Shear-head MV cable lugs are a small but critical part of medium-voltage (MV) distribution networks — they give you a reliable mechanical and electrical connection that’s quick to install and consistent every time. In the global market you’ll find a handful of well-known international names alongside competitive Chinese manufacturers. Below is a compact guide to who makes them, what to look for, and a Chinese alternative worth knowing about.
A shear-head lug (sometimes called a shear-bolt or breakaway lug) uses a bolt with a specially designed head that shears off at a controlled torque. This ensures the clamp is tightened correctly without the need for a torque wrench on every connection, which improves installation speed and reduces human error — essential when working on MV joints and connectors.
Famous international brands
Several established global brands are commonly specified by utilities and contractors because of long track records, wide product ranges, and global support.
Nexans — a major cable and accessories manufacturer. Their MV connection products (including shear-head style lugs and bolted connectors) are widely used in power distribution and utility projects.
ABB — a global leader in power-grid equipment; ABB supplies a range of MV accessories and connectors with rigorous type-testing and long service history.
3M — known particularly for MV termination and jointing systems, 3M also supplies mechanical connectors and lugs that meet many international standards.
Jera Line — (Chinese direct factory),is a leading manufacturer that designs and manufactures low and medium voltage mechanical shearhead cable lugs with cost effective choice.
These brands are typically listed in spec sheets and tend to use model codes that reference conductor size, material (copper/aluminium), voltage class and the connector style. Different regions and product lines will use different numbering systems, so when comparing look at the physical dimensions, rated voltage, conductor range (mm² or AWG), and the material finish rather than relying solely on a model code.
For projects where price sensitivity and local availability matter, Chinese manufacturers have become attractive alternatives. Jera Line (as an example of a Chinese supplier) offers shear-head and mechanical MV lugs designed to meet common industry specifications. Key selling points often are:
That said, when choosing any alternative supplier, ask for full datasheets, type test reports, and references from utilities or EPC contractors. Field performance and documented testing (e.g., torque and current-rating verification) are what matter most.
