To meet diverse mounting footprint specifications and regional installation standards, Hengfengyou Electric provides the 200 kVA capacity rating in four distinct structural configurations:
200 kVA Substation Oil-Immersed Distribution Transformer: Features a corrugated cooling tank design utilizing natural oil convection (ONAN). Best suited for outdoor pole-mounted or platform-mounted utility distribution installations in rural grid revamps.
200 kVA Epoxy Resin Cast Dry-Type Transformer: Flame-retardant, self-extinguishing, and moisture-proof. Specially designed for indoor micro-equipment rooms, control booths, and commercial spaces with strict fire safety codes.
200 kVA Pad-Mounted Transformer Substation: Enclosed in a compact, tamper-proof steel cabinet integrating high-voltage load break switches and protective fuses. Designed for urban residential parks and commercial plazas.
200 kVA Low-Voltage Isolation Transformer: Built for noise isolation, voltage stabilization, and harmonic filtration in power-sensitive automated machinery.
Low-Loss CRGO Core Technology: Crafted with high-magnetic-induction silicon steel lamination sheets using a 45-degree full-mitred process, significantly reducing no-load losses and acoustic operating sound.
High Efficiency & EU Ecodesign Compliance: Achieves operational efficiency above 98.5%, fully compliant with European Ecodesign Tier 2 regulations (2015/2014/548/EC) to lower long-term electricity overhead.
Hermetically Sealed Maintenance-Free Tank: Oil expansion and contraction caused by temperature changes are naturally absorbed by the corrugated wall elasticity. This airtight seal blocks moisture and atmospheric oxygen, slowing down insulation aging and providing a maintenance-free service life over 25 years.
Strong Thermal Management & Overload Tolerance: Built with clear internal cooling ducts and high mechanical winding support. Copper winding models can safely sustain temporary short-term load surges up to 150% for up to 2 hours under monitored oil temperature (≤ 95°C).
The direct manufacturer quote for a 200 kVA 10kV/0.4kV oil-immersed transformer depends on raw material commodity markets and customized technical configurations.
Primary Price Drivers:
Winding Material Selection: Copper windings carry a higher initial investment than aluminum options, but offer lower load losses, higher mechanical strength during short circuits, and superior long-term stability.
Loss Performance Standard: Standard energy-saving models versus ultra-low loss configurations (such as European Tier 2 standards).
Fittings & Accessories: Inclusion of Buchholz relays, multi-point dial oil thermometers, pressure relief valves, or off-circuit tap changers.
Global Commodity Metal Prices: Market price fluctuations in electrolytic copper cathode and CRGO silicon steel lamination sheets.

Q1: What is the typical factory lead time for a 200 kVA distribution transformer?
For standard 10kV/0.4kV 200 kVA oil-immersed transformers, our factory manufacturing lead time is typically 20 to 25 days. Since 200 kVA is a widely requested standard rating, core laminations and corrugated tanks are regularly pre-stocked to speed up production. Customized orders take approximately 30 to 40 days.
Q2: What warranty coverage and extended service plans are available for this 200 kVA transformer?
We supply a 12-month standard warranty starting from the commissioning date (or 18 months from shipment). For rural grid contracts or commercial development projects, extended warranty packages up to 5 years are available, backed by rapid technical support and spare parts availability.
Q3: How does Hengfengyou Electric offer competitive pricing for 200 kVA power transformers?
By manufacturing directly and eliminating agent commissions, we pass volume material procurement savings straight to buyers. Automated coil winding machines and robotic tank welding systems ensure precise quality control while keeping production overhead low.
Q4: How do you calculate the primary and secondary rated currents for a 200 kVA 10kV/0.4kV transformer?
For a standard 10kV to 0.4kV step-down voltage transformation:
High-Voltage Side (10 kV): Rated Current I1 = 200 kVA / (10 kV × 1.732) = 11.55 A
Low-Voltage Side (0.4 kV): Rated Current I2 = 200 kVA / (0.4 kV × 1.732) = 288.68 A
Q5: What are the primary application scenarios for a 200 kVA oil-immersed transformer?
With a low-voltage rated current around 289 Amperes, a 200 kVA transformer is ideal for small manufacturing workshops, agricultural processing hubs, rural distribution substations, commercial buildings, and localized solar power tie-ins. It is standardly equipped with a Dyn11 vector group to effectively handle unbalanced neutral load conditions up to 100%.
