Poor Insulation Quality

Some manufacturers use recycled plastics and excess fillers to cut costs. This results in insulation with low tensile strength and poor flame resistance. Thin, weak insulation can easily lead to short circuits and electric shock hazards.

Inferior Copper Conductors

Quality cables use 99.9% pure electrolytic copper. Substandard versions often contain impure or recycled copper with unstable copper content. This increases electrical resistance, causing energy waste and dangerous overheating that can damage insulation and start fires.

Inaccurate Dimensions

Non-compliant cables often have undersized conductors and shorter lengths. For example, a cable labeled 2.5mm² might actually be only 1.6mm in diameter. This reduced capacity leads to overheating under normal loads.
