Mfundo Zaukadaulo ndi Kukhathamiritsa Kwazotayika
Magwero Otayika
Makamaka zimaphatikizapo kutayika kotsutsa (kutayika kwa kutentha komwe kumabwera chifukwa cha kuyenderera kwa kondakita) ndi kutayika kwa dielectric (polarization zotsatira za insulating material). Kutayika kokana kumawonjezeka ndi ma square root of frequency, pomwe kutayika kwa dielectric kumawonjezeka motsatira pafupipafupi.
Njira Zowonjezera
Zinthu Zoyendetsa:Gwiritsani ntchito-strand silver-waya wopukutidwa ndi copper kuti muchepetse kukhudzika kwa khungu.
Insulation:Gwiritsani ntchito polyethylene yowonjezera kapena fluoroplastic kuti muchepetse kusinthasintha kwa dielectric ndikuchepetsa kuyamwa kwa mphamvu.
Kapangidwe kachitetezo:Silver-tepi yopukutidwa yamkuwa + wapamwamba-kuluka kolimba kumapereka chitetezo chowirikiza kupondereza kusokonezedwa ndi ma elekitiroma.
Zhenjiang Tongda Electronics Co., Ltd. ndi katswiri wopanga lmr 400 coaxial chingwe, kukupatsani mankhwala oyenera inu.
