R-core transformer is mainly used in fields such as NC machine tools, office automation equipment, computers, television cameras, and audio equipment.

◉ Energy-efficient and stable operation:R-core transformers have low losses and temperature rise. Their simple structure, commonly in a horizontal design, allows for a compact form, making them suitable for high-density installations. The windings are circular, reducing the average turn length by 6%-10%, resulting in low copper losses.

◉ Superior materials:The core of the R series transformers uses high-permeability cold-rolled silicon steel strips, offering small hysteresisexpansion, noise reduction, reduced weight, and excellent magnetic conductivity.

◉ Compact size and low noise:At the same power rating, R-type transformers are more compact than traditional TD series transformers, making them suitable for industrial portable equipment, intelligent control cabinets, and other applications. Additionally, they produce low operating noise, meeting the needs of various industrial applications.

Q1: Are you a manufacturer or a trading company?
A: We are a direct manufacturer with over 50 years of expertise in power transformers, inductors, and reactors. Being a factory-direct supplier means you get competitive pricing, full technical support, and complete control over production quality.

Q2: What is your warranty policy?
A: We stand behind the reliability of our products with a minimum 12-month warranty. Extended warranty options are also available depending on your project requirements.

Q3: What is the lead time for mass production?
A: Our standard lead time is 7 to 25 working days, which varies based on the order quantity and customization complexity. We always strive to balance fast delivery with meticulous workmanship.

Q4: How do you ensure quality control in your factory?
A: We implement a rigorous 100% inspection system. Throughout the entire manufacturing process—from incoming raw materials to finished products—our products go through 8 dedicated QC checkpoints to guarantee zero defects and long-term operational stability.

Q5: Can you offer customized products? How do I get a tailored solution?
A: Absolutely. We specialize in fully customized designs based on your specific application and electrical parameters. Simply share your requirements, and our engineering team will provide you with the optimal solution within 48 hours.

Q6: What information do you need for a custom transformer or reactor?
A: A technical drawing is the most efficient starting point. If that’s not available, please provide your required power (capacity) rating, voltage levels, installation size limitations, insulation class, and any special environmental conditions.

Q7: How quickly can I get a price, and how do I contact you?
A: We typically issue a detailed quotation within 24 hours after receiving your inquiry. You can reach us via Email at sales@hnlsdz.com or connect with us on WhatsApp at +86 17267488565 for immediate assistance.
