It is a wire produced completely in accordance with the national standard. Generally, household and common wires are of standard specifications and performances. The national standard stipulates common specifications and performances.
Editing of measurement standards
, appearance standard wires must have certification mark, manufacturer, wire diameter, etc. Yellow-green insulation layer for ground wire
, mechanical strength
, insulation of sheath (generally greater than) and withstand voltage strength (below)
, wire resistance (not greater than a certain resistance under a certain wire diameter, conductivity, and length)
, wires must not be exposed to low-temperature shocks under high temperature Cracks etc. occur.
Edit the difference between national standard and non-national standard wire

, to see
See Whether there is a quality system certification, check whether the certificate is standardized, whether there is the factory name, factory address, inspection seal, production date, and whether the trademark, specifications, voltage, etc. are printed on the wires. It also depends on the cross-section of the copper core of the wire. The high-quality copper is bright and soft in color, otherwise it is a defective product.
, Want to try
You can take a piece of wire and bend it repeatedly by hand. Any wire that feels soft, has good fatigue resistance, has high plastic or rubber feel and has no cracks in the wire insulator is a high-quality product.
, Weighing
Good quality wires are generally within the specified weight range. For example, the commonly used cross-sectional area is. Each plastic insulated single-strand copper core wire weighs... The plastic insulated single-strand copper core wire weighs ~. . The plastic insulated single-strand copper core wire weighs...etc. Poor quality wires have insufficient weight or insufficient length or too much impurities in the copper core of the wire.
, Look at the copper quality
The copper core of qualified copper core wires should be purple-red, shiny, and soft to the touch. The copper core of fake and inferior copper core wires is purple-black, yellowish or white, has many impurities, has poor mechanical strength, and has poor toughness. It will break with a little force and there are often disconnections in the wires. When checking, you just need to peel off one end of the wire and rub it on the copper core with a piece of white paper. If there is black substance on the white paper, it means there are more impurities in the copper core. In addition, the insulation layer of fake and inferior wires seems to be very thick. In fact, most of them are made of recycled plastic. Over time, the insulation layer will age and leak electricity.
