Momwe mungadziwire zingwe zotsika?

Wire and cable are indispensable materials for the transmission of power energy, and is widely used in economic production, once the cable fails, it will not only threaten the safe and stable operation of the power grid, but also cause significant economic losses to families and society. Now there are a lot of unqualified cables in the market to disrupt the choice of consumers with fake and shoddy, and the following will introduce the identification method of concentrated inferior cables.

1. 1.Yang'anani mosamala pa kusindikiza chizindikiro, tcherani khutu ngati pali typos kapena mithunzi yosiyana yosindikizira, mawuwo samveka bwino.

2. 2. Sonkhanitsani khungu loteteza ndi dzanja, ndipo mtundu wake ndi mawu osavuta kufufuta nthawi zambiri amakhala mizere yotsika.

3. 3.Kandani ndikutsina khungu lotsekereza ndi chala.Itt nthawi zambiri imakhala mzere wotsikirapo ngati ukhoza kukokedwa kapena kutsina.

4. 4.Ngati waya wa insulated wathyoka pambuyo popindika katatu mpaka kanayi, zinthu zomwe zimagwiritsidwa ntchito pazitsulo zimakhala zosauka kwambiri.

5. 5.Ignite the insulation layer. Ndi waya wocheperako ifcan imangoyaka yokha ikasiya lawi lotseguka.

6. 6.Aluminiyamu ndi mkuwa zimagwiritsidwa ntchito kwambiri pakatikati pa waya, ndi mtundu wa inferior coreis imvi ndipo palibe zitsulo zonyezimira.

7. 7.Measure the outer diameter of the insulated wire and the diameter of the core, the allowable error is ±10%, and if the measured value exceeds the allowable error, it is basically an inferior insulated wire.
