Which outcome sharply accelerates polyethylene degradation on a power cable?

💡 Explanation

Increased UV exposure initiates chain scission via a photochemical process; this depolymerization sharply increases the degradation rate because shorter chains are less stable, therefore UV accelerates polymer breakdown, rather than methods that preserve them.
