Product Description

Product Description

Oil-immersed Type Transformer

Iron core:
the iron core is made by crystal grain-oriented silicon-steel sheet; GEORG cross cut shear (made in West Germany) is adopted to cut the silicon-steel sheet with a 45°joint seam;fold the sheet into a multistage roll cross-section to reduce the noise and power consumption.
Coil:
cylinder type for high voltage; cylinder type or foil type for low voltage;this can increase the ability to resist short circuit and strike; and the distribution of magnetic path is more rational.
Oil tank:
the oil tank is made by fine cold-rolled steel sheets; GEORG corrugation oil tank production-line is adopted; to meet environmental needs, then, antiseptic coating material is applied on the surface, which can meet the requirements for petroleum and chemical industry (much oil stain and many chemical substances). In addition, the corrugations not any possess heat radiation function, but also meet the requirement for oil expansion and oil contraction trader normal performance. The iso lation from air guarantees a low aging speed of oil and a long life expectancy of transformer.
Insulation structure:
oil-immersed distribution transformer adopts A-level insulation structure; high voltage coil and low voltage coil are concentric; the space between coils is cardboard sleeve small oil clearance oil partition structure.

Product Advantage

Our products not only stand the test of details, but also have many advantages, such as the following:
1.High voltage switchgear, transformer, low voltage switchgear trinity, integrity is strong. It has the advantages of small footprint, less investment, short production cycle, convenient movement and so on.
2. High and low pressure chamber layout is reasonable and compact, easy operation and maintenance. High voltage switchgear with anti-error interlock function, safe and reliable operation, simple maintenance.
3. It has various types, such as multipurpose type, villa type, compact type, etc. It can be divided into "needle" shape layout and "wood" shape layout.
4. The transformer room is equipped with a thermostat, which can automatically control the transformer temperature to ensure that the transformer runs at full load.
5.FTU can be installed in the high voltage ring network cabinet to realize the reliable detection of short circuit and single phase ground fault. With "four far" function, easy to upgrade the distribution network automation.
6. Noise Reduction
The oil acts as a sound-dampening medium, reducing operational noise significantly (often <60dB), making them suitable for residential areas or noise-sensitive environments (e.g., hybrid microgrids with nearby communities).

Working Environment

alized oils (e.g., synthetic esters for high-temperature solar CSP plants or paraffin-based oils for cold regions).Ideal for desert solar farms (high daytime heat) and arctic wind farms (freezing temperatures), thanks to temperature-resistant insulation and cooling systems.
2. Harsh Outdoor Environments
3 Heavy-Duty Applications:
Large-scale renewable energy plants (solar/wind/hydro farms) requiring high kVA/MVA ratings (500kVA–100MVA+).
Industrial facilities (e.g., manufacturing plants, data centers) with continuous high-load operations or short-term overload demands (e.g., surge loads from renewable intermittency).
4. High-Voltage Transmission Systems
Voltage Compatibility:Designed for 10kV–220kV systems (and higher in specialized cases), making them critical for:Substations in on-grid renewable energy networks.
Long-distance power transmission from remote wind/solar farms to urban grids.
5. Moisture- & Corrosion-Prone Areas
Sealed/Hermetic Designs:Prevent moisture ingress in underground substations, flood-prone regions, or high-humidity coastal zones.
Corrosion-resistant tanks (galvanized steel or stainless steel) suit industrial environments with chemical fumes or airborne pollutants.
6. Noise-Sensitive Locations
Low-Noise Operation:Oil-dampened cores reduce noise to <60dB, making them suitable for:Hybrid microgrids in residential areas or near ecologically sensitive zones (e.g., wildlife habitats near solar farms).
Urban renewable projects (e.g., rooftop solar with grid-connected transformers).
7. High-Altitude Regions
Altitude Adaptability:Specialized designs for >1000m above sea level (e.g., mountain wind farms or highland solar plants), addressing reduced air density and increased dielectric stress.
