A Power Transformer is a core component in electrical transmission and distribution systems, designed to efficiently step up or step down voltage levels to ensure safe, stable, and economical power delivery. It is widely used in utility substations, industrial facilities, infrastructure projects, and commercial power systems.
Lugao Power Co., Ltd. specializes in the design and manufacturing of Power Transformers, including Dry Type Transformers and Oil Immersed Transformers, providing reliable solutions for both indoor and outdoor power applications. With proven technology, strict quality control, and global project experience, Lugao transformers are trusted by customers worldwide.
Lugo offers two main types of power transformers for different applications: Dry-type power transformers, which use air and solid insulation instead of insulating oil; fireproof, non-polluting and environmentally friendly; suitable for indoor installations and load centers.
Oil-immersed power transformers, which use insulating oil for cooling and insulation; high efficiency and heat dissipation; suitable for outdoor substations and high capacity applications.
Regardless of transformer type, all Lugao Power Transformers share the following core strengths:
High-quality magnetic core design with low energy loss
Stable electrical performance and long service life
Strong short-circuit withstand capability
Compliance with international standards (IEC, GB, CE, CCC)
Strict factory testing before delivery
Customizable solutions based on project requirements
These shared features ensure that customers receive safe, efficient, and durable power equipment, regardless of the selected transformer type.
Choose Dry Type Transformers when fire safety, indoor installation, and environmental protection are priorities.
Choose Oil Immersed Transformers when higher capacity, outdoor installation, and cost efficiency are required.
