Product Profile
Engineered as the gold standard for high-density computing, the Apexto 2550 kVA (2.5 MVA) Three-Phase Pad-Mounted Transformer delivers ~2.0 MW of continuous electrical throughput, purpose-built to power 40-foot hydro-cooled crypto mining containers and enterprise data center facilities.
Stepping down standard 13.8kV, 34.5kV, or 24.94kV utility feeds to dedicated 415V, 480V, or 600V circuits, it supports custom tap configurations. Fully UL/cUL certified and DOE compliant, it ensures seamless utility grid interconnection.
Constructed with a heavy-gauge welded steel tank and stainless steel hardware, the weather-sealed enclosure features a UV-resistant electrostatic Munsell Green finish. Engineered for 20+ years of outdoor service, it delivers superior protection against corrosion and desert dust.
Core Advantages
01. Dead-Front Dual Compartment
Features a dual-compartment design separating high and low voltage with a rigid steel barrier. Enclosed dead-front bushings ensure maximum touch safety and tamper protection.
02. Multi-Tier Fuse & Switch Bay
Integrates accessible Bay-O-Net fuses with a four-position load-break switch (Source A/B) and a tap changer, ensuring instant fault isolation and safe power transfer.
03. Comprehensive Gauge Suite
Equipped with precision dial thermometer, pressure/vacuum, and oil level gauges alongside an automatic pressure relief valve (PRV) for continuous operational safety.
04. Auxiliary Control Cabinet
Houses neatly organized DIN-rail circuit breakers, terminal blocks, a power supply, and convenience outlet, simplifying secondary control wiring and field testing.
05. High-Conductivity LV Busbars
Fitted with heavy-duty tin-plated NEMA spade terminals (X0–X3) designed for high current capacity, minimizing contact resistance and easing multi-cable connections.
06. C5-M Enclosure & Cooling Fans
Protected by a C5-M marine-grade steel enclosure with large cooling radiator banks and auxiliary forced-air fans, engineered for non-stop duty in harsh environments.

FAQs
A 2550 kVA transformer is designed for larger power blocks where a standard 1000–2000 kVA transformer may limit future expansion. It provides higher power density while reducing the number of transformer units required for large deployments.
It depends on the site design. A single 2550 kVA transformer can simplify medium-voltage distribution and reduce the number of primary connections.
Multiple smaller transformers may provide more flexibility for phased deployment or redundancy.
A 2550 kVA transformer is suitable for large mining power blocks, including multiple container deployments or high-density hydro cooling systems.
The actual number of miners depends on miner model, operating power, cooling method, and auxiliary equipment load.
A 2550 kVA transformer provides additional capacity for projects that are approaching the practical limit of a 2000 kVA system or expect future load growth.
It allows more room for additional mining containers, cooling equipment, or electrical expansion without replacing the main transformer.
Yes. Large mining and data center projects often reserve transformer capacity for future growth.
Apexto evaluates current load, planned expansion, cooling infrastructure, and site layout when selecting transformer capacity.
Yes. The transformer can be configured according to project requirements, including utility voltage, secondary voltage, connection type, protection requirements, and installation conditions.
Yes. A 2550 kVA transformer can serve as a centralized power source for multiple mining containers or hydro cooling systems, helping create a scalable power infrastructure for larger sites.
