Why Must Cold Shrink Cable Accessories Have Heat Resistance?
Date: | Read: 1
Cables generate heat during load operation. If the Cold Shrink Cable Accessories lacks sufficient heat resistance, elastic materials may soften or even undergo structural deformation, thereby compromising sealing and insulation functions. Elevated ambient temperatures accelerate the aging process of accessory materials. Prolonged exposure to high temperatures causes silicone rubber or EPDM rubber to lose elastic resilience, resulting in insufficient clamping force and potential micro-cracks at interfaces.
