Causes of yellowing and aging of wire sheath

Long-term high temperature radiation, ultraviolet irradiation, oxygen oxidation will cause the sheath to turn yellow.

Poor raw materials, long storage time and damp environment will also accelerate yellowing and aging.

Yellowed wires need to be checked in time to prevent insulation performance decline.
