Kuba iintambo zisetyenziswa ekwembiweni kweemeko ezinzima kunye nendawo engcolileyo, zigcwele igesi kunye ne-smut, zibonakaliswa ngokulula, iintambo zamandla ezithintela ilangatye zeplastiki ezigqunyiweyo azinazo nje kuphela iimpawu ezikhankanyiweyo kwisahluko sokuqala sale ncwadi yemiyalelo, kodwa zikwanazo neempawu zokuthintela ilangatye eliphezulu. Phakathi kwazo, leyo ineendawo eziphezulu ezinqamlezileyo ezingama-50mm nangaphezulu kufuneka idlule kuvavanyo lokutsha lwe-A type Collecting Electric Wire & cable. Ukuba ingaphantsi kwama-50mm², kufuneka idlule kuvavanyo lokutsha lwe-B type collecting wire & cable.
1. Ubushushu obuphezulu bokusebenza
2. Uzinzo oluqinileyo lwenkonzo kunye nokumelana nomlilo, okuqinisekisa ngokufanelekileyo ubomi benkonzo yentambo.
3. Ubungqina bokuqhushumba
4. Ububanzi obuncinci obungaphandle
5. Amandla aphezulu oomatshini
6. Umthamo omkhulu wokuthwala wangoku
7. Ukumelana nokugqwala okuphezulu
Olu hlobo lwentambo lufanelekile ukusetyenziswa ekufakelweni okusisigxina kwimigca yokuhambisa/yokusasaza kwii-voltage ezilinganisiweyo ezingaphezu kwe-10kV ezifana nendawo ukusuka kwigumbi lokusasaza eliphakathi ukuya kwigumbi le-electromechanical, i-movab-e transformer substation, i-comprehensive mining workshop kunye ne-switchgear. Le ntambo inophawu lokubanda komlilo okufutshane.

2.2 Ubushushu obuphezulu xa ukusebenza okuqhelekileyo kunye nokujikeleza okufutshane (ixesha eliphezulu akufuneki lidlule ii-5s)
Kwintambo yamandla ethintela ilangatye egqunywe yiPVC engama-70℃, ubushushu obuphezulu abufanele budlule kwi-160℃ xa kukho i-short circuit. Kwintambo yamandla ethintela ilangatye egqunywe yiXLPE engama-90℃, ubushushu obuphezulu abufanele budlule kwi-250℃ xa kukho i-short circuit.
2.3 Iimeko zokufakelwa kweentambo
