Product Profile
Built around a 1.5 MVA power block, the Apexto 1500 kVA Pad-Mounted Transformer is suited to facilities with substantial continuous loads, including mining infrastructure, data centers, and industrial distribution systems.
Compared with smaller 1.0–1.25 MVA units, it provides greater room for load variation, auxiliary equipment, and future expansion. The transformer can be configured for different utility voltages and low-voltage distribution systems, with loop or radial feed options available.
For projects where equipment operates around the clock, the 1500 kVA model offers a practical balance between capacity, thermal performance, and infrastructure scalability without moving immediately into the 2 MVA class.
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
How many amps does a 1500 kVA transformer provide at 480V?
About 1,804A at full load on a three-phase 480V system.
Is 1500 kVA enough for a 1.2 MW mining or data center load?
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.
Can a 1500 kVA transformer feed a 2000A switchboard?
Yes. A 1500 kVA, 480V transformer delivers about 1,804A, so a properly designed 2000A switchboard is a practical match.
How much real power can a 1500 kVA transformer support?
About 1,425 kW at 0.95 PF and up to 1,500 kW at unity power factor.
What primary voltages can Apexto configure for a 1500 kVA transformer?
Common options include 12.47kV, 13.2kV, 13.8kV, 24.94kV, and 34.5kV, with secondary voltage configured around the project.
Should I choose loop feed or radial feed?
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.
Can Apexto build 13.8kV to 480Y/277V?
Yes. 13.8kV to 480Y/277V is a common configuration for mining, data center, and industrial power distribution projects.
Can a new 1500 kVA transformer fit my existing concrete pad?
Often yes. Send us the existing nameplate, pad dimensions, cable-entry locations, and drawings so the enclosure layout can be checked before production.
What information does Apexto need before quoting?
Primary voltage, secondary voltage, total load, application, loop/radial feed, termination type, impedance/BIL requirements, and any existing utility or EPC specification.
