Medium Voltage bolted Connectors :The Backbone of Modern Data Center Power

As global demand for cloud computing, AI processing, and high-density storage continues to surge, data centers have become the beating heart of the digital economy. Behind their seamless operation lies one critical component that often goes unnoticed yet plays a decisive role in ensuring power reliability and safety—medium voltage (MV) bolted connectors.

The Role of MV Connectors in Grid Integration

Medium voltage bolted connectors act as the primary interface between incoming utility supply and the internal distribution network of the data center. Key functions include:

• Safe and secure cable termination

Preventing overheating, arcing, and mechanical stress during high-load operation.

• Reliable power continuity

Ensuring uninterrupted electricity flow to servers, cooling systems, UPS, and critical equipment.

• Scalability for future expansion

Allowing data centers to add capacity without redesigning the entire electrical infrastructure.

• Compatibility with diverse MV equipment

Including switchgear, ring main units (RMU), transformers, and distribution cabinets.

Typical MV bolted connection solutions used in Data Centers include:

• Shear-off cable lugs and connectors

Designed for consistent torque application and long-term performance.

• Insulated MV cable terminations (cold-shrink or heat-shrink)

Providing environmental protection and electrical insulation.

• MV branch connectors and T-body connectors

Widely used in compact switchgear and underground cable systems.

• Transition connectors

Used when different conductor materials or cable sizes need to be joined.

These components are engineered to withstand harsh environmental conditions, mechanical stress, and high-fault currents—ensuring long-term reliability.

Challenges MV Bolted Connectors Solve for Data Centers

• High load demands

MV connectors prevent overheating under constant high-current operation.

• Space constraints

Many modern designs are compact, making them ideal for dense MV rooms.

• Safety regulations

Connectors built to IEC/IEEE standards help facilities meet strict global compliance requirements.

• Downtime prevention

Stable MV connections greatly reduce the risk of unexpected power failure—a critical KPI for data center operators.
