Repairable Silicone Gel for Cable Junction Box Potting: In-depth Analysis of SIGEL 1805 & SIGEL 3078
In power transmission, communication infrastructure and industrial automation industries, cable junction boxes are core components for connecting and protecting cable joints. Their waterproof, moisture-proof and weather resistance directly determine the operational reliability of the entire system. Traditional potting materials have obvious application drawbacks: non-repairable after curing, failure prone to moisture, narrow temperature resistance range, etc. These issues raise maintenance costs and bring potential safety risks. ELAPLUS launches two repairable silicone gels, SIGEL 1805 and SIGEL 3078. Featuring premium performance and easy repairability, they deliver an innovative technical solution for cable junction box potting. Ⅰ. Industry Pain Points of Traditional Potting Materials 1. Core Requirements for Cable Junction Box Potting Core Demand Specific Requirement Performance Index Waterproof & Moisture-proof Block moisture intrusion and protect electrical connections Low oil bleeding, high dielectric strength Electrical Insulation Stable operation under high voltage Dielectric strength ≥25kV/mm Weather Resistance Long-term outdoor anti-aging Operating temperature: -60~200℃ Stress Buffering Relieve thermal stress and mechanical vibration High elasticity, low hardness Repairability Convenient later maintenance & cost saving Easy-to-remove gel state 2. Drawbacks of Traditional Materials Drawbacks Specific Performance Resulting Problems Non-repairable curing Rigid materials like epoxy resin cannot be removed without damaging components leading to high maintenance costs. Oil bleeding & contamination Severe oil bleeding pollutes terminal blocks increases contact resistance and impairs electrical performance. Narrow temperature resistance Softens at high temperature and cracks at low temperature failing in extreme outdoor conditions Overly strong adhesion Firm bonding with substrates causes component damage during repair 3. Advantages of Silicone Gel ※Soft gel state after curing to eliminate mechanical stress ※Repairable design for easy removal without component damage ※Ultra-low oil bleeding to avoid metal contact contamination ※Wide temperature tolerance: -60℃ ~ 200℃ for harsh environments ※Superior dielectric strength for reliable high-voltage protection Ⅱ.
