Product Overview

The SGFCO-10/300 is a high-voltage porcelain dropout fuse cutout, rated for 10kV operation with 300A/400A current options. It serves as a critical protection device in distribution networks, isolating faults and interrupting overload or short-circuit currents to maintain grid stability and safeguard equipment. Engineered to meet ANSI C37.42 and IEC 60273 standards, it combines robust insulation, precise arc suppression, and long-term reliability for demanding applications.

Product Features

◆High-Performance Insulation: Alumina-rich porcelain insulators provide 50kV/mm dielectric strength and 220mm creepage distance for Pollution Degree III environments.

◆Rapid Fault Interruption: Silver-plated fuse elements enable fault clearance within 20–30ms, adhering to IEEE C37.41 and IEC 60282-1 standards.

◆Durable Construction: Hot-dip galvanized steel brackets, stainless steel hardware, and UV-stabilized seals ensure corrosion resistance and a 25-year service life.

◆Compact & Modular Design: Dimensions of 450mm x 180mm and lightweight build simplify installation in space-limited settings.

Product Advantages

◆Enhanced Safety: Withstands 75kV lightning impulses and 35kV power frequency tests, minimizing outage risks.

◆Low Maintenance: Self-cleaning tungsten-carbide contacts and sealed enclosures eliminate routine servicing needs.

◆Operational Efficiency: Modular components reduce assembly time by 40%, while calibrated time-current curves prevent unnecessary tripping.

◆Environmental Resilience: Operates reliably from -40°C to +75°C, suited for coastal, industrial, or high-pollution areas.

Usage Scenarios

◇Utility Networks: Protects 10kV transformers, capacitor banks, and overhead distribution lines in substations and radial grids.

◇Industrial Facilities: Safeguards heavy machinery (crushers, conveyors) and HVAC systems in plants prone to electrical faults.

◇Critical Infrastructure: Ensures uninterrupted power for data centers, hospitals, and commercial complexes where reliability is paramount.

By integrating advanced insulation, fast fault response, and rugged durability, the SGFCO-10/300 provides a dependable, long-term solution for modern high-voltage protection needs.
