Safety and Reliability Best Practices for Medium Voltage Connections in Data Centers

As data centers continue to grow in scale and power density, medium voltage (MV) power distribution is becoming increasingly common. Compared with low voltage systems, MV connections allow higher transmission efficiency, reduced losses, and better scalability. However, they also introduce higher safety requirements and technical complexity.

However, MV systems also introduce higher electrical, thermal, and safety risks. This makes the selection of components — especially MV Mechanical connectors — critical to ensuring long-term safety, reliability, and operational continuity

To ensure stable operation, protect personnel, and minimize downtime, it is essential to follow best practices for safety and reliability when designing, installing, and maintaining medium voltage Mechanical connections in data centers.

This article outlines best practices for safe and reliable MV connections and highlights the role that JERA’s MV Connectors play in supporting these goals.

1. Using Certified and Proven MV Mechanical Connectors

One of the most important factors in MV system safety is the quality of connectors and terminations.

JERA’s MV Mechanical Connectors are:

• Manufactured in accordance with IEC and relevant international standards
• Type-tested for thermal cycling, short-circuit performance, and electrical endurance
• Designed to maintain low contact resistance over long service life

By using connectors that are fully tested and certified, data center operators significantly reduce the risk of overheating, insulation degradation, and unexpected failures.

2. Ensuring Installation Quality with Mechanical Reliability

Improper installation is a common cause of MV failures.

JERA’s MV mechanical connectors are engineered to:

• Provide consistent and repeatable contact pressure through controlled bolt designs
• Eliminate the need for crimping in many applications, reducing human error
• Enable faster, cleaner, and safer installation in confined data center environments

3. Supporting Insulation Integrity and Electrical Clearances

Maintaining insulation integrity is essential for preventing partial discharge and flashover.

JERA designs its MV Mechanical connectors with:

• Smooth geometric profiles that minimize electric field concentration
• Compatibility with heat-shrink and cold-shrink insulation systems
• Materials selected for high dielectric strength and tracking resistance

These features help ensure stable insulation performance even under high load and fluctuating environmental conditions.

4. Enhancing System Safety through Grounding and Shielding Compatibility

Safe grounding is essential in any MV installation.

JERA’s connector designs:

• Support proper bonding of cable screens and metallic components
• Ensure continuity of grounding paths across the connection point
• Are compatible with standard grounding and shielding practices used in data centers

This contributes to reduced touch voltage, improved fault current paths, and enhanced personnel safety.

5. Improving Reliability in Harsh or Controlled Environments

Even well-controlled data center environments experience thermal cycles and aging effects.

JERA’s MV Mechanical Connectors are tested for:

• Long-term thermal stability
• Resistance to humidity, corrosion, and vibration
• Mechanical integrity under repeated load changes
• This makes them suitable for both indoor switchrooms and outdoor substations connected to data center campuses.
