In order to ensure that the transformer is not affected by the external environment during long-distance transportation, it is usually packed in sturdy wooden boxes or wooden pallets. A waterproof film is added to the outside of the wooden box to prevent water vapor from entering and protect the transformer from moisture. The wooden box structure usually uses imported high-quality wood to ensure strength and stability. The transformer is additionally protected against shock by foam, airbags or rubber pads inside the wooden box to reduce possible collisions and vibrations during transportation.
The transformer is fixed in the container by steel wire ropes, wooden frames, support blocks, etc. to prevent sliding or tilting during transportation. Especially during the shaking of sea voyage, it is necessary to ensure that the transformer is stable and motionless to avoid damage. Sea transportation usually involves long-term sea transportation, especially in humid and salt spray environments. To prevent the equipment housing and internal components from being corroded by salt, an anti-salt spray coating is added to the outside of the packaging box, and preservatives are used to ensure the safety of the transformer during sea transportation. During transportation, products are usually insured with full marine insurance to ensure full compensation in case of damage or loss.
The packaging and shipping process of NPC ELECTRIC'S 167kVA Conventional Type Single Phase Pole Mounted transformer involves multiple details, including sturdy wooden box packaging, moisture and corrosion protection, precise loading and fixing, temperature and humidity monitoring during sea transportation, and customs clearance and delivery procedures after arriving at the destination.

Purpose of Testing
The purpose of the transformer turns ratio (TTR) test is to confirm whether the voltage ratio between each tap of the transformer meets the design requirements and ensure that the transformer winding is connected correctly. By measuring the voltage ratio of each tap, it is possible to detect whether there is a fault or deviation in the transformer winding.
Testing Equipment
TTR tester: such as Doble, Megger, Omicron and other brands of transformer winding ratio tester.
Voltage source: usually AC 10 V to 30 V , used to test different voltages for each tap.
Temperature and humidity meter: used to record environmental conditions during the test to ensure test accuracy.
Current probe: used to measure the load current of the winding and ensure the accuracy of the test results.
