The harmful effects of using poor quality electrical wires are numerous, from the risk of fire and explosion, damage to electrical equipment, to wasting energy and reducing the life of the electrical system. Therefore, in this article, QNT Investment and Trading Services Company Limited will share experiences in choosing safe and suitable electrical wires for homes, including important criteria such as material, durability, load capacity and quality certifications, to ensure the electrical system operates stably and safely for a long time. Please refer to it!
1. Harmful effects of using poor quality electrical wires
The demand for electrical wires is increasing, so more and more units supplying poor quality electrical wires are born to gain high profits from customers. However, the harmful effects of using poor quality electrical wires are unpredictable
When the copper core is of poor quality or does not have enough cross-section, it can cause the following harmful effects:
– Poor electrical conductivity, causing voltage drop on the line, making the device operate inefficiently, reducing the life of the device quickly.
– Excessive heating on the line, causing damage to the insulation layer, causing short circuits and explosions.
– Poor quality copper cores are very easy to break, difficult to connect, and difficult to install into other electrical accessories.
When the insulation is of poor quality, it can cause the following harmful effects:
– Cracked insulation, exposed conductor, causing electric shock to people.
– Cracked insulation after a short time, causing electric leakage, power loss, short circuits and explosions.
– Cannot withstand the allowable temperature of the core, causing it to melt and cause short circuits and explosions.
– Does not turn off automatically when ignited by external factors.
– Discolors after a short time, causing confusion between wires when repairing or replacing.

2. Experience in choosing electrical wires for houses
Whether the electrical wires are safe and durable or not depends largely on how you choose the electrical wires for your house. Therefore, you should refer to our experience in choosing electrical wires for houses below to help protect the safety and save money for your family!
With so many types of electrical wires on the market today, there are good ones, bad ones, real ones, fake ones, and even types of wires without labels or manufacturer names. Therefore, choosing which wire or brand can be trusted is not an easy task. With some of our experience, this guide gives some recommendations and signs to hopefully help users avoid poor quality electrical wire/cable products:
– Do not choose wires without labels on the packaging, without the manufacturer’s name, without a clear address.
– Do not choose a wire that does not have basic information on it such as: brand, wire type name, cross-section, core structure (number of strands and diameter of each strand), and manufacturing standards.
– Good wires often have a shiny, smooth plastic shell on the outside.
– The insulating plastic layer of a good wire is very flexible, when stripped from the core, it can be stretched to double or triple its original length without breaking. The wire can be bent many times or twisted, but the insulating surface will not crack.
– The core can be checked by counting the number of small strands inside compared to the number of strands written on the outside. The diameter of the small strands inside is very difficult to check, because it requires a special ruler to measure. However, with a reputable brand, the core structure (number of strands and diameter of each strand) is specifically written on the wire, so it can be trusted.
– A good wire has a bright, shiny core, if it is a copper wire, the core is very flexible. For copper core wires with many small strands, you can easily twist the core wires with two fingers without the small strands coming loose, breaking, or stabbing your hand. For single-strand core wires, you can bend the copper core wires dozens of times without breaking.
– Normally, good wires are more expensive than poor quality wires of the same size.
We hope that customers will gain more experience for themselves to help protect the safety of the whole family!
