Duraline Ship to Shore Power: Multi-Gang Cam Lok Connector Systems for High-Current Applications

When naval vessels dock for maintenance, resupply, or extended port stays, they require massive amounts of reliable electrical power delivered safely from shore installations. For over 50 years, Duraline’s Ship to Shore Power Multi-Gang Cam Lok Connector Systems and single pole housings have been the original preferred standard for Navy bases, commercial shipyards, and industrial power distribution applications where high-current, vibration-resistant connections are mission-critical.

The Duraline Cam Lok Advantage

At the heart of Duraline’s ship-to-shore power solutions is the innovative Cam Lok connector design—a positive latching system that combines high conductivity, tool-free operation, and splash-tight performance in demanding marine and industrial environments.

Unique Latching Mechanism

Duraline Cam Lok connectors achieve secure, high-pressure connections through a proprietary latching design that sets them apart from conventional industrial connectors:

• High locking pressures ensure maximum contact and conductivity
• Tool-free connection and disconnection—no wrenches or special equipment required
• Insulated external release button for quick, safe unlocking
• No external metal parts reducing shock hazards and corrosion points
• Vibration-resistant design that won’t loosen during vessel operations or heavy equipment use

This combination means faster, safer connections for personnel while maintaining the electrical integrity required for high-current power distribution.

Ball-Nose Design and Splash-Tight Sealing

The ball-nose insulating sleeve design creates a splash-tight seal between male and female contacts, providing critical protection in wet marine environments where exposure to rain, spray, and humidity is constant. This feature is essential for pier-side installations exposed to weather and the corrosive saltwater environment of naval facilities.

Color-Coded Phase Identification

Insulators are available in multiple colors for easy phase identification, reducing connection errors and improving safety during high-voltage installations where proper phasing is critical to equipment protection and personnel safety.

Multi-Gang Block Configurations: Custom Solutions for Complex Power Needs

Duraline’s multi-gang systems allow any multiple of single-pole Cam-Type connectors to be molded into blocks and ganged together to form phase banks tailored to specific power distribution requirements.

Flexible Construction Options

Multi-gang blocks can be configured with:

• Direct cable molding to DLO cable for permanent installations
• Stud terminals for bolt-on lug connections
• Tapped holes for threaded lug attachment
• Machined aluminum plates for structural integrity and heat dissipation
• 30-degree angled housings for easier connection access and rain drainage away from contacts

Protection Options

Assemblies are available with:

• Rubber caps for flexible, weather-resistant protection
• Aluminum snap covers for durable, rigid shielding of unused connections
