Product Profile
The Apexto 1500 kVA (1.5 MVA) Three-Phase Pad-Mounted Transformer delivers reliable, continuous power for high-density compute infrastructure. Supporting up to ~1.2 MW of electrical throughput, it is the ideal capacity match for standard 20-foot hydro-cooled crypto mining containers and mission-critical data center facilities.
Compatible with standard utility feeds like 13.8kV and 34.5kV, it steps down to dedicated 415Y/240V, 480Y/277V, or 600V outputs, with full custom voltage engineering available for any grid. Fully UL/cUL certified and DOE energy-efficient, it prevents thermal tripping under 24/7 full load, minimizes power losses, and guarantees hassle-free utility inspection approval on day one.
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. Standard Monitoring Gauges
Equipped with precision liquid level, oil temperature, and pressure/vacuum gauges alongside an automatic pressure relief valve (PRV) for real-time operational safety.
03. Multi-Tier Fuse & Tap Protection
Features Bay-O-Net fuses paired with backup current-limiting fuses and a multi-position tap changer, providing instant fault isolation and seamless voltage regulation.
04. Low-Loss Core & Windings
Built with high-grade grain-oriented silicon steel cores and precision-wound coils, delivering ultra-low electrical losses and superior short-circuit withstand capacity.
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. Heavy-Duty C5-M Enclosure
Housed in a rugged, weather-sealed steel enclosure with advanced C5-M anti-corrosion coating and robust cooling radiators, engineered for harsh outdoor environments.

FAQs
About 1,804A at full load on a three-phase 480V system.
Yes, in many cases. At 0.95 PF, 1.2 MW equals about 1,263 kVA, leaving useful capacity for operating margin and auxiliary loads.
Common options include 12.47kV, 13.2kV, 13.8kV, 24.94kV, and 34.5kV, with secondary voltage configured around the project.
Radial feed works well for a simple dedicated transformer. Loop feed is better for multi-transformer sites, future expansion, or more flexible medium-voltage distribution.
Yes. 13.8kV to 480Y/277V is a common configuration for mining, data center, and industrial power distribution projects.
Often yes. Send us the existing nameplate, pad dimensions, cable-entry locations, and drawings so the enclosure layout can be checked before production.
