Waterproofing of cable connectors and repeaters for deep-sea exploration equipment

2025-09-11

Applications: Subsea observation network junction boxes, deep-sea towed cable terminations, and stress relief sections for underwater connectors.

Challenges: Intense pressure at depths of thousands of meters, corrosion from seawater penetration, and mechanical fatigue from cable swinging.

Solution: Potting inside the connector and at the cable end creates pressure compensation and a complete seal.

Core Value: Elastomeric silicone effectively transmits and balances external water pressure, preventing "popcorn" failures. Providing excellent waterproof sealing and stress buffering, it protects expensive underwater connectors and is a key material in the construction of the National Undersea Scientific Observation Network.
