaiv kev sib txuas tsis raug ntawm lub zog txaus ntshai. Kawm txog tus qauv, kev zam, thiab cov qauv xaiv.
