Indlela yokubona izintambo ezingaphansi?

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.Bheka ngokucophelela ukuphrinta ilebula, qaphela uma kukhona ama-typos noma ama-shades ahlukene wokuphrinta, amagama afiphalisiwe.

2. 2.Sonta isikhumba esivikelayo ngesandla, futhi umbala namagama kulula ukuwasula kuvame ukuba yimigqa esezingeni eliphansi.

3. 3.Khwaya futhi uncinze isikhumba esivikelayo ngozipho.Imvamisa umugqa ongaphansi uma ungadwetshwa noma uncishwe.

4. 4.Uma i-insulated wire iphuka ngemva kokugoba kathathu kuya kwezine, i-material ye-insulation layer ngokuvamile impofu kakhulu.

5. 5.Kokhela ungqimba lokufakelwa. Intambo engaphansi uma ikwazi ukuvutha ngokuzenzekelayo ngemva kokushiya ilangabi elivulekile.

6. 6.I-Aluminium nethusi kuvame ukusetshenziswa enkabeni yocingo, kanye nombala we-inferior coreis grey futhi ayikho i-metallic luster.

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.
