UJoson wenze inqubekelaphambili enkulu kubuchwepheshe bokukhiqiza be-70kN disc insulator, futhi ukuzinza kokuhlolwa kwengcindezi kwe-straight head disc insulator kungaphezu kuka-80KN

UJoson wenze inqubekelaphambili ngokushesha kwezobuchwepheshe bokukhiqiza

ukuzinza kokuhlolwa kwengcindezi kwe-straight head disc insulator (isivikelo se-cylindrical head disc) kungaphezu kuka-80KN

Ukuhlolwa kwesampula kwezimpahla ezinkulu ezithunyelwa ngaphandle

Ukuhlolwa kokusebenza kukagesi kwemikhiqizo ye-porcelain kagesi

Ukulinganisa kwe-porcelain creepage kagesi
