Packing and Shipping
2000kVA Dry Type Transformer
The Packing and Shipping process for the NPC Electric 2000kVA Dry-Type Transformer is carefully designed to ensure the transformer is securely protected during transportation and arrives at its destination in optimal condition. Initially, the transformer undergoes a thorough inspection to verify that it is free from any manufacturing defects and is in full working order. Once inspected, the transformer is cleaned to remove any dust or debris that may have accumulated during the production process. The packing process then begins, where the transformer is carefully placed into a custom-designed, durable wooden crate or metal frame, which provides robust protection from external impact during transit. The crate or frame is reinforced with internal padding, such as foam, rubber inserts, or protective film, to cushion the transformer and prevent damage to sensitive components like bushings, terminals, and insulation.
The transformer is securely fastened within the crate or frame to prevent any movement during handling or transportation. To further enhance protection, the transformer may be wrapped in moisture-resistant plastic or shrink-wrapped to shield it from environmental elements such as humidity, dust, or dirt during shipment. It is clearly labeled with necessary shipping details, including model number, weight, handling instructions, and any other relevant information to ensure proper identification and careful handling during transport.
The packaging also includes all required shipping documentation, including customs clearance papers, inspection certificates, and safety data, especially for international shipments. This ensures compliance with local regulations and facilitates smooth customs processing. The transformer is then transported by the most suitable means, such as by road, sea, or rail, depending on the delivery location. Heavy-duty lifting equipment, such as cranes or forklifts, is used for loading and unloading to avoid any physical damage.
Upon arrival at the destination, the transformer is carefully unloaded and subjected to a final inspection to ensure that no damage occurred during shipping. Once verified, the transformer is ready for installation. The entire packing and shipping process guarantees that the NPC Electric 2000kVA Dry-Type Transformer arrives safely and is fully prepared for reliable operation in its intended application.

2000kVA Dry Type Transformer
Progress Test
NPC Electric manufactures high-quality three-phase dry-type transformers under strict quality control protocols. The Progress Test for the NPC Electric 2000kVA Dry-Type Transformer is an essential and thorough testing process designed to ensure that the transformer meets the highest standards of performance, safety, and reliability before it is commissioned for use. The testing begins with an insulation resistance test, where the transformer’s insulation system is subjected to high-voltage DC testing to confirm that it can withstand electrical stress and prevent leakage or breakdown, ensuring the safety and longevity of the transformer in operation. The next step is the winding resistance test, where the primary and secondary windings are tested for uniform resistance, ensuring there are no defects such as short circuits or open windings that could compromise the transformer’s functionality. The dielectric withstand test follows, in which the transformer is subjected to a voltage higher than its rated operating voltage to simulate potential voltage surges. This test verifies that the transformer’s insulation is strong enough to withstand overvoltage conditions without damage or failure.
Design Tests
All transformer will be test after finished the production, test items as below:
♦ Insulation Power Factor
♦ Winding Resistance
♦ Impulse Tests
♦ On load Loss Test
♦ No Load Loss Test
♦ Leak Test
♦ DC Insulation Resistance Test
♦ Transformer Turns Ratio/TTR (All Tap Voltages)
♦ Impedance Voltage & Load Loss (Rated Voltage)
♦ Excitation & No-Load Loss (Rated Voltage)
♦ Applied Voltage
♦ Induced Voltage
♦ Lightning Impulse
♦ Insulation Resistance (Rated Voltage)
♦ Temperature Rise
Transformer Factory Acceptance Test
NPC Electric conducts rigorous quality control testing on every transformer or representative samples, as well as on specific components and materials, to ensure compliance with design specifications throughout the production process.
The Factory Acceptance Test (FAT) for a 1000kVA three-phase dry-type transformer is a critical step performed before shipment to verify that the unit meets all applicable standards and delivers optimal performance. The FAT includes the following key procedures:
Visual Inspection: Evaluates the transformer’s physical condition, including the enclosure, terminals, and labeling, to ensure conformance with design and safety requirements.
Electrical Testing: Involves measuring winding resistance, insulation resistance, and performing turns ratio tests to validate electrical integrity and functionality.
Dielectric Strength Test: Applies high voltage across the insulation system to ensure it can endure both normal and transient operating voltages without failure.
Load Testing: Simulates real-world operating conditions to assess the transformer’s voltage regulation, temperature rise, and overall efficiency under load.
Protection Device Testing: Verifies the proper operation of integrated protective components such as thermal sensors, temperature relays, and tap changers (if applicable).
Routine Test - Leak Test
Purpose of Testing
The purpose of water leakage test is to check whether there is leakage in the equipment or system, to ensure that it has good sealing and safety during use. The integrity of the equipment can be verified by simulating the pressure or load conditions in the working environment.
Testing Equipment
Leakage current tester (e.g. Fluke, Hioki, Megger, etc.)
Voltage source (usually 500V, 1 KV or 2.5 KV, customized according to test requirements)
Temperature and humidity meter
Ground electrode

Check for leaks
Check for leaks on equipment surfaces and joints by using a foam detector, gas leak detector, or other suitable method.
Repeat Testing (if necessary)
If the test finds leakage or there is any doubt, repeat the test as necessary to verify the sealing of different locations or different equipment parts.
Evaluation Criteria (Reference)
No leakage (excellent): No leakage during the test, the equipment is completely sealed.
Minor leakage (good): Very small leakage is allowed, and it is necessary to judge whether it is qualified according to industry standards.
