Yam Yuav Tsum Tau Paub Txog Cov Khoom Siv Hluav Taws Xob thiab Cable

(1) Round aluminium pas nrig

Nws yuav tsum tau kuaj xyuas cov degree ntawm roundness, seb puas muaj qhov tsis xws luag xws li folds, misrounds, kab nrib pleb, inclusions, kinks, thiab loj mechanical puas nti, pits, tev, flashing, corrosion me ntsis, thiab lwm yam.

(2) Round tooj liab hlau

  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) Aluminium kab saum npoo

  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.

Tsis tas li ntawd, qhov vuam ib feem ntawm ib qho - hlau txuas yuav tsum sib npaug thiab qhov vuam yuav tsum tau ua los tiv thaiv- kev kho corrosion. Feem ntau, qhov loj ntawm qhov sib koom ua ke yuav tsum tsis pub tshaj ob zaug ntawm txoj kab uas hla. Qhov chaw vuam yuav tsum tsis pub tsawg tshaj 15 meters, qhov deb ntawm ob qhov chaw vuam ntawm tib txheej tsis yog tib lub xaim, txheej sab hauv yuav tsum tsis pub tsawg tshaj 5 meters, thiab txheej txheej sab nrauv yuav tsum tsis pub tsawg tshaj 15. meters. Thaum cov tub ntxhais tooj liab yog ib qho tooj liab hlau, vuam tsis raug tso cai.
