Compression lugs are a necessary part of terminating electrical conductors and are common in telecommunications, welding and power distribution equipment, among many other applications. They provide a connection point to the device circuit with a stud-type input power connection.
Burndy® is a leading manufacturer of compression lugs that are designed specifically for each type of cable. For instance, flexible cables use different lugs than non-flexible cables because the copper strands settle differently when the insulation is stripped off.
At WesBell Electronics, we carry a variety of Burndy compression lugs for whatever your work entails, along with crimping tools that work well with Burndy products.
Types of Burndy Compression Lugs
Lugs can be long or short and have one or two holes, with each characteristic offering different benefits:
- One-hole lugs: Good for standard use, one-hole lugs leave room for a tightening bolt. They can be rated anywhere from 600 volts to 35,000 volts with UL and CSA approvals. Size options cover American Wire Gauge (AWG) 6 through 500 thousands of circular mils (MCM).
- Two-hole lugs: These lugs have two bolts to keep the lug in place and are necessary for larger vibrating machinery. They also maintain tighter connections. Two-hole lugs include UL and CSA approvals, are rated from 600-35,000 volts and come in AWG 6-500 MCM sizes.
- Long-barrel lugs: A long-barrel lug has a crimp that attaches to more of the cable, offering greater security. The cable can be pulled around more, but it must be crimped twice. It also helps the lug last longer by withstanding more vibration. These lugs are available in the same sizes as the above one- and two-hole lugs.
- Short-barrel lugs: Short barrels are more basic and only use one crimp for the wire.
Once you choose the type of lug you need, you’ll need to decide the hole size and AWG size based on the size of your electrical cable.
All of our compression lugs from Burndy are made of flexible, highly conductive copper and feature approvals from CSA, UL and the Restriction of Hazardous Substances (RoHS) directive. They offer maximum conductivity with low resistance and ductility. Identification is simple, as these connectors include the wire size and type, die index, color-coding and locations for crimping. They’re built with heavy-duty wall thickness, internally beveled barrel ends and electro-tin plating for corrosion resistance.
Burndy designs compression lugs that support reliable, well-controlled electrical connections. They run cooler than the installed wire and can withstand a variety of electrical and environmental conditions, like current surges, high temperatures and vibrations. All of that comes from affordable builds that provide cost-effective installation.
Additional Tools for Cable Crimping
To install cables in a compression lug, you’ll need crimping tools, which we also source from Burndy. Be sure to check out our Burndy crimping tools to ensure you have everything you need for your cable projects.
