Packing and Shipping
10kVA Conventional Type Single Phase Pole Mounted Transformer
The packaging and shipping process of NPC ELECTRIC'S 10kVA Conventional Type Single Phase pole Mounted transformer is crucial to ensure that the product is safe and intact during transportation and can cope with the special environment of sea transportation (such as salt spray, moisture, vibration, etc.).
The core components of the transformer (such as oil tank, windings, electrical connections) need to be professionally protected. First, we will wrap the vulnerable parts of the transformer with soft shockproof materials (such as foam, plastic protective film) to avoid impact and friction during transportation.
The transformer is placed in a reinforced wooden box or wooden pallet to ensure that the product is stable and easy to load and unload. The wooden box can be protected by multiple layers of shockproof foam pads, wooden pads and soft pads. The outside of the package will be marked with product information, operating requirements and shipping labels such as "fragile" and "waterproof". Anti-corrosion coatings will be used in the packaging materials, especially in environments with high humidity and salt spray, to ensure that the packaging materials will not corrode due to weather reasons.
The transformer will be firmly fixed in the container using wooden brackets or steel support frames to prevent severe vibrations during sea transportation. To prevent bumps and vibrations during transportation, the transformer will be firmly locked in the container.
In order to prevent potential risks during transportation, we will purchase transportation insurance for the transformer, including marine transportation insurance, fire insurance, theft insurance, etc., to ensure that compensation can be obtained in time in case of accidents. During the packaging and shipping of NPC ELECTRIC'S 10kVA Conventional Type Single Phase pole Mounted transformer, special attention is paid to the safety, integrity and timely delivery of the product. Through carefully designed internal and external packaging, professional transportation arrangements and strict loading and unloading processes, we ensure that the product can reach the hands of customers in the best condition.
