Packing and Shipping
100kVA Completely self-protected(CSP) Single Phase Pole Mounted Transformer
NPC ELECTRIC single-phase transformers are designed to be securely packaged for sea freight transport, ensuring safe delivery across long distances.
For this purpose, the packing of the 100kVA Completely Self-Protected (CSP) Single Phase Pole Mounted Transformer is a meticulous process aimed at safeguarding the product throughout its journey from the factory to the installation site.
The transformer is first enveloped in a high-grade anti-static and moisture-resistant plastic film. This film not only shields the transformer from moisture, which could cause corrosion and electrical malfunctions, but also prevents the accumulation of static electricity that might damage sensitive components. After that, a layer of soft, high-density foam padding is carefully wrapped around the transformer. This foam acts as a shock absorber, protecting the unit from impacts and vibrations during handling and transportation. Special attention is given to the protruding parts and vulnerable areas, where additional foam is added for extra protection.
The foam-wrapped transformer is then placed into a custom-fabricated wooden box. The interior of the box is lined with a layer of rubber or felt to further dampen vibrations. The box is designed to fit the transformer precisely, with custom-cut compartments and supports to hold the unit firmly in place. Reinforcing bars are installed on the corners and edges of the box to enhance its structural integrity and prevent it from being crushed or damaged.
On the exterior of the wooden box, clear and prominent labels are affixed. These labels include handling instructions such as "Fragile", "This Side Up", and "Keep Dry". Product information labels display details such as the transformer's model number, capacity (100kVA), weight, and dimensions. There are also warning signs indicating the presence of high-voltage components and safety precautions.
The choice of transport mode depends on the destination and delivery time requirements. For local or regional deliveries, trucks are typically used due to their flexibility and relatively short transit times. The trucks are equipped with shock-absorbing suspension systems to minimize vibrations during the journey. For long-distance or international shipments, a combination of sea freight and land transport may be employed. Sea freight is cost-effective for large and heavy items like transformers, while land transport is used for the final leg of the journey to the installation site.
During loading, the transformer is carefully lifted using appropriate lifting equipment such as cranes or forklifts. Once loaded onto the transport vehicle, the wooden box is secured using heavy-duty straps and chains. The straps are tightened to ensure that the box remains stable and does not shift during transit. Additional bracing materials may be used to further secure the box in place, especially in the case of rough roads or long-distance travel.
