As a dedicated manufacturer with a strong presence in global markets from North America to Southeast Asia, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our reliable 7.2kV Class Pole Mount Transformer. Engineered for the demanding conditions of rural electrification, this 250kVA oil-filled transformer is built to deliver consistent and safe power distribution, helping utilities and contractors expand and stabilize electrical grids in remote areas. Our commitment to quality manufacturing processes ensures this transformer offers exceptional durability and performance, making it a cost-effective solution for long-term infrastructure projects.
This transformer is designed with a focus on operational efficiency and ease of installation in rural settings. Its core features and specifications are detailed below:
- Robust Construction for Harsh Environments: The tank is constructed from high-quality, corrosion-resistant steel, providing excellent mechanical strength and protection against environmental factors like moisture, dust, and temperature fluctuations common in rural areas.
- Efficient Oil Immersion Cooling: Utilizing mineral oil as both an insulating and cooling medium, the transformer ensures optimal thermal management, leading to a longer operational lifespan and reduced risk of overheating under variable loads.
- Pole-Mounted Design for Space Saving: The compact and sturdy pole-mounted design minimizes the need for expensive land acquisition and foundation work, allowing for quick deployment along existing utility pole lines.
- Customizable Configurations: We understand that project requirements can vary. Therefore, we offer options for primary and secondary voltage taps, choice of winding material (copper or aluminum), and the inclusion of protective devices like lightning arresters and fuse cutouts, available upon request.
- Low Losses for Energy Savings: The core and winding designs are optimized to minimize no-load and load losses, contributing to lower overall energy costs for the distribution network operator over the transformer's lifetime.
Key technical specifications for the standard model are summarized in the following table:
| Parameter | Specification |
|---|---|
| Rated Capacity | 250 kVA |
| High Voltage (Primary) | 7.2 kV |
| Low Voltage (Secondary) | 400Y/230 V or as required |
| Frequency | 50 Hz / 60 Hz |
| Vector Group | Dyn11 or as required |
| Noise Level | ≤ 55 dB(A) |
| Impedance Voltage | Approx. 4% (standard) |
| Temperature Rise | 65K (Oil), 70K (Winding) |
| Cooling Method | ONAN (Oil Natural Air Natural) |
The advantages of choosing this transformer extend beyond its basic specifications. It provides tangible benefits for your projects:
- Enhanced Grid Reliability: Stable voltage transformation reduces fluctuations, improving power quality for end-users in rural communities.
- Reduced Maintenance Needs: The sealed tank design and high-quality components minimize the need for frequent inspections and servicing, lowering total cost of ownership.
- Scalability for Future Growth: The design allows for integration into expanding networks, supporting future increases in power demand without requiring immediate replacement.

Frequently Asked Questions (FAQ)
-
What is the typical delivery lead time for this transformer?
Standard models typically have a lead time of 4-6 weeks. For customized configurations, the timeline may vary based on the specific requirements. We provide accurate delivery estimates upon order confirmation. -
Can this transformer be used in areas with extreme temperatures?
Yes, it is designed for a wide ambient temperature range. The mineral oil and insulation materials are selected to perform reliably in both high and low-temperature environments commonly found in rural areas. -
What are the installation requirements for this pole-mounted unit?
Installation requires a suitably rated utility pole and standard pole mounting hardware. We provide detailed installation manuals, and our technical team is available for consultation to ensure proper setup. -
Is copper or aluminum winding better for my application?
Copper windings generally offer higher efficiency and slightly better overload capacity but come at a higher initial cost. Aluminum windings provide a cost-effective solution with reliable performance for standard applications. We can advise based on your budget and technical priorities. -
What kind of routine maintenance is required?
Routine maintenance primarily involves periodic visual inspections, checking oil levels, and ensuring bushings and connections are clean and secure. The sealed tank design significantly reduces maintenance frequency compared to some other types. -
Do you offer after-sales support and spare parts?
Yes, we provide comprehensive after-sales support. A range of common spare parts such as gaskets, bushings, and pressure relief devices are available. Our support team can assist with troubleshooting if needed. -
Can the transformer be configured for different secondary voltages?
Absolutely. While 400Y/230V is standard for many regions, we can manufacture units with various low-voltage outputs (e.g., 480V, 240/120V) to match local grid standards upon request. -
What packaging is used for export shipment?
For export, the transformer is securely packed in a wooden crate with waterproof and shock-absorbing materials to ensure it arrives in perfect condition. We ship from major ports like Shanghai, Tianjin, Guangzhou, and Ningbo.
