Introduction to paper wrapped copper stranded wire products

Introduction to paper wrapped copper stranded wire products:

1： Structure and Composition

  Conductor: Made of high-purity copper material, copper has excellent conductivity, which can ensure low resistance and low loss of current transmission in the wire, ensuring the high efficiency of electrical energy transmission.

Insulation layer: Power cable paper, high-density insulation paper, heat-resistant insulation paper, high elongation fiber paper, aromatic polyamide paper (Nomex), etc. are usually used as insulation materials. These insulating papers have good electrical insulation properties, which can effectively isolate current, prevent safety issues such as short circuits and leakage.

2： Characteristics

  Good conductivity: Copper has excellent conductivity, and paper wrapped copper stranded wire can reduce energy loss during current transmission, ensuring the normal operation of electrical equipment and improving energy utilization efficiency.

Reliable insulation performance: The insulation paper layer can provide reliable insulation protection, isolate the copper stranded wire from the external environment, prevent current leakage and short circuit faults, and ensure personal safety and stable equipment operation.

  High mechanical strength: It has certain tensile strength and toughness, can withstand certain tensile and external forces, is not easy to break or damage during installation and use, and is suitable for various application scenarios.

Accurate external dimensions: During the production process, the dimensional accuracy can be strictly controlled to ensure that the product's external dimensions meet the standard requirements, making it easy to install and connect with other equipment.

Moderate wrapping tightness: The wrapping tightness of the insulation paper is just right, which ensures a tight bond between the insulation layer and the copper stranded wire, without damaging the copper stranded wire or affecting its performance due to excessive tightness, and also avoids the problem of insulation performance degradation or insulation layer detachment caused by excessive looseness.

  Good heat resistance: Some special insulation papers such as Nomex paper have high heat resistance, which can maintain good insulation and mechanical properties even in high temperature environments, extending the service life of the product.

Strong corrosion resistance: Both insulation paper and copper stranded wire have a certain degree of corrosion resistance, which can resist the erosion of corrosive substances such as acid and alkali in the external environment, making them suitable for harsh working environments.

3： Classification

  Classified by insulation material: It can be divided into ordinary power cable paper wrapped copper stranded wire, high-density insulation paper wrapped copper stranded wire, heat-resistant insulation paper wrapped copper stranded wire, Nomex paper wrapped copper stranded wire, etc. Different insulation materials endow products with different performance characteristics to meet different usage needs.

  Classified by stranded wire structure: there are single stranded copper stranded wire, multi stranded copper stranded wire, etc. Single stranded copper wire is suitable for some simple electrical connections and fixing occasions; Multi stranded copper wire has better flexibility and fatigue resistance, making it suitable for situations that require frequent bending or movement.
