CNKUANGYA&#8217;s complete portfolio of both AC and DC SPDs means customers can standardize on a single manufacturer for all surge protection needs\u2014from traditional power distribution to cutting-edge solar and EV applications. This consolidation reduces procurement complexity, simplifies inventory management, and ensures consistent quality across all protection devices.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. \u062c\u0648\u062f\u0629 \u0645\u0646 \u0627\u0644\u062f\u0631\u062c\u0629 \u0627\u0644\u0627\u062d\u062a\u0631\u0627\u0641\u064a\u0629 \u0648\u0628\u0623\u0633\u0639\u0627\u0631 \u062a\u0646\u0627\u0641\u0633\u064a\u0629<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CNKUANGYA has optimized their manufacturing processes and supply chain to deliver professional-grade surge protection at price points that make comprehensive protection accessible to a broader range of customers. This doesn&#8217;t mean cheap or compromised products\u2014it means efficient manufacturing, strategic sourcing, and a business model focused on volume and customer satisfaction rather than premium pricing. Every CNKUANGYA SPD undergoes rigorous testing and carries appropriate certifications, ensuring that cost savings never come at the expense of safety or reliability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. \u0627\u0644\u062f\u0639\u0645 \u0627\u0644\u0641\u0646\u064a \u0648\u0625\u0631\u0634\u0627\u062f\u0627\u062a \u0627\u0644\u062a\u0631\u0643\u064a\u0628<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u062a\u064f\u0638\u0647\u0631 \u0643\u0627\u0631\u062b\u0629 \u0645\u0646\u0634\u0623\u0629 \u0642\u0648\u0627\u0646\u063a\u062a\u0634\u0648 \u0623\u0646\u0647 \u062d\u062a\u0649 \u0623\u0641\u0636\u0644 \u0623\u062c\u0647\u0632\u0629 \u0627\u0644\u062d\u0645\u0627\u064a\u0629 \u0645\u0646 \u0627\u0644\u0635\u062f\u0645\u0627\u062a \u0627\u0644\u0643\u0647\u0631\u0628\u0627\u0626\u064a\u0629 \u0644\u0627 \u0642\u064a\u0645\u0629 \u0644\u0647\u0627 \u0625\u0630\u0627 \u062a\u0645 \u062a\u0631\u0643\u064a\u0628\u0647\u0627 \u0628\u0634\u0643\u0644 \u063a\u064a\u0631 \u0635\u062d\u064a\u062d. \u062a\u0648\u0641\u0631 \u0634\u0631\u0643\u0629 CNKUANGYA \u0648\u062b\u0627\u0626\u0642 \u0641\u0646\u064a\u0629 \u0634\u0627\u0645\u0644\u0629 \u0628\u0644\u063a\u0627\u062a \u0645\u062a\u0639\u062f\u062f\u0629\u060c \u0648\u0628\u0631\u0627\u0645\u062c \u062a\u062f\u0631\u064a\u0628 \u0639\u0644\u0649 \u0627\u0644\u062a\u0631\u0643\u064a\u0628\u060c \u0648\u062f\u0639\u0645 \u0641\u0646\u064a \u0633\u0631\u064a\u0639 \u0627\u0644\u0627\u0633\u062a\u062c\u0627\u0628\u0629 \u0644\u0636\u0645\u0627\u0646 \u062a\u062d\u0642\u064a\u0642 \u0627\u0644\u0639\u0645\u0644\u0627\u0621 \u0644\u0644\u062d\u0645\u0627\u064a\u0629 \u0627\u0644\u0645\u062b\u0644\u0649. \u064a\u0645\u062a\u062f \u0647\u0630\u0627 \u0627\u0644\u0627\u0644\u062a\u0632\u0627\u0645 \u0628\u0646\u062c\u0627\u062d \u0627\u0644\u0639\u0645\u064a\u0644 \u0625\u0644\u0649 \u0645\u0627 \u0628\u0639\u062f \u0627\u0644\u0628\u064a\u0639\u060c \u0645\u0639 \u0627\u0644\u062f\u0639\u0645 \u0627\u0644\u0645\u0633\u062a\u0645\u0631 \u0644\u0627\u0633\u062a\u0643\u0634\u0627\u0641 \u0627\u0644\u0623\u062e\u0637\u0627\u0621 \u0648\u0625\u0635\u0644\u0627\u062d\u0647\u0627 \u0648\u062a\u0631\u0642\u064a\u0627\u062a \u0627\u0644\u0646\u0638\u0627\u0645 \u0648\u062a\u062d\u0633\u064a\u0646 \u0627\u0633\u062a\u0631\u0627\u062a\u064a\u062c\u064a\u0629 \u0627\u0644\u062d\u0645\u0627\u064a\u0629.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4. \u0627\u0644\u0627\u0628\u062a\u0643\u0627\u0631 \u0627\u0644\u0645\u0633\u062a\u0645\u0631 \u0648\u062a\u0637\u0648\u064a\u0631 \u0627\u0644\u0645\u0646\u062a\u062c\u0627\u062a<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CNKUANGYA invests consistently in research and development to stay ahead of evolving surge protection requirements.

the difference between Type 1, Type 2, and Type 3 SPDs, and which do I need?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SPDs are classified into three types based on their intended installation location and the surge threats they&#8217;re designed to handle. Understanding these classifications is essential for implementing effective surge protection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u0627\u0644\u0646\u0648\u0639 1 SPDs \u0645\u0646 \u0627\u0644\u0646\u0648\u0639 1<\/strong> (also called Class I) install at the service entrance where utility power enters your facility. These robust devices are designed to handle direct lightning strikes and the most severe surge events, with surge current ratings typically from 50kA to 100kA per phase. Type 1 SPDs use voltage-switching technology (spark gaps) or hybrid designs that can safely conduct extremely high surge currents. They&#8217;re essential for buildings with external lightning protection systems (lightning rods) or in areas with high lightning density. Installation requires a licensed electrician and often coordination with utility companies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u0627\u0644\u0646\u0648\u0639 2 SPDs \u0645\u0646
