Xa EmailRaws li peb- lossis plaub-tus neeg xyuas pib fais fab cables ntsuas 600 volts, 90 deg.C. nyob rau hauv qhov chaw qhuav lossis ntub dej.
Kev pom zoo tshwj xeeb rau kev teeb tsa hauv cable tais raws li Tshooj 340 ntawm NEC.Hom TC cables raug tso cai siv rau hauv Chav Kawm I Division 2 qhov chaw muaj kev phom sij rau NEC.Cables tej zaum yuav raug ntsia rau hauv huab cua dawb, raceways los yog ncaj qha faus, nyob rau hauv ntub los yog qhuav qhov chaw.Tag nrho cov cables thaum siv raws li NEC, ua tau raws li OSHA cov cai.
Tus neeg xyuas pib ntawm lub cable yuav yog tooj liab lossis txhuas lossisaluminium alloy.Tus naj npawb ntawm cov cores tuaj yeem yog 1, 2, 3, nrog rau 4 thiab 5 (4 thiab 5 feem ntau yog cov kab hluav taws xob tsawg).
Lub armoring ntawm lub cable yuav muab faib ua steel hlau armoring thiab steel daim kab xev armoring, thiab cov khoom uas tsis yog-sib nqus armoring siv nyob rau hauv ib leeg-core AC cable.
Kev tsim kho:
Stranded copper conductors, XLP (Cross-Linked Polyethylene) insulated, Txoj Kev 1 - Table E1 lossis E2 xim-coded, lossis Txoj Kev 4 theem- txheeb xyuas.Insulated conductors cabled nrog ib tug stranded tooj liab grounding conductor nyob rau hauv ib tug interstice, cable daim kab xev, PVC (Polyvinyl Chloride) tsho, nto luam tawm.
Qauv:
Conductors ua raws li ASTM B-3 & B-8.
Tus neeg xyuas pib ua raws li UL Standard 44, thiab tau pom zoo raws li Hom XHHW-2.
TC Hom Tais Cable rau Tshooj 340 ntawm NEC.
Cables haum rau Sunlight Resistant daim ntaub ntawv.
Cables tsim kom dhau qhov kev xeem IEEE-383 & IEEE-1202 nplaim taws.
Cables ua tau raws li cov cai ntawm ICEA S-95-658 / NEMA WC70.
