>>>> What is the national standard cable?

The national standard cable is literally understood to be a cable and wire produced strictly in accordance with national industry standards. In our country, there are clear regulations on the appearance of cable lines, impact toughness, insulation layer of wire sheath, compressive strength, wire resistance and other levels, different types of cable lines have different national industry standards, the key has the following categories:

Irradiation crosslinked wire and cable (0.6/1KV) Product implementation standard: GB/T12706.1-2008

High voltage crosslinked cable (6/6KV-26/35KV) Product implementation standard: GB/T12706.2-2008

High voltage crosslinked cable (64/110KV) Product implementation standard: GB/T11017-[/B]2002

Frequency conversion cable (450/750V) Product implementation standard: GB9330-88

Aluminum strand and steel core aluminum strand (0.6/1KV) product implementation standard: GB/T1179-1999

>>>> How to identify the national standard cable?

Need to see

National standard cable to see whether there is a quality management system certification mark; To see whether the certificate is the standard; See if there is the name of the enterprise, the place of production, the testing stamp, and the date of manufacturing; See whether the cable is printed on the trademark logo, specifications, models, working voltage, etc. You also need to see the cross-section of the copper core of the cable, high-quality red copper color bright, mild color, or it is scrap.

Going to try

It can be bent continuously with a cable head, provided that the touch is soft, the fatigue resistance is good, the plastic or vulcanized rubber has a large touch ductility and there is no crack on the cable conductor and insulator. ‍

weigh

Cost-effective cable lines are generally in the required net weight category. Such as the common cross section of 1.5 mm 2 plastic insulation layer of single copper copper core cable, the net weight per 100 meters is 1.8 ~ 1.9kg; 2.5mm 2 plastic insulation layer single copper copper core cable, net weight of 3 ~ 3.1 kg per 100 meters; The net weight of the cable with poor quality is not enough, or the length is not enough, or the copper core residue of the cable is too much.

brassware

The copper core of the copper cable should be dark purple, with gloss and soft touch. The fake and shoddy copper core cable copper core is purple black, dark or purple, there is a lot of residue, poor impact toughness, poor ductility, it will break with a little effort, and there is often a disconnection in the cable line. When checking, you only need to peel off one end of the cable 2cm, and then rub a piece of white paper on the copper core slightly, if there are gray and black chemicals on the thin paper, it indicates that there is more residue in the copper core. In addition, the cable sheath looks as if it is very strong, in fact, most of it is made of recycled particles, and over time, the cable sheath will embrittlement and electricity. ‍

Depend on the price

Because of the low cost of making fake and shoddy products national standard cables, businessmen often sell in the market under the banner of cheap and high-quality market sales, so that people are deceived.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
