Parizvino, the the cable industry ajaira kupisa moto (Fire Retardant), LowSmokeHalogenFree (LSOH) kana kuti halogen yakaderera utsi (LSF), isingadziviriri moto (FireResistant), etc., pamwe nekumwe kuita kwemoto kwetambo, dzinonzi pamwe chete setambo isingadziviriri moto.
1. Tambo inodzoreredza moto (Flame Retardant)
Flame retardant cable inoratidzirwa nekunonoka kupararira kwemurazvo pamwe netambo kuitira kuti moto usawedzere.
Nemhaka yemutengo wayo wakaderera, iyo nhamba huru yetambo dzinodzivirira moto dzinoshandiswa mumhando dzetambo.
Ingave tambo imwe chete kana bundle rekuisa mamiriro, tambo inopiswa apo kupararira kwemurazvo kunogona kudzorwa mukati meimwe siyana.
Saka, unogona kudzivirira njodzi huru inokonzerwa netambo yemoto inononoka kupisa, nokudaro kuvandudza mwero wekudzivirira moto wetambo dzetambo.
2. Halogen-isina low-smoke flame retardant cable (LSOH)
Halogen-isina-yakaderera-utsi tambo inoratidzirwa kwete chete neyakanakisa murazvo inodzoreredza zvivakwa asiwo inoumba yakaderera-utsi halogen-isina tambo zvinhu zvisina halogens., ari low corrosive, uye zvine chepfu kana uchitsva, kubudisa hutsi hushoma kwazvo.
Izvi zvinoderedza kukanganisa kumuviri wemunhu, zviridzwa, uye midziyo, uye inofambisa kununurwa nenguva kana moto.
Kunyangwe iyo halogen-isina yakaderera-utsi inodzoreredza tambo ine yakanakisa murazvo wemoto, Corrosion Rishance, uye kuderera kwehutsi, maitiro ayo emagetsi uye emagetsi akashata zvishoma pane tambo dzakajairwa.
3. Yakaderera-halogen yakaderera-inopfungaira moto inodzoreredza tambo (LSF)
Low halogen yakaderera utsi murazvo unodzoreredza tambo yehydrogen chloride kuburitswa uye zviratidzo zveutsi pakati petambo inodzoreredza moto uye halogen-isina tambo yehutsi inodzoreredza..
Low halogen (LowHalogen) Cable zvinhu zvichange zvinewo halogens, asi zvirimo zvakaderera.
Tambo iyi inoonekwa nekusangoita mirazvo inodzoreredza moto chete asiwo kuburitsa hutsi hushoma uye kudzikisa hydrogen chloride emissions panguva yekupisa..
Izvi zvakaderera-halogen, tambo dzepasi-chiutsi-dzinodzoreredza moto dzinowanzogadzirwa ne polyvinyl chloride (Pvc) sechigadziko uye chakagadziriswa neakanyanya kushanda emurazvo retardants, HCL absorbers, uye zvinoderedza utsi.
Saka, iyi murazvo inodzoreredza zvinhu inovandudza zvakanyanya kupisa kweyakajairwa murazvo unodzoreredza PVC zvinhu.
4. Cable isingadziviriri moto (FireResistant)
Moto-inodzivirira tambo inokwanisa kuchengetedza yakajairika kushanda kweimwe nguva yenguva kana murazvo uchipfuta uye inogona kuchengetedza kutendeseka kwemutsara. (CircuitIntergrity).
Tambo dzemoto dzisingadziviriri moto dzinoburitsa utsi hweasidhi shoma kana ichitsva, uye kushanda kwemoto usingadziviriri murazvo wakavandudzwa zvikuru, kunyanya panyaya yekutsva, ichiperekedzwa nemvura spray uye mechanical shock, tambo inogona kuramba ichichengetedza kuvimbika kwekushanda kwemutsara.
5. Flame-retardant cable standards uye mamakisi
Iyo huru tekinoroji zviratidzo zvetambo inobatanidzwa mukuchengetedzeka kwemoto kudzoreredza kwemurazvo we CO2 tambo, kuwanda kweutsi, uye gasi toxicity.
U.S. mitemo yemoto inonyanya kunetseka pamusoro penyaya mbiri dzokutanga, asi Europe neUnited States vane maonero akasiyana zvachose pamusoro pekuchengetedza moto.
Pfungwa yechinyakare yekuAmerica ndeyekuti chisakiso chemoto kugadzirwa kwecarbon monoxide (CO) gasi rine chepfu uye rinozotevera kupisa kuburitswa kubva ku CO kuenda ku CO2 panguva yekupisa. Saka, kudzora huwandu hwekupisa hunoburitswa panguva yekupisa kunogona kuderedza njodzi yemoto.
Europe yagara ichigutsikana kuti huwandu hwehalogenated acid (HCL) yakasunungurwa panguva yekupisa, kuora kwegasi, kuwanda kweutsi, uye huturu hwegasi ndizvo zvinhu zvikuru zvinotaridza kana vanhu vachikwanisa kubva panzvimbo yemoto zvakachengeteka.
