10 Kva Pad Mount Transformer 13200y/7620 Grounded Wye Primary 240/120v Secondary ONAN
Product Overview
The 10 KVA Single-Phase Pad Mount Transformer is a compliant, high-performance power distribution solution engineered for 13200Y/7620V Grounded Wye Primary and 240/120V Secondary output. Filled with non-PCB mineral oil (ASTM D3487 compliant) and equipped with ONAN cooling, it delivers reliable voltage stepping-down for residential, light commercial, and utility applications.
Product parameters and images are for general reference only and may not reflect all details of your custom configuration, due to custom builds and minor variations between standard models. Precise specifications for your order are detailed in the specification table and supporting technical documents (CAD files, dimensional drawings, wiring diagrams, etc.). Specific details may differ from images. Please review all specifications and technical documents before ordering; do not rely solely on product images. We offer custom-built units with lead times nearly as fast as prebuilt models --contact us for your specific requirements.
Key Features
Optimized Voltage Configuration: 13200Y/7620V Grounded Wye Primary (4-wire multi-grounded neutral) is tailored for North American medium-voltage grids, supporting standalone single-phase use or three-phase bank setups for flexible utility integration.
Low-Maintenance Cooling & Insulation: Non-PCB mineral oil (ASTM D3487 compliant) provides superior dielectric strength and heat dissipation; ONAN natural cooling eliminates fans/pumps, reducing failure points and operational costs.
Durable Outdoor Design: Weatherproof NEMA 3R cabinet with corrosion-resistant coating and sealed oil tank protects against moisture, dust, and harsh weather, suitable for direct outdoor concrete pad installation without fencing.
High Compliance & Safety: Meets ANSI, IEEE, NEMA, and DOE 2016 efficiency standards; 95kV primary/30kV secondary BIL ratings resist voltage surges, while grounded wye design enhances fault protection.
Versatile Compatibility: Tin-plated bronze terminals work with both copper and aluminum wiring, simplifying installation and retrofits in existing distribution systems.
Applications
Residential Districts: Powers single-family homes, townhouses, and small apartment complexes, delivering stable 240/120V power for daily lighting, appliances, and household equipment.
Light Commercial Spaces: Supports small businesses, retail stores, offices, and community centers, accommodating mixed 120V/240V loads with reliable performance.
Utility Grid Upgrades: Ideal for replacing aging transformers in North American medium-voltage grids, improving efficiency and compliance with modern industry standards.
Urban/Suburban Distribution: Compatible with both overhead lines and underground cables, offering an unobtrusive solution for areas where overhead poles are impractical.
Rural Service Points: Durable design withstands extreme temperatures (-40℃ to +55℃), making it suitable for rural utility distribution with minimal maintenance needs.

Frequently Asked Questions
Q: Can this transformer be used in both overhead and underground distribution systems?
A: Yes. Its pad-mounted design and sealed, weatherproof cabinet make it suitable for outdoor concrete pad installation, compatible with both overhead medium-voltage lines and underground power cables. It requires no protective fencing, making it ideal for urban areas where overhead poles are impractical or unobtrusive underground systems are preferred.
Q: What makes the 13200Y/7620 Grounded Wye Primary configuration unique for this transformer?
A: The 13200Y/7620 Grounded Wye Primary is a standardized 4-wire multi-grounded neutral configuration widely used in North American medium-voltage grids. It supports both single-phase standalone use (connected to one phase and neutral of a 13200Y system) and three-phase bank setups, offering enhanced fault protection and voltage balance--critical for stable power delivery to end-users, unlike lower-voltage primary configurations.
