Barrel Length

20 mm to 60 mm, providing extra crimping surface for secure conductor retention

Termination Type

Single-hole stud design; stud sizes from 6 mm (M6) to 16 mm (M16) for robust bolting

Crimping Compatibility

Compatible with hexagonal, indent, or circular crimping tools; hydraulic tools recommended

Operating Temperature Range

-55°C to 150°C, maintaining conductivity under thermal stress

Surface Finish

Bare copper or tin-plated options, enhancing corrosion resistance and contact reliability

Voltage Rating

800 N to 4000 N, ensuring superior mechanical stability due to longer barrel

Tensile Strength

500 N to 3000 N, ensuring mechanical stability post-crimping

Environmental Resistance

IP54 rating; resists oxidation and moisture in controlled indoor/outdoor environments

Standards Compliance

Conforms to IEC 61238-1, UL 486A-486B, and RoHS for safety and performance

Installation Method

Crimp-on only; designed for heavy-duty crimping tools

Conductor Compatibility

Supports stranded or solid copper conductors (Class B to Class K), ideal for larger wires

Technical Advantages

Power delivery needs lugs that maximize strength and handle stress effectively. Our Long-Barrel Copper Lugs offer tensile strength from 800 N to 4000 N and operate from -55°C to 150°C, ensuring effective performance to meet your requirements. 

Loose joints can lead to system failures and downtime. These lugs feature barrel lengths from 20 mm to 60 mm and corrosion-resistant options, maintaining stability to support your operational needs.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does your long barrel improve connection strength in my systems?

The extended barrel, ranging from 20 mm to 60 mm, provides more crimping surface for a tighter grip on conductors. This increases tensile strength up to 4000 N, reducing the chance of loosening under vibration or load. As a result, your systems get more reliable power delivery.

What makes Frigate’s lugs suitable for larger wires in my setup?

These lugs handle conductor sizes from 2.5 mm² to 400 mm², ideal for bigger wires in heavy-duty applications. Their design supports stranded or solid copper conductors, ensuring a secure fit without strain. Thus, they work well for high-power equipment like motors or generators.

How do your lugs hold up under high current demands

They manage currents from 50 A to 1200 A, keeping performance steady even at peak loads. Plus, the high-conductivity copper maintains efficiency, minimizing heat buildup during operation. So, you avoid power drops in demanding manufacturing lines. 

Are your lugs a good fit for outdoor or tough environments?

With an IP54 rating, they resist moisture and oxidation in controlled outdoor settings. However, their bare copper or tin-plated options add flexibility for harsher conditions if needed. This means they stay functional where standard lugs might wear out. 

Why invest in long-barrel lugs over shorter alternatives?

Short-barrel lugs may cost less, but they offer weaker holds for larger wires or high-stress uses. In contrast, the longer barrel boosts stability and durability, cutting risks of failure over time. Therefore, you save on repairs and replacements in the long run.
