Optional Configurations

5kVA Conventional Type Single Phase pole Mounted Transformer
The optional specifications of NPC electric's 5kVA Conventional Type Single Phase pole Mounted transformer are usually customized according to the user's specific needs or application scenarios. These optional specifications can provide flexible configurations under different power environments, installation conditions or special needs to improve the performance and adaptability of the transformer.​
Users can choose different insulation levels according to the environmental conditions of the region (such as temperature and humidity). Common insulation levels include Class A (105°C), Class B (130°C) and Class F (155°C). Providing a higher insulation level can improve the heat resistance of the transformer, thereby adapting to higher temperatures or more severe working environments.​
Depending on the installation location, users can choose different housing materials, such as aluminum alloy, stainless steel or hot-dip galvanized steel plate to enhance corrosion resistance. IP level (protection level) can be selected such as IP23, IP54 or higher, providing stronger waterproof and dustproof protection, suitable for harsh outdoor environments.​
Some transformers can provide load regulation function, allowing users to adjust the output voltage as needed to adapt to grid load fluctuations or ensure stable power supply. And to prevent the transformer from being damaged due to overload or overheating, you can choose to install an automatic temperature control protector, which can automatically disconnect the power supply when the temperature is too high to protect the transformer from damage.​
These optional specifications provide additional flexibility for the 5kVA conventional single-phase pole-mount transformer, enabling it to be customized according to different environmental conditions, working needs and safety requirements. These configurations help improve the performance, reliability and adaptability of the transformer to meet the needs of specific industries, regions or customers.

Packing and Shipping

5kVA Conventional Type Single Phase pole Mounted Transformer
The packaging and transportation of 5kVA Conventional Type Single Phase pole Mounted transformer is an important step to ensure that the transformers are not damaged during transportation and are delivered to customers on time and safely.
The transformers are first wrapped with moisture-proof and dust-proof materials to protect the equipment from the external environment. Commonly used packaging materials include plastic film, foam padding, and anti-rust paper. The transformers are usually placed in sturdy wooden boxes or steel frames to provide additional physical protection from collisions or vibrations during transportation.
According to the weight and size of the transformer, choose the appropriate transportation tools (such as trucks, containers, etc.) for loading. According to customer requirements and destinations, transformers can be transported by land, sea or air. For international transportation, customs declaration and export procedures may be required.
The transformers are firmly fixed in the transport vehicle or container to prevent displacement or vibration during transportation. Tie straps, wooden pallets and other fixings are usually used to ensure the stability of the equipment.
In the container, the transformer is usually placed on a dedicated bracket to reduce pressure and friction on the equipment.
Through careful packaging and shipping arrangements, the 5kVA conventional single-phase pole-mount transformer can remain safe and intact during transportation, ensuring that customers receive quality equipment to meet their power needs.

Progress Test

Progress Test

The process testing of 5kVA Conventional Type Single Phase pole Mounted transformer is an important step to ensure that the product meets the standards at every stage of the production process. Before the production starts, all raw materials are strictly checked, especially in terms of the windings and insulation materials of the transformer. The windings of the transformer are electrically tested to check parameters such as the resistance of the windings and the insulation resistance. After the transformer is assembled, a load test is performed. By fully verifying the various performance of the transformer (such as output voltage, load capacity, efficiency, etc.), it is ensured that it meets all technical requirements and user needs.

FAQ From Customers

What is a Transformer?
A transformer is an electrical device used to change the voltage of alternating current (AC). It works on the principle of electromagnetic induction, converting high-voltage current into low-voltage current or low-voltage current into high-voltage current. Transformers are widely used in power transmission, distribution systems, and various electronic devices.
What are the main uses of a transformer?
The main use of a transformer is voltage conversion. Transformers are used in power transmission systems to help transfer electricity from power plants to consumers. In addition, transformers are also used in electronic devices such as chargers, televisions, power adapters, etc., to adjust the voltage to meet the requirements of different devices.
Do you have UL listed?
Yes, our transformer has UL listed. We have exported to America many pad mounted transformer,substation transformer and HV.
