What is the production process of control cables?
The production process of control cables is a multi-link and high-precision manufacturing process. It needs to combine requirements such as electrical performance, mechanical strength and environmental adaptability, and achieve the transformation from raw materials to finished products through a systematic process. The following is a detailed analysis of its core steps and technical key points from the perspective of the entire process flow:I. Raw material Preparation StageConductor processingMaterial selection and testing: High-purity electrolytic copper (copper content ≥99.95%) or aluminum alloy is selected. The impurity content (oxygen content in copper < 0.02%) is confirmed through spectral analysis, and the resistivity of the conductor is tested (copper conductor ≤0.017241Ω · mm²/m at 20℃).Wire drawing process: A multi-pass wire drawing machine is used to draw copper rods into single wires of the target...

What factors can affect the quality of control cables?
The quality of control cables is influenced by multiple dimensions. From the selection of raw materials to the production process and usage environment, all these links may have a direct impact on their performance, reliability and service life. The following is a detailed analysis of the key influencing factors from a full-chain perspective:I. Raw material quality: The cornerstone determining the performance of cablesDefects in conductor materialsInsufficient purity: The use of impure recycled copper (such as copper content < 99.9%) or inferior aluminum alloy leads to an increase in resistivity (copper conductor resistivity > 0.017241Ω · mm²/m), severe heating, and even short circuits.Processing defects: Scratches, burrs, or insufficient annealing (elongation < 25%) occur during the wire drawing process of the conductor, resulting in poor flexibility and easy breakage during wiring.2. The insulating material is of poor qualityThe temperature resistance grade ...

What technical support is needed to provide customized power cable products for customers?
Surgical support system. The following is an explanation from the perspective of core technologies:1. Demand analysis and technical adaptation capabilitiesIndustry standards and working condition analysis techniquesStandard database: Establish standard libraries for power cables in various industries (such as national standards GB, international standards IEC, American standards UL, industry standards such as DL/T, YD/T, etc.) to quickly match the industry demands of customers (for example, cables used in rail transit need to meet the flame retardant and smoke density requirements of the TB/T 1484 standard).Working condition simulation technology: By using the environmental parameters (temperature, humidity, vibration frequency, corrosive medium, etc.) provided by the customer, simulation software (such as ANSYS thermal analysis module) is used to simulate the performance of the cable under extreme working conditions, verifying the feasibility of material selection and structu...
