Tam sim no, tag nrho cov ntawm lawv yog imported los ntawm txawv teb chaws, uas yog lwm "mos rib" ntawm kev lag luam.Tam sim no, qhov kev vam meej loj uas peb tau ua hauv thaj chaw ntawm

ultra-high voltage cables yog feem ntau "ua" es tsis yog "creative", vim hais tias cov ntaub ntawv tseem ceeb thiab cov khoom tseem ceeb tseem cia siab rau txawv teb chaws.

(3) Ultra-siab voltage cable thiab nws daim ntawv thov engineering

Qhov saum toj no ultra-high voltage cables thiab lawv cov ntawv thov engineering sawv cev rau qib zoo tshaj plaws hauv Suav teb high-voltage cable teb, tab sis tsis yog peb theem tag nrho.

Tag nrho cov theem ntawm lub hwj chim cable teb tsis siab, uas kuj yog ib qho tseem ceeb "cov laug cam" ntawm kev lag luam.Kuj tseem muaj ntau lwm yam "short boards" thiab

Cov kev sib txuas tsis muaj zog, xws li: kev tshawb fawb yooj yim ntawm high-voltage thiab ultra-high voltage cables thiab lawv cov tshuab, synthesis technology thiab txheej txheem cov cuab yeej ntawm super huv

resin, kev ua tau zoo stability ntawm domestic nruab nrab thiab high voltage cable cov ntaub ntawv, muaj peev xwm txhawb nqa xws li yooj yim pab kiag li lawm, Cheebtsam thiab

cov ntaub ntawv pabcuam, kev pabcuam ntev ntev ntawm cov cables, thiab lwm yam.

Cov "cov mos mos" thiab "tsis muaj zog" no yog cov teeb meem thiab teeb meem rau Tuam Tshoj los ua ib lub teb chaws muaj zog, tab sis lawv kuj yog cov kev taw qhia ntawm peb cov kev siv zog.

kov yeej obstacles thiab txuas ntxiv mus innovate.
