What is the analog to concerntric palm shead bolt lug CAT-BLMC？

In low- and medium-voltage power networks, concentric palm shear bolt lugs are widely used for reliable mechanical and electrical connections. Among them, CAT-BLMC concentric palm shear bolt lug is a well-known model used by utilities and contractors.

What is CAT-BLMC Concentric Palm Shear Bolt Lug

The CAT-BLMC shear bolt lug is designed for aluminum and copper conductors, especially in LV and MV distribution systems. Its key features typically include:

• Concentric palm design for stable alignment and even current distribution
• Shear head bolts that break off at a predefined torque, ensuring correct installation without torque wrenches
• Wide conductor range, reducing inventory complexity
• Bimetal or aluminum body, suitable for different cable materials
• Compliance with IEC 61238-1 type test requirements

Because of these advantages, CAT-BLMC cable lug is commonly specified in utility projects. However, availability, lead time, or cost considerations often drive the need for equivalent products.

Why Look for an Analog to CAT-BLMC shear head lug?

There are several practical reasons why customers search for an analog or equivalent:

• Supply chain flexibility – avoiding dependency on a single brand
• Cost optimization – achieving similar performance at a more competitive price
• Local certification requirements – matching IEC or regional standards
• Project compatibility – replacing CAT-BLMC in tenders or technical specifications

An equivalent product must deliver the same mechanical strength, electrical performance, and installation reliability.

There are many factories and alternative products that serve as analogues to the concentric palm shear bolt lug CAT-BLMC in the market.
