When investing in critical electrical infrastructure, one of the most pressing questions is: how long will it last? For engineers and facility managers seeking a reliable, low-maintenance solution, Solid Insulated Switchgear (SIS) presents a superior alternative. Unlike traditional air-insulated systems, SIS utilizes solid insulation, a technology that inherently resists environmental degradation. At LUGAO, we engineer our Solid Insulated Switchgear for exceptional longevity, often exceeding a 30-year service life with proper maintenance, providing unparalleled lifetime value and operational stability.
The extended lifespan of LUGAO's Solid Insulated Switchgear is a direct result of its advanced design and robust construction. Key features that contribute to its durability include:
Solid Epoxy Insulation: This core component is highly resistant to moisture, dust, salt, and chemical corrosion, which are primary causes of failure in other switchgear types.
Sealed Tank Design: Our systems are hermetically sealed, preventing atmospheric contaminants from affecting the internal components and ensuring consistent performance.
Vacuum Circuit Breakers: These provide a long electrical life with minimal contact wear, even under frequent switching operations.
To understand the performance metrics in detail, consider the following technical parameters for a standard LUGAO SIS unit:
| Parameter | Specification |
|---|---|
| Rated Voltage | Up to 24kV |
| Rated Current | 630A, 1250A, 2500A |
| Short-Time Withstand Current | 25 kA / 4 sec |
| Basic Insulation Level (BIL) | 125 kV |
| Expected Mechanical Life | 10,000 operations |
| Design Life Expectancy | 30+ years |
Frequently Asked Questions About Solid Insulated Switchgear
What maintenance does Solid Insulated Switchgear require?
Solid Insulated Switchgear requires significantly less maintenance than air-insulated alternatives. The primary maintenance activities for a LUGAO unit involve periodic visual inspections, checking the integrity of the gas-tight seals, and thermographic surveys to detect any abnormal heating, typically recommended at intervals of 5-10 years.
How does Solid Insulated Switchgear perform in harsh environments?
Exceptionally well. The LUGAO Solid Insulated Switchgear's sealed tank and solid epoxy insulation make it ideal for challenging conditions. It is designed to operate reliably in environments with high humidity, coastal salt fog, heavy pollution, and wide temperature fluctuations without compromising safety or performance.
Can Solid Insulated Switchgear be upgraded or expanded?
Yes, one of the key advantages of the modular LUGAO design is its scalability. Our Solid Insulated Switchgear can be configured to allow for future expansion or functional upgrades, such as adding new feeder units or integrating advanced digital monitoring and protection devices, protecting your initial investment.
Choosing a switchgear solution is a long-term decision. The proven durability and low lifetime cost of LUGAO Solid Insulated Switchgear make it the smartest investment for ensuring a resilient and safe power distribution network for decades to come.
