SANS 1713--- Tambo dzemagetsi -Medium voltage aerial bundled conductors for voltages kubva pa3,8/6,6 kV kusvika 19/33 kV
6.6kV-22kV
Conductor: Aluminium, denderedzwa yakasungwa uye yakasungirirwa.
Conductor Kuongorora: Yakawedzera thermosetting semi-conductor layer.
Insulation: XLPE thermosetting zvinhu.
Insulation Screening: Semi conducting screen: Extruded thermosetting semi-conducting layer, yakaiswa pasi pe tepi inoputika semi-conducting tepi yekusapinda mvura.
Simbi yesimbi: Yakapfava yakapfava waya yemhangura uye / kana tepi yemhangura yakaiswa helically, kana tepi yealuminium yakaiswa kureba yakasungirirwa kune yekunze PE sheath.
Outer sheath: Yakawedzera dema PE sheath, kana PVC pane chaiyo zvinodiwa nevatengi.
Simbi Messenger: 50 kana 70 mm²galvanized steel stranded waya, yakafukidzwa nedema PE, kana PVC pane chaiyo mutengi zvinodiwa.
