Hard Drawn Bare Copper Conductor

Cov tooj liab liab liab xaim xaim tooj liab ntawm ntau yam tshwj xeeb kos los ntawm cov tooj liab ntshiab. Qhov saum npoo tsis yog coated nrog tej yam conductive lossis insulating cov ntaub ntawv xws li coatings. Nws yog tooj liab hauv xim.

Tooj liab yog ib qho kev hloov pauv nrog tus lej atomic 29 thiab cov cim tshuaj Cu. [1] Ntshiab tooj liab yog cov hlau mos, qhov chaw yog xim liab-txiv kab ntxwv nrog cov xim hlau luster thaum nws tsuas yog txiav, thiab cov khoom ib leeg yog ntshav. Tooj liab muaj qhov zoo ductility, siab thermal thiab hluav taws xob conductivity, yog li nws yog cov khoom siv feem ntau siv hauv cov cables, cov khoom siv hluav taws xob thiab hluav taws xob, thiab tuaj yeem siv los ua cov khoom siv hauv tsev, thiab tuaj yeem tsim los ntawm ntau yam alloys.

Cov hlau tsis muaj tooj liab tseem tuaj yeem ua tiav rau hauv ntau yam duab raws li qhov xav tau, xws li cov xov hlau tiaj tus, cov xov hlau puag ncig thiab ntau hom xov hlau, thiab lwm yam, thiab tuaj yeem ua ke rau hauv ntau cov xov hlau uas muaj hlua khi thiab ntau txoj hlua khi los ntawm kev sib txuas ntau cov xov tooj liab liab. .

Hard drawn copper wire: Ib tus neeg xyuas pib ntawm cov tooj liab ntau tshaj 1 hli nyob rau hauv txoj kab uas hla uas ua hluav taws xob. Cov hlau tawv muaj zog tensile tsis kam (longitudinal tensile kuj), qaug zog qaug zog tsis kam (transverse fracture resistance) thiab muaj zog corrosion kuj. Cov hlau tawv tawv muaj cov nyhuv tiv thaiv tawv nqaij tsis zoo. Yog li, nrog rau tib qhov chaw hla ntu, cov xov hlau mos muaj peev xwm hla tau ntau dua tam sim no, uas yog, ua hluav taws xob ntau dua. Lub nruj "zoo" ntawm cov tawv tooj liab hlau kuj muaj nws qhov zoo: nws yooj yim dua los tuav ib daim ntawv ruaj khov, tsis zoo li cov mos tooj liab hlau uas yooj yim entangled, thiab nws yooj yim dua los npaj cov hlau, thiaj li hais lus zoo rau "tus qaib" zes" uas zoo li ib tug "mess".

Tooj liab liab hlau muaj hluav taws xob zoo conductivity thiab lub cev thiab txhua yam khoom.

Cov hlau tsis muaj tooj liab tuaj yeem ua tiav thiab muab tso rau hauv ntau hom cables, uas tau siv dav hauv cables, ultra-high voltage cables, kev sib txuas lus cables, marine cables, automotive wires, photovoltaics, electronics, electromechanical thiab lwm yam.

Lub cev muaj zog tooj liab yog fuchsia hlau nrog qhov ceev ntawm 8.92 g / cm3. Lub melting point yog 1083.4 ±{15}}.2 degree thiab lub boiling point yog 2567 degree. Nws muaj ductility zoo. Zoo thermal thiab hluav taws xob conductivity.

Cov tooj liab liab liab yuav tsum tau tsim thiab tshuaj xyuas raws li cov qauv ntawm GB / T 3953 "Electrical Round Copper Wire" thiab GB / T 4909 "Test Methods for Bare Wires".

Tom qab cov hlau liab liab qab tau tsim, nws yuav tsum tau ntim, khaws cia, tuav thiab thauj mus rau hauv nruj raws li cov neeg siv khoom thiab cov qauv kev lag luam kom ntseeg tau tias cov khoom tsis muaj dej noo thiab puas.
