The primary purpose of cable sealing is to prevent foreign matter from invading the cable interior, ensuring safe operation. Specifically, cable sealing performs the following functions:
1. Prevents foreign matter such as dust, water, and gas from invading the cable interior, potentially causing short circuits, open circuits, and other faults.
2. Improves the cable's waterproof, moisture-proof, and dust-proof properties, extending its service life.
3. Improves cable safety, reducing the risk of fires, explosions, and other accidents caused by cable faults.
