As hyperscale and enterprise data centers continue growing in power density, electrical infrastructure reliability has become more critical than ever. Medium-voltage (MV) distribution systems play a central role in supporting uninterrupted operations for servers, cooling equipment, UPS systems, and backup power networks.
In these high-load environments, cable connection quality directly affects system safety, efficiency, and uptime. That is why many datacenter installers are increasingly choosing shear-head bolt terminals for medium-voltage cable connections.
Jera Line manufactures a range of MV shear-head bolt terminals designed for fast installation, reliable conductivity, and long-term performance in mission-critical power systems.
Shear-head bolt terminals, also called mechanical shear torque lugs, are used to terminate medium-voltage cables without requiring hydraulic crimping tools. Instead of compression technology, the terminal uses specially designed shear bolts that tighten onto the conductor until the bolt head breaks off at the correct torque.
This ensures:
Data centers demand electrical systems capable of handling high current loads continuously. Any weak cable connection can lead to overheating, voltage drop, or unexpected shutdowns.
Shear-head bolt terminals are especially suitable for datacenter environments because they provide:
Construction timelines for modern data centers are often aggressive. Mechanical shear-head terminals reduce installation time by only a hex tool.
The shear-head mechanism automatically achieves the required tightening force. Once the designed torque level is reached, the bolt head shears off, this helps stable performance.
For mission-critical facilities operating 24/7, consistent connection quality is essential.
Modern data centers use a variety of MV cable dimensions depending on load requirements and system architecture. Shear-head terminals simplify inventory management because a single connector can often accommodate a cable range rather than one exact conductor size.
Jera Line Mechanical shear bolt lugs are engineered for medium-voltage cable systems used in utilities, industrial facilities, and datacenter infrastructure.
Designed for medium-voltage cable termination applications. The terminal uses shear-off-head bolts to achieve reliable conductor tightening without requiring compression tools.
Key features include:
High-current datacenter circuits generate significant thermal stress over long operating periods. Poor compression quality or insufficient torque can create hotspots that eventually damage insulation and cable conductors.
Shear-head terminals help minimize these risks through:
This contributes to better long-term reliability and lower maintenance requirements for critical power infrastructure.
