High Power 18-Core Subsea Underwater Connector

The High Power 18-Core subsea connector is Shanghai Kabel Intelligence Technology Co., Ltd's largest standard power connector, providing 18 high-current contacts rated up to 600 V DC/AC in a single IP68-sealed stainless steel body. It is designed for large ROV systems, offshore winch drives, and subsea power distribution infrastructure requiring high channel counts in a single penetration.

Key Specifications

Applications

• Large work-class ROV power umbilicals
• Subsea power distribution units
• Offshore winch and drive systems
• AUV multi-motor power management
• Subsea observatory power nodes

Frequently Asked Questions

How does an 18-core connector handle heat dissipation?

At 25 A per contact, the 316L stainless steel body and polyurethane boot dissipate heat effectively into the surrounding seawater. For continuous high-current operation, we recommend calculating total heat load and confirming with our engineering team.

Is this available in a panel-mount (bulkhead) version?

Yes -- both inline (cable-to-cable) and bulkhead (panel-mount) configurations are available. Specify when ordering.

Can contacts be mixed (power + signal) within the 18 positions?

Yes -- a common configuration uses 12 power contacts + 6 signal contacts. Custom mix arrangements are available; contact us with your circuit diagram.
