I-YJV22 0.6/1KV 10-400mm² 2-5 core I-voltage ephakathi nendawo ene-armored ehlanzekile yethusi exhumene nentambo yamandla

I-YJV22 0.6/1KV 10-400mm² 2-5 core I-voltage ephansi nemaphakathi ene-armored ikhebula lamandla lethusi elihlanzekile elixhumene nesiphambano Isithombe Esifakiwe

Incazelo Yomkhiqizo

Ikhebula lamandla eligqunywe nge-PVC elivalekile, Izintambo zisetshenziselwa ukudluliswa kwamandla kanye nezinhlelo zokusabalalisa ezinama-voltage akalwe angu-0.6/1, 1.8/3, 3.6/6, 6/10, 8.7/10, 8.7/15, 12/20, 21/ 35, 26/35KV.
1. I-XLPE evalekile, izintambo zamandla e-PVC sheathed (YJV, YJLV) zilungele ngaphakathi endlini, imigudu, amapayipi, futhi zigqitshwe enhlabathini (azikho ngaphansi kwamandla emishini)
2. XLPE insulated, steel tape armored PVC sheathed power cables (YJV22, YJLV22) afanelekela endlini, umhubhe, ukungena kwamapayipi, futhi agqitshwe enhlabathini.
3. I-XLPE evalekile, izintambo zamandla ezivikelwe ngensimbi ye-PVC (YJV32, 42, YJLV32, 42) zilungele imiphini, amanzi, izindawo ezinothonsi, futhi zingamelana namandla angaphandle)

Imiyalo Yokusetshenziswa Komkhiqizo

A) ngesikhathi sokusebenza okuvamile kwekhebula, izinga lokushisa eliphezulu le-conductor lizoba ngu-70 ℃ lokufakwa kwe-PVC kanye no-90 ℃ lokufakwa kwe-XLPE.
B) Izinga lokushisa eliphezulu le-conductor phakathi ne-short circuit (isikhathi esiphezulu esingadluli amasekhondi angu-5) :
Ukufakwa kwe-PVC -- 160℃ ku-conductor cross section ≤300mm2, 140℃ ye-conductor cross section> 300mm2;Ukufakwa kwe-PVC okuhlanganisiwe ku-250 ℃.
C) Uma ubeka izintambo, izinga lokushisa le-ambient akumele libe ngaphansi kuka-0℃, futhi irediyasi yokugoba encane evumelekile ingokulandelayo:
Ikhebula eliwumgogodla owodwa: i-20D engahlomile, i-armored 15D
Ikhebula le-Multi-core: 15D nge-armored, i-12D ye-armored
Kuphi: D- ubukhulu bangempela bangaphandle bekhebula.
D) Amandla okuphuka kwekhebula:
Intambo ye-Aluminium core: 40×S (N)
Ikhebula eliwumgogodla wethusi: 70×S (N)
Qaphela: I-S iyisamba sendawo ephambanayo yekhondakta

Izici zesakhiwo somkhiqizo

1. Inokumelana okuhle kokushisa okuphezulu: Ukufakwa kwe-XLPE kusebenzisa izindlela zamakhemikhali noma ezibonakalayo ukuze kuguqulwe ukwakheka kwama-molecule e-polyethylene abe isakhiwo senethiwekhi esinezinhlangothi ezintathu.Isakhiwo senethiwekhi enezinhlangothi ezintathu sinokumelana nokushisa okuhle futhi singasetshenziswa emsebenzini Wesikhathi eside ekushiseni okuphezulu kwama-degrees Celsius angama-90, ubude bempilo bungaba iminyaka engama-40.
2. Inokusebenza okuhle kokufakwa kwe-insulation: ukusebenza kwe-polyethylene akugcini nje kuphela ukugcina ukusebenza kwe-insulation ye-polyethylene exhunywe esiphambanweni, kodwa futhi kunokuthuthukiswa okuqhubekayo kokumelana nokushisa.
3. Izici eziphezulu zemishini: ubulukhuni, ukuqina, ukumelana nokugqoka kanye nokumelana nomthelela kuye kwathuthukiswa
4. Ukumelana namakhemikhali: I-XLPE ngokwayo ine-asidi eqinile ne-alkali ukumelana nokumelana nowoyela
5. Ukuvikelwa kwemvelo: Njengoba imikhiqizo yokushiswa kwe-polyethylene exhunywe ngokuphambana ingamanzi ne-carbon dioxide, ukungcoliswa kwemvelo kuphansi, futhi kuhlangabezana nezidingo zokuphepha emlilweni.
6. Izinga lokushisa eliphezulu elilinganiselwe le-conductor yekhebula ngu-90 ° C, futhi izinga lokushisa eliphezulu le-conductor yekhebula ngesikhathi sokujikeleza okufushane (ubude besikhathi eside abudluli ku-5S) abudluli ku-250 ° C.
