Electronic wiring harnesses are widely used in our daily lives. They are commonly used in all kinds of small home appliances or electrical appliances, such as: power banks, charging cables, water dispensers, juicers, TVs, air conditioners, etc. Customers are ordering When it comes to electronic wiring harnesses, there may be such questions. Why are there differences in prices for the same electronic wiring harness?
1. Non-certified, non-tested electronic wiring harnesses have low cost
Electronic wiring harnesses are classified as weak wires, but they are widely used in industry. The production of electronic wiring harnesses should comply with relevant technical specifications and conform to relevant inspection arrangements. In the wire industry, UL758 and UL1581 related to UL Center in the United States are widely used. Technical specifications, and must obtain the UL certification of the American UL company, after SGS testing, etc., wire industry companies, in order to be able to meet the relevant specifications required by UL, the annual qualification and skill maintenance costs are as high as hundreds of thousands, and the wires that fail to obtain the UL certification Although the manufacturer does not have the qualification cost and maintenance cost, the unit price is low, but due to the lack of relevant regulations, it may be full of poor products using inferior copper wires and inferior rubber materials. The conductive function of these inferior products may not be as good as iron wires. In actual use It is easy to cause electrical accidents.
2. Some unscrupulous manufacturers cut corners in the production of electronic wiring harnesses
Nowadays, there are many standards and types of electronic wiring harnesses. Manufacturers cannot understand the product standards of each electronic wiring harness. Some unscrupulous manufacturers start with the copper standard of electronic wiring harness. For example, the electronic wiring harness has 16 copper wires. 15 copper wires, these cut corners, although the price is lower, often fail to meet the relevant technical specifications.
3. The raw materials are different, the price difference is big
The main raw materials for the production of electronic wiring harnesses are insulating materials, copper wires and sheathing materials. For now, the raw materials for electronic wiring harnesses such as copper wires and insulating materials are strictly required to be new electrolytic copper, insulating rubber materials, etc., but some manufacturers choose Recycled second-hand copper wire and second-hand rubber material have lower raw material costs. However, the lack of purity of second-hand copper wire, poor conductivity, and the lack of rubber content in second-hand rubber materials and insulators are all likely to cause electrical accidents, which deserve our vigilance.
