Kana dziri waya netambo dzine voltage shoma, dzakakamurwa kuita mapoka maviri zvichienderana nechinangwa chadzo: waya dzekuvaka netambo dzemagetsi. Muwaya dzekuvaka, dzaive waya dzakaputirwa nerabha dzakagadzirwa neasphalt dzakagadzirwa nerabha kubva kuma1960. Kubva kuma1970, dzakatsiviwa zvachose netambo dzepurasitiki dzePVC. Mamiriro ezvinhu mumitsetse yemidziyo yemagetsi akafanana neaya ari mumitsetse yekuvaka, iyo pakutanga yaidzorwa nerabha yechisikigo, asi yakatsiviwa zvakanyanya netambo dzePVC kuma1970. Mamiriro aya haasi esainzi uye haana musoro maererano neindasitiri yetambo uye sarudzo dzevashandisi. Mazuva ano, tambo dzakasiyana dzemagetsi, kunyanya tambo dzinobatanidza dzinodiwa pamidziyo yemumba inokura, dzinofanira kuchinja mamiriro ezvinhu aripo ekushandiswa nepurasitiki yePVC uye kutsiva netambo dzerabha. Nekuti tambo dzerabha dzine zvakanakira zvakasiyana senge kupfava, kunzwa kwakanaka kweruoko, kusatya kupisa, uye kusanyunguduka, hadzina kuenzana netambo dzepurasitiki. Nekuda kwezvakanakira zvakawanda zvisina rabha yekugadzira, CPE inogona kushandiswa zvakanyanya mukugadzira tambo dzemagetsi dzemumba nedzimwe tambo dzinochinjika dzemidziyo yemagetsi. CPE ine hunhu hwakakwana hwehunyanzvi, hwakadai sehunononoka moto zvakanyanya uye hunodzivirira mafuta zvakanyanya, hunhu hwemuviri uye hwemakanika (kureva hunhu hwemakanika), hunodzivirira kupisa zvakanyanya, hunodzivirira ozone, hunodzivirira mamiriro ekunze, hunhu hwakanaka hwemagetsi, uye hunhu hwakanaka hwekugadzirisa. Inogona kushandiswa mumichina yekugadzira rabha, uye zvinhu zverabha hazvitsve zvakanyanya. Zvinhu zveCPE hazvizoore mushure memakore akati wandei ekuchengetedza, Zvinhu zverabha zvine vulcanizing agents zvinogona kuchengetwa kwemakore 1-2 pasina kuora pasi pemamiriro ekuchengetedza ari nani.
Muchidimbu, kushandiswa kweCPE muindasitiri yetambo dzepamhepo, ndiko kuti, kutsiva CR neCPE, inzira iri kushandiswa muindasitiri yetambo dzepamhepo. Izvi hazvingorerutsi chete kusawirirana kwekudiwa kweCR, asi zvinoderedza zvakanyanya mutengo wezvigadzirwa zvetambo, zvinovandudza mabhenefiti ehupfumi eindasitiri yetambo, asiwo zvine kukosha kukuru mukuvandudza mhando dzezvigadzirwa zvetambo uye kuita kuti mhando dzetambo dzisiyane.
