Future of Data Center Power: MV Connectors and 400V DC Integration

As data centers continue to scale rapidly to support cloud computing, artificial intelligence, and high-performance workloads, power infrastructure is under increasing pressure to become more efficient, reliable, and scalable. Traditional low-voltage AC architectures are reaching their practical limits in terms of efficiency, space utilization, and operational complexity.

Against this background, the combination of medium voltage (MV) power distribution and 400V DC integration is emerging as a future-oriented solution for modern and next-generation data centers.

1. The Power Challenge in Modern Data Centers

Power density in data centers is rising quickly. AI clusters, GPU racks, and high-performance computing systems demand far more power per rack than traditional IT equipment. This creates challenges in three key areas:

• Transmission efficiency over long distances inside large facilities
• Space and material consumption of copper cables and switchgear
• Reliability and fault tolerance of complex multi-stage power architectures

To address these issues, operators are rethinking how power is delivered from the utility grid to the IT rack.

2. Why Medium Voltage Distribution Makes Sense

Medium voltage distribution allows power to be transmitted over longer distances with lower current and reduced losses. Compared to traditional low-voltage distribution, MV systems offer:

• Lower I²R losses and improved energy efficiency
• Smaller conductor sizes and reduced copper usage
• Better scalability for large campuses and hyperscale data centers

MV systems also reduce the number of transformation stages required, simplifying system architecture and improving overall reliability.

However, MV systems require highly reliable and safe connection technology, which makes MV mechanical torque connectors connectors a critical component in ensuring system stability.

3. The Role of MV mechanical torque Connectors

MV mechanical torque connectors provide the mechanical and electrical interface between cables, switchgear, transformers, and power distribution equipment. In data center environments, these connectors must meet strict requirements for:

• Electrical insulation and partial discharge control
• Mechanical stability and vibration resistance
• Thermal performance under continuous high load
• Safety for installation and maintenance personnel

High-quality MV terminal connectors enable fast installation, modular system design, and high operational reliability, making them essential for modern MV-based power architectures.
