Product Description
Pure Copper Wire Industrial EE65 Planar Transformer for PV Solar Inverter Components
The EE65 high frequency switching power transformer is engineered for high-power energy-conversion equipment such as PV solar inverters, hybrid energy-storage systems, UPS and industrial SMPS. Built on a low-loss ferrite EE65 core and wound with 100% pure copper wire, it delivers stable power transfer, low temperature rise and reliable insulation under continuous industrial duty. Windings, turns ratio, pin-out and creepage design are fully customizable to your schematic.
Key Features
- 100% Pure Copper Winding — no copper-clad aluminium; lower DCR, lower copper loss and better efficiency at full load.
- Low-Loss Ferrite EE65 Core — optimized for 20-100 kHz switching, controlled flux density to avoid saturation.
- Reinforced Insulation System — margin tape + layer insulation, high dielectric strength between primary and secondary.
- UL Recognized Materials — built with UL-listed bobbin, tape and magnet wire (UL File No. E332338).
- Wide Temperature Operation — designed for −40 °C to +125 °C ambient in sealed inverter cabinets.
- OEM / ODM Supported — inductance, turns ratio, leakage inductance, pin configuration and terminal type made to drawing.

FAQ
Q1: Can you build the transformer to our own drawing?
Yes. Send us the schematic or specification sheet (inductance, turns ratio, power, frequency, pin-out) and we will return a design proposal and sample quotation.
Q2: Do you use pure copper wire?
Yes, 100% pure copper enameled wire as standard. Litz wire or triple-insulated wire (TIW) is available for high-frequency or reinforced-insulation designs.
Q3: Are samples available?
Samples are available for evaluation; sample charges are refundable against the first mass-production order.
Q4: What test reports can you provide?
Inductance / turns-ratio / DCR / Hi-Pot reports and temperature-rise curves can be supplied with each shipment on request.
Send us your specification today — our engineers will reply with a technical proposal and quotation for your EE65 high frequency transformer within 24 hours.
