High voltage cables uye low voltage cables ane akasiyana masisitimu akasiyana, achikanganisa kuita kwavo uye mashandisiro. Iko kuumbwa kwemukati kwetambo idzi kunoratidza kusiyanisa kwakakosha:
High Voltage Cable Structure:
1. Muitisi
2. Inner Semiconducting Layer
3. Insulation Layer
4. Outer Semiconducting Layer
5. Metal Armor
6. Sheath Layer
Low Voltage Cable Structure:
1. Muitisi
2. Insulation Layer
3. Steel Tape (Haisipo mumatambo akawanda emagetsi mashoma)
4. Sheath Layer
Iyo yekutanga kusiyana pakati peyakakwira voltage uye yakaderera tambo tambo dziri pamberi peiyo semiconducting layer uye inodzivirira layer mumatambo akakwira voltage. Nekuda kweizvozvo, tambo dzemagetsi akakwira anowanzo kuve neakanyanya kukora ekuisa zvigadziko, zvichikonzera chimiro chakaoma uye chinoda maitiro ekugadzira.
Semiconducting Layer:
Iyo yemukati semiconducting layer inoshanda kuvandudza magetsi emunda maitiro. Mumatambo emagetsi akakwira, padyo pakati pe conductor uye insulation layer inogona kugadzira mapundu, zvichitungamira kune chikamu chinobuda chinokuvadza insulation. Kuti uderedze izvi, semiconducting layer inoita seshanduko pakati pesimbi conductor uye insulation layer. Saizvozvo, iyo yekunze semiconducting layer inodzivirira kubuda kwenzvimbo pakati peiyo insulation layer uye simbi sheath.
Shielding Layer:
Iyo simbi inodzivirira layer mune yakakwira voltage tambo inoshandisa zvitatu zvikuru zvinangwa:
1. Electric Field Shielding: Inodzivirira kupindira kwekunze nekudzivirira nzvimbo yemagetsi inogadzirwa mukati meiyo high voltage cable.
2. Kufambisa kweCapacitive Current panguva yeKushanda: Inoita senzira ye capacitive current flow panguva yekushanda kwetambo.
.
Kusiyanisa Pakati peHigh Voltage uye Low Voltage Cables:
1. Structural Examination: High voltage cables dzine mamwe ma layers, zvinoonekwa pakupenengura denga rekunze kuratidza simbi yezvombo, nhovo, insulation, uye conductor. Kusiyana neizvi, tambo dzakaderera-voltage dzinowanzofumura insulation kana maconductor pakubviswa kweyekunze layer.
2. Insulation Ukobvu: High voltage cable insulation yakanyanya kukora, kazhinji inodarika 5 millimeters, nepo low voltage cable insulation iri mukati memamirimita matatu.
3. Cable Markings: Iyo yekunze tambo yetambo kazhinji ine mamaki anotsanangura tambo mhando, mhiri-chikamu nzvimbo, yakayerwa voltage, kureba, uye mamwe maparamita akakodzera.
Kunzwisisa izvi zvimiro uye mashandiro akasiyana kwakakosha pakusarudza tambo yakakodzera kune chaiyo maapplication, kuve nechokwadi chekuita kwakakwana uye kuchengeteka.
