1.CM ukukala komlilo
I-CM okwangoku lelona nqanaba lixhaphakileyo lokubuyiswa komlilo kwintambo yentambo.Umgangatho wayo wokuvavanya ngu-UL 1581. Ngokwenkcazo, i-bundle encinci ye-Cm-class cable cable iya kuphuma ngokuzenzekelayo ngaphakathi kweemitha ezi-5 zokusasazwa komlilo.
Okwangoku, i-sheath yangaphandle ye-CM-class cable network cables is most made of PVC and the insulation layer is made of high-density PE.Xa itshisiwe, iya kukhupha i-halogen enetyhefu, umsi kunye nobushushu obuninzi be-cable.CM-class cable isetyenziswa ngokubanzi ekusebenzeni ngokuthe tye kumgangatho ofanayo, kwaye ifumaneka ngokuqhelekileyo e-United Kingdom, e-Asia nase-Australia.
2.CMR ukukala umlilo
Ukukhuselwa komgangatho womlilo we-CMR ngowesibini, eyona nto iphunyezwa ngokuphucula indawo yokucima intambo ukufezekisa injongo yokungatsha.Umgangatho walo wokuvavanya ngu-UL 1666. Kwinkcazo, phantsi kweemeko zokutsha kwefeni ngenkani, inqwaba yeentambo zentambo ze-CMR zenethiwekhi kufuneka zicinywe ngaphakathi kweemitha ezi-5 zokusasazwa komlilo.
Okwangoku, i-sheath yangaphandle ye-CMR yeklasi yentambo yentambo yentambo yentambo yenziwe nge-PVC ephezulu ye-flame retardant, kunye ne-insulation layer yenziwe ngezinto eziphezulu ze-PE.Emva kokutshiswa komlilo, kuya kukhupha igesi enetyhefu ye-halogenated (igesi ye-chlorine) kunye nomphunga okhokelayo, oya kudla ngokukhawuleza i-oksijini emoyeni kwaye wenze ilangatye liphume.I-CMR iklasi ye-cabling isetyenziswa ngokubanzi kwiinkqubo zokungenisa umoya kwiinqununu ezihlukaniswe ngokwasemzimbeni. inkqubo yecabling, okt kumbindi wendlela esezantsi ethe nkqo, kwaye iqhele ukufunyanwa eAsia naseOstreliya.
3.CMP ukukala komlilo
Ireyithingi yomlilo ye-CMP yeyona ikhuselekileyo.Inokubuyiswa komlilo ogqibeleleyo kwaye ayikhuphi umsi omninzi onetyhefu xa utshisa.Umgangatho wovavanyo lwe-CMP ngu-UL 910. Ngokwenkcazo ye-UL, i-bundle ye-CMP cable kunye neentambo zenethiwekhi kufuneka zicime ngokwazo ngaphakathi kweemitha ezi-5 zokusasazwa kokutsha phantsi kwe-diffusion. iimeko zokutshiswa ngamandla okunyanzeliswa ngabalandeli.
I-sheath yangaphandle yeklasi ye-CMP yocingo lwentambo yentambo yenziwe nge-fluorine (efana ne-PTFE PTFE, i-FEP e-fluorinated ethylene propylene), enobushushu obuphezulu bokubola kunye nendawo yokucima. ukunciphisa umsi kunye netyhefu, nangona kukho umlilo, okanye kwisakhiwo sigcwele ukutshisa okukhulu ngenxa yothungelwano lwentambo kunye nomsi okanye ityhefu eyingozi, ngoko ke intambo ye-CMP ye-cable network cable isetyenziswa kumbhobho wokungenisa umoya okanye izixhobo zokuphatha umoya ezisetyenzisiweyo. inkqubo yoxinzelelo lwe-air circumfluence, eqhelekileyo eCanada nase-United States.
4.DongguanWenchangElectronic Co., Ltd.ngumvelisi waseTshayina oneCM, CMR, CMP isatifikethi.
Iklasi ye-CMR (uvavanyo lokutshisa oluthe nkqo) Ezi ziintambo zebakala lorhwebo kumgangatho we-UL.Umgangatho wokhuseleko yi-UL1666.Akukho nkcazelo yoxinaniso lomsi kwaye zisetyenziswa ngokubanzi kumgangatho othe nkqo kunye nocingo oluthe tye.
Iklasi ye-CMP (i-Stei Sodium Duct Test) yeyona ntambo ifunekayo kwi-UL yomgangatho wokhuseleko lomlilo.Ngokuqhelekileyo ifakwe kwiinkqubo zoxinzelelo lwe-air reflux ezisetyenziselwa kwiindlela zokungenisa umoya okanye izixhobo zokuphatha umoya.Ivunyiwe eCanada nase-United States.
5.Umahluko phakathi kweCM, CMR kunye neCMP:
I-CM, i-CMR kunye ne-CMP ziyahluka kumlinganiselo womlilo, imeko yokutsha kunye nempahla yangaphandle ye-sheath.Ukongeza, bahluke kakhulu kwixabiso kunye nendawo yesicelo.
(1)Umahluko kwixabiso.
I-sheath yangaphandle ye-CM cable kunye ne-CMR cable yenziwe ngezinto ze-PVC, ngelixa intambo ye-CMP yenziwe ngezinto ze-fluorine, ngoko ke ixabiso lentambo ye-CMP libiza kakhulu kunelo lentambo ye-CM kunye ne-CMR cable.
(2) Umahluko kwiindawo zesicelo
Ngokubanzi, intambo ye-CM isetyenziselwa i-wiring ethe tyaba yokunyuswa kwesakhiwo kunye namagumbi anokuvuthela kwezinye iindawo, i-CMR ingasetyenziselwa i-wiring ethe nkqo yokunyuswa kwesakhiwo kunye neepaseji ezithe nkqo, kwaye i-CMP ingasetyenziselwa i-wiring ethe tyaba ye-air ducts, i-inflatable. amagumbi okanye ezinye iindawo zokujikeleza komoya.
