The impact of unqualified insulation sheath quality

It will affect the service life of the plug power cord. During long-term operation of the power cord, such as in kitchens and bathrooms, it will be corroded by oil fumes and water vapor. Due to prolonged exposure to external media, the insulation and mechanical properties of the cable sheath will decrease, and even lose its insulation protection function. It can cause safety accidents, short circuits leading to fires or electric shocks that endanger everyone's life and property safety. In addition, the plug power cord generates a large amount of heat when powered on for a long time, which also becomes a major factor affecting its service life.

So how is the insulation sheath of power cord cables considered qualified? The appearance of the sheath shall be smooth and round, with uniform gloss, no core deflection, no mechanical damage, flat compression, no sundries, bubbles, sand holes or obvious particles, knots, Fried Dough Twists, etc.

The conductor, insulation layer, and twisting distance of the plug power cord cable are strictly controlled according to standard requirements. This requires us to strictly follow the standard requirements during the production process of power cables, such as insulation layer thickness and sufficient plasticization of insulation materials. This approach can not only ensure the quality of power cables, but also save resources and reduce the material cost of power cables.
