Product Details
A 30 kVA transformer is a small-capacity electrical equipment. It can transmit and step electricity in the circuit. It can be used in homes, companies and factories where stable electricity supply is needed. The term “30 kVA” actually means the rated apparent power of transformers. kVA is the abbreviation of kilovolt – ampere. It is used to measure the maximum electrical load the transformer can bear.
30 kVA Dry-type Transformer
Our 30 kVA dry-type transformer uses air to cool down, not oil. This type of transformer is especially designed for indoor installation and concentrates on fire prevention and low cost maintenance. The transformer is environmentally friendly and doesn’t have the the risk of oil leakage or pollution. Typical applications include commercial buildings, hospitals, schools, data centers, and factories. These places require clean, safe, and reliable power. As a leading 30 kVA transformer manufacturer, we ensure that each dry-type transformer delivers high efficiency, low noise, and long service life.
30 kVA Isolation Transformer
Our 30 kVA isolation transformers provide electrical isolation between primary and secondary circuits. This is helpful to protect our equipment from power surges, light lightning and electrical noise, which can help make the electrical supply stable and secure. These transformers are commonly used in medical equipment, CNC machines, UPS systems and audio systems.They are ideal in situations where voltage stability and safety are critical. Our isolation transformers meet international standards. They offer high insulation resistance and excellent load voltage regulation.
30 kVA 3-phase Transformer
The 30 kVA 3-phase transformer is designed for industrial and commercial power distribution systems. It efficiently transfers power between different voltage levels while maintaining balanced load performance across all three phases. It is ideal for workshops, factories and small and commercial facilities. These sites require reliable three-phase power for motors, pumps, and production equipment.
30 kVA Step-down Transformer
A 30 kVA step down transformer is used to reduce voltage from a higher level to a lower level (for example,our 3-phase oil-immersed 30 kva transformer steps down voltage from 6-11 kV to 400V). This makes it suitable for low-voltage equipment and distribution panels. It ensures safe operation, protects connected devices, and improves energy efficiency in commercial and industrial systems. There are two phase-types of step-down transformers: single-phase and three-phase. They are widely used in workshops, warehouses and commercial electrical systems.
30 kVA Step-up Transformer
The 30 kVA step up transformers can raise voltage levels from a lower level to a higher level, which can support the equipment that are designed to operate at higher voltage levels. They are commonly used in renewable energy systems, machinery export and localized power distribution projects. In those scenarios, we need higher voltage levels to to transmit electricity efficiently. Our step-up transformers use high quality iron core materials and and precise winding techniques. The design can help reduce energy loss and maintain stable voltage output.

Environmental factors that may affect applications
The transformer operate reliably in ambient temperatures from -15°C to +40°C. For places with higher temperatures, we offer optional enhanced insulation or special cooling systems.
Standard models can work well 1000 meters above sea level. For higher altitudes, we can customize transformers to keep cooling and insulation working properly.
For humid or dusty places like coastal places or mining areas, we recommend cast resin dry-type transformer or sealed transformers. They help prevent corrosion and dust pollution.
