Pay Attention Before Install Low-voltage Cables
Mgbe ị na-etinye eriri obere voltaji, hụ na ọdịdị nke eriri obere voltaji zuru ezu.
If the outer insulation layer of the low-voltage cable has noticeable stains, ọ kwesịrị ịdị ọcha tupu echichi. Ọ bụrụ na oyi akwa mkpuchi mpụta nke eriri obere voltaji nwere ntụpọ doro anya ma ọ bụ ncha dị njọ, you should avoid taking materials from this section of the cable to prevent accidents.
In installing low-voltage cables, it is necessary to ensure that the installation of eriri obere voltaji conforms to safety regulations. Ndị na-arụ ọrụ kwesịrị iji ngwaọrụ pụrụ iche ma wụnye eriri obere voltaji dịka usoro ọrụ ziri ezi si dị.
Ụzọ isi wụnye eriri ọkụ ọkụ dị ala
Mgbe ị na-akpachapụ eri ahụ, ekwesịrị idobe oke maka mfu nhazi. Ma ọ bụ nnọọ amachibidoro imebi oyi akwa mkpuchi, mkpuchi oyi akwa, core conductor, and cable sheath of the parts that do not need to be treated. Ọzọkwa, A machibidoro iwu nke ọma iji aka efu emekọrịta ihe n'oge echichi. Na onye na-eduzi ndị a gbapụrụ agbapụ kwesịrị ịgwọ n'oge iji gbochie elu nke onye nduzi.
Mgbe etinyere eriri obere voltaji, you must use a testing tool to detect whether the wire and cable are well-connected to cable equipment. Nlebara anya pụrụ iche kwesịrị ịṅa ntị na ebe enwere nsonaazụ nkwụsị. Check whether the insulating tape paste prevents water leakage and electricity leakage well.
Na mgbakwunye na ụzọ abụọ ziri ezi n'elu, eriri obere voltaji kwesịkwara ịwụnye dịka ọnọdụ gburugburu ebe obibi si dị. It should prohibit installing low-voltage cables at a high temperature. Na iji gbochie eriri ahụ ka ọ ghara imebi ya nke ọma.
