Product Description

15kva-250kva Single Phase Power Distribution Pad Mounted Transformer

Our design philosophy for Pad Transformer

♥ Pad-mounted transformers are ground-mounted distribution transformers enclosed in metal cabinets, typically located on a concrete pad.
♥ Enclosed in a grounded metal box with all contacts live, this transformer can be installed in residential areas without fences, unlike transformers in substations.
♥ MPS's pad-mounted transformers are tamper-proof and weatherproof, so they can be safely placed where people are present. All enclosures are made of heavy gauge steel and are powder-coated for tamper-proof features. Our pad-mounted transformers are available in live and non-live designs, as well as radial or loop feed.
♥ Made of high-quality materials, our transformers typically support residential, commercial, and industrial loads in urban and rural areas. They are filled with sustainable and biodegradable dielectric fluids for excellent fire resistance and longer service life.

♥♥Design Products for Customer Needs♥♥

Yixin Electric Power Equipment has more than 50 engineering and technical personnel, more than 1000 employees, covering an area of 240, 000 square meters. Whether in terms of design talent or production experience, our company is one of your best choices.

Product Description

★Design and Engineering

• Specification Development: The process begins with understanding the customer's requirements, including the desired voltage, capacity, and environmental conditions.
• Electrical Design: Engineers design the electrical aspects, including the core, windings, insulation, and cooling system.
• Mechanical Design: Simultaneously, mechanical aspects like the enclosure, tank, and mounting features are designed to ensure they can withstand environmental and operational stresses.

★Material Selection and Procurement
Due to our rich experience in production and manufacturing for power transformer, we have a wealth of selection advantages and price advantages in the selection of raw materials and suppliers. The quality and price of the products are advantages for us.

• Core Material: Grain-oriented electrical steel is typically selected for the transformer core due to its high magnetic permeability.
• Copper/Aluminum Windings: High-conductivity copper or aluminum is chosen for the windings.
• Insulation Materials: Insulating paper, pressboard, and varnishes are selected based on their dielectric properties.
• Tank and Enclosure: The materials for the tank and enclosure (usually steel) are selected for durability and corrosion resistance

★Core Construction
In order to assure the implementation ofthe advance design and manufactural tech-nology,some key equipments,moulds andtools had been repleced,moulds andimprovedwith the new technologies to meetthe requrements of product quality.

• Core Cutting: The steel sheets are cut into specific shapes and sizes according to the design.
• Core Assembly: These sheets are stacked together to form the transformer core, usually in a step-lap formation to minimize losses.

★Winding Process

• Winding Design: The windings are designed based on the voltage and current requirements.
• Winding Construction: The copper or aluminum wires are wound around the core using precision machines to create the primary and secondary windings.
• Insulation: Each layer of winding is insulated to prevent short circuits and ensure proper electrical isolation.

★Assembly

• Core and Coil Assembly: The windings are placed around the core, and the entire assembly is secured in place.
• Tank Assembly: The core-coil assembly is placed into the transformer tank, and connections are made for input and output terminals.
• Filling with Insulating Fluid: The tank is filled with an insulating fluid, typically mineral oil, to provide cooling and electrical insulation.

★Vacuum Drying

   The transformer is placed in a vacuum oven to remove any moisture trapped in the insulation and the insulating fluid. This step is crucial for ensuring the longevity and reliability of the transformer.


★Sealing and Painting

• Sealing: After vacuum drying, the tank is sealed to prevent any leakage of insulating fluid.
• Painting: The exterior of the transformer is painted to protect it from environmental factors like moisture, dust, and UV radiation.

★Testing

• Electrical Testing: The transformer undergoes various electrical tests, including voltage tests, insulation resistance tests, and short-circuit tests, to ensure it meets all specifications and standards.
• Leakage Testing: The transformer is checked for any leaks in the tank or bushings.
• Final Inspection: A thorough final inspection is conducted to ensure all components are properly assembled and functioning.
• Transformer ratio and connection
  Measurement of load losses and short circuit impedance.
  Measurement of no-load losses.
  Separate source withstand voltage test
  Induced over-voltage test
  Temperature rise test
  Lighting impulse withstand voltage test
  Measurement of partial discharge
  Other transformers like rectifier transformer are also available on request.

★Quality Assurance
   A quality control team reviews all test data and inspections to ensure the transformer meets all regulatory and customer-specific requirements.

★Packaging and Shipping

• Packaging: The transformer is carefully packaged to prevent damage during transport.
• Shipping: It is then shipped to the customer or the installation site.
