Packing and Shipping of 250kVA Oil Immersed Transformer
For this purpose, the packaging and transportation of 250kVA three-phase oil-immersed transformers are important links to ensure the safe and intact delivery of equipment, including the following:
Packing
- Main body protection: The transformer body is first cleaned to remove surface impurities and oil stains. Then it is wrapped with moisture-proof and rust-proof plastic film to prevent rust caused by moisture erosion during transportation. Then, the key parts of the transformer, such as radiators, oil pillows, gas relays, etc., are individually wrapped and fixed with cushioning materials such as foam and sponge to reduce damage caused by collision and vibration.
- Accessory packaging: For transformer accessories, such as thermometers, oil level gauges, desiccant, valves, etc., special plastic boxes or wooden boxes are used for packaging. Soft cushioning materials are filled in the packaging to ensure that the accessories do not collide with each other during transportation. At the same time, each accessory is numbered and marked, and a detailed list is attached to facilitate users in checking during installation.
- Overall packing: The wrapped transformer body and the packaged accessories are packed together in a special large wooden box or metal box. The box should have sufficient strength and rigidity to withstand various external forces during transportation. Fixing devices are set in the box to firmly fix the transformer body to the bottom of the box to prevent shaking and displacement during transportation. In addition, obvious signs such as "upward", "fragile", "moisture-proof", and so on are marked on the surface of the box to remind the transportation personnel to pay attention to the correct handling and storage methods.
Transportation
Transportation method selection: Choose the appropriate transportation method according to the transportation distance, transportation conditions, and customer requirements.
For short-distance transportation, road transportation can be used, and large trucks can be used for loading; for long-distance transportation, railway transportation or water transportation can be considered to reduce transportation costs.
When choosing a transportation method, it is necessary to ensure that the transportation vehicle has sufficient carrying capacity and stability to ensure the safe transportation of the transformer.
Applications of 250kVA Three Phase Liquid-Immersed Transformer
Industrial Production: Suitable for power supply of factories, workshops and production lines, ensuring normal operation of electrical equipment.
Power Grid Construction: Used for voltage transformation in distribution networks, connecting high-voltage and low-voltage power systems.
Commercial & Residential Areas: Applicable to commercial buildings, shopping malls, hotels and residential communities, providing reliable power for daily use and air conditioning systems.
Special Scenarios: Customizable for mining, railways, renewable energy power generation and other special fields.
