Zeziphi iintambo ezisetyenziswa kwiinqanawa kunye namaqonga angaphesheya kolwandle?Oku kulandelayo sintshayelelo kwiindidi zeentambo zombane ezisetyenziswa kwiinqanawa kunye namaqonga angaphesheya kolwandle.
1. Injongo:
Olu hlobo lwentambo lufanelekile ukuhanjiswa kwamandla kwiinkqubo zamandla kunye ne-AC ye-voltage ye-0.6 / 1KV nangaphantsi kwimilambo eyahlukeneyo kunye neenqanawa zolwandle, i-oyile ye-offshore kunye nezinye izakhiwo zamanzi.
2. Umgangatho weReferensi:
IEC60092-353 1KV～3KV kunye neentambo zombane zamandla zaselwandle ezingaphezulu
3. Sebenzisa iimpawu:
Ubushushu bokusebenza: 90℃, 125℃, njl.
Umbane olinganisiweyo we-U0/U: 0.6/1KV
Ubuncinci berediyasi yokugoba: hayi ngaphantsi kwamaxesha ama-6 ubukhulu bangaphandle bentambo
Ubomi benkonzo yentambo ayikho ngaphantsi kweminyaka engama-25.
4. Iimpawu zokusebenza:
Ukuchasana kwe-DC komqhubi kwi-20 ° C idibana nomgangatho we-IEC60228 (GB3956).
Ukuxhatshazwa kwe-insulation ye-cable kwi-20 ° C ayikho ngaphantsi kwe-5000MΩ·km (iphezulu kakhulu kunesalathisi sokusebenza kwe-insulation resistance resistance efunekayo yi-IEC60092-353 standard).
Ukusebenza kwe-flame retardant ihlangabezana neemfuno ze-IEC60332-3-22 i-Class A flame retardant (umlilo wemizuzu engama-40, kwaye ukuphakama kwe-carbonization yekhebula akudluli kwi-2.5m).
Kwiintambo ezikwazi ukumelana nomlilo, ukusebenza kwazo kokumelana nomlilo kuhlangana ne-IEC60331 (imizuzu engama-90 (unikezelo lomlilo) + imizuzu eyi-15 (emva kokususwa komlilo), ubushushu bomlilo 750 ℃ (0 ~ +50 ℃) unikezelo lwamandla ombane luqhelekileyo, akukho mbane).
Isalathisi esisezantsi se-halogen-free index ye-cable ihlangabezana neemfuno ze-IEC60754.2, ukukhutshwa kwegesi ye-halogen ye-halogen ayikho ngaphezu kwe-5mg / g, ukufumanisa okucacileyo kwexabiso layo le-pH ayikho ngaphantsi kwe-4.3, kwaye i-conductivity ayikho. ngaphezu kwe-10μs/mm.
Ukusebenza komsi ophantsi wentambo: Ubuninzi bomsi (ukuhanjiswa kokukhanya) kwentambo ayikho ngaphantsi kwama-60%.Zifezekise iimfuno ezisemgangathweni ze-IEC61034.
5. Ubume bekhebula
I-conductor yenziwe ngekopolo etotiweyo ekwizinga eliphezulu.Olu hlobo lomqhubi lunempembelelo entle kakhulu yokuchasana nomhlwa.Isakhiwo somqhubi sahlulwe saba ngabaqhubi abaqinileyo, abaqhubi abadibeneyo kunye nabaqhubi abathambileyo.
I-insulation ithatha i-insulation extruded.Le ndlela ye-extrusion inokunciphisa igesi phakathi kwe-conductor kunye ne-insulation ukukhusela ukungena kokungcola okufana nomphunga wamanzi.
Ikhowudi yombala ngokubanzi iyahlukaniswa ngombala.Imibala ingakhethwa kwaye iqhutywe ngokweemfuno zesayithi ukuze kube lula ukufakwa.
I-sheath yangaphakathi / i-liner (I-Jacket) yimpahla ephantsi ye-halogen engenamsi kunye ne-flame retardancy ephezulu.Izinto eziphathekayo zi-halogen simahla.
Umaleko wesikrweqe (Isikrweqe) luhlobo oluphothiweyo.Olu hlobo lwesikrweqe lunokuguquguquka okungcono kwaye lulungele ukubeka intambo.Izixhobo ezilukiweyo zesikrweqe ziquka ucingo lwekopolo olunkonkxiweyo kunye nocingo lwentsimbi oluyinkuni, zombini zinempembelelo entle yokuchasa ukudumba.
I-sheath yangaphandle (i-Sheath) imathiriyeli nayo i-halogen engenamsi ophantsi.Oku akuvelisi gesi inetyhefu xa kutsha kwaye kuvelisa umsi omncinci.Isetyenziswa ngakumbi kwiindawo ezixineneyo.
Ukuchongwa kwentambo kunokuprintwa ngokweemfuno zangempela.
6. Imodeli yentambo:
1. Imodeli yentambo yentambo ye-halogen engenamsi ophantsi we-XLPE yangaphandle:
CJEW/SC, CJEW/NC, CJEW95(85)/SC, CJEW95(85)/NC,
2. Imodeli yentambo yentambo ye-halogen engenamsi ophantsi we-EPR igqunywe ngaphandle:
CEEW/SC, CEEW/NC, CEEW95(85)/SC, CEEW95(85)/NC,
3. Inkcazo yomzekelo:
C- ithetha intambo yamandla olwandle
Ukufakwa kwe-J-XLPE
I-E-EPR (i-Ethylene Propylene Rubber Insulation)
EW-low umsi halogen free polyolefin sheath
95- Isikrweqe esilukiweyo socingo lwentsimbi kunye ne-LSZH isingxobo sangaphandle (i-braid density ayikho ngaphantsi kwama-84%)
85-Isikrweqe esilukiweyo socingo olunkonkxiweyo kunye ne-LSZH isingxobo sangaphandle (ubunzima bebraid bungekho ngaphantsi kwama-84%)
Ukusebenza kwe-flame retardant ye-SC-cable idibana ne-IEC60332-3-22 i-Class A retardant flame, kwaye umxholo we-halogen ungaphantsi kwe-5mg / g
I-NC - Ukumelana nomlilo kwentambo idibana ne-IEC60331, kwaye umxholo we-halogen ungaphantsi kwe-5mg / g
