I-20000 ye-disc insulators kunye ne-25000 yokuchasana nokungcoliseka (i-double-shed) I-Porcelain Suspension Insualtors ethunyelwa kuMntla Melika ikwimveliso.

Ngoku umzi-mveliso uvelisa i-disc insulators kunye ne-Anti-pollution (i-double-shed) insulators, kwaye umjikelezo wemveliso malunga nenyanga enye.

Lungiselela amanzi e-glaze

linganisa umlinganiselo wemathiriyeli ekrwada ngomlinganiselo we-elektroniki ngokweemfuno zenkqubo, xuba izinto ezikrwada, emva koko uxube izinto ezikrwada ngokulinganayo ukuqinisekisa ukucoleka kunye nokuhlelwa kwamasuntswana eludaka.
