Ergom KRA 35/8 Sealed Aluminum Cable Lug

The Ergom KRA 35/8 sealed aluminum cable lug is a professional-grade terminal engineered for the secure termination of aluminum conductors. Designed to maintain electrical integrity in demanding environments, this lug features a sealed construction that prevents oxidation and moisture ingress, ensuring long-term reliability for power distribution systems. Its robust aluminum build provides optimal conductivity and mechanical strength, making it a dependable choice for industrial and commercial electrical infrastructure.

Advantages

The primary benefit of the Ergom KRA 35/8 is its sealed design, which effectively isolates the conductor from external environmental factors that typically cause corrosion in aluminum connections. This protection maintains low contact resistance over the lifespan of the installation. Furthermore, the lug is specifically optimized for aluminum cabling, ensuring a precise fit that facilitates efficient current flow and reduces the risk of overheating at connection points. Its durable construction supports high-performance standards in various electrical setups.

Suitable for

• Industrial power distribution networks
• Commercial electrical installations
• Connecting aluminum power cables to busbars or equipment
• Outdoor electrical infrastructure requiring moisture protection

This cable lug may not be suitable for applications involving copper conductors without the use of appropriate bimetallic transition adapters, as direct contact between copper and aluminum can lead to galvanic corrosion. It is also not intended for use in high-vibration environments where specialized vibration-resistant terminals are required.

Key specifications

• Material: High-conductivity aluminum
• Design: Sealed type for environmental protection
• Conductor cross-section: 35 mm²
• Stud hole diameter: 8 mm

To use the Ergom KRA 35/8, first strip the insulation from the aluminum conductor to the appropriate length. Insert the conductor fully into the barrel of the lug. Use a professional hydraulic or mechanical crimping tool compatible with aluminum lugs to perform the crimp, ensuring the tool settings match the lug size. Once crimped, the connection can be bolted to the desired terminal point using the 8 mm stud hole.

What to consider before purchase

• Verify the cross-section of your aluminum cable matches the 35 mm² specification.
• Ensure the mounting stud size is compatible with the 8 mm hole diameter.
• Confirm the use of proper crimping dies designed for aluminum terminals.
• Check for compatibility if connecting to non-aluminum equipment surfaces.

For optimal performance and safety, always apply an appropriate contact grease to the aluminum conductor before crimping to prevent oxidation. Ensure that the crimping tool is calibrated and that the correct crimping sequence is followed according to industry standards for aluminum terminations.
