particular, ACCC conductors Tau siv los ua kom cov efficiency ntawm tus cwjpwm rov tsim feem ntawm cov transmission grid los ntawm 30% los yog ntau dua.
ACCC cables siv lightweight, Me me carbon fiber composite tub ntxhais. Nws tsub kom lub load-bearing peev xwm ntawm tag nrho cov khoom thiab txo tus tub ntxhais ntim ntawm tus tshiab ACCC cable. ACCC cables yuav muab ob npaug ntawm tsoos cables, zoo solving qhov teeb meem ntawm cable sag los ntawm kub muaj peevxwm.
Thaum aluminum strands mas annealed muab lub siab kawm ntawv ntawm hluav taws xob conductivity ntawm tej aluminum khoom muaj hnub no, Cov tub ntxhais composite khoom muaj ib coefficient ntawm thermal expansion uas yog kwv yees li ntawm 10 zaug uas hlau.
Daim Ntawv Thov Kev Pab Ntawm ACCC Conductor
ACCC aluminum conductor composite tub ntxhais yog qhov tseeb hom stranded tus cwjpwm, Feem ntau nws yog siv nyob rau hauv overhead transmission kab. Nyob rau tib yam mob, Nws muaj ob zaug lub peev xwm ntawm ACSR.
ACCC conductors feature ib hybrid carbon fiber thiab iav fiber tub ntxhais embedded nyob rau hauv ib lub kev kawm epoxy matrix. Lub hab txhawb carbon-fiber tub ntxhais consists kaum tawm txhiab tus high-strength, High-modulus unidirectional carbon fibers surrounded los ntawm ib tug tiv thaiv iav fiber txheej txheem. Tus txheej txheem ntawm fiberglass tsub kom toughness thiab yooj ywm, Thaum tseem muab ib barrier rau hluav taws xob tam sim no.
ACCC conductor hybrid tub ntxhais no tsis tsuas ob zaug li hlau tab sis 70% Ntais. Lub teeb luj pub ACCC conductors siv kwv yees li ntawm kwv yees li ntawm 28% Aluminum tsis ntxiv luj los yog diameter.
Kom zoo dua cov ACCC Conductors
Piv nrog rau tib diameter ACSR cable, Nws yuav coj ob npaug rau tam sim no nqa peev xwm. Zoo daws qhov teeb meem ntawm cable snagging. Lawv yuav ua hauj lwm ntawm kub dua qhov kub, nce 200 degrees Celsius. Thiab cov tub ntxhais yog corrosion resistant thiab muaj cov tsis muaj bi-metallic corrosion teeb meem. Vim hais tias nws yuav muab ntau dua tam sim no-nqa peev xwm thiab zoo txo engineering nqi.
Carbon fiber composite tub ntxhais tseem ceeb khoom rau polypropylene acrylic carbonized carbon fiber thiab muaj peevxwm curing resin, carbon fiber filament longitudinal neeg, Thaum lub resin yuav carbon fiber filament integrated rau hauv ib tug lej. Tib lub sijhawm, Nws muaj nws ib txheej txheem ntawm kev tiv thaiv ntawm qhov chaw ntawm lub composite tub ntxhais los tiv thaiv corrosion ntawm tus tub ntxhais composite tub ntxhais nyob rau hauv qhov chaw atmospheric, Thiab lub luag hauj lwm ntawm lwm aluminum hlau.
Carbon fiber composite tub ntxhais muaj cov cim raws li cov cim
(1) Density
Carbon fiber composite tub ntxhais density no tsuas 1/4 Ntawm tus tub ntxhais zoo tib yam
(2) Loj Tensile lub zog
Carbon fiber composite tub ntxhais tensile lub zog txog li 2400MPa, Mus zoo tib yam steel tub ntxhais lub sij hawm.
(3) Tshav kub kub kuj zoo
Carbon fiber composite tub ntxhais elongation ntawm muaj peevxwm yog me dua zoo tib yam steel tub ntxhais.
Saum toj no nta 1, Nta (2) txiav txim seb siv cov fiber composite tub ntxhais nyob rau sab hauv lub arc droop yog me dua zoo tib yam steel aluminum tso tseg hlau, Nta (3) txiav txim seb siv cov fiber composite tub ntxhais ntawm kub hauv lub arc droop kev loj hlob yog me me. Carbon fiber composite forest hlau lwm aluminum hlau yog feem ntau heat-resistant aluminum alloy hlau los yog soft aluminum hlau.
Thaum uas siv cua kub-resistant aluminum alloy hlau, muaj zog mechanical lub zog, conducive rau qhov siv ntawm lub hlau, Tab sis nws resistivity yog ib nyuag ntau dua conventional aluminum hlau, kuj tsis tau yog hais txog 5% ntau dua, Thaum uas siv soft aluminum hlau, Tus resistivity no tsis loj dua conventional aluminum hlau, Tab sis cov khoom yog softer, yooj yim rau kev puas tsuaj.
Qhov kev khiav hauj lwm kub ntawm tshav kub-resistant aluminum alloy hlau thiab soft aluminum hlau yog ntau dua uas conventional aluminum hlau, Li ntawd, tus cwjpwm yuav ua kom tus transmission peev xwm los ua qhov kev khiav hauj lwm kub.
ACCC cable tshuab pub transmission tuam txhab uas muag, tuam txhab uas muag fais fab tuam, thiab hwj huam nroj tsuag los hloov tus corresponding transmission kab tsis xav tau kev txawj ntse tshwj xeeb thiab khoom los yog modifying cable racks. Aluminum conductor steel tub ntxhais (ACSR) Thiab lwm yam transmission cables siv ib hlau hlau hlau tub ntxhais, Feem ntau raws li ib tug tsoos 1898 tsim.
