Nowadays, there are many types of wires sold in the market, and some inferior products are mixed in them, which seriously affects our electricity safety and has buried our lives with long-term hidden dangers.
Identification of the advantages and disadvantages of wires can be distinguished from the copper core material, the cross-sectional area of ​​the copper core, and the packaging and printing of the wires.
The copper core material of high-quality electric wire is a high-quality copper material with high purity and good electrical conductivity as a copper core material, and has a very good metallic luster. The inferior metallic wire has a poor metallic luster and can be clearly distinguished with the naked eye. The copper used for poor quality copper wire core material has high impurity content, high resistance, poor electrical conductivity, large power loss on the power line, and serious heat generation on the wire, which can not ensure the safety of use, and can easily cause damage to household appliances due to short-circuits. The more serious is that Poor wires can easily cause fire and seriously endanger the safety of our lives and property.
The cross-sectional area of ​​the high quality wire copper core is strictly in accordance with national electrical standards to ensure its safe use at rated current strength and rated voltage. In order to reduce the production cost of inferior quality wires, the cross-sectional area of ​​its copper core does not meet the national electrician standard, and its actual rated current intensity and rated voltage are not achieved in practical use. Such wires can easily cause damage to electrical circuits when you use high-power appliances.
High-quality wire packaging is very formal, each wire has a certificate of compliance, the National Electrotechnical Commission Great Wall certification mark and certification number printed on the certificate, also printed with the manufacturer name and contact address and the date of manufacture and inspection qualified seal. The Great Wall certification mark and certification number are also printed on the wire, as well as the wire type and rated voltage, and the printing is clear and the writing is firm. The certificate of poor quality wire is printed coarsely, the Great Wall certification mark and certification number are forged, and there is no manufacturer's name, contact address, or date of manufacture on the certificate. The writing on the wire is vague and easy to drop.
The electrician brand, Lixin brand, and Panda brand electric wire that we currently sell in B&Q are all certified by the Great Wall of the National Electrotechnical Commission.
The sales location is on the 30th channel.
The quality of the wire is related to your safety. Therefore, when choosing a wire, you must not be sloppy and greedy for cheap. High-quality wires will bring you safety, and inferior wires will bring you danger.

Manufacturing Industry Lighting
Industrial lighting is a lighting solution designed specifically for manufacturing environments. In the manufacturing industry, a good lighting solution is essential to improve production efficiency, ensure work safety and create a comfortable working environment.
Manufacturing lighting needs to meet a range of specific needs. First, there are high lighting requirements for factory lighting, because manufacturing environments often require a lot of light to ensure that employees can see details clearly when carrying out assembly, inspection, and other tasks. Second, reliability and durability are key, as manufacturing environments can have harsh conditions such as dust, vibration and high temperatures. Therefore, it is very important to use production lighting equipment with high impact resistance, dustproof, waterproof and other characteristics.
LED lighting technology has been widely used in warehouse lighting. LED lamps have the advantages of high brightness, long life, low energy consumption and low maintenance costs, which can provide efficient and reliable lighting solutions for the manufacturing industry. In addition, the intelligent control system can achieve dimming and color temperature and other functions, according to different work needs to flexibly adjust, improve energy efficiency.
Through rational planning and application of manufacturing lighting solutions, production efficiency, quality control and employee safety can be improved. Proper lighting reduces eye strain, improves accuracy, and ensures that employees can operate safely during the course of their work. The design of manufacturing lighting should consider factors such as environmental characteristics, task requirements, energy efficiency and reliability to create a safe, efficient and comfortable manufacturing environment.Manufacturing Lighting, Factory Lighting, Production Lighting, LED Lighting Technology, Warehouse Lighting
