1.CM chiyero chemoto
Parizvino CM ndiyo inonyanya kushandiswa pakushandisa tambo yemagetsi. Muyedzo wayo wekuyedza iUL 1581. Zvichienderana netsananguro, tambo diki yetambo yemagetsi yemhando yeCm inodzima yega mukati memamita mashanu ekupararira kwemoto.
Parizvino, sheath yekunze yetambo dzetambo dzeCM-class cable network inonyanya kugadzirwa nePVC uye insulation layer yakagadzirwa nehigh-density PE. Kana yapiswa, inoburitsa halogen ine chepfu, utsi uye kupisa kwakawanda. Tambo yeCM-class inowanzo shandiswa kumhanya yakatwasuka pauriri humwe chete, uye inowanikwa muUnited Kingdom, Asia neAustralia.
2.CMR moto chiyero
Kuchengetedzwa kweCMR fire rating ndiyo yechipiri, iyo inonyanya kuwanikwa nekuvandudza nzvimbo yekubatidza yetambo kuti isabatidze. Muyedzo wayo wekuyedza iUL 1666. Mutsanangudzo, pasi pemamiriro ekubatidza kwefeni, bundle reCMR cable network cable rinofanira kudzimwa mukati memamita mashanu kubva pakupararira kwemoto.
Parizvino, sheath yekunze yeCMR class cable network cable yakagadzirwa nezvinhu zvinodzivirira moto zvakanyanya, uye insulation layer yakagadzirwa nezvinhu zvePE zvakanyanya. Mushure mekupiswa kwemoto, inoburitsa gasi rine chepfu rehalogenated (chlorine gas) uye lead vapor, izvo zvinokurumidza kushandisa oxygen mumhepo zvoita kuti murazvo udzime. CMR class cables inoshandiswa zvakanyanya mumafefetering systems muma mains akaparadzaniswa ne cable system, kureva kuti mu interior vertical mains subsystem, uye inowanikwa muAsia neAustralia.
3.CMP moto chiyero
Chiyero chemoto cheCMP ndicho chakachengeteka. Chine murazvo wakakwana uye hachibudisi utsi hwakawanda hune chepfu kana chichitsva. Chiyero cheCMP chekuyedza iUL 910. Sekureva kwetsananguro yeUL, tambo dzeCMP netambo dzenetwork dzinofanira kuzvidzima mukati memamita mashanu kubva pakupararira kwemoto pasi pemamiriro ekumanikidzwa kwemoto nemafeni.
Chidimbu chekunze chewaya yeCMP class cable chakagadzirwa nefluorine (yakadai sePTFE PTFE, FEP fluorinated ethylene propylene), ine tembiricha yakanyanya kuora uye nzvimbo yekupisa. Nekuti waya yeCMP cable network inogona kumisa kupararira kwekupisa, inotuma kunze kuderedza utsi nehupfu, kunyangwe paine moto, uye muchivako hamuna kutsva kwakawanda nekuda kwenetwork yetambo uye utsi kana chepfu inokuvadza, saka waya yeCMP cable network inoshandiswa mumhepo inofambisa mhepo kana michina yekubata mhepo inoshandiswa mumhepo inotenderera kumanikidza, inowanikwa muCanada neUnited States.
4.DongguanWenchangElectronic Co., Ltd.ikambani yeChina inogadzira michina ine CM, CMR, uye CMP certification.
Kirasi yeCMR (bvunzo yekupisa yakatwasuka) Idzi itambo dzemhando yepamusoro dzekutengesa dziri muchiyero cheUL. Chiyero chekuchengetedza iUL1666. Hapana huremu hweutsi hwakatsanangurwa uye dzinowanzo shandiswa pakubatanidza waya dzakatwasuka nedzakatwasuka pasi.
Kirasi yeCMP (Stei Sodium Duct Test) ndiyo tambo inonyanya kudiwa muUL fire safety standard. Inowanzoiswa muma air reflux pressurization systems anoshandiswa muma ventilation ducts kana mumidziyo yekubata mhepo. Inotenderwa muCanada neUnited States.
5. Kusiyana pakati peCM, CMR neCMP:
CM, CMR neCMP zvakasiyana pahuwandu hwemoto, mamiriro ekutsva uye zvinhu zvekunze. Pamusoro pezvo, zvakasiyana zvikuru pamutengo nenzvimbo yekushandisa.
(1) Musiyano pamutengo.
Chikamu chekunze chetambo yeCM netambo yeCMR chakagadzirwa nezvinhu zvePVC, nepo tambo yeCMP yakagadzirwa nezvinhu zvefluorine, saka mutengo wetambo yeCMP unodhura zvakanyanya kupfuura wetambo yeCM netambo yeCMR.
(2) Kusiyana munzvimbo dzekushandisa
Kazhinji, tambo yeCM inoshandiswa mukubatanidza waya dzakatwasuka dzezvikwiriso zvekuvaka nemakamuri anofefeterwa mune dzimwe nzvimbo, CMR inogona kushandiswa mukubatanidza waya dzakatwasuka dzezvikwiriso zvekuvaka nepassage dzakatwasuka, uye CMP inogona kushandiswa mukubatanidza waya dzemhepo dzakatwasuka, makamuri anofefeterwa kana dzimwe nzvimbo dzinotenderera mhepo.
