Trend:

Development trend

As China continues to vigorously promote high efficiency, energy saving and environmental protection in all walks of life, the development of environmentally friendly and energy-saving three-phase isolation transformers has become the direction that domestic enterprises need to work hard. Specifically, the development trends of three-phase isolation transformers have the following four points:

More green and environmentally friendly

Environmental protection is the general trend. As energy shortages and environmental pollution intensify, major manufacturers have set their next development goals on energy conservation and environmental protection. The same is true for three-phase isolation transformers. Energy conservation and environmental protection are an eternal issue. Issues such as how to make products have lower losses, higher energy efficiency, lower noise, and less use of non-renewable materials are worthy of further research and exploration. The development and introduction of new materials and new processes will make future three-phase isolation transformers more energy-saving and quieter in operation.

High safety factor

The number of three-phase isolation transformers produced in our country has reached tens of millions, and they are used in major key projects and operate in many fields such as technology, medical care, and production. Especially during the peak power consumption season in summer, higher requirements are put forward for the safety of transformers. We conduct controls at all stages including design, production, process, and quality inspection to ensure that the power equipment is foolproof. In the future, three-phase isolation transformers will undergo further reliability certification in terms of safety, and power safety will be the unremitting goal of designers and manufacturers.
