Product description

Product Overview
The 126kV/145kV Gas-Insulated Switchgear (GIS) is the premier solution for modern urban substations and large-scale industrial parks. Designed with a Three-phase Enclosure (three phases in one tank) architecture, this system integrates circuit breakers, disconnectors, earthing switches, and current transformers into a single, hermetically sealed unit to provide maximum reliability in a minimum footprint.
Key Features
Compact Footprint: The Three-phase Enclosure design drastically reduces the equipment volume, saving more than 70% of floor space compared to traditional air-insulated switchgear (AIS).
Rapid On-site Assembly: Featuring a highly Modular Design, major components are pre-assembled and tested in the factory, allowing units to be connected like building blocks to significantly shorten the construction cycle.
Superior Sealing Integrity: Our GIS maintains an industry-leading Gas Leakage Rate of $\le$ 0.1% per year, ensuring long-term insulation stability and environmental safety.
Aluminum Alloy Enclosure: The use of high-grade Aluminum Alloy for the shell provides excellent anti-corrosion properties and eliminates eddy current losses, improving overall energy efficiency.
Low Noise Operation: Equipped with advanced spring operating mechanisms, the unit generates minimal noise and vibration, making it ideal for substations located near residential areas.

FAQ
1. How does the Three-phase Enclosure design benefit my project?
By housing all three phases in one enclosure, the total weight and size are significantly reduced. This leads to massive savings in land acquisition costs and civil engineering foundations.
2. Is SF6 gas management difficult for this unit?
Not at all. With a leakage rate of $\le$ 0.1% per year, the system is virtually "sealed for life." We also provide integrated gas density monitors with remote alarm capabilities for total peace of mind.
3. Why use Aluminum Alloy instead of Steel for the tanks?
Aluminum alloy is naturally resistant to rust, which is vital for long-term outdoor or basement installations. Crucially, it is non-magnetic, which prevents energy loss from eddy currents that occur in steel tanks.
4. How long does the on-site installation typically take?
Due to our modular design and factory pre-commissioning, the on-site mechanical assembly time is usually 50% faster than conventional GIS models.
