Enormous cable model industry penetration: a huge difference in the price of wire

July 29, 2020

In life, cables can be said to be ubiquitous. Cables are a kind of material that supplies electricity to us, so we should be careful about circuit engineering at home. In order to do a good job of the circuit, it is necessary to understand the relevant knowledge about the type and usage of the wire before purchasing it. Of course, the wire types used in different places are also different. If you don’t know much about cable models and their uses, you might as well come and follow me!

Cable definition

What is the cable? Cables have two meanings: Definition 1. A conductor made of one or more mutually insulated conductors and an outer sheathed insulating sheath that carries electricity or information from one place to another. Definition 2. A cable-like cable usually consisting of several or several sets of wires stranded. Each set of wires is insulated from each other and often twists around a center. The entire outer bread has a highly insulating cover.

Cable classification

What are the cable classifications? Cables mainly include: compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, and aluminum alloy cables. They are composed of single or multi-stranded wires and insulating layers for connecting circuits, electrical appliances, etc.

Cable use

1. Mainly overhead bare wires, busbars (bus bars), power cables (plastic cables, oil-paper cables (substituted by plastic power cables), rubber sleeve cables, overhead insulated cables), branch cables (replace some buses) , electromagnetic wire, and electrical equipment used in electrical equipment, such as wire and cable.

2. Cables mainly include local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communications, or other composite cables.

3, machinery and equipment, instrumentation system except this part, almost all other products have applications, but mainly power cables, electromagnetic lines, data cables, instrumentation cables and so on.

How to distinguish the quality of the cable

There are many types of wires on the market, many specifications, and prices are chaotic, making it difficult for consumers to choose. In terms of the prices of 2.5 square millimetres and 4 square millimetres of two kinds of copper wires that are commonly used in home decoration, the price of one line of the same specification may vary by 20% to 30% because of different manufacturers. As for the quality, whether the length is up to standard, consumers are even more difficult to determine.

According to professional sources, the price difference between wires is huge, mainly due to the difference in raw materials. The main raw materials are electrolytic copper, insulating materials and sheathing materials. In the raw material market, electrolytic copper ranges from RMB 50,000 per ton to only RMB 40,000 per ton of recycled copper. The quality of insulating materials and sheathing materials ranges from RMB 8,000 to RMB 10,000 per ton. The price of defective products ranges from 4,000 yuan to 5,000 yuan per ton. In addition, the lack of length and inadequate insulation of the insulators are also important reasons for price differences. The length of each line, excellent products is 100 meters, while the defective product is only about 90 meters; the insulation content of excellent products accounted for 35% to 40%, while the defective product is only 15%. By contrast, it is not difficult for consumers to see that the difference in the sales price of finished wire is due to the presence of tricky materials.

Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more pricing details, please contact your local dealer!
