Kwiingozi zentambo yentambo ye-ADSS, ukuqhawulwa kwentambo yenye yeengxaki eziqhelekileyo.Kukho izinto ezininzi ezibangela ukuqhawulwa kwentambo.Phakathi kwabo, ukukhethwa kwendawo yekona ye-AS optical cable ingadweliswa njengempembelelo ethe ngqo.Namhlanje siza kuhlalutya ukhetho lwekona lekonaADSS intambo yokubonakumgca we-35KV.
Kukho la manqaku alandelayo kumanqaku ekona yomgca we-35KV:
⑴Akufanelekanga ukukhetha iincopho zeentaba eziphakamileyo, imisele enzulu, iindonga zemilambo, amadama, amawa, amathambeka, okanye iindawo ekulula ukukhukuliseka nokuhlanjwa zizikhukula kunye nokuqokelelana kwamanzi aphantsi.
⑵Ikona yomgca kufuneka ibekwe kumhlaba othe tyaba okanye ithambeka elithambileyo emazantsi entaba, kwaye ulwakhiwo olwaneleyo lweendawo zomgca oqinileyo kunye nokufikelela ngokulula koomatshini bokwakha kufuneka kuqwalaselwe.
⑶Ukukhethwa kwendawo yekona kufuneka kuthathelwe ingqalelo ingqiqo yokucwangciswa kwezibonda zangaphambili nangemuva, ukwenzela ukuba kungabangela ukuba iigiya ezimbini ezikufutshane zibe zikhulu kakhulu okanye zibe zincinci kakhulu, ngaloo ndlela kubangele ukuphakama okungadingekile kwezibonda okanye ukwandisa inani leepali. kunye nezinye izinto ezingekho ngqiqweni.
⑷Inqaku lekona kufuneka libe liphantsi kangangoko.Ipoli ethe tye okanye indawo apho bekucetywe ukufakelwa inqaba ye-tensile ekuqaleni ayinakusetyenziswa.Oko kukuthi, ukhetho lwekona kufuneka luqwalaselwe ngokubambisana nobude becandelo le-tensile kangangoko kunokwenzeka.
⑸Ukukhetha umzila weentaba, kuyimfuneko ukuphepha ukumisa imigca kwiindawo ezimbi zejoloji kunye nemigodi yomlambo eyomileyo phakathi kweentaba, kwaye ubeke ingqalelo kwindawo yeentaba zemibhobho yamanzi kunye neengxaki zokuhamba.
Ingqalelo kufuneka ihlawulwe ekukhethweni kwendlela yendawo yokunqumla:
⑴Zama ukukhetha indawo apho umlambo uncinci, umgama phakathi kweebhanki ezimbini mfutshane, umbhede womlambo ulungile, umlambo womlambo uzinzile, kwaye iibhanki ezimbini azikhukula kangangoko kunokwenzeka.
(2)Kufuneka kuqwalaselwe iimeko zejoloji yenqaba: akukho sikhukuliseko sibi somlambo, akukho sitramu sibuthathaka, kunye nobunzulu bamanzi aphantsi komhlaba.
⑶Musa ukuwela umlambo kwindawo yokumisa isikhephe kunye nendawo yokumisa isikhephe, kwaye uphephe ukuwela umlambo amaxesha amaninzi ukuze wenze imigca.
