Cable manufacturers analyze the precautions of wires and cables for you
In daily life, wires and cables bear the important mission of transmitting electricity. Once their quality is not up to standard, accidents such as fire and electric shock are very likely to occur. Those major accidents caused by cable fires not only burned a large number of cables, but also cost a lot of money, time and effort to restore and rebuild, and caused a loss of electricity of up to 10 billion yuan. There are also fires caused by cable line failures, which have caused many deaths, the loss of lives, and the shattering of families. Behind these tragedies, substandard wires and cables are the culprits. Not only that, substandard wires and cables may also cause damage to electrical appliances, bringing many inconveniences and economic losses to our lives.
Some small wire and cable production enterprises have outdated production processes, outdated equipment, lack of professional technical personnel, and strict quality control systems. In the control of insulation and sheath thickness, there is a large error. Some insulation layers are too thin, resulting in a decrease in voltage resistance and easy breakdown, causing leakage or short circuits; Some protective layers are too thin and have insufficient mechanical protection capabilities, making them prone to wear and cracking, resulting in exposed internal structures. The non-standard production process is also an important reason for product quality problems.
Facing the dazzling array of wire and cable products on the market, how can we develop a pair of sharp eyes and distinguish their advantages and disadvantages? Firstly, the appearance can be observed. High quality wire and cable insulation layers and sheaths should have uniform texture, smooth surface, and no defects such as bubbles, cracks, sand holes, etc. The presence of bubbles in the insulation layer may cause partial discharge during use, leading to electrical faults. For copper cores, high-quality copper wire has a bright red color and a soft touch; Poor quality copper wire is generally purple black, slightly black, yellow or white in color due to the presence of many impurities, and has poor toughness and high hardness.
Proper use and maintenance of wires and cables are crucial for ensuring electrical safety in daily life. When installing wires and cables, it is necessary to follow reasonable wiring principles, avoid cross winding of lines, and reduce electromagnetic interference and fire hazards. When using wires and cables, strictly follow their rated current carrying capacity to avoid overload operation. Overload can cause cable temperature to rise, accelerate insulation aging, shorten cable life, and even trigger fires. Regularly inspect the appearance of the cable to see if there are any signs of damage, aging, overheating, etc. If there are any problems, they should be dealt with in a timely manner. The quality of wires and cables is directly related to the safety of our lives and property. Unqualified wires and cables are hidden "time bombs" in homes, which can cause disasters at any time.
When choosing wires and cables, we must keep our eyes open and choose products produced by legitimate manufacturers with qualified quality. We must not be tempted by cheap prices and lose big for small gains. At the same time, in the process of use and maintenance, it is also necessary to strictly follow the standard operation, conduct regular inspections, and promptly eliminate hidden dangers. Let's take action together, reject hidden dangers, use electricity safely, and create a safe and reliable living environment for ourselves and our families.
