Chingwe cha Mphamvu cha IEC/BS Standard 12.7-22kV-XLPE Chotetezedwa ndi Voltage yapakati ya MV

Mafotokozedwe:

    Yoyenera maukonde amagetsi monga malo opangira magetsi. Yoyikira m'mapaipi, pansi pa nthaka komanso panja.

    Zingwe zopangidwa ndi BS6622 ndi BS7835 nthawi zambiri zimakhala ndi ma conductor a Copper okhala ndi zingwe zolimba za Class 2. Zingwe za single core zimakhala ndi aluminiyamu wire armour (AWA) kuti zisawononge mphamvu yamagetsi mu armour, pomwe zingwe za multicore zimakhala ndi zitsulo zachitsulo (SWA) zomwe zimateteza makina. Izi ndi zingwe zozungulira zomwe zimapereka kuphimba kopitilira 90%.

    Dziwani: Chigoba chofiira chakunja chikhoza kutha msanga chikakhudzidwa ndi kuwala kwa UV.
