SF6 Gas Insulated Pole-mounted Auto Sectionalizer 12kV 24kV 36kV

Product Overview

 Core Features

• SF6 Gas Insulation: Utilizes nontoxic, non-flammable SF6 gas with superior dielectric and arc quenching properties, ensuring reliable insulation and fault interruption for medium-voltage systems.
• 36kV High-Voltage Rating: Rated for up to 36kV, 400/630A, 50Hz, meeting the demands of high-capacity medium-voltage power distribution networks worldwide.
• Distribution Automation Compatibility: Seamlessly integrates with distribution automation systems and pairs with ACRs, enabling the control center to remotely isolate faulted distribution line sections for fast fault handling.
• Flexible Operation Modes: Supports direct manual operation and smart sectionalizer controller operation, with optional wired/wireless modems for full remote monitoring and control capabilities.
• All-Weather Controller Cabinet: The smart controller is enclosed in a rugged stainless steel cabinet, engineered to withstand all outdoor environmental conditions and ensure stable performance in harsh on-site settings.
• Simplified Pole-Mount Installation: Adopts a compact, easy-to-install pole-mount arrangement that minimizes labor input and on-site construction costs, enabling quick deployment for outdoor projects.
• Bushing Versatility: Offers standard porcelain bushings plus optional elastomeric insulators over epoxy apparatus bushings, adapting to diverse project specifications and environmental requirements.
• Visible Open/Close Indicator: Color-coded main contact position indicator (green = open, red = closed) is ground-visible and directly connected to the drive shaft, ensuring accurate, real-time contact status monitoring.
• Quick Spring Charged Operation: Equipped with a spring charged operator that uses compression springs for fast make-and-break operation, improving fault response efficiency and grid stability.
• Robust Corrosion-Resistant Build: Manufactured with proven, durable corrosion-resistant materials for an extended service life and high operational cycle capacity—ideal for outdoor pole-mounted equipment.
