- Ukunqamula / ama-isolators
- Ukulayisha ukushintshwa kwekhefu (lbs)
- Ukushintshwa komhlaba
c.
Lokhu kubaqhubi be-Copper / Aluminium abasetshenziselwa ukusabalalisa amandla.
d.
Ukufakwa kwezinto kwanamuhla kuhlanganiswe ne-IEDS (amadivaysi e-elekthronikhi ahlakaniphile) ahambisanaIEC 61850.
- -Gqamile
- Ukwahlukanisa
- Ukuvikelwa Kwebanga
e.
Vimbela izimbotshana ze-transvoltages ezintweni ezilimazayo.
f.
Amabhange ebhethri, amashaja webhethri, nezinhlelo zokukhanyisa.
3. Ithebula lezobuchwepheshe

4. Ukucatshangelwa Kwemiklamo Yokubuyiselwa
Ukuqamba indawo ephezulu yokusebenza kufaka izingqimba eziningana:
a.
Bala imithwalo ye-Peak ku-Usayizi Orfapy ngendlela efanele.
b.
Qinisekisa ukudluliselwa kanye nabaqhekezi basebenza ngokukhetha ukuhlukanisa isigaba esinephutha kuphela.
c.
Nquma ukuthi uzosebenzisa yini-ngaphandlenomai-switchgear yangaphakathi, I-GIS (igesi efakwe igesi), noma i-AIS (AIR efakiwe).
d.
Faka phakathi ukuqina kokuzamazama komhlaba, umoya, nokulinganisa kokulinganisa kokuqina.
e.
Ukuvunyelwa okwanele nokuphepha kokuphepha kubalulekile.

I-5. Izicelo ze-11/33 KV
- Amapaki Wezimboni
- Izindawo ezinkulu zezentengiso
- Amapulazi elanga kanye nomoya
- Ukufakwa kukahulumeni
- Ama-grid kagesi asemadolobheni nase-peri-Urban
Lokhu kufakazelwa kuvame ukusetshenziselwa ukondla ama-11kv Ring Main Units (Rmus) ezindaweni eziminyene.
6. Ukuhambisana namazinga wamazwe aphesheya
-Nkeukubusisakumele uvumelane ne:
- IEC 62271-100 / 200 (i-high-voltage switchchear)
- Ngu-1180 (ama-transformers okusabalalisa)
- IEEE 1584 (Ukuhlaziywa kwe-ARC Flash)
- I-ISO 45001 (ukuphepha emsebenzini)
7. Ukufakwa kokufakwa kwezinyathelo & izinyathelo zokuthumela
a.
Ucwaningo, ukumbiwa, kanye nezisekelo zokhonkolo.
b.
Ukubekwa kwama-transformers, amaphaneli, ama-breakers, kanye nama-ducts webhasi.
c.
Ukuqinisekisa ukuhlolwa okufanelekile kanye nokuhlolwa kwentambo.
d.
Ukuhlolwa kwenani le-IR, umjovo wamabanga aphansi / wesibili, izilungiselelo ezidluliselwe.
