1. Copper wire is the core of the entire power cord. The density of the copper wire directly affects the quality of the power cord.
2. The inner sheath is an insulating sheath. It can protect the copper wire from direct contact with the outside air to avoid leakage. The insulating sheath is closely related to the safety of the power cord.
3. The function of the outer sheath is to protect the power cord from corrosion, damage to external forces, and strengthen the mechanical strength of the power cord. This requires the beam processing to have high temperature resistance, low temperature resistance, resistance to natural light interference, good winding performance, high service life, and environmentally friendly materials.
4. Mechanical properties: Insertion force is an important mechanical property in terms of connection function.
