XLPE intambo egqunyiweyo

I-XLPE i-insulated cable luhlobo lwentambo efanelekileyo kuthungelwano lokuhambisa kunye nezinye iindawo, ezineenzuzo ezingenakuqhathaniswa ze-PVC ze-insulated cable.Inesakhiwo esilula, ubunzima obulula, ukumelana nokushisa okulungileyo, umthamo oqinileyo womthwalo, ukunganyibiliki, ukuxhathisa ukubola kweekhemikhali kunye namandla aphezulu omatshini.

Iimbonakalo

1. Ukumelana nobushushu: I-XLPE ene-net-efana ne-three-dimensional structure inokumelana nobushushu obugqwesileyo.Ayiyi kubola kwaye i-carbonize ngaphantsi kwe-300 ° C, ukushisa kwexesha elide lokusebenza kunokufikelela kwi-90 ° C, kwaye ubomi be-thermal bunokufikelela kwiminyaka engama-40.

2. Ukusebenza kwe-Insulation: I-XLPE igcina iimpawu zokuqala zokugquma i-PE, kwaye ukuchasana kwe-insulation kuyanda.I-tangent yayo yokulahleka kwe-dielectric incinci kakhulu kwaye ayichaphazeli kakhulu ukushisa.

3. Iimpawu zoomatshini: Ngenxa yokusekwa kweebhondi ezintsha zeekhemikhali phakathi kwama-macromolecules, ukuqina, ukuqina, ukunyanzeliswa kokugqoka kunye nokuchasana kwempembelelo ye-XLPE zonke ziphuculwe, ngaloo ndlela zenza ukusilela kwe-PE ezithintekayo kuxinzelelo lwendalo kunye nokuqhekeka.

4. Ukumelana nemichiza: I-XLPE ine-asidi eqinile kunye nokuxhathisa kwe-alkali kunye nokuxhathisa kweoli, kwaye iimveliso zayo zokutsha zingamanzi kunye nekhabhoni dioksidi, engenabungozi kakhulu kwindalo kwaye ihlangabezana neemfuno zokhuseleko lomlilo lwanamhlanje.

I-110kV XLPE intambo yamandla egqunyiweyo ibonakalisa ukuzuzwa okuninzi kolwakhiwo lokukhanya, ukuqina okuphezulu okuphakathi, ilahleko ephantsi, ihlala ixesha elide ekwaluphaleni, kulula ukuyifakela, ukubeka ngaphandle komda wokuwa njl. I-110kV XLPE intambo yombane egqunyiweyo ingasetyenziswa kuthungelwano lwamandla ombane aphezulu kunye neentambo zokuhambisa. ngakumbi.Ukusetyenziswa kolu hlobo lwentambo kumasipala ongaphantsi komhlaba otshintshayo kunye neentambo zothutho ziyenyuka.
