Ngoba izintambo zisetshenziswa ekumbiweni kwezimo eziyinkimbinkimbi kanye nendawo embi, egcwele igesi kanye ne-smut, ukuvezwa okulula, izintambo zikagesi zepulasitiki ezivikelwe ezivimbela ilangabi azinazo nje kuphela izakhiwo ezishiwo esahlukweni sokuqala sale ncwadi, kodwa futhi zinempahla ye-langabi elivimbela ilangabi eliphezulu. Phakathi kwazo, leyo enendawo yayo ephezulu engama-50mm nangaphezulu kufanele idlule ekuhlolweni kokushiswa kwentambo kagesi yohlobo lwe-A Collecting Electric Wire & cable. Uma ingaphansi kwama-50mm², kufanele idlule ekuhlolweni kokushiswa kwentambo kagesi yohlobo lwe-B collecting kanye nekhebula.
1. Izinga lokushisa eliphezulu lokusebenza
2. Ukuqina kwenkonzo eqinile kanye nokumelana nomlilo, okuqinisekisa ngempumelelo impilo yenkonzo yekhebula.
3. Ubufakazi bokuqhuma
4. Ububanzi obuncane bangaphandle
5. Amandla aphezulu okusebenza ngomshini
6. Umthamo omkhulu wokuthwala wamanje
7. Ukumelana nokugqwala okuphezulu
Lolu hlobo lwekhebula lufanele ukusetshenziswa ekufakweni okuhleliwe emigqeni yokudlulisa/yokusabalalisa yama-voltage alinganiselwe angaphezu kuka-10kV njengendawo esuka ekamelweni lokusabalalisa eliphakathi kuya ekamelweni le-electromechanical, isiteshi esincane se-transformer se-movab-e, indawo yokusebenzela yezimayini ephelele kanye ne-switchgear. Ikhebula linomumo ofana nowokuthi lingabi namandla okushisa ilangabi.
Ikhebula lamandla eli-1 le-PVC elivikela umlilo elifakwe i-colliery (MT818.12-1999) Imininingwane kanye nenani libonakala kuThebula 2-1

2.2 Izinga lokushisa eliphezulu kakhulu uma ukusebenza okuvamile kanye nomjikelezo omfushane (isikhathi esiphezulu akufanele sidlule amasekhondi angu-5)
Kwikhebula lamandla elibamba umlilo eliyi-PVC elingu-70℃, izinga lokushisa eliphezulu akufanele lidlule u-160℃ uma kune-short circuit. 90℃ kwikhebula lamandla elibamba umlilo eliyi-XLPE elibamba umlilo eliyi-short circuit, izinga lokushisa eliphezulu akufanele lidlule u-250℃ uma kune-short circuit.
2.3 Izimo zokufakwa kwamakhebula
2.3.1 Izinga lokushisa elizungezile akufanele libe ngaphansi kuka-0℃.
