Ọkwa voltaji nke coaxial grounding cable kwesịrị kpebisie ike dị ka mkpali ike nke eriri eriri. Dị ka ahụmahụ imewe gara aga, larịị voltaji nke coaxial grounding cable bụ n'ozuzu 10kV; A ga-ahọrọ nke ọma nke akụkụ obe nke coaxial grounding cable dị ka ala nke ugbu a nke eriri eriri.. Agbanyeghị, n'ezie ọrụ, n'ihi enweghị data na mgbagwoju anya nke ngụkọta oge. Ụdị isi bụ VOV, YJOV, na YOY.
