Ingcaciso yeMveliso

Intambo yamandla edityanisiweyo ye-polyethylene edityanisiweyo ayinayo kuphela umbane ogqwesileyo, iipropathi zoomatshini, kodwa inokumelana okunamandla ngokuchasene nokubola kweekhemikhali, ukuguga kobushushu kunye noxinzelelo lokusingqongileyo.Isakhiwo sayo silula.Ubushushu bokusebenza bexesha elide yi-90ºC. Ilungele ukusetyenziswa kwaye inokubekwa ngaphandle kwesithintelo somgangatho owahlukileyo.
Libazise ukusasazeka kwedangatye ecaleni kwentambo ukuze umlilo ungandi.Ngenxa yexabiso layo eliphantsi, isetyenziswa kakhulu kwiintambo ezingatshiyo.Ngaphantsi kweemeko zentambo enye okanye i-bundle yokubeka, ukusasazeka komlilo kunokulawulwa ngaphakathi kwinqanaba elithile xa intambo ivutha, ngoko ke iintlekele ezinkulu ezibangelwa ngumlilo zinokuphetshwa, ukwenzela ukuba kuphuculwe inqanaba lokuthintela umlilo kwintambo yentambo. .

Imiyalelo yeMveliso yokusetyenziswa

A) ngexesha lokusebenza okuqhelekileyo kwentambo, ubushushu obuphezulu be-conductor iya kuba yi-70 ℃ ye-PVC yokugquma kunye ne-90 ℃ ye-XLPE yokugquma.
B) Elona qondo liphezulu lobushushu be-conductor ngexesha lesekethe emfutshane (ubude bexesha elide elingadlulanga kwimizuzwana emi-5):
Ukufakwa kwe-PVC -- 160 ℃ yecandelo le-conductor cross ≤300mm2, i-140 ℃ yecandelo lomnqamlezo lomqhubi> 300mm2;Ukugquma kwePVC kwi-Crosslinked kwi-250 ℃.
C) Xa ubeka iintambo, ubushushu be-ambient abuyi kuba ngaphantsi kwe-0℃, kwaye ubuncinci obuvumelekileyo berediyasi yokugoba bunjengoku kulandelayo:
Intambo engundoqo enye: i-20D engenasikrweqe, i-15D exhobileyo
Multi-core cable: 15D for unarmored, 12D for armored
Kuphi: D- idiameter yangempela yangaphandle yentambo.
D) Amandla okuqhawuka kwentambo:
Intambo ye-aluminiyam engundoqo: 40×S (N)
Intambo engundoqo yobhedu: 70×S (N)
Qaphela: I-S yindawo epheleleyo enqamlezileyo yomqhubi

Iimpawu zesakhiwo semveliso

1, Intambo isekelwe kwi-IEC 60502-1 kunye ne-GB standard.
2, 20 ºC umqhubi we-DC resistivity: undoqo wobhedu ≤ 0.017241Ωmm2/mo core aluminiyam ≤ 0.028Ωmm2/m.
I-3, i-flame retardant grade A, B, C, D, i-WDZ ephantsi yomsi we-halogen-free, uhlobo oluchasene nomlilo NH, lunokwenziwa ngokwezifiso ze-ZA-YJV, ZB-YJV, ZC-YJV (ZR-YJV), WDZ-YJV, I-N-YJV (NH-YJV).
4.Elona qondo lobushushu liphezulu lokusebenza kwintambo yeyjv yi-90ºC.
5, intambo kufuneka ibekwe kwiqondo lobushushu elingekho ngaphantsi kwe-0 ºC, irediyasi yokugoba efakwe ikhebula kufuneka ibe nkulu kunamaxesha angama-20 ubukhulu bangaphandle bentambo.<5PC.
4, Ubushushu bokubeka kufuneka bungabi ngaphantsi kwe-0ºC.
5. Kwimeko yesekethe emfutshane, ubushushu obuphezulu bomqhubi kufuneka bungabi ngaphezu kwe-160ºC ixesha elingekho ngaphezu kwemizuzwana emi-5.
I-6.YJV YJLV ifanelekile ukubekwa kwangaphakathi nangaphandle, kodwa ayikwazi ukuthwala isenzo samandla angaphandle omatshini.yjv22, yjlv22 zilungele ukungcwatywa kokubekwa, zinokuthwala isenzo samandla omatshini angaphandle, kodwa azikwazi ukuthwala amandla amakhulu.
