Product descriptions from the supplier
Description
The 24kV Maintenance-Free Gas-Insulated Switchgear is a cutting-edge medium-voltage power distribution device engineered for efficiency, reliability, and low operational overhead. Designed to meet the demands of modern urban grids, industrial facilities, and renewable energy projects, it combines advanced gas insulation technology with a maintenance-free architecture to eliminate routine upkeep—all while ensuring stable power transmission.
Featuring hermetically sealed stainless-steel enclosures filled with low-GWP (Global Warming Potential) insulating gas, the switchgear avoids gas leakage and degradation, eliminating the need for regular refills or component inspections. As a key unit in 24kV distribution networks, it delivers consistent performance in diverse environments, from high-humidity industrial zones to compact urban substations, making it a sustainable choice for long-term grid stability.
Feature
True Maintenance-Free Operation：Hermetic gas chambers (leak rate ≤ 0.05%/year) and wear-resistant mechanical components eliminate routine tasks like gas replenishment, part replacement, or cleaning. Reduces lifecycle operational costs by up to 70% compared to traditional switchgear.
24kV-Level Reliability：Equipped with vacuum interrupters for efficient arc extinction and robust insulation, it withstands short circuits (up to 25kA/3s) and voltage fluctuations, ensuring a power supply reliability rate of ≥ 99.99%.
Eco-Friendly Gas Insulation：Uses low-GWP insulating gas (compliant with EU F-gas regulations) to minimize environmental impact. Fully sealed design prevents gas leakage, enhancing safety for personnel and surrounding ecosystems.
Compact & Flexible Installation：Modular design reduces footprint by 30% vs. air-insulated alternatives, fitting tight spaces like underground substations or industrial workshops. Supports quick on-site assembly for rapid deployment.
Smart Readiness：Compatible with intelligent monitoring systems to track real-time parameters (gas pressure, temperature, operational status) and trigger alerts for anomalies, enabling predictive grid management.
