1st Nov 2021, cylindrical head disc insulator yathu imatha kufikira 300kN tension load, oyenerera komanso otetezeka.

Dpoyang'anira kuwunika kwakukulu kwa zida zowongoka zoyimitsidwa za ceramic zomwe zatumizidwa posachedwa, kulimba kwazinthu zomwe zapezeka ndikufika ku 300KN.

Ndipo tsopano fakitale Technology Department ikupanga 420kN mavuto katundu chimbale insulator
