Product Description

　　Product Definition

　　Dry-type transformers are primarily composed of a high-permeability silicon steel core and windings encapsulated in epoxy resin. Their key advantages include: safety, fire resistance, zero pollution, and the ability to operate directly at load centers; high mechanical strength, strong short-circuit withstand capability, low partial discharge levels, excellent thermal stability, high reliability, and long service life; low losses, low noise, significant energy-saving performance, and maintenance-free operation.

　　Features and Advantages

　　● More economical

　　Maintenance-free, energy-efficient and environmentally friendly, self-extinguishing and fire-resistant, with strong market competitiveness.

　　● High reliability

　　Core: Made from high-quality, high-permeability cold-rolled grain-oriented silicon steel sheets with 45-degree skewed lap joints; the surface is coated with epoxy resin paint, resulting in low no-load losses and low noise.

　　Windings: Made with oxygen-free copper wire or copper foil; the low-voltage winding is pre-impregnated with DMD insulation, while the high-voltage winding adopts a segmented structure with epoxy resin cast in a single pour, ensuring uniform ampere-turn distribution and minimal leakage flux. The windings exhibit high mechanical strength, low partial discharge, and excellent thermal stability.

　　Intelligent temperature control: real-time display of the hot-spot temperatures of the three phases, with the ability to query the historical maximum operating temperature. The fan can be started and stopped automatically or manually, and the system automatically issues a Level 1 over-temperature alarm and a Level 2 over-temperature trip contact signal. Optional configurations include a 4–20 mA current output or an RS232/RS485 communication interface for connection to a computer.

　　● High energy efficiency

　　Designed and manufactured in accordance with national energy-efficiency standards, significantly reducing no-load losses and improving operational efficiency.
