Innovativuri Solucia Arquitectura
I. Tripli Zemokmvnis Proteqtia Sistemi
• Dinamikuri Decoupling Base: Patentirdebuli hidravlikuli damperis qvekani + p'iris energet'ia saqmelebis mecnieri (IEC 61166:2025 certifikatebuli zemokmvnis intensiteti 9).
• Lagviuri K'uris C'onectebuli Q'vene: Bellows-type k'onduktivuri k'uris dizaini (±15mm aksiuli/±8mm radialuri displacmentis tolerancia).
• Kompoziti Insulacia Support: Stikl-fibris gadakveulebuli epoksiduri rezinis stulp'i (380MPa flexural strength, 3.2× daxarebda porcelanze).
II. Aktivi Gvardebi Eksplodirebis Proteqtia Strukturis
Davrebulis Monitorinq → Sakitxis Davrebulis Gamotana → Directed Emission → Mexanuri Isolation
• Nano-Ceramic Matrix Composite Enklozuri: ≥120MPa flexural strength, 400% daxarebda tradiculi stali.
• Dual-Channel Davrebulis Gamotanas Sistemi: Rupture disc (0.15MPa aktivireba) + labyrinthine gas flow channel (≥800mm arc flame decay length).
• Arc Energy Graded Dissipation: Copper-tungsten alloy arc chute plates + ZnO non-linear resistors for suppression.
III. Full-Range Environmental Adaptability Design
• Dry-Type Solid Insulation System:
o Vacuum-cast epoxy/silicone rubber composite dielectric (CTI ≥600V).
o Complete replacement of SF₆ gas (GWP=0, compliant with IEC 62271-1:2024 environmental requirements).
• IP6X Protection Level: Fully sealed structure resistant to mine dust/humidity.
• Wide-Range Temperature Compensation: Maintains 0.2 accuracy class from -40℃ to +85℃.

Typical Application Scenarios
- High-Seismic Zones: Coastal nuclear facilities (≥ Seismic Intensity 8 requirements).
- Explosion-Hazardous Locations:
o Underground coal mine distribution systems (GB 3836 explosion-proof compliant).
o Chemical plant explosion-proof areas (ATEX Zone 1 certified). - Harsh Environment Applications:
o High-altitude substations (4,500m normal operation).
o Offshore wind platforms (C5-M salt spray corrosion resistance).
Value Proposition Framework
Equipment Explosion-Proofing → System Continuity → Personnel Safety → Zero Environmental Pollution
• 40% Lower Lifecycle Cost: Maintenance-free design (30-year oil-free/gas-sealed operation).
• 92% Reduced Failure Rate: Operational data analysis (vs. traditional oil-immersed VTs).
• Carbon Reduction Benefit: ≥12.6 tons CO₂ equivalent reduction per unit annually.
