Understanding Penn-Union’s Terminal Plug Solutions & Applications

In the world of electrical systems, reliable connections are crucial for safety, efficiency, and performance. Penn-Union meets these demands with a range of specialized terminal plug solutions designed to excel in diverse industrial and utility environments. Whether handling aluminum conductors, managing space limitations, or connecting dissimilar metals, Penn-Union’s Aluminum Terminal Plugs, Aluminum Terminal Plug Offsets, and Bi-Metallic Terminal Plugs offer dependable, high-performance options.

These products also address installation applications where electrical conductors can often be oversized. Oversized conductors are often used in applications to address:

• Voltage drop concerns
• Safely handle current spikes
• Accommodate future expansion and increased loads
• Extreme temperature swings

Here’s a closer look at these products, their applications, and their unique benefits.

Aluminum Terminal Plug

Type: TP

Purpose: Permit use of stranded copper or aluminum conductors in equipment such as panel boards, meter sockets and mechanical connectors contained in molded case circuit breakers

Applications:

• Utility Systems: Widely used in substations, transmission lines, and distribution systems where aluminum conductors are present.
• Industrial Settings: Ideal for aluminum busbar systems and power distribution panels.
• Renewable Energy Projects: Found in solar farms and wind turbines, where lightweight aluminum conductors are essential.

Key Features:

• Manufactured from high-strength aluminum alloy, tin plated and filled with oxide inhibitor for a cool running compression connection.
• Solid plug has same diameter as current carrying equivalent copper wire permitting the use of larger aluminum wire to connect equipment.

Aluminum Terminal Plug Offset

Type: TPO

Purpose: Address challenges in installations with limited space or complex layouts while permitting use of stranded copper or aluminum conductors in equipment.

Applications:

• Panelboards and Switchgear: Crucial for precise alignment in compact setups.
• Complex Busbar Systems: Streamlines positioning in constrained environments.
• Utility and Industrial Systems: Simplifies installations with overlapping conductors.

Key Features:

• Retains all the benefits of standard aluminum terminal plugs, with a space-saving offset design.
• Reduces the need for extensive adjustments during installation.

Bi-Metallic Terminal Plug

Type: TPC

Purpose: Designed to facilitate the termination of aluminum, copper, and diesel locomotive conductors to a copper or aluminum/copper rated mechanical lug.

Applications:

• Utility and Substation Systems: Transitioning aluminum cables to copper busbars or equipment terminals.
• Industrial Installations: Ensuring compatibility between aluminum wiring and copper components.
• Renewable Energy Systems: Critical in setups with mixed-metal conductor materials, including solar and backup power systems.

Key Features:

• Barrel is pre-filled with oxide inhibitor to seal out moisture and minimize conductor oxidation.
• The entire connector is electro-tin plated for corrosion resistance.
• Body is manufactured from high strength aluminum alloy and the Pigtail is manufactured from high conductivity copper.
