The Voltage Rating Coaxial Ground Cable

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.

Oke ojiji

A na-emepụta eriri ndị dị elu dị ka otu-loop si dị, uzo abuo, ma ọ bụ ọbụna karịa loops. Ọ bụrụ na ogologo nke otu eriri ogologo, ikike a kpalitere ga-ebuwanye ibu. Ọ kacha mma ka ị ghara gafere 50v, ya bu, voltaji nke 50 volts na-enweghị nchebe ngwaọrụ. Mana ọ bụrụ na enwere ngwaọrụ nchebe, dị ka ahịrị nloghachi, eriri coaxial, wdg., ọ ekwesịghị gafere 300v.

A na-ejikarị eriri ikuku coaxial eme ihe maka waya ndu nke onye na-ejide ya na waya na-agbanye ala nke nchebe ọkụ., na igbe ala nke eriri mkpuchi mkpuchi mkpuchi mkpuchi nke eriri eriri jikọtara ọnụ. Mgbochi, eriri ala coaxial nwere njirimara impedance dị ala maka transients.

VOV (YOV YJOV) a na-ejikarị eme ihe maka njikọ njikọ nke elu-voltaji eriri iji belata ikike nke n'ọbọ ọla. Igbe nchekwa ejiri maka 110KV～220KV cross-linked cable line sheath mkpuchi ngwaọrụ ejikọrọ na igbe ntụgharị.. A na-eji ya maka njikọ ala na nnyefe na nkesa nkesa, na njikọ na cross-njikọ igbe. A na-ejikọta ndị na-eduzi n'ime na n'èzí nke eriri coaxial nke ọma na nke dị mma ma bụrụ ndị a pụrụ ịdabere na ya.
