1. Qwalasela uphawu lwesiqinisekiso. Iimveliso ezifumene isiqinisekiso esisisinyanzelo ziya kumakishwa ngophawu lwesatifikethi, oluzezi “CCC” uphawu, kungenjalo, ziya kuthathwa njengeemveliso ezingenalayisenisi.
2. Jonga ingxelo yohlolo.Iingcingo kunye neentambo, njengeemveliso ezichaphazela ukhuseleko lobomi boluntu kunye nepropathi, zidweliswe njengogxininiso lolawulo kunye nokuhlolwa kukarhulumente. Ngoko ke, umthengisi kufuneka abe nako ukubonelela ngengxelo yokuhlolwa kwesebe lolawulo lomgangatho, kungenjalo, umgangatho wecandelo imveliso ukungabikho kwesiseko.
3. Ukugqunywa kovavanyo kunye ne-sheath.I-Insulation kunye nobukhulu be-sheath kufuneka bufane ngaphandle kokutenxa, ukuziva kufuneka kubonakale ukuxinezeleka kunye nobude.Kwangaxeshanye, isigqubuthelo kunye ne-sheath surface kufuneka ibe negama lomenzi, imodeli yemveliso eqhubekayo yokushicilela uphawu, uphawu lwekhefu: ukugquma akukho ngaphezu kwe-200mm, i-sheath engekho ngaphezu kwe-500mm.
4. Qaphela ukugqiba umzimba wekhebula kunye nombala.I-conductor yobhedu yocingo kunye nekhebula ifakwe okanye i-non-plated i-annealed annealed wire, ngelixa i-aluminium conductor iyi-aluminium okanye i-aluminium alloy wire kunye ne-smooth surface.Umqhubi wobhedu unombala omfusa okhanyayo, ngelixa umqhubi we-aluminiyam uyisilivere-mhlophe.
5. Ukulinganisa ukuxhathisa kwe-DC. Ukuze uqinisekise umgangatho weengcingo ezithengiweyo kunye neentambo zifanelekile, ungaqala ukusika i-3 ~ 5 yeemitha ukusuka kwiimveliso ezijoliswe kumbutho wokuhlola ukulinganisa ukuxhatshazwa kwe-DC.
6. Ukulinganisa ubude.Umgangatho wesizwe uchaza ngokucacileyo ubude bokuhanjiswa kweengcingo kunye neentambo, ubude bekhoyili buya kuba yi-100m, kwaye ubude bediski buya kuba bukhulu kune-100m.Abathengi banokulinganisa ubude bekhoyili ngokobude beleyibhile.Umgangatho umisela ukuba impazamo yobude ayiyi kuba ngaphezu kwe-0.5% yobude obupheleleyo.
