Choosing flexible copper stranded wire requires comprehensive consideration based on specific applications and technical requirements. Here are several key selection steps and precautions:
1. Clearly define the purpose and requirements
-Electrical performance requirements: such as current carrying capacity, voltage level, etc.
-Flexibility requirement: Whether high flexibility is required for dynamic or fixed installation.
-Environmental conditions: whether exposed to special environments such as high temperature, low temperature, humidity, chemical corrosion, etc.
2. Copper wire specifications
-Conductor cross-sectional area: Select the appropriate cross-sectional area based on the load current, usually following relevant electrical design specifications.
-Twisted wire structure: The more strands, the finer the single strand, and the better the flexibility. Suitable for occasions that require frequent bending.
-Conductivity: Choose high-purity oxygen free copper (conductivity greater than 99.9%) to ensure electrical performance.
3. Insulation and sheath materials
-PVC (polyvinyl chloride): economical and suitable for ordinary environments.
-Silicone rubber: high temperature resistance, good flexibility.
-Polyurethane (PU): wear-resistant, strong oil resistance.
-Zero halogen low smoke material: suitable for occasions with high fire prevention requirements.
4. Flexibility level
-Flexible copper stranded wires are classified into ordinary flexible, ultra flexible, and special flexible according to different usage environments.
-Super flexibility is commonly used in high bending applications such as robots and drag chain cables.
5. Environmental resistance performance
-Temperature range: Confirm whether the temperature range of the cable in the working environment meets the requirements.
-Corrosion resistance: Select corresponding corrosion-resistant sheaths for cables that may be exposed to oil stains, acid and alkali environments.
6. Certification and Standards
-Confirm that the product complies with relevant standards, such as IEC, UL, VDE, etc.
-For cables in special industries such as healthcare and aviation, specific certification requirements must be met.
7. Supplier and brand selection
-Choose suppliers with good reputation and reliable quality to ensure product consistency.
-Understand after-sales support and warranty terms.
8. Cost and cost-effectiveness
-Taking into account price, service life, and maintenance costs while meeting technical requirements.
Before making a choice for Flexible Copper Stranded Connector, it is advisable to communicate the actual requirements in detail with the supplier and have them recommend suitable product models. At the same time, ensure to obtain the technical parameter table to verify whether the product meets the standards.
