Kana dziri waya dzepasi-voltage uye tambo, dzinonyanya kukamurwa kuita zvikamu zviviri zvinoenderana nechinangwa chavo: waya dzekuvaka uye waya dzemagetsi emidziyo.Muwaya yekuvaka, yaive yakasikwa rabha insulated yakarukwa asphalt coated waya kutanga kuma1960s.Kubva kuma1970, yakatsiviwa zvachose nePVC plastiki waya.Mamiriro ezvinhu mumitsara yemidziyo yemagetsi akafanana neaya mumitsara yekuvaka, iyo yakatanga kudzorwa nerabha yechisikigo, asi yakatsiviwa netambo dzePVC muma1970s.Mamiriro ezvinhu aya haasi esainzi uye haana musoro maererano neindasitiri yetambo uye sarudzo dzevashandisi.Mazuva ano, tambo dzemagetsi akasiyana siyana, kunyanya tambo dzekubatanidza dzinodiwa pamidziyo yemumba inokura, dzinofanira kushandura mamiriro ezvinhu ekuti anotongwa nePVC plastiki uye kuatsiva netambo dzerabha.Nekuti tambo dzerabha dzine zvakanakira zvakasiyana sekupfava, kunzwa zvakanaka kwemaoko, kusatya kupisa, uye kusanyungudika, hazvienzaniswi netambo dzepurasitiki.Nekuda kwezvakanaka zvakawanda izvo synthetic rubber isina, CPE inogona kushandiswa zvakanyanya mukugadzira tambo dzemagetsi epamba uye mamwe tambo anochinjika emidziyo yemagetsi.CPE ine hunyanzvi hwekuita zvinhu, senge kudzoreredza moto uye kuramba kwemafuta kwakanyanya, muviri uye michina zvinhu (kureva mechanical properties), yakanaka kupisa kuchembera, ozone kuramba, kusamira kwemamiriro ekunze, kunaka kwemagetsi zvinhu, uye kuita kwakanaka kwekugadzirisa.Inogona kushandiswa mune zvakajairika rabha kugadzirisa michina, uye iyo rubha zvinhu haiwanzo kupisa.CPE mbishi zvinhu hazvizoparare mushure memakore akati wandei ekuchengetedza, Rubber zvinhu zvine vulcanizing agents zvinogona kuchengetwa kwemakore 1-2 pasina kushatisa pasi pemamiriro ekuchengetedza ari nani.
Muchidimbu, kushandiswa kweCPE muindasitiri yematambo epamhepo, ndiko kuti, kutsiva CR neCPE, muitiro muindasitiri yematambo epamhepo.Izvi hazvingoderedze kupokana-kudiwa kweCR, zvinoderedza zvakanyanya mutengo wezvigadzirwa zvetambo, zvinovandudza mabhenefiti ehupfumi hweindasitiri yematambo, asi zvakare zvine kukosha kwakadzama mukuvandudza giredhi rezvigadzirwa zvetambo uye kuwana kusiyanisa kwemhando dzetambo.
