  1. Plug (3.5/5.5/2.0/2.5/4.0 and other specifications)

  2. Wire (outer sheath, inner sheath, conductor, common transmission conductors include copper and aluminum metal wires, etc.)

  1. Outer sheath

  The outer sheath is also called the protective sheath. It is the outermost layer of the DC power cord. This outer sheath plays a role in protecting the DC power cord. The outer sheath has powerful characteristics such as high temperature resistance and Low temperature, resistance to natural light interference, good winding performance, long service life, and environmental protection of materials.

  2. Inner sheath

  Inner sheath: The inner sheath is also called an insulating sheath. It is an indispensable intermediate structural part of the DC power cord. The main insulation sheath is insulation, as the name implies, to ensure the safety of the DC power cord and allow the copper wire to be directly connected to the air. There will not be any leakage phenomenon, and the material of the insulating sheath should be soft to ensure that it can be well inlaid in the middle layer. The inner sheath is a layer of material that wraps the cable between the shielding layer and the core, usually polyvinyl chloride plastic or polyethylene plastic. There are also low-smoke and halogen-free materials. Use in accordance with the process regulations, so that the insulating layer will not come into contact with water, air or other objects, and avoid moisture and mechanical damage to the insulating layer.

  3. Copper wire

  Copper wire is the core part of DC power cord. Copper wire is mainly the carrier of current and voltage. The density of copper wire directly affects the quality of DC power cord. The material of the DC power cord is also an important factor for quality control, and the quantity and flexibility of the copper wire are also one of the factors to be considered.
