Product Overview
Our Transformer Electronic Potting Silicone Compound is a professional potting material tailored for transformer electronic protection, a key part of HONG YE SILICONE’s full silicone product matrix. Model HY-9055 is a new type of thermal conductive insulation silicone synthesized from organics, designed to solve transformer pain points—heat accumulation, high-voltage breakdown and electromagnetic interference. It is liquid before mixing (Component A: dark gray fluid; Component B: white fluid), cures into a low-shrinkage, dense protective layer, forming a reliable thermal conductive insulation system to ensure stable, safe operation of transformers, far exceeding ordinary Electronic Potting Compound in transformer application adaptability. Product Features & Advantages
1. Transformer-specific thermal conductivity: Thermal conductivity ≥0.8 W/(m·k), efficiently dissipates heat generated by transformer windings during operation, reduces insulation aging caused by heat accumulation, extends transformer service life and reduces failure rates.
2. Superior high-voltage insulation: Volume resistivity ≥1.0×10¹⁶ Ω·cm, dielectric strength ≥25 kv/mm, effectively resisting high-voltage breakdown, ensuring safe operation of transformer electronic components and avoiding short circuits.
3. Gentle curing & production-friendly: Cures at room temperature with fast speed (4-5h at 25℃, 20min at 80℃), no exotherm or corrosion to fragile transformer windings; low winter temperatures can be solved by proper heating, adapting to automated transformer production lines.
4. All-round transformer protection: Combines waterproof, moisture-proof, mold-proof and dust-proof properties, with excellent anti-electromagnetic interference, chemical medium resistance and weather aging resistance, adapting to harsh transformer working conditions.
5. Easy operation & high compatibility: 1:1 weight mixing ratio (easy to measure), good fluidity; optional deaeration at 0.08MPa for 3 minutes ensures bubble-free potting, firmly fixing transformer components without loosening due to temperature changes.
Technical Specifications (Model HY-9055)
This product is a two-component transformer protection potting silicone: Component A is dark gray fluid, Component B is white fluid, with dynamic viscosity of 3000±500 mPa·s. The mixing ratio is 1:1 by weight; operable time is 30-60 minutes at 25℃, curing time is 4-5 hours at 25℃ or 20 minutes at 80℃. After curing, it reaches Shore A hardness 55±5, linear expansion coefficient ≤2.2×10⁻⁴ m/(m·k), thermal conductivity ≥0.8 W/(m·k), dielectric strength ≥25 kv/mm, dielectric constant 3.0-3.3 (1.2MHz), volume resistivity ≥1.0×10¹⁶ Ω·cm, UL94-V1 flame retardancy. Other models and customizable parameters are available on request.
How to Use
1. Preparation: Fully stir Component A and B separately in their respective containers to ensure uniform material composition without stratification, critical for stable thermal conductivity and high-voltage insulation performance.
2. Mixing: Blend Component A and B strictly according to 1:1 weight ratio, stir thoroughly to guarantee consistent thermal conductivity, insulation and curing performance for transformer components.
3. Deaeration (Optional): After mixing evenly, place the glue into a vacuum container and deaerate for 3 minutes under 0.08MPa to remove air bubbles, avoiding heat accumulation and high-voltage breakdown caused by bubbles.
4. Potting & Curing: Pour the treated silicone onto transformer electronic components (windings, circuits); cure at room temperature or heat to accelerate (80℃ for 20 minutes). In low winter temperatures, proper heating can accelerate vulcanization to match transformer mass production rhythm.
