Kondisyon debaz pou aparans nan pwodwi fil ak kab

(1) wonn baton aliminyòm

Li oblije tcheke degre nan wonn, si gen domaj tankou pli, misrounds, fant, enklizyon, kinks, ak grav domaj mekanik mak, twou, penti kap dekale, flache, tach korozyon, elatriye.

(2) Fil kwiv wonn

  Check whether the surface is smooth and clean, whether there are triangular mouths, burrs, cracks, folds and inclusions and serious scars, pits, corrosion spots of mechanical damage, etc. It is worth mentioning that there is also the degree of oxidation of the copper wire. Generally, golden yellow is normal, light red is slightly oxidized, and the surface is dark red and blue, which is serious oxidation. Any serious oxidation should be judged as waste disposal. There are many cases of aluminum wire in the manufacturing process, and it should be strictly controlled when making overhead transmission lines.

(3) Sifas liy aliminyòm

  The wires of wire and cable products should be twisted tightly and neatly, and there should be no looseness, kinking of single wires, jumping out or bulging of single wires and breaking of single wires.

Anplis de sa, pati nan soude nan yon sèl -joint fil la ta dwe awondi ak soude a te mande tretman anti-korozyon. Anjeneral, pati elaji jwenti a pa ta dwe depase de fwa tolerans dyamèt la. Kote a soude pa ta dwe mwens pase 15 mèt, distans ki genyen ant de kote yo soude nan menm kouch la se pa menm fil sèl la, kouch enteryè a pa ta dwe mwens pase 5 mèt, ak kouch ekstèn lan pa ta dwe mwens pase 15. mèt. Lè nwayo a kòb kwiv mete se yon sèl fil kwiv, soude pa pèmèt.
