Zombini i-YJY kunye ne-YJV ziimveliso zocingo kunye neentambo eziqhelekileyo ezisetyenziswa kubunjineli kunye nolwakhiwo, kwaye zisetyenziselwa iintambo zokuhambisa amandla.Nangona kunjalo, iimodeli kunye neenkcukacha zezi zimbini zihlukile.Ngaba kukho nawuphi na umahluko kwizinto kunye nexabiso lesingxobo?Ngezantsi, umhleli uya kukwabelana nawe umahluko phakathi kwe-YJY kunye ne-YJV.
YJY Cable
Yazisa
I-YJY——Intambo yamandla egqunywe nge-polyethylene egqunywe nge-polyethylene, intambo yamandla eyenziwe nge-polyethylene ineempawu ezigqwesileyo ze-thermomechanical, ukusebenza okuphezulu kwe-flame retardant, kwaye i-ampacity ingcono kuneentambo zamandla ze-YJV eziqhelekileyo, kwaye ikwaphucula ukusebenza kwentambo.ukusebenza kombane kunye neempawu zokumelana nobushushu.
YJ——i-polyethylene edityanisiweyo
Y——ipolyethylene
Isicelo
Inokubekwa ngaphakathi, kwimibhobho okanye kumhlaba okhululekileyo, ngaphandle kokuba ayikwazi ukumelana noxinzelelo kunye noxinzelelo;inokusetyenziswa kuthungelwano losasazo okanye kufakelo lwemizi-mveliso olunomgangatho wombane we-1-1000kV nangaphezulu, njengezikhululo zombane, iintambo zokukhanyisa ezidolophini, kunye nokuhanjiswa kombane okwinqaba ephezulu, ukuhanjiswa kombane okumgangatho ophantsi kunye nezinye iindawo.
Iimbonakalo
Iintambo ze-YJY zilula kwisakhiwo, zimodareyitha ebukhuni kunye nokuthamba, kwaye zilungele ukuthuthwa, kodwa azinyanzelisi, ngoko kufuneka ziqwalaselwe xa zigcinwa okanye zithuthwa.
Inzuzo
Ngokweemfuno zabanye abasebenzisi, i-YJY Power Cable inokuvelisa iintambo ezisetyenziswe kwiimeko ezifunwa kakhulu ezifana ne-flame-retardant (ZB), i-fire-resistant (NH), kunye ne-low-smoke kunye ne-low-halogen (WDZ).Ezi ntambo zinokhuseleko oluphezulu kunye nokusebenza, kwaye zinobuhlobo nokusingqongileyo.Ukusebenza ngamandla.
Intambo yeYJV
Intambo ye-YJV ikwabizwa ngokuba yi-cross-linked polyethylene insulated PVC sheathed power cable.Phakathi kwazo, i-YJ imele ukugquma kwe-polyethylene edibeneyo, kwaye i-V imele i-polyvinyl chloride sheath.Phakathi kwabo, i-YJV iphinda imele i-copper core cable, ngelixa i-YJLV imele i-aluminium core cable.
NO.1 indlela yokubeka
1. I-YJV, i-YJLV yobhedu (i-aluminium) ingundoqo ye-XLPE efakwe kwi-sheath ye-PVC ifakwe ngaphakathi, kwimisele kunye nemibhobho, kwaye ingangcwatywa kumhlaba ovulekileyo, kodwa ayikwazi ukuthwala uxinzelelo kunye namandla omatshini angaphandle.
2. YJV22, YJLV22 ubhedu (aluminiyam) undoqo XLPE tape insulated steel tape armored PVC sheathed power cables zibekwe phantsi komhlaba kwaye zinokumelana nemikhosi yangaphandle yomatshini, kodwa ayinakumelana nemikhosi emikhulu yokuqina.
NO.2 Sebenzisa iimpawu
Ubushushu obuphezulu obulinganisiwe be-cable conductor yi-90°C.Xa i-short-circuited (ubude bexesha elide alidluli kwi-5S), ubushushu obukhulu be-cable conductor ayidluli i-250 ° C.Ubushushu be-ambient xa ubeka intambo akufunekanga ibe ngaphantsi kwe-0°C.I-radius yokugoba evumelekileyo xa ubeka: ikhebula elilodwa elingundoqo alikho ngaphantsi kwamaxesha angama-15 ububanzi obungaphandle bekhebula;i-multi-core cable ayikho ngaphantsi kwamaxesha angama-10 ububanzi bangaphandle bekhebula.
NO.3 Indlela yokukhetha
Umbane olinganisiweyo wentambo umelwe ngu-U0/U (Um): i-U0 yi-voltage elinganisiweyo yamandla ombane phakathi kwe-conductor yoyilo lwentambo kunye nomhlaba okanye isikhuselo sesinyithi, i-U yi-voltage elinganisiweyo yamandla ombane phakathi kwee-conductor zoyilo lwentambo, Um. yi Elona xabiso liphezulu lenkqubo yombane ephezulu esinokumelana nayo isixhobo.Ngokwendawo ehlukeneyo yokubeka kunye nomthwalo wekhebula, iinkcukacha kunye neemodeli zekhebula zenziwa kwaye zikhethiweyo.
Uhlobo lwe-non-armored lufanelekile kwi-overhead, ngaphakathi, i-tunnel, i-cable trench kunye nezinye izihlandlo, kwaye ayikwazi ukuthwala amandla omatshini angaphandle.Uhlobo lwe-armored lunokungcwatywa ngokuthe ngqo emhlabeni ngaphandle kweemeko ezisebenzayo zohlobo olungekho.Iyakwazi ukuthwala amandla athile omatshini angaphandle.Iintambo ezinondoqo omnye azivumelekanga ukuba zifakwe kwimibhobho eyenza imagnethi.Iintlobo ezikhethekileyo zeentambo kufuneka zikhethwe ukutsha, ukuqhuma, ukutshatyalaliswa kweekhemikhali, ukushisa okuphezulu, ukushisa okuphantsi kunye nezinye iimeko.
Umehluko
Okokuqala, i-YJY inokuxhathisa okungcono kwamanzi kunye nokumelana nobushushu obuphantsi kune-YJV, kwaye i-YJV inokunciphisa ilanga elingcono kune-YJY.Iqondo lokushisa eliphezulu elilinganisiweyo le-YJY i-cross-linked polyethylene insulated power cable conductor yi-90 ° C, ephakamileyo kuneentambo ze-polyethylene ezifakwe kwi-insulated, ngoko ke amandla okuthwala ikhebula ngoku ayanda.Iqondo lokushisa eliphezulu elilinganiselweyo lomsebenzi we-conductor ngu-90 ° C, kwaye ubuninzi be-short-circuit ye-conductor ayiyi kudlula i-250 ° C, kwaye ixesha elide aliyi kudlula imizuzwana emi-5.Intambo ye-YJV ineempawu ezibalaseleyo ze-thermomechanical, iimpawu zombane ezigqwesileyo kunye nokumelana nokubola kweekhemikhali.Kananjalo ineenzuzo zesakhiwo esilula, ubunzima obulula, kwaye akukho mqobo ekubekeni ukuphakama.Yintambo entsha okwangoku esetyenziswa ngokubanzi kwiigridi zamandla ezidolophini, imigodi kunye neefektri.
Okwesibini, i-sheath ye-YJV yi-PVC, eyintambo ene-halogen;i-sheath ye-YJY yi-polyethylene, eyintambo engena-halogen.
Ekugqibeleni, ixabiso lentambo ye-YJY liphezulu.I-YJY lubhedu oludityanisiweyo oludityanisiweyo lwepolyethylene egqunywe nge-polyethylene sheathed intambo yamandla, kunye ne-YJV lubhedu oludityanisiweyo oludityanisiweyo lwepolyethylene egqunywe nge-polyvinyl chloride intambo yamandla egqunyiweyo.Nangona kunjalo, ixabiso lezinto ze-XLPE liphezulu kunelo lezinto zePVC, ezikhokelela kwiindleko eziphezulu ze-YJY.
