How Do Cold-shrink Cable Accessories Shrink The Sheath To A Tight State?
The elastomer is typically made of silicone rubber or EPDM, materials that possess excellent elastic recovery capabilities. During manufacturing, the elastic tube is expanded to a size larger than the cable diameter and internally reinforced with a retractable support. During on-site operations, Wall Switch is slid to the predetermined position. After the support is removed, the elastic material returns to its original size, and the sleeve is tightly wrapped around the cable surface, thus forming a stable electrical insulation barrier and external sealing layer on the entire accessory interface.
