Conductor Performance
Kunyangwe yakakwirira conductivity chiratidzo chakakosha cheakanaka kana akaipa conductor, zvimwe zvinhu zvinofanira kufungwawo. Silver inoita kunge conductor akanaka. Zvisinei, mutengo wayo wakakwira unoita kuti vashandisi vatendeuke kune dzimwe nzira. Silver inewo zvimwe zvayakaipira, sekushaya simba remuviri, izvo zvinodiwa pakuita kwe cable laying mupombi.
1）Copper Conductor
Kusachena mumhangura conductors kunogona kuva nemigumisiro inokuvadza. Kuchena kwemhangura inoshandiswa kune makondukita yakaiswa pa 100%. Kumwe kusvibiswa kunoderedza conductivity kuti 80%, zvakadai se phosphorus uye arsenic.
Aluminium yemagetsi conductors inodawo kusvibiswa kwakaderera uye kuchena kwe 99.5% kana pamusoro.
Kuoma
Shamhu yemhangura nealuminium tsvimbo zvinokonzeresa kuoma kwebasa mukudhirowa muwaya. Izvi zvinokonzera kuderera kuduku mu conductivity uye kuwedzera kwekuoma. Kutsika nekutsikirira kunowedzerawo kuoma kwemutyairi. Kana zvirinani conductor kubhenda kuita kunodiwa, annealed metal inofanira kushandiswa. Iyi nzira inogona kupedzwa mune imwe chete waya yekudhirowa maitiro, kana coil yese yewaya inogona kuiswa muchoto mushure mekunge conductor stranding apera, uye kutonhora muchoto kunowedzera nekufamba kwenguva.
1）Copper Conductor
ASTM B1, B2, uye B3 inovhara marudzi matatu ekuoma kwemhangura conductor: zvakaoma, semi-zvakaoma, nyoro, kana kuvharwa. Iyo yakapfava inowanzoshandiswa kune insulated conductors nekuti yakapfava uye iri nyore kushanda mumunda. Semi-yakaoma uye yakaoma tambo dzinowanzo shandiswa pamitsetse yepamusoro.
2）Aluminum Conductor
ASTM B 231 uye B400 inovhara concentric stranded uye denderedzwa Stranded Aluminium Conductors, zvichiteerana. Semi-yakaoma aluminium inowanzoshandiswa kune yakasimba uye 8000 Series aluminium alloy conductors nekuti aya makondakita anoda kuchinjika kukuru. 3 / 4 kuomarara uye ese akaomarara aruminiyamu conductor anogara achishandiswa kune akasungwa tambo.
Zvinhu zviviri zvinofanira kufungwa nezvazvo tisati tasarudza kuti ndeupi unhu hwemuitisi wekusarudza:
1. Conductor annealing inoda kuwedzera kwesimba uye mutengo wemidziyo.
2. Kunyangwe kune maconductor akapfava kwazvo, kuoma kwese kuchawedzera mushure mekuvhara.
Overhead conductor uye tambo dzinogara dzichidhonzwa kureba hukuru. Kuoma kwepamusoro kwemakondakita kunofanirwa kushandiswa kuwedzera simba rekusimba remakondakita. Semuyenzaniso, high tensile simba rinogona kudiwa kune conduit cables, tambo dzakaboora zvakanaka, uye maconductors makuru echikamu akaiswa pamusoro pemadaro marefu.
