    Tips: Development Trend of Three Phase Isolation Transformer

    • Greener. Environmental protection is the general trend, with the shortage of energy and the aggravation of environmental pollution, major manufacturers have locked in the next development goal of energy conservation and environmental protection. Three-phase isolation transformer is also the same, energy conservation and environmental protection is an eternal subject. The development and introduction of new materials and new technology will make the future three-phase isolation transformer more energy saving, more quiet operation.
    • High safety factor. Three phase isolation transformer is used in major projects, such as science and technology, medical treatment, production and other fields. Especially in summer peak season, higher requirements for transformer safety are put forward. In the future, three-phase isolation transformer will be further reliability certification in terms of safety, and power safety will be the goal of unremitting efforts.
    • Scaling. As the population expands, so does the demand for electricity. The most obvious problem of power shortage is the peak consumption in summer and winter. Expanding capacity is the fundamental solution.
