Description

technical field [0001] The invention relates to a preparation method and material of a cold-shrink sealing pipe material. Background technique [0002] Cold-shrinkable cable accessories are made of elastomer materials (commonly used silicone rubber and ethylene-propylene rubber) in the factory for injection vulcanization, and then expanded in diameter and lined with plastic spiral supports to form various cable accessories. When installing on site, put these pre-expansion parts on the treated cable ends or joints, pull out the inner supporting plastic spiral strip (support), and press it on the cable insulation to form a cable accessory. Because it depends on the elastic retraction force at room temperature, instead of being heated and shrunk by fire like heat-shrinkable cable accessories, it is commonly called cold-shrinkable cable accessories. The early cold-shrinkable cable terminals only used silicone rubber cold-shrink parts for additional insulation, and the electric ...
