Polyvinyl Chloride Network Cable Khoom (PVC Network Cable Khoom)
KHOOM NTA
1. CM (Kev sib txuas lus dav dav): Cov khoom siv PVC no yog tsim rau kev sib txuas lus dav dav. Nws muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev ua haujlwm zoo rwb thaiv tsev, siab hnav tsis kam thiab tshuaj tiv thaiv corrosion.
2. CMR (Kev sib txuas lus dav dav dav dav): CMR yog cov khoom siv PVC zoo dua qub, uas muaj cov nplaim hluav taws kub hnyiab tau zoo dua li CM, thiab tuaj yeem ua kom qeeb ntawm hluav taws kub thaum muaj hluav taws. Nws yog feem ntau siv nyob rau hauv cov tsev lag luam uas cov cai hauv tsev yuav tsum tau ua kom muaj hluav taws ntau dua.
3. CMP (Kev sib txuas lus dav dav dav dav tuaj yeem dhau los ntawm lub qhov cua): CMP yog cov khoom siv siab tshaj plaws ntawm PVC cable, nrog cov nplaim hluav taws kub siab tshaj plaws, tuaj yeem siv los hla cov cua hauv lub tsev, xws li cua txias qhov cua. . Cov khoom siv no feem ntau siv rau hauv ib puag ncig uas xav tau cov qauv kev nyab xeeb siab heev, xws li tsev kho mob, cov chaw khaws ntaub ntawv, thiab lwm yam.
KEV SIV
Hauv cheeb tsam network cables, xov tooj kab, hauv tsev network cables, high-speed data kis cables, lwm yam kev lag luam thiab kev lag luam, thiab lwm yam.
Yuav ua li cas paub qhov txawv CM, CMR thiab CMP
1. Kev lag luam qib -CM qib (Vertial Tray Flame Test)
Qhov no yog UL tus qauv coj mus muag qib Cable (General Purpose Cable), muaj feem xyuam rau tus qauv kev nyab xeeb UL1581. Qhov kev ntsuam xyuas yuav tsum tau muab ntau cov qauv coj los teeb tsa rau ntawm qhov ntsug 8-taw sawv ntsug thiab hlawv rau 20 feeb nrog lub tshuab hluav taws xob 20KW (70,000 BTU / Hr). Cov txheej txheem tsim nyog yog tias cov nplaim hluav taws tsis tuaj yeem kis mus rau qhov kawg ntawm lub cable thiab tua nws tus kheej. UL1581 thiab IEC60332-3C zoo ib yam, tsuas yog tus naj npawb ntawm cov cables nteg txawv. Kev lag luam qib cables tsis muaj cov pa luam yeeb cov ntsiab lus tshwj xeeb, feem ntau tsuas yog siv rau cov kab kab rov tav ntawm tib lub hauv pem teb, tsis siv rau txoj kab ntsug ntawm hauv pem teb.
2. Main Line class -CMR class (Riser Flame Test)
Qhov no yog UL tus qauv coj mus muag qib Cable (Riser Cable), muaj feem xyuam rau tus qauv kev nyab xeeb UL1666. Qhov kev sim yuav tsum tau tso ob peb cov qauv rau ntawm lub simulated ntsug ncej thiab siv 154.5KW gas Bunsen burner (527,500 BTU / Hr) rau 30 feeb. Cov txheej txheem tsim nyog yog tias cov nplaim taws tsis kis mus rau sab saud ntawm chav tsev siab 12-foot. Cov kab hluav taws xob hauv lub cev tsis muaj cov pa luam yeeb tshwj xeeb, thiab feem ntau yog siv rau cov kab hauv pem teb ntsug thiab kab rov tav.
3. Booster theem -CMP theem (muab cua combustion Test / Steiner TunnelTest Plenum nplaim Test / Steiner TunnelTest)
Qhov no yog qhov xav tau tshaj plaws Cable hauv UL tus qauv tiv thaiv hluav taws (Plenum Cable), tus qauv kev nyab xeeb siv tau yog UL910, qhov kev sim qhia tau hais tias ntau cov qauv tau muab tso rau ntawm cov kab rov tav cua ntawm lub cuab yeej, hlawv nrog 87.9KW roj Bunsen burner. (300,000 BTU/Hr) rau 20 feeb. Cov txheej txheem tsim nyog yog tias cov nplaim hluav taws yuav tsum tsis txhob ntev tshaj li 5 feet ntawm pem hauv ntej ntawm cov nplaim taws ntawm Bunsen. Qhov siab tshaj plaws qhov muag pom qhov ntom ntom yog 0.5, thiab qhov siab tshaj qhov nruab nrab qhov muag pom yog 0.15. Qhov CMP cable no feem ntau yog ntsia rau hauv cov tshuab cua xa rov qab siv rau hauv cov pa cua lossis cov khoom siv cua thiab tau pom zoo siv hauv Canada thiab Tebchaws Meskas. Cov nplaim hluav taws ua haujlwm ntawm FEP / PLENUM cov khoom ua tau raws li UL910 tus qauv zoo dua li cov khoom siv tsis muaj pa taws halogen tsis ua raws li IEC60332-1 thiab IEC60332-3 tus qauv, thiab cov pa luam yeeb muaj tsawg thaum hlawv.
