Power Transformers: Connect generators to transmission grids, stepping up voltage (e.g., 18kV to 400kV) for long-distance transport or stepping down to distribution levels. ZISHENG’s power transformers range from 300KVA to 4250KVA, compliant with IEC/UL/GOST standards.
Distribution Transformers: Deliver the final voltage conversion (e.g., 35kV to 440V) for commercial buildings, residential areas, and small industrial facilities. ZISHENG offers pole-mounted, pad-mounted, and substation distribution transformers with weatherproof designs.
Autotransformers: Serve as transmission inter-tie transformers, connecting AC networks of different voltages. Compact (1/3 the size of conventional transformers) and cost-effective, ZISHENG’s autotransformers feature enhanced impedance to mitigate short-circuit risks.
Generator Step-Up (GSU) Transformers: Directly linked to power generators, boosting output voltage to match transmission grid requirements. ZISHENG’s GSUs are engineered for continuous full-load operation with resistance to overheating and fault currents.
Auxiliary Transformers: Supply power to plant auxiliary loads (feed pumps, cooling systems, safety devices). ZISHENG’s UAT (Unit Auxiliary Transformers) and RAT/SAT (Reserve/Startup Auxiliary Transformers) ensure uninterrupted plant operation.
Specialized Transformers: Including rectifier transformers (for electrochemical plants), furnace transformers (for arc furnaces), and railway transformers (for locomotive power)—all available in ZISHENG’s industrial product lineup.
Core-Type Transformers: Windings encircle the core limbs, ideal for high-voltage, large-capacity applications (e.g., power transformers). ZISHENG uses laminated silicon steel cores to minimize flux leakage.
Shell-Type Transformers: The core encircles the windings, offering better mechanical strength and lower noise—suited for low-voltage, high-current scenarios like industrial machinery.
Single-Phase Transformers: Feature one pair of windings, used in residential areas and small businesses. ZISHENG’s single-phase transformers are compact and cost-effective for light loads.
Three-Phase Transformers: Equipped with three winding pairs, delivering consistent power for heavy industry, power grids, and large-scale projects. ZISHENG’s three-phase transformers support delta/star connections for flexible system integration.
Toroidal Core Transformers: Ring-shaped cores reduce magnetic interference, used in telecommunications and precision industrial control systems.
Oil-Immersed Transformers: Core and windings immersed in mineral oil or synthetic esters (FR3) for insulation and cooling. ZISHENG’s oil-immersed transformers (including Distribution Power Liquid Filled Oil Immersed Transformers) are ideal for outdoor industrial use, with cooling methods like ONAN (natural oil/air) and OFAF (forced oil/air).
Dry-Type Transformers: Air-cooled with solid insulation (epoxy resin encapsulation), suitable for indoor applications (underground tunnels, residential buildings) where fire risk must be minimized. ZISHENG’s dry-type transformers comply with IEEE C57.12.01 standards.
Gas-Filled Transformers: Insulated and cooled with SF6 gas, offering zero fire risk and compact design—used in high-security sites like oil rigs and urban substations.
Power Grids: Transmission and distribution transformers ensure stable voltage for city-wide and national grids, with ZISHENG’s compliant designs meeting grid access requirements.
Construction & Infrastructure: Pad-mounted and pole-mounted transformers provide temporary or permanent power for construction sites, highways, and municipal projects—ZISHENG’s weatherproof models withstand harsh job site conditions.
Heavy Industry: Steel mills, mines, and petrochemical plants rely on high-power, explosion-proof transformers; ZISHENG’s industrial-grade units offer high voltage tolerance and flame-retardant features.
Renewable Energy: Solar parks and wind farms use transformers to convert variable output to grid-compatible voltage—ZISHENG’s customizable solutions fit new energy system requirements.
Commercial & Residential: Distribution transformers power office buildings, apartments, and retail spaces, with ZISHENG’s low-noise, energy-efficient models enhancing user experience.
Transportation: Railway transformers (trackside and on-board) support train operations, while ZISHENG’s lightweight designs suit locomotive and transit system needs.
Core: Laminated silicon steel or amorphous metal cores minimize eddy current and hysteresis losses.
Windings: High-purity copper or aluminum windings ensure low resistive loss and thermal stability.
Insulation: Industrial-grade paper, epoxy resin, or mineral oil insulation (compliant with IEEE and IEC standards) prevents short circuits and dielectric breakdown.
Tap Changers: On-load tap changers (OLTC) enable voltage regulation without downtime, critical for grid stability.
Safety Features: Buchholz relays, explosion vents, and corrosion-resistant tanks protect against faults—ZISHENG’s units undergo routine tests (ratio, insulation, impulse) to ensure compliance.
IEC (International Electrotechnical Commission): For global market access, including IEC 60076 for power transformers.
UL (Underwriters Laboratories): For North American markets, complying with UL 1561 for distribution transformers.
