FAQs of 30KW Isolation transformer with three phase 220V to 380V:
Q: How does the 30KW Isolation Transformer improve safety in industrial power systems?
A: The transformer provides electrical isolation between the primary and secondary circuits, reducing the risk of electrical shock and equipment damage caused by surges or ground loops. Its robust insulation and high dielectric strength offer added protection.Q: What are the main benefits of using a step-up transformer from 220V to 380V in manufacturing environments?
A: This step-up transformer enables machinery that requires 380V operation to function efficiently even when only 220V power is available. It ensures reliable voltage conversion with high efficiency (98%), improves power distribution, and supports a wide range of industrial applications.Q: When should floor-mounted transformers like this model be chosen over wall-mounted alternatives?
A: Floor-mounted designs are ideal for heavy-duty industrial use where transformers weigh more (approx. 150 kg) and require robust support. They also allow easier installation and maintenance access in large electrical rooms or manufacturing plants.Q: What process is involved in installing and connecting this transformer?
A: Installation involves securely positioning the transformer on the floor, connecting it to the power supply via busbar terminals, and ensuring correct wiring between 220V (input) and 380V (output) phases. Regular checks of mounting, insulation, and ventilation are recommended.Q: Where can this 30KW Isolation Transformer be used most effectively?
A: It is most effective in industrial settings such as factories, workshops, and plants requiring reliable voltage conversion, electrical isolation, and compatibility with international standards. Typical applications include machinery operation, voltage boosting, and uninterrupted power supply.Q: How does natural air ventilation support the cooling of this transformer?
A: Natural air ventilation cools the transformer without the need for external fans or liquid coolants, using ambient airflow to dissipate heat generated during operation. This ensures consistent performance in temperature ranges from -20C to +45C.Q: What are the advantages of the copper and silicon steel construction?
A: High-purity copper winding ensures top electrical conductivity, reducing energy losses, while the silicon steel core minimizes magnetic losses and optimizes efficiency. This combination results in durable, low-maintenance, and high-performance transformer operation.Tell us about your requirement
