1. Ukuze kuqinisekiswe ukusebenza okungangeni manzi kanye nesikhathi eside, kunconywa ukusebenzisa amashubhu okunciphisa ukushisa anezindonga ezimbili kanye namashubhu afaka insulating.
2. Ukuze kuqinisekiswe ukuthi ukuhlangana kungakwazi ukumelana nokucindezela okuthile, kunconywa ukuthi ungeze i-sheath ukuze uthuthukise ukufakwa nokuvikela.
3. I-tape yokuzinamathisela (noma i-tape yokushisa encibilikayo engangeni manzi) esetshenzisiwe iwumkhiqizo we-voltage ephezulu ukuze kuqinisekiswe ukuphepha kwe-insulation.
4. Lapho wakha, kungcono kakhulu ukusebenzisa indlela yokuxhuma enyakazayo (okungukuthi, ikhebula alidingi ukunqunywa futhi lifakwe ngobunono).
