Package and Ship
45kva 11.95kv Three Phase Pad Mounted Transformer
NPC ELECTRIC three-phase transformers are designed to be securely packaged for sea freight transport, ensuring safe delivery across long distances. For this purpose, we offer wooden crate packaging that meets international shipping standards, protecting the transformer from potential damage during transit.
The sea freight wooden crates are made from high-quality, durable wood, treated to prevent moisture damage, corrosion, and pests. The crate is also reinforced to withstand the rigors of sea transport, offering superior protection from shocks and vibrations.
To enhance safety and security, the transformer is securely mounted inside the crate with anti-shift supports. This prevents any movement during transit, reducing the risk of mechanical damage. Additionally, the crate is equipped with strong, secure fastening systems to keep the transformer in place.
We ensure that all wooden crates are fully compliant with international shipping regulations, including ISPM 15 standards, to prevent any issues with customs and quarantine procedures. This makes our packaging solution both reliable and cost-effective for global shipments.
In addition to robust packaging, we provide comprehensive shipping insurance for every transformer. This insurance covers potential risks during transit, such as damage, theft, or natural disasters. By offering this coverage, we ensure peace of mind for our clients, knowing their valuable equipment is protected throughout its journey.
Whether shipping to overseas projects or international clients, our wooden crate packaging, coupled with shipping insurance, guarantees that your transformer arrives in perfect condition, ready for installation. With careful design and attention to detail, we prioritize the safety, security, and integrity of your equipment throughout the shipping process.

Raw Material Test
Before production begins, all raw materials used in the manufacturing of transformers undergo thorough testing. This ensures that every material, from copper wires to steel sheets, meets the highest industry standards. Our quality control team inspects material specifications, conducts tensile strength and conductivity tests, and checks for any potential contaminants or impurities. By carefully selecting and testing each component, we guarantee that only the best materials are used in the final product, ensuring durability, reliability, and high performance.
Active Part Test
Once the raw materials are processed into transformer components, the core body of the transformer is subjected to rigorous testing. This includes structural assessments to ensure correct assembly and proper alignment of internal parts. The core body is also tested for mechanical strength, resistance to heat, and electrical insulation properties. This phase checks for potential defects in the design or material properties, ensuring the transformer will perform efficiently even under extreme operational conditions.
FAT
After assembly, the final transformer undergoes a comprehensive series of tests to confirm its performance and safety. This includes electrical tests to verify voltage, current, and insulation resistance. We also perform temperature rise tests to ensure the transformer can operate under load without overheating. Additionally, safety tests such as overcurrent, short circuit, and dielectric tests are conducted to ensure the transformer meets all industry safety standards. Only after passing these stringent checks do we approve the finished product for delivery.
