Ngokuphathelele i-low-voltage iingcingo kunye neentambo, zihlulwe ngokukodwa zibe ngamacandelo amabini ngokwenjongo yazo: iingcingo zokwakha kunye neengcingo zezixhobo zombane.Kucingo lolwakhiwo, yayiyirabha yendalo egqunywe ngocingo olulukiweyo olulukiweyo lwe-asphalt kwangoko ngeminyaka yoo-1960.Ukusukela ngeminyaka yee-1970, ithathelwe indawo ngokupheleleyo ngeengcingo zeplastiki zePVC.Imeko kwimigca yezixhobo zombane iyafana naleyo kwimizila yokwakha, eyayiqale ilawulwa yirubha yendalo, kodwa yatshintshwa ubukhulu becala ziintambo zePVC ngeminyaka yoo-1970.Le meko ayihambelani nenzululwazi kwaye ayikho ngqiqweni ngokweshishini lentambo kunye nokukhetha kwabasebenzisi.Kule mihla, iintambo zezixhobo zombane ezahlukahlukeneyo, ingakumbi iintambo zokuqhagamshela ezifunekayo kwizixhobo zekhaya ezikhulayo, kufuneka zitshintshe imeko yangoku yokulawulwa yiPVC yeplastiki kwaye endaweni yazo kufakwe iintambo zerabha.Ngenxa yokuba iintambo zerabha zineengenelo ezikhethekileyo ezifana nokuthamba, ukuvakala kakuhle kwesandla, ukungoyiki ubushushu, nokunganyibiliki, azinakuthelekiswa neentambo zeplastiki.Ngenxa yeenzuzo zayo ezininzi irabha yokwenziwa ayinayo, i-CPE ingasetyenziswa ngokubanzi ekwenzeni iintambo zombane zasekhaya kunye nezinye iintambo eziguquguqukayo zezixhobo zombane.I-CPE ineempawu zobugcisa ezibanzi, ezinjengokuncitshiswa komlilo okugqwesileyo kunye nokuxhathisa okuphezulu kwe-oyile, iipropathi zomzimba nezomatshini (oko kukuthi, iipropathi zoomatshini), ukumelana nokuguga kobushushu, ukumelana ne-ozone, ukuxhathisa kwemozulu, iipropati zombane ezilungileyo, kunye nokusebenza kakuhle kokusebenza.Ingasetyenziswa kwisixhobo sokwenza irabha ngokubanzi, kwaye izinto zerabha aziqhelekanga ukutshisa.Izinto eziluhlaza ze-CPE aziyi konakala emva kweminyaka emininzi yokugcina, izinto zeRubber ezinama-agent ahlanjululwayo zingagcinwa iminyaka eyi-1-2 ngaphandle kokuwohloka phantsi kweemeko ezingcono zokugcina.
Isishwankathelo, ukusetyenziswa kwe-CPE kushishino lweentambo ze-intanethi, oko kukuthi, ukubuyisela i-CR nge-CPE, ngumkhwa kushishino lweentambo ze-intanethi.Oku akugcini nje ukunciphisa ukuchasana kwemfuno yokubonelela nge-CR, kunciphisa kakhulu ixabiso leemveliso zentambo, kuphucula inzuzo yezoqoqosho kushishino lweentambo, kodwa kunokubaluleka okunzulu ekuphuculeni umgangatho weemveliso zentambo kunye nokufezekisa ukuhlukahluka kweentlobo zeentambo.
