答案： 一個 隔離變壓器 （亦稱為乾式隔離變壓器或磁隔離變壓器）是一種電氣安全裝置，用於將電力從交流（AC）電源傳輸至某些設備或裝置，同時將受電裝置與電源隔離。作為業界領先的 中國製造商, 我們的工業級變壓器（範圍從 1kVA 至 3500kVA, 支援 單相與三相 （各種配置）廣泛應用於數控機床、醫療設備、再生能源（太陽能／風力發電）系統、資料中心、船舶電源以及重型工廠配電網路中，用以消除電氣雜訊、防止接地迴路，並保護敏感的電子負載。.

答案： 作為直接 工廠供應商, 我們提供極具彈性的客製化工程解決方案，以滿足全球各地多樣化的電網需求。我們的標準工作電壓範圍從 100V 至 690V（可自訂）, 完全符合諸如以下國際工業標準： 208V、240V、380V、415V、480V 及 600V 系統. 此外，您可以指定所需的 頻率（50Hz／60Hz）, 繞線材料（純銅或純鋁繞組), 隔熱等級 (F 類或 H 類)，冷卻方法（AN/AF – 自然通風 / 強制通風)，以及外殼防護等級（IP20、IP23，最高可達 IP54 （適用於戶外或嚴苛的工業環境）。.

答案： As a professional 中國製造商, we offer both pure copper winding 以及 aluminum winding options to suit different budget and performance requirements. Copper windings provide higher electrical conductivity, lower energy losses, superior thermal efficiency, and a more compact footprint—making them the preferred choice for heavy-duty industrial environments. Aluminum windings offer a cost-effective alternative for projects with strict budget constraints while still delivering reliable performance under standard operating conditions.

答案： By employing magnetic induction with complete galvanic separation between the primary and secondary circuits, an 隔離變壓器 blocks common-mode noise, high-frequency transients, radio frequency interference (RFI), and lightning-induced voltage spikes. This pure, noise-free power delivery prevents data corruption in automation systems, extends the operational lifespan of sensitive CNC controllers, and protects medical or laboratory instrumentation from unexpected grid disturbances.

答案： Because we operate our own direct factory-supplying manufacturing facility, we maintain highly efficient production scheduling and raw material stock. Standard models or lightly customized transformers typically require a lead time of 7 to 15 business days. For large-scale bulk orders, high-capacity units (e.g., above 1000kVA), or highly complex multi-tap custom engineering projects, our team will provide a precise timeline during the initial quotation stage to ensure your project stays on schedule.

答案： Quality is our top priority. Every single dry-type power transformer undergoes strict multi-stage testing in our factory before dispatch. Our mandatory testing protocol includes 100% full-load testing, no-load loss and impedance voltage measurements, dielectric strength (hi-pot) tests, insulation resistance checks, and temperature rise verification. All units are built to withstand rigorous industrial conditions and are securely packed in heavy-duty, fumigation-free wooden export crates to guarantee zero damage during international shipping.

答案： While these terms are often discussed together, they describe different characteristics of a power transformer. A dry-type transformer refers to a cooling method where the core and coils are cooled by natural air circulation or forced air (AN/AF) rather than being immersed in liquid or oil, making it eco-friendly, fire-safe, and low-maintenance. An 隔離變壓器, on the other hand, refers to the electrical configuration featuring complete galvanic separation (no direct metallic connection) between the primary and secondary windings for enhanced safety and noise reduction. In modern industrial applications—such as those manufactured in our Chinese factory—our products combine both advantages: they are dry-type isolation transformers designed to provide both air-cooled safety and magnetic circuit isolation.

答案： Yes, absolutely. As a direct Chinese manufacturer and factory-supplier specializing in customized power solutions, we frequently build step-down 480V to 208V three-phase dry-type isolation transformers. These units are highly demanded in international industrial and commercial sectors (particularly across North American markets) to adapt standard industrial line voltages for CNC machinery, data centers, sensitive electronics, and distribution panels. You can also specify additional custom voltage ratios, such as 480V to 380V, 480V to 240V, or multi-tap configurations tailored to your exact project requirements.

答案： Yes, we specialize in high-voltage rating customizations. Our factory can design and manufacture robust 600V isolation transformers (as well as systems operating from 100V up to 690V custom ranges) to match heavy-duty industrial grids, heavy machinery, and specialized commercial power distribution systems. Built with high-grade electrical steel cores and premium insulation classes (F 類或 H 類), our 600V dry-type transformers ensure reliable operation, minimal thermal stress, and maximum resistance against voltage spikes and electrical noise.

答案： Our manufacturing capacity is highly scalable to support diverse commercial and heavy industrial projects. We produce dry-type isolation transformers with an extensive capacity range spanning from 1kVA up to 3500kVA. Whether you need a compact 10kVA or 50kVA unit for automation control panels or a massive 1000kVA, 2000kVA, or 3500kVA power transformer for a factory substation, our advanced production lines and strict quality testing protocols ensure optimal performance and safety.

答案： Yes, we offer comprehensive manufacturing capabilities for both 單相與三相 power transformers. Single-phase isolation transformers are typically utilized for smaller loads, control circuits, and residential or light commercial applications. Three-phase isolation transformers are engineered for heavy industrial environments, large motors, factory power distribution, and renewable energy setups. Both configurations benefit from our strict factory controls, custom voltage matching, and flexible winding options.

答案： Yes, flexible customization is one of our core strengths as a direct 中國製造商. Beyond electrical parameters, our engineering design team can customize physical dimensions, enclosure structures, color finishes, and mounting options to fit tight installation spaces. We offer various Ingress Protection (IP) ratings, including IP20 for indoor climate-controlled rooms, IP23 for standard factory floors, and IP54 weather-proof enclosures for outdoor or harsh, dust-and-moisture-heavy industrial environments.

答案： Yes, we provide flexible material options to match your budget and performance criteria. We manufacture transformers using 100% high-purity copper windings—which offer superior electrical conductivity, lower energy losses, higher thermal efficiency, and a more compact physical footprint—as well as cost-effective aluminum windings for projects requiring an optimized economic solution without compromising core reliability. All windings undergo rigorous tension control during our precision manufacturing process.

答案： To ensure seamless customs clearance, safe installation, and full compliance with international standards, every transformer shipped from our 中國製造廠 comes with a comprehensive documentation package. This typically includes a detailed factory test report (covering 100% full-load testing, dielectric strength, and impedance measurements), an operation and maintenance manual, wiring schematics, a certificate of conformity (CE, ISO9001 certified, and IEC 60076 compliance), and professional packing lists to support your global procurement needs.
