23kv/400v 3500 Kva Oil Type Power Transformer

 Where ZTelec’s 23kV Transformer Shines

Industrial Zones & Heavy Manufacturing: Powers high-demand equipment (e.g., metal processing machines, textile production lines, and chemical reactors) by stepping down 23kV grid voltage to 400V, ensuring uninterrupted operation for 24/7 production cycles.

Suburban & Rural Power Grid Upgrades: Eliminates the need for intermediate 10kV substations, directly connecting 23kV regional grids to 400V residential, commercial, and small-scale industrial areas—reducing infrastructure costs and energy loss.

Renewable Energy Integration: Seamlessly connects 23kV solar parks or wind farms to 400V local distribution networks. Its low impedance design accommodates fluctuating renewable energy outputs, maintaining grid stability.

Critical Infrastructure: Deployed in hospitals, data centers, and railway stations, where its robust build resists harsh conditions (humidity, dust, and temperature variations) and ensures zero downtime for life-saving or mission-critical systems.

Mining & Construction Sites: Withstands rugged on-site environments, providing reliable 400V power for heavy machinery (excavators, cranes) and temporary facilities—even in remote locations.

ZTelec’s Competitive Advantages for Engineers

Exceptional Energy Efficiency: Adopts S11-series core technology with high-grade grain-oriented silicon steel and precision-wound coils. This reduces no-load loss by 35% compared to traditional S9 models, cutting long-term operational costs for end-users.

Extended Service Life: Features a fully sealed corrugated oil tank (produced via GEORG’s advanced manufacturing line) that isolates transformer oil from air and moisture. This prevents insulation aging, eliminates oil replenishment needs, and ensures a design life of over 25 years.

Superior Short-Circuit Resistance: 3D-optimized winding structure and high-frequency welding enhance mechanical strength, enabling the transformer to withstand extreme short-circuit currents (up to 25kA) without core or coil damage—protecting downstream equipment.

Low Maintenance Requirements: IP54-rated enclosure and hermetic design minimize exposure to contaminants. Routine maintenance is limited to annual inspections, making it ideal for remote or hard-to-access sites.

Global Compliance & Customization: Certified to CE, ISO 14001 (environmental management), and IEEE standards. ZTelec’s engineering team also offers tailored modifications (e.g., tap range adjustments, cooling system upgrades) to meet project-specific needs.
