At ZHNYU ELECTRIC, we combine 34 years of manufacturing expertise with a dedication to innovation, resulting in fused isolators that set the benchmark for safety and performance. Our production facility, spanning 10,000 square meters and equipped with over 100 advanced machines, enables us to achieve precision engineering at scale. Each fused isolator undergoes a meticulous production process, beginning with high-grade materials selection. We use silver alloy contacts to ensure excellent conductivity and resistance to arc erosion, and our housings are constructed from glass-reinforced polyamide, offering high mechanical strength and fire resistance (UL94 V-0).
