Buying wires and cables need to get out of these misunderstandings

It is precisely because many people lack the common sense of purchasing wires and cables, so there are often some misunderstandings in purchasing. The common phenomena are as follows:

Misunderstanding 1. Only the price is cheap, not the source of the wire

     There are tens of thousands of wire and cable manufacturers in my country, different manufacturers, different materials, different labor, transportation and management costs, resulting in a certain difference in price even for wires of the same specification. As we all know, since the safety of wires and cables is related to the safety of people's lives and properties, some areas are extremely strict in the gatekeeping of wires and cables. When a wire and cable company that meets the standards is in production, it often has to go through various screenings such as material selection, production process, safety factor, quality inspection, etc., as well as the application and approval of related content, which directly increases the cost of power cable.

     This is why the products of regular manufacturers are often more expensive than those of informal manufacturers. If you are just greedy for cheap prices, and buy wires or even fake and shoddy products produced by those informal manufacturers, then it will inevitably cause hidden dangers to the safety of household electricity.

     Misunderstanding 2, only look at the appearance of the wire, not the wire specification

     Different electrical appliances and different environments have different requirements for wire specifications. For example, a user needs to buy a power cord for a 380V welding machine. The current required by the welding machine is 16 amps. If we use ordinary household wires, obviously it cannot carry such a large current, and it is difficult to meet the requirements of safe electricity use.

     Due to the increase of voltage and current, higher requirements must be put forward on various parameters such as the bearing capacity and conductivity of wires and cables. If ordinary wires are used directly, it is very likely to cause a short circuit of the line, burn the machine, and in severe cases, cause huge losses such as overheating in the home.

     Another example is wires that are often exposed to high temperature environments, and even thicker rubber-covered wires cannot be used. Instead, choose fire-resistant and flame-retardant wires to avoid the problem of short-circuiting the wires due to the scorched sheath.

      Therefore, when purchasing wires, you must consider the current, voltage requirements and working environment of your own electrical appliances, and consult professionals and wire and cable sellers to choose products with appropriate specifications to avoid production and economic losses.

      Misunderstanding 3: Only the picture is convenient and easy, regardless of the relevant elements

      Source, specification, price, and appearance are the basic elements that should be considered when purchasing wires. But when selling electric wires, I often see some people buying electric wires at random, often choosing one type, and going away without even asking about price, specification, or appearance.

      Among these people, some are busy with work and have no time to choose; some are because there are too many things to do and have no mood to choose; some are because they have purchased fewer wires and feel that there is no need to choose; In fact, the quality and specifications of wires vary widely, so you should ask them clearly and pick them carefully. Otherwise, it is convenient and hassle-free for a while, but once something goes wrong, it will be too late to even regret it.
