Shear-Head Bolt Terminals: A Reliable Solution for High-Vibration Wind Turbine Connections

Wind turbines operate in one of the most mechanically demanding environments in modern power systems. Constant vibration, cyclic loading, temperature variation, and offshore corrosion challenges all place extreme stress on electrical connections. In such conditions, connection reliability is not optional—it is critical for safety, uptime, and long-term performance.

This is where shear-head bolt terminals (shear bolt cable lugs and connectors) have become a preferred solution for wind power applications.

What Are Mechanical Shear Bolt Terminals?

Mechanical shear-bolt terminals are mechanical electrical connectors that use torque-controlled shear bolts to clamp conductors securely inside the connector body.

During installation, the bolts are tightened until the head shears off at a predefined torque. This ensures:

• Consistent contact pressure
• No over- or under-tightening
• Reliable electrical conductivity

They are widely used for both:

• Power cable termination (lugs)
• Cable-to-cable connection (connectors)

Jera Line provides a wide range of MV mechanical shear head connectors and lugs designed for medium-voltage power distribution systems, including overhead lines, underground cable networks, and renewable energy installations such as wind and solar power plants.
