ZGSL-Z-3150/25-0.415
Our 25kV pad-mounted transformer (Model: ZGSL-Z-3150/25-0.415) is a heavy-duty, purpose-built power distribution solution engineered for reliable medium-to-low voltage conversion in demanding outdoor environments. With a 3150kVA rated capacity, 25kV primary voltage, and 415Y/240V secondary voltage, this 3150kVA pad-mounted transformer delivers consistent performance for large-scale power networks. Built with a fully sealed corrosion-resistant steel enclosure and IP55 protection rating, it is optimized for long-term operation in extreme weather, high-humidity, and high-pollution settings, supported by an efficient ONAN cooling system that limits full-load temperature rise to 65K.
Our low-loss pad-mounted transformer achieves a verified 99.16% full-load efficiency, with no-load loss ≤3.2kW and load loss ≤23.5kW—outperforming standard industry units by 30% to deliver significant long-term energy savings for high-demand operations.
Engineered to withstand harsh outdoor conditions, the unit resists weather ingress, vandalism, and wildlife interference, with a rugged build that supports a 30-40 year service life with proper maintenance. It has passed rigorous type tests including lightning impulse and short-circuit withstand tests.
Ground-level mounting simplifies installation, requiring only a concrete pad and standard electrical connections. The accessible design streamlines routine inspections, minimizing downtime and lowering long-term operational expenses.
The tamper-proof, lockable steel enclosure prevents unauthorized access, with built-in grounding and fault protection that meets strict safety requirements for high-traffic commercial and industrial sites.
