Isicelo

I-15kV I-Aerial Overhead Electric Cables (intambo yesihlahla nentambo yesikhala) I-AAAC (icwecwe) i-XLPE enezingqimba ezi-3 ihloselwe ukusetshenziswa kumasistimu okusabalalisa aphezulu aphezulu kanye nakwesibili alinganiselwe ngo-15 kV (okuyigama) ngokuvamile ukuvimbela amaphutha ngenxa yokuxhumana noma lapho isikhala kunqunyelwe.Isistimu enezingqimba ezi-3 ezimelana nethrekhi ivimbela ama-short-circuits kanye nama-flashavers esimweni sokuxhumana nezihlahla noma izilwane zasendle.Uma ifakwe ngendlela efanele, lesi simiso sisebenza ngempumelelo ekuvimbeleni ukucisha kwesistimu, ukulimala, noma imililo ngenxa yokuwa kwezihlahla noma amagatsha.

Ezokwakha

Abaqhubi:
Aluminium 1350-H19 conductors

I-Stranding:
Amakhondaktha e-Aluminium aboshwe ngokujulile azungeze umgogodla wensimbi.

Ukuqinisa:
Insimbi eyinsimbi, efakwe uthayela ku-zinc-coating.

Ijakhethi Langaphandle:
I-polyethylene ivikela umqhubi esimweni sezulu noma ezintweni ezingase zinciphise intambo kagesi.Isembozo se-polyethylene sitholakala ku-polyethylene ephezulu ye-molecular noma i-polyethylene exhunywe cross.

Imininingwane

Lawa makhebula asemoyeni amaphakathi i-AAAC 3-ungqimba we-Track-resistant XLPE akhiqizwa futhi ahlolwe ukuze ahlangabezane noma adlule amazinga alandelayo:
-ASTM B 398 – Aluminium-Alloy 6201-T81 kanye ne-6201-T83 Wire Yezinjongo Zogesi
-ASTM B 399 – Concentric-Lay-Stranded Aluminium-Alloy 6201-T81 Conductors
-ASTM D2656 -I-Polyethylene Insulation exhunywe ngokuphambana yocingo nekhebula Ikalwe ngo-2001 kuya ku-35000V
-ICEA S-121-733 - Intambo Yesihlahla kanye ne-Messenger Esekelwe Ikhebula le-Spacer
