Our factory is equipped with cutting-edge technology and staffed by experienced professionals, consistently producing high-quality products that have gained recognition in the international market. We look forward to establishing a lasting cooperative relationship with you and becoming your reliable partner in China. Our core product, the HYB New Energy American style unit substation, is an excellent power control system.
1.Intelligent Monitoring: Equipped with an intelligent monitoring unit that supports monitoring, protection, remote control, and video monitoring, fulfilling user requirements for remote management and real-time data tracking.
2.Environmentally Friendly: Utilizes vegetable oil (FR3) with a high ignition point (above 360°C) and a natural degradation rate of over 90%, offering better overload capacity compared to mineral oil transformers.
3.Strong Environmental Adaptability: Features an IP54 shell protection rating, multiple anti-corrosion designs, and a dehumidification scheme that combines heating dehumidifiers and axial flow fans, enabling it to operate effectively in harsh environments, including high humidity and heavy salt mist.
4.Excellent Electrical Performance: The short-term withstand parameters of the high-voltage vacuum circuit breaker can reach 31.5kA/4S, better accommodating the increasing capacity demands of customers for a single box transformer.
5.Innovative Structural Design: Includes a drainage device installed on top of the transformer box to prevent ice accumulation on blades, protecting both the box and the transformer radiator from damage.
