Electric wires maka esịtidem wiring: Chọrọ

Nwụnye nke eletriki nkwurịta okwu n'ime ogige dị oké mkpa. Electric wires maka esịtidem wiring ike nke na-enye ezigbo àgwà nke ike. The usoro ga-arụrụ niile na ọrụ e kenyere ya na zuru, nakwa dị ka ime na eletriki na ọkụ nchekwa.

Ịzụlite usoro, ọ dị mkpa ka ntị ka ihe onwunwe na imewe nke eletriki wires maka esịtidem wiring, nakwa dị ka ha ụdị na cross-ngalaba.

Types of ebikwasị wires

E nwere atọ nhọrọ maka wụnye wiring n'ime ụlọ: oghe, jikọtara na-ezo.

Open wiring dị mfe iji wụnye, ọ dịghị achọ ka nkwadebe nke mines maka nkwukọrịta. Ya bụ isi emezi bụ kara n'etiti chọrọ nke eletriki nchekwa. Na izugbe nke a, ndị ihe echichi bụ nnọọ unsightly. Ya mere, na a residential ebe otú nwụnye bụ na ojiji.

Jikọtara usoro na-agụnye a elektrosoobscheny pụrụ iche igbe. Dị otú ahụ echichi na-adịghị achọ na-ebikwasị mines n'ime mgbidi, ma ọkụ eletrik mgbe na-ezo na pụrụ iche plastic ọwa. View nke usoro bụ nnọọ aesthetic na nchekwa chọrọ na-zutere na zuru.

The kasị nkịtị na-zoro ezo wiring, nke na-positioned n'ime plaster. Ya drawback bụ kama mgbagwoju anya usoro maka emelite usoro.

ihe-eduzi

Akwara electric wires maka esịtidem wiring, dị ka nchekwa chọrọ, ọ nwere ike mere nke ọla kọpa ma ọ bụ aluminum. N'ọnọdụ ka ukwuu nke abụọ nhọrọ na-eji.

N'okpuru yiri ugbu ibu ngalaba aluminum wires ga-adị ukwuu karịa nke ọla kọpa. Ntụkwasị obi nke a na ihe onwunwe ogige nwekwara ala. Nke a bụ n'ihi na ndị dị otú ahụ aluminum Njirimara ka flowability na ọxịdashọn.

Ọla kọpa wires jikọọ site na njikọ na-agbagọkwa na soldering. A ihe onwunwe bụ obere susceptible ka corrosion na nwere nnukwu conductivity na ike.
