Persia High Voltage Winding Varnish | Electrical Insulating Varnish for High-Stress Applications
Persia High Voltage Winding Varnish is an industrial-grade electrical insulating varnish based on saturated polyurethane resin, formulated with high-purity organic and inorganic chemical compounds. It forms a glossy, uniform coating with strong adhesion, enhancing both the mechanical stability and dielectric strength of electrical windings operating under high voltage stress.
This varnish is specifically engineered for windings exposed to continuous electrical stress, peak load conditions, and demanding industrial environments.
Key Features
Designed for high-voltage applications
Improved dielectric strength and electrical insulation
Excellent adhesion to copper and enameled wires
Effective penetration into winding layers
Glossy and uniform protective coating
Initial drying in 30 minutes
Full curing in approximately 5 hours at 25°C
Thermal resistance up to 92°C
Boiling point: 115°C
Suitable for both AC and DC systems
Applications
Persia High Voltage Winding Varnish is suitable for insulating and stabilizing:
Industrial electric motors (light and heavy duty)
Dynamos
Transformers
Armatures
Industrial coils
AC/DC wound electrical equipment
It is particularly effective in equipment operating under high electrical stress.
Preparation and Thinning
Dilute the varnish using Thinner 1124 at an appropriate ratio.
Mix thoroughly to achieve uniform viscosity.
The dilution ratio may vary depending on the application method (immersion, injection, or brush).
Application Method
Pour a sufficient amount over the winding.
Fully immerse the component in the varnish tank.
Use a brush for sensitive or hard-to-reach areas.
Allow to dry at ambient temperature (25°C).
Controlled industrial oven drying can be used to accelerate curing.
Advantages
Prevents short circuits under high voltage
Extends equipment service life
Enhances mechanical strength of windings
Reduces maintenance costs and downtime
Improves operational safety and reliability
