Are you out of these misunderstandings when purchasing wire and cable?
There are tens of thousands of wire and cable companies in the market. Different manufacturers, different materials, different labor, different transportation and management costs can lead to different prices for wires of the same specification.
As we all know, because the safety of wires and cables is related to the safety of people's lives and property, the country is extremely strict with the wiring of wires and cables. A wire and cable company that meets the national standards often has to go through many aspects 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 wires. and cables.
This is why products from formal manufacturers tend to be more expensive than those from informal manufacturers. If you only want to buy cheap wires, or even fake and shoddy products, it will inevitably bring hidden dangers to the safety of household electricity.
Misunderstanding 2 Only look at the appearance of the wire, not the specifications of the wire
Different electrical appliances and different environments have different requirements on the size of wires. For example, the user needs to purchase a power cord for a 380V welder. The current required by the welder is 16 amps. If we use ordinary household wires, it is obviously impossible to 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, it is necessary to put forward higher requirements for various parameters such as carrying capacity and electrical conductivity of wires and cables. If you use ordinary wires directly, it is likely to cause a short circuit and burn the machine. In severe cases, it will cause huge losses such as overheating in the home.
Even thick rubber wraps are impossible if the wires are constantly exposed to high temperatures. Instead, choose fire-resistant and flame-retardant wires to avoid short-circuit problems caused by scorched sheaths.
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 dealers to choose products with appropriate specifications to avoid production and economic losses.
Misunderstanding three pictures are convenient and easy to operate, regardless of related elements
Source, gauge, price and appearance are the basic elements that should be considered when purchasing wire. However, when selling wires, I often see some people buying wires casually.
In fact, the quality of the wires varies widely, and the gauges vary. You should ask for a clear and careful look.
