Misunderstanding one, only plans cheap, do not ask the wire source
There are tens of thousands of existing wire and cable companies in China, different manufacturers, different materials, different labor force, and transportation and management costs, leading to even a certain difference in price even if the same size wire.
As we all know, because the safety of wires and cables is related to the lives and property of the people, the country is extremely strict in the control of wires and cables. When a wire and cable enterprise meets the national standards, it often goes through screenings in many fields such as material selection, production process, safety factor, and quality inspection, as well as the application and approval of related contents. This directly increases the cost of wires and cables.
This is why regular manufacturers' products tend to be higher in price than non-regular manufacturers. If it is only for the sake of cheap prices and purchases of wires made by non-regular manufacturers and even counterfeit products, then it will inevitably cause hidden dangers to household electricity security.
Misunderstanding II, only look at the appearance of the wire, do not look at wire specifications
Different electrical appliances and different environments have different requirements for wire specifications. For example, a user needs to purchase a power cord for a 380V welding machine. The current required by the welder is 16 amps. If we use ordinary wires for home use, it is obviously impossible to carry such a large current and it is difficult to meet the requirements for safe electricity use.
Because of the increase of voltage and current, it is necessary to put forward higher requirements for parameters such as bearing capacity and conductivity of wires and cables. If you use ordinary wires directly, it is very likely that you will cause a short circuit in the circuit and the machine will be burned. In severe cases, it will cause a great loss such as overheating in your home.
Another example is that wires that are often exposed to high temperatures cannot use even thicker rubber sheathed wires. Instead, fire-retardant flame-retardant wires should be selected so as to avoid short-circuiting of the wires due to scorching of the sheath.
Therefore, when purchasing electric wires, it is necessary to take into account the current, voltage requirements, and working environment of their own electrical appliances, and consult with professionals and wire and cable distributors to select products of suitable specifications so as to avoid loss of production and economy.
Home life, I am afraid that few people did not buy wires. But when asked how to pick it up, many people find it difficult to say one or two. Because many people lack common knowledge about the purchase of wires and cables, there are often some misunderstandings on the purchase.
