35kV Epoxy Resin Contact Box for High-Voltage Insulation
As a leading manufacturer of high-voltage insulation components, our 35kV Epoxy Resin Contact Box is engineered to deliver exceptional performance and safety in demanding electrical environments.
Core Features:
High-Voltage Insulation
Withstands 35kV power frequency voltage (80kV/min) and 170kV peak lightning impulse voltage, ensuring reliable insulation between phases and phase-to-ground.
Optimized internal electric field distribution minimizes partial discharge risks, enhancing long-term operational stability.
Advanced Material Technology
Utilizes modified epoxy resin reinforced with Al₂O₃/SiO₂ fillers, offering superior mechanical strength and thermal resistance (up to 130°C).
Exceptional dielectric properties: dielectric strength ≥25kV/mm and Comparative Tracking Index (CTI) ≥600V, ensuring resistance to electrical tracking and environmental degradation.
Anti-aging and hydrophobic design for harsh conditions, including humidity, pollution, and temperature fluctuations (-40°C to +40°C).
Applications & Compliance
Ideal for 35kV switchgear (e.g., KYN, XGN series), ring main units, and substation equipment, our contact box ensures safe circuit interruption and arc protection. Compliant with IEC 62271 and GB/T 11022 standards, it guarantees reliability in power distribution, renewable energy systems (wind/solar), and industrial grids.
Combining precision engineering with cutting-edge material science, our product delivers unmatched insulation integrity and durability, tailored for modern smart grid challenges. Contact us to customize solutions for your high-voltage needs.
