How can cable manufacturers teach $'☆you to distinguish the qualit>αy of power cables?

The information comes from: internβ↑et  Published on: 2024-09-12

Wire and cableThe quality of the p✔σ♣¥roduct is closely related to the safety • of its use. When purc♥ hasing cables, it is ne €‍​cessary to buy qualified wi​≤§res and cables. Let me int♣≠roduce how to distinguish the××<∏ quality of cables:

1. Upon closer inspection of the trad​÷emark printing sample, the haφδndwriting is blurry and the"×<< address is unknown. It refers to lo¥₽↓oking at the printed words on£↔↑ the label and insulat↔εion skin. If there are spelε♣↔ling errors, uneven printing depth, or  'πλblurry words, attention ≤™‌‍should be paid.

2. Rubbing the insulation skin by hand↑₽® may result in color®↔≠ fading and poor quality. I£±≠t refers to rubbing tγ"®he insulation outer layer with fing•→ers. Some low-quality insu→₽εlation wires are pro£¥ne to color fading, especi §ally red wires. After rubbing, the colγ∑∑or of the wire skin left oΩ×±n the fingers or the words→§₹  printed on the wire sk✔‍in are usually erase∏₽d, indicating poor quality wires.

3. Then use your nails to  ♦‍scratch and pinch the‍♠ thread, as well as cut and €≥remove the skin line. ItφεΩ© refers to using nails to¶✘Ω™ scratch and pinch the  ☆insulation outer layer♣€→ , and the piece that can be scrat✔¶ched or pinched off is usua÷↕lly a low-quality wire.

4. Repeatedly bend the →σ¶×insulated wire, and it w≠§ill break three to four tε₩imes. It refers to repeatedly bendingλ' insulated wires. Poor qual← ♦☆ity wires usually have poor insulation γ★materials, and after bending 3-4   ≠•times, their insulation layer wil∑×l break.

5. Ignite the insulation of t∏÷ €he wire with fire andα&'∏ leave the live wire to self ignite. It✔® refers to the inferior wire that igniαΩ®βtes the insulation layer aε★'nd can self ignite after leaving β↓≥the open flame.

6. Aluminum and copper are commonly use✘&λπd for wire cores, which have a ™<✘→darker color and light©←er luster. It refers ‌Ω←♣to the color of the wire core. Poo<↕‍r quality wire has a dull€♦¥ color and no metallic luster.
