Ngokuphathelele iingcingo kunye neentambo ezine-voltage ephantsi, zahlulwe kakhulu zibe ngamacandelo amabini ngokwenjongo yazo: iingcingo zokwakha kunye neengcingo zezixhobo zombane. Kwingcingo yokwakha, yayiyingcingo yendalo egqunywe nge-asphalt eyenziwe ngerabha kwasekuqaleni kweminyaka yoo-1960. Ukususela ngeminyaka yoo-1970, ithathelwe indawo ngokupheleleyo ziingcingo zeplastiki zePVC. Imeko kwimigca yezixhobo zombane iyafana naleyo kwimigca yokwakha, eyayilawulwa yirabha yendalo, kodwa yathathelwa indawo kakhulu ziintambo zePVC ngeminyaka yoo-1970. Le meko ayisiyonzululwazi kwaye ayinangqiqo ngokweshishini leentambo kunye nokukhetha kwabasebenzisi. Kule mihla, iintambo ezahlukeneyo zezixhobo zombane, ngakumbi iintambo zokudibanisa ezifunekayo kwizixhobo zasekhaya ezikhulayo, kufuneka zitshintshe imeko yangoku yokuba zilawulwa yiplastiki yePVC kwaye zithathelwe indawo ngeengcingo zerabha. Ngenxa yokuba iintambo zerabha zineengenelo ezikhethekileyo ezifana nokuthamba, ukuvakalelwa kakuhle kwesandla, ukungabi naloyiko lobushushu, kunye nokunganyibiliki, azinakuthelekiswa neengcingo zeplastiki. Ngenxa yeengenelo zayo ezininzi ezingenazo irabha yokwenziwa, iCPE ingasetyenziswa kakhulu ekwenzeni iintambo zombane zasekhaya kunye nezinye iintambo eziguquguqukayo zezixhobo zombane. I-CPE ineempawu zobugcisa ezipheleleyo, ezifana nokungacimi kakuhle komlilo kunye nokumelana okuphezulu kweoyile, iimpawu zomzimba nezoomatshini (oko kukuthi, iimpawu zoomatshini), ukumelana okuhle nokuguga kobushushu, ukumelana ne-ozone, ukumelana nesimo sezulu, iimpawu zombane ezilungileyo, kunye nokusebenza kakuhle kokucubungula. Ingasetyenziswa kwizixhobo zokucubungula irabha ngokubanzi, kwaye izinto zerabha azitshisi kakhulu. Izinto eziluhlaza ze-CPE aziyi konakala emva kweminyaka eliqela yokugcina, Izinto zerabha ezinee-agents ze-vulcanizing zingagcinwa iminyaka eli-1-2 ngaphandle kokonakala phantsi kweemeko zokugcina ezingcono.
Ngamafutshane, ukusetyenziswa kwe-CPE kushishino lweentambo ezikwi-intanethi, oko kukuthi, ukuthatha indawo ye-CR nge-CPE, yindlela ethandwayo kushishino lweentambo ezikwi-intanethi. Oku akupheleli nje ekunciphiseni ukuphikisana kwe-CR nokunikezelwa kwempahla, kunciphisa kakhulu iindleko zeemveliso zeentambo, kuphucula iingenelo zoqoqosho kushishino lweentambo, kodwa kukwabaluleke kakhulu ekuphuculeni umgangatho weemveliso zeentambo kunye nokufezekisa ukwahlukahlukana kweentlobo zeentambo.
