FAQ
What are the product quality issues of wires and cables?
The quality of wires and cables affects the efficiency and stability of power transmission. Low-quality wires and cables are prone to fire, equipment damage and electric shock accidents. Strict material selection, advanced technology and enhanced quality control are required. Shuobang Cable has its own factory, and the means to improve quality include optimizing conductor structure, innovating insulation materials and intelligent production. Shuobang Cable calls for enhancing quality awareness and choosing high-quality products.
Differences between rubber cables and polyvinyl chloride cables
The main differences between rubber cables and polyvinyl chloride cables are materials, performance characteristics and application fields.
1. Material differences: Rubber cables are made of rubber, which are soft and have good high temperature and corrosion resistance; while polyvinyl chloride cables are made of polyvinyl chloride resin, which are relatively cheap and easy to produce.
2. Performance characteristics differences: Rubber cables have good wear resistance, weather resistance and high temperature resistance; polyvinyl chloride cables have good electrical insulation, wear resistance and corrosion resistance.
3. Application field differences: Rubber cables are widely used in industrial equipment, household appliances and other fields, such as high-temperature electric furnaces, power tools, etc.; polyvinyl chloride cables are widely used in construction, home decoration, communications and other fields, such as building wires, communication cables, etc. In summary, rubber cables and polyvinyl chloride cables each have their own unique advantages and application scenarios, and the selection needs to be considered according to specific needs.
Why does the sheath of concentric cable have bubbles?
1. Material problem: If there are quality problems with the cable sheath material itself, such as poor material stability or unstable components, bubbles may appear during the production process. For example, if the components of ordinary two-step silane cross-linked polyethylene materials are not mixed evenly, or the proportion of cross-linking agent and a small amount of antioxidant is not appropriate, bubbles may appear in the sheath during extrusion.
2. Improper temperature control during production: If the temperature control during production is not appropriate, such as local temperature control is too high, or the extrusion temperature is too high, it may cause plastic scorching or “slipping”, which will affect the uniform plasticization and extrusion of the plastic, resulting in bubbles in the sheath.
3. Plastic is moist or contains moisture: If the plastic material used is moist or contains moisture, the moisture may turn into steam at high temperature and form bubbles. Especially during processing, if the excess gas in the plastic is not removed or it is processed in a humid environment, bubbles may appear in the sheath.
Can the copper content of concentric cables be higher?
The conductor material of copper core cables is mainly pure copper, which has excellent conductivity and low resistivity, and can ensure high cable transmission efficiency. Pure copper has very good conductivity, which can effectively reduce power loss and improve the efficiency and reliability of cable use. In addition, copper also has good magnetic conductivity and anti-electromagnetic interference performance, which helps to increase the service life of the cable. Therefore, in order to improve the performance and reliability of the cable, you can request a higher copper content in the demand form when placing an order.
Do you have an advantage in terms of price?
The production cost of Shuobang Cable is relatively low, which is mainly due to the advantages of raw material procurement, production technology and labor costs, forming an efficient supply chain system, which enables Shuobang Cable to enter the international market at a more competitive price.
