1.CM moto rating
CM parizvino ndiyo inonyanya kushandiswa murazvo wekudzoreredza nhanho yetambo tambo.Chiyero chayo chekuedza ndeye UL 1581. Maererano netsanangudzo, chidimbu chiduku cheCm-class cable cable chichabuda kunze mukati me5 metres yekupisa kupararira.
Parizvino, iyo yekunze sheath yeCM-kirasi tambo network tambo dzinonyanya kugadzirwa nePVC uye iyo insulation layer inogadzirwa nepamusoro-density PE.Kana yapiswa, inoburitsa halogen ine muchetura, utsi uye kupisa kwakawanda.CM-class cable inowanzoshandiswa pakumhanya yakachinjika pauriri humwe, uye inowanzowanikwa muUnited Kingdom, Asia neAustralia.
2.CMR moto rating
Kuchengetedzwa kweCMR moto chiyero chechipiri, icho chinonyanya kuwanikwa nekuvandudza nzvimbo yekudzima yetambo kuti iwane chinangwa chekusabatidza moto.Chiyero chayo chekuedza ndeye UL 1666. Mutsanangudzo, pasi pemamiriro ekumanikidzirwa kupisa fan, bundle yeCMR cable network cables inofanira kudzimwa mukati me 5 mamita ekupisa kwekupisa.
Parizvino, iyo yekunze sheath yeCMR kirasi tambo network tambo yakagadzirwa neakakwira murazvo unodzoreredza PVC zvinhu, uye iyo insulation layer inogadzirwa nepamusoro-density PE zvinhu.Mushure mekupisa kwemurazvo, inoburitsa muchetura halogenated gasi (chlorine gasi) uye mhute inotungamira, iyo ichakurumidza kupedza okisijeni mumhepo uye kuita kuti murazvo uende kunze. CMR class cabling inoshandiswa zvakanyanya mumhepo inofefetera muma mains akaparadzaniswa nemuviri kubva. iyo cabling system, kureva mukati vertical mains subsystem, uye inowanikwa muAsia neAustralia.
3.CMP moto rating
Iyo CMP moto chiyero ndiyo yakachengeteka.Iyo ine murazvo wakakwana wemoto uye haibudise huwandu hukuru hwehutsi hunokatyamadza kana ichitsva.CMP test standard ndeye UL 910. Maererano neUL tsanangudzo, bundle reCMP cable uye network cables dzinofanira kuzvidzima mukati me 5 metres yekupisa kupararira pasi pe mamiriro ekumanikidzwa kwakanyanya kupisa nemafeni.
Iyo yekunze sheath yeCMP class cable waya inogadzirwa nefluorine (yakadai sePTFE PTFE, FEP fluorinated ethylene propylene), iyo ine yakakwirira decomposition tembiricha uye ignition point.Nekuti CMP cable network cable inogona kumisa kupararira kwekupisa, inotumira kune kuderedza utsi uye chepfu, kunyangwe paine moto, kana muchivako chizere nekupisa kwakawanda nekuda kwetambo network uye utsi kana chepfu inokuvadza, saka giredhi CMP tambo network tambo inoshandiswa mune yekufemesa duct kana mhepo inobata midziyo inoshandiswa. air circumfluence pressurization system, inowanikwa muCanada neUnited States.
4.DongguanWenchangElectronic Co., Ltd.mugadziri weChina ane CM, CMR, CMP certification.
CMR kirasi (vertical combustion bvunzo) Aya ndiwo ekutengesa giredhi tambo muiyo UL standard.Chengetedzo chiyero ndeye UL1666.Iko hakuna hutsi density yakatarwa uye ivo vanowanzo shandiswa kune pasi yakatwasuka uye yakachinjika wiring.
CMP kirasi (Stei Sodium Duct Test) ndiyo inonyanya kudiwa tambo muUL moto kuchengetedza mwero.Inowanzoiswa mumhepo reflux pressurization systems inoshandiswa mumhepo yekufambisa ducts kana mhepo inobata michina.Inotenderwa muCanada neUnited States.
5.Kusiyana pakati peCM, CMR neCMP:
CM, CMR uye CMP inosiyana pachiyero chemoto, mamiriro ekupisa uye ekunze sheath zvinhu.Mukuwedzera, ivo vanosiyana zvakanyanya mumutengo uye nzvimbo yekushandisa.
(1) Musiyano wemutengo.
Iyo yekunze sheath yeCM tambo uye CMR tambo yakagadzirwa nePVC zvinhu, nepo CMP tambo yakagadzirwa nefluorine zvinhu, saka mutengo weCMP tambo unodhura zvakanyanya kupfuura uya weCM tambo uye CMR tambo.
(2) Misiyano munzvimbo dzekushandisa
Kazhinji, CM tambo inoshandiswa muyaya yakachinjika wiring yekusimudza zvivakwa uye makamuri anofefetera mune dzimwe nharaunda, CMR inogona kushandiswa muya yakatwasuka wiring yekusimudza ekuvaka uye vertical ndima, uye CMP inogona kushandiswa mune yakatwasuka wiring yemhepo ducts, inflatable. makamuri kana dzimwe nzvimbo dzekutenderera kwemhepo.
