JIAOTAOTAO Highland Barley Paper — Professional High-Voltage Insulation Paper

▸ Product Overview

Highland barley paper is a premium electrical-grade insulation material engineered for motors, transformers, coils, and precision electronic components. As a High-voltage insulation paper, it delivers exceptional dielectric strength, stable thickness uniformity, and long-term heat resistance.
Thanks to its unique barley paper dielectric structure, the material maintains excellent mechanical strength even under continuous thermal or electrical stress, making it ideal for Class A/E electrical insulation systems.

▸ Key Features & Advantages

1. High-Voltage Dielectric Strength

The optimized barley paper dielectric layer ensures reliable breakdown resistance, making this High-voltage insulation paper suitable for transformer layer insulation and slot liners.

2. Excellent Heat & Aging Resistance

Highland barley paper maintains structural stability under long-term 105°C–120°C conditions, preventing deformation, carbonization, or adhesive absorption.

3. Smooth Surface & Stable Thickness

Uniform thickness and smooth surface allow perfect lamination with varnish, PET film, PI film, and epoxy systems.

4. Tear-Resistant Mechanical Properties

The reinforced barley paper dielectric structure ensures strong tensile strength and outstanding flexibility during motor winding or slot insertion.

5. Compatible With Multiple Electrical Systems

Works seamlessly in:

• motors

• power transformers

• inductors

• welding machines

• compressors

• household appliances
