In today's wire and cable market, there are many products and production companies of different levels. However, many buyers simply regard price as the procurement standard, which breeds a market with many substandard products. So, what kind of cables are produced in accordance with national standards?
What is a national standard electrical cable?
The national standard electrical cable, literally understood, is the wire and cable produced in accordance with the national standard. Our country has clear regulations on the appearance, mechanical strength, insulation of the sheath, pressure resistance, wire resistance, and other aspects of the cable. Different cables have different national standards, mainly as follows:
Irradiation cross-linked power cable (0.6/1KV) executive standard: GB/T12706.1-2008
Medium voltage cross-linked cable (6/6KV-26/35KV) executive standard: GB/T12706.2-2008
High voltage cross-linked cable (64/110KV) executive standard: GB/T 11017-[/B]2002
Control cable (450/750V) executive standard: GB9330-88
Aluminum stranded wire and steel core aluminum stranded wire (0.6/1KV) executive standard: GB/T 1179-1999
How to identify the national standard electrical cable?
- Ensure that the certificate of conformity is standard; find out if there is a quality system certification; if there is a factory name, site, inspection stamp, and production date; and if there are trademarks, specifications, voltages, etc. printed on the wires. It also depends on the cross-section of the copper core of the wire. The high-quality copper is bright in color. Otherwise, it is inferior.
- You can take a wirehead and bend it repeatedly by hand. An excellent product has a soft hand feel, good fatigue resistance, and no cracks on the wire insulator.
- Wires of good quality are generally within the specified weight range. Wires of poor quality have insufficient weight, either the length is not enough, or the copper core of the wire has too much impurity.
- The copper core of the qualified copper core wire should be purple-red, shiny, and soft. The copper core of the shoddy copper core wire is purple-black, yellowish or white, with a lot of impurities, poor mechanical strength, and poor toughness. During the inspection, you only need to peel off the wire at one end and rub a piece of white paper on the copper core. If there is a black substance on the white paper, it means that there are many impurities in the copper core. In addition, the insulating layer of fake wires seems very thick, but in fact, most of them are made of recycled plastics. Over time, the insulating layer will age and cause leakage.
