Introduce
Submarine cable penetration O-ring is commonly used in submarine cable compression gland cable penetrations. Their function is to keep the internal seal of the equipment. During the submarine cable laying process, the cable must pass through the cable penetration to ensure that the cable is insulated from the external environment and maintains pressure balance.
Advantages of Submarine Cable Penetration O-rings
- Water and gas sealing: O-rings provide an effective sealing mechanism to prevent water and gas from penetrating the pressure-resistant housing of the submarine repeater.
- Mechanical protection: O-rings can also absorb shock and vibration during installation and operation, thereby improving the mechanical stability of the cable system.
- Protect submarine cables from anchor impact: Submarine cables are particularly susceptible to impact and damage from anchors in shallow water areas. The design of O-rings can reduce the direct impact of anchors on cables, thereby protecting the structure and function of the cables.
- Reduce the free span during cable laying: By using O-rings and other technologies, the free span during cable laying can be reduced, thereby reducing the risk of damage that may be caused by excessive spans.
