Chingwe cha All-dielectric self-supporting (ADSS) ndi mtundu wa chingwe cha fiber optical chomwe chimakhala cholimba kuti chizitha kudzithandizira pakati pa zinthu popanda kugwiritsa ntchito zitsulo zopangira magetsi.Imagwiritsidwa ntchito ndi makampani opangira magetsi ngati njira yolumikizirana, yoyikidwa m'mizere yomwe ilipo kale ndipo nthawi zambiri imagawana zinthu zomwe zimathandizidwa ndi ma conductor amagetsi.
M'dziko la matelefoni, kugwiritsa ntchitoZingwe za All-Dielectric Self-Supporting (ADSS).zatchuka kwambiri chifukwa cha kusinthasintha kwawo komanso kulimba kwawo.Komabe, kupanga ndi kupanga chingwe choyenera cha ADSS kungakhale njira yovuta komanso yovuta.
Chofunikira kwambiri Chomangamanga
Kuti mupange bwino kapangidwe ka chingwe cha ADSS, zinthu zambiri ziyenera kuganiziridwa. Kuphatikiza mphamvu zamakina, kondakitala sag, Liwiro la mphepo b ice makulidwe c kutentha d topography, Span, Voltage.
Nthawi zambiri, mukamapanga, muyenera kuganizira mafunso otsatirawa.
