How to check fake and inferior wires

weight

Wires of good quality are generally within the prescribed weight range. For example, the commonly used plastic insulated single-strand copper core wire with 1.5 cross-sectional area is 1.8-1.9 kg per 100 m, 2.5 plastic insulated single-strand copper core wire with 2.8-3.0 kg per 100 m, and 4.0 plastic insulated single-strand copper core wire with 4.1-4.2 kg per 100 m. Poor quality wires have insufficient weight, either insufficient length or excessive impurities in copper cores.

Manufactor

Fake and inferior wires are often "three without products", but there are ambiguous signs of origin on them, such as made in China, made in a province or a city in China, which is actually equivalent to unmarked origin.

Price

Because of the low production cost of fake and inferior wires, vendors often sell at low prices under the guise of low price and good quality, which makes people fall for it.
