Purpose: Protection of aluminum wire contacts against oxidation
Capacity: 35.3 g
Application: For connecting aluminum wires and joining aluminum and copper wires
Type: Contact paste
Color: Grayish

Functions

Protection of aluminum wires against oxidation – the paste removes and reduces the formation of oxide layers on the surface of aluminum conductors, ensuring better electrical conductivity.

Connection of copper and aluminum wires – allows safe connection of conductors made from different metals in one connector, reducing the risk of electrochemical corrosion.

Lower contact resistance – improves contact quality and reduces energy losses at connection points.

Longer connection service life – protects connections from aging, corrosion, and overheating risks.

Reliable electrical contact – helps ensure stable and long-term transmission of electrical current even after many years of operation.

Applications

For homeowners: Suitable for renovating old electrical installations in apartments, houses, or garden buildings where aluminum wiring is still used. Allows safe connection of new copper wires to existing installations.

For electrical installers: Helps perform aluminum wire connection work quickly and professionally while reducing the risk of future contact issues.

For electricians and maintenance specialists: Used for repairing, modernizing, and maintaining electrical networks in industrial and commercial facilities.

For engineers and designers: Recommended for projects where existing aluminum installations are retained or modernized in stages.

For apartment building renovation projects: One of the most effective solutions when new electrical lines must be connected to old aluminum wiring without replacing the entire installation.

FAQ

Can copper and aluminum wires be connected using this paste?

Yes. WAGO ALU-PLUS is specifically designed to allow safer and more reliable connection of aluminum and copper wires in the same connector.

Is it necessary to use paste with aluminum wires?

It is recommended. Aluminum oxidizes much faster than copper, so the paste helps maintain good contact and reduces the risk of overheating.

Does the paste protect against corrosion?

Yes. It helps reduce oxidation and corrosion at contact points, ensuring the connection remains reliable for a longer period.

Where is this paste most commonly used?

It is most commonly used during the renovation of electrical installations in older apartment buildings, private houses, administrative buildings, and industrial facilities where aluminum wiring is still present.
