>> Product Introduction
The ZGSL-Z-1500-13.8-0.415 is a radial feed pad-mounted transformer designed for underground power distribution networks. It steps down 13.8kV primary voltage to 0.415kV secondary voltage, delivering 1500kVA capacity for commercial and industrial applications.
Housed in a locked, weatherproof steel enclosure, this electrical transformer ensures safe operation in compact spaces without requiring fenced enclosures. Key features include:
✔ High-efficiency design (up to 98.5% energy efficiency)
✔ Radial feed configuration for simplified underground cable connections
✔ Corrosion-resistant construction for outdoor durability
Ideal for utility service drops, this pad-mounted transformer provides reliable power conversion while meeting IEEE and IEC standards.
Product Advantage
As a leading transformer manufacturer, our ZGSL-Z-1500-13.8-0.415 radial feed pad mounted transformer delivers exceptional performance for modern power distribution networks. This electrical transformer converts 13.8kV to 0.415kV with 1500kVA capacity, offering:
1.Superior Cost Efficiency (vs Loop Feed)
The radial feed design reduces infrastructure costs by ~25% with simpler cabling requirements. Our transformer factory achieves this while maintaining 98.5% efficiency (3.2kW no-load/18.5kW load losses) - verified by ISO 9001-certified testing.
2.Compact & Space-Saving Design
Measuring just 2.1×1.8×1.9m, this pad mounted transformer fits space-constrained sites. The radial configuration eliminates complex switching gear, saving 35% footprint versus loop feed alternatives.
3.Reliability and durability
Constructed to withstand harsh environmental conditions, pad mounted transformers boast a robust design, contributing to their long service life. They resist weather elements, vandalism, and wildlife interference, ensuring consistent and reliable power distribution over time.
4.Ease of installation and maintenance
The ground-level placement of pad mounted transformers simplifies the installation process, requiring only a concrete pad and electrical connections. This accessibility also makes routine maintenance and inspections more straightforward, reducing operational costs and less downtime.
5.Enhanced security
The lockable enclosures of pad mounted transformers provide an additional layer of security, protecting against unauthorized access and tampering. This is particularly important in areas susceptible to vandalism or where public safety is a concern.

>> Product Uses
1. Radial Feed Pad-Mounted Transformer Applications
Residential Subdivisions: Ideal for housing developments with single-source power feeds.
Small Commercial Buildings: Suitable for retail stores, offices, and schools where redundancy is not critical.
Rural Electrification: Used in remote areas with simple grid layouts.
Temporary Power Supply: Deployed for construction sites or emergency power restoration.
Advantages of Radial Feed:
✔ Lower Installation Cost (25-30% savings vs. loop feed)
✔ Simpler Design (Single power input reduces cabling complexity)
✔ Faster Commissioning (Can be installed in 6-8 hours)
✔ Easier Maintenance (Fewer components to inspect)
2. Loop Feed Pad-Mounted Transformer Applications
Urban Grids & Smart Cities: Used in networked distribution systems requiring high reliability.
Industrial Parks: Ensures uninterrupted power for factories and manufacturing plants.
Critical Facilities: Hospitals, data centers, and airports where power redundancy is essential.
Renewable Energy Integration: Supports microgrids with multiple power sources.
When to Choose Loop Feed?
✔ Need automatic backup power (N-1 redundancy)
✔ Require minimal downtime during maintenance
✔ Operating in high-load, complex grids
