Recently, cable practitioners have reported a common problem: the sale of standard cables has become extremely difficult. We found that some substandard cable merchants advertise that they sell l standard cables, and the price is more than 10% cheaper than standard cables, which makes people feel helpless.
The following four points are the key factors for the price difference between standard cables and substandard cables.
- Based on weight cost of copper. The copper material of the standard cable is an oxygen-free copper, while the substandard cable maybe is not. Scrap copper and oxygen-free copper have the same weight, but the price is 10% different. The hard publicity of standard cables failed, and the price difference between standard cables and substandard cables reached 10%.
- Cut corners hidden in cable insulation and jacketing materials. As the country's supervision of cable resistance becomes more and more stringent, and the inspection of conventional products is also more stringent, substandard cables begin to look for opportunities in cable insulation materials and sheath materials. In the cable cost, if the copper material accounts for 70%, then the cable insulation and sheath material cost accounts for about 20%. If the insulation and sheath materials used are slightly worse, the price of substandard cables can be 5% lower than that of standard cables. Some cable problems that have been exposed recently are mainly focused on cable insulation and sheath materials.
- Short meters of wires and cables. In fact, the problem of short meters of wires has always existed, but the detection is increasing day by day. This problem often appeared on BV lines before. For example, the standard 100m/roll wire is actually only 95m, 98m, 90m, etc. Nowadays, with the increase of inspection items, such problems have been included in the special topic, and non-standard cables have begun to work in this area, hoping to attract everyone's attention.The
- cable is thick at both ends and thin in the middle. That is to say, the two ends of the cable conform to the standard cable, and the middle part is a substandard cable. This saves a lot of cost and the cable price will be lower as a result. However, it is impossible for the investigation cable to be cut in the middle, which creates this "loophole".
Currently, the most worrisome point is the fourth point. As long as the user unit and the cable manufacturer jointly keep secrets, it is difficult to verify. It is for this reason that although they are both " standards", the prices of cables are so different.
