As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing reliable and efficient electrical distribution equipment, including our Oil Filled 250kVA 7.2kV CSP Single Phase Pole Mount Transformer with a 120V/240V secondary. Our commitment to quality, backed by a comprehensive ISO management system framework, ensures that each transformer is engineered for durability, safety, and optimal performance in diverse power distribution networks. With over a decade of experience and a global reach spanning North America, Southeast Asia, Africa, and beyond, we understand the critical need for robust infrastructure components that minimize downtime and operational costs.
This transformer is designed to be a cornerstone of your electrical distribution system, converting higher primary voltages to usable secondary levels for residential, commercial, and light industrial applications. Its pole-mounted design makes it ideal for overhead distribution lines, offering a practical solution for utilities and contractors.
Key Features and Technical Specifications:
- CSP (Completely Self-Protecting) Design: Integrates protective features such as internal fuses or protective links, enhancing safety by reducing the risk of external faults affecting the transformer and the network.
- Oil-Filled Cooling System: Mineral oil serves as both an insulating and cooling medium, ensuring efficient heat dissipation and stable operation under varying load conditions, contributing to a longer service life.
- High-Efficiency Core and Coil: Utilizes high-grade magnetic steel and precision-wound copper or aluminum coils to minimize energy losses (core and winding losses), improving overall system efficiency.
- Robust Tank Construction: The welded steel tank is designed for mechanical strength and corrosion resistance, suitable for outdoor exposure in various climates.
- Pole Mount Compatibility: Engineered with mounting brackets and a compact form factor for secure installation on standard distribution poles, simplifying field deployment.
- Flexible Secondary Output: The 120V/240V secondary configuration is versatile, supporting common North American residential and commercial voltage requirements for lighting, appliances, and machinery.

Frequently Asked Questions (FAQ):
-
What does "CSP" mean in this transformer model?
CSP stands for "Completely Self-Protecting." It indicates that the transformer includes integrated protective devices, such as internal fuses or protective links, which help isolate faults and protect both the transformer and the connected distribution system from damage. -
Is this transformer suitable for both 50 Hz and 60 Hz power systems?
The standard design is typically for 60 Hz systems, common in North America. However, as a manufacturer with global export capabilities, we can customize the transformer to operate efficiently at 50 Hz for markets in Europe, Asia, and other regions. -
What are the installation requirements for this pole mount transformer?
It requires a sturdy distribution pole that meets local utility standards. Our unit comes with mounting brackets and clear installation guidelines. Proper grounding and connection to primary and secondary lines by qualified personnel are essential. -
How is the oil maintenance handled? Does it require regular replacement?
The oil-filled system is typically sealed and designed for long-term operation. Under normal conditions, the oil does not require routine replacement. Periodic testing for dielectric strength and moisture content may be recommended as part of a broader maintenance schedule. -
Can the secondary voltage be configured differently, such as 240V only?
Yes. While the standard offering provides a 120V/240V split secondary, we can customize the winding configuration to deliver a single 240V output or other voltages upon request to match specific project needs. -
What certifications or standards does this transformer comply with?
Our manufacturing processes are guided by a robust quality management system. The transformer can be designed and tested to meet common industry standards such as ANSI C57.12.00 or IEEE standards. Specific certification details are available upon request. -
What is the typical delivery lead time for this product?
Lead times vary based on order volume and customization requirements. For standard configurations, we aim for efficient production and shipment from our major ports like Shanghai, Tianjin, Guangzhou, or Ningbo. -
Does the transformer come with accessories like bushings or lightning arresters?
Standard bushings are included. Additional accessories such lightning arresters, protective covers, or specific connector types can be provided as optional items or customized based on your project specifications.
