S20 Oil Immersed Transformer 10kV-35kV

S20 Oil Immersed Transformer 10kV-35kV - Reliable Power Distribution Solutions

The S20 Oil Immersed Transformer 10kV-35kV from Xuzhou Tuojie International Trade combines proven oil-immersed technology with modern engineering. For voltages of 10kV, 15kV, 20kV, and 35kV, our transformers have capacities ranging from 30KVA to 31,500KVA. Expect less energy loss and lower running costs when the efficiency number is between 98.5 and 99.2%. Our team of 15 top engineers and 18 patents backs up these units, which have advanced cooling systems, extensive safety devices, and the ability to withstand short-circuits. Following ISO9001 standards for strict quality control, we make sure that every transformer meets strict performance criteria before it is delivered.

What Makes Our Oil Immersed Transformers Different?

Managing heat and being reliable in difficult circumstances are problems that many traditional transformers have. These problems are directly dealt with by our goods.

Superior Cooling Performance

The straight oil duct design makes it much easier for heat to escape. Your transformer works at lower temperatures, which makes tools last longer. Naturally, this way of cooling works, and there aren't any complicated processes to keep up.

Built for Tough Environments

Bad weather shouldn't be able to cut off your power. Our transformers work efficiently in temperatures ranging from -40°C to +40°C. The fully sealed tank design keeps water and other contaminants out.

You get security that is rated IP and is good for outdoor setups. These units keep working even when they're near the coast or in industrial areas with toxic air.

Intelligent Load Management

Changes in voltage can hurt sensitive electronics. Our transformers have smart control systems that can handle changes in load without any problems. Even when the motor starts, you'll be able to keep the voltage stable within very small ranges.

Why Choose Oil Immersed Technology?

Lower Total Cost of Ownership

The initial spending is important, but so are the ongoing costs. Most of the time, oil-immersed transformers are cheaper than dry-type options, both up front and over the life of the transformer.

Your energy bills will go down because of the gains in economy. A machine that is the right size can save you thousands of dollars a year in lost revenue.

Proven Durability

You need tools that always works and never stops for no reason. Immersion in oil is a great way to keep things warm or cool. With the right care, this makes the generator last much longer than 30 years.

Your transformer can handle short-term spikes without damage because it has a high overload capacity. This freedom comes in handy when demand is high.

Flexible Capacity Options

You can choose the right size for your needs, from 30KVA for small sites to 31,500KVA for large installations. The product can be scaled up or down to meet different power needs.

Industrial sites, utility substations, and mining activities can all use high-capacity designs. You won't lose the money you spend.

Real-World Applications

Industrial Manufacturing

Steel mills, chemical plants, and automotive facilities demand uninterrupted power. Our transformers deliver 99.9% uptime reliability. They handle complex load patterns, including motor starting currents up to 600% rated values.

Voltage stability remains within ±2% during production cycles. Your sensitive equipment stays protected.

Power Distribution Networks

Utility companies serve thousands of customers through distribution substations. The S20 Oil Immersed Transformer 10kV-35kV operates reliably in remote locations with minimal maintenance needs.

Remote monitoring capabilities let you track performance without site visits. Predictive maintenance features reduce unplanned outages by 60-80%.

Mining and Oil Extraction

Mining sites are usually very rough places to be. Extreme temperatures, high altitudes, and environments that eat away at metal make normal tools less useful. Because these are such tough jobs, our transformers have better closing and cooling systems.

With the right derating, you can work safely up to an altitude of 4,000 meters.

Commercial and Residential Distribution

Power that is quiet and stable is needed in shopping malls, hospitals, and residential places. Because they produce less than 55dB of noise at one meter, our transformers can be used in places with a lot of people.

Eco-friendly insulation oils have a small effect on the environment but still do a great job of conducting electricity.

Our Manufacturing Excellence

Advanced Production Capabilities

We operate over 120 sets of modern equipment. CNC automatic winding machines ensure precise coil construction. Static vacuum casting machines produce high-quality insulation systems.

This automation improves consistency while reducing production time. You receive transformers manufactured to exact specifications.

Comprehensive Quality Control

Quality begins with raw material inspection and continues through every production stage. Our process includes:

• Incoming material verification
• In-process monitoring at critical points
• Finished product electrical testing
• Oil analysis and insulation verification
• Final inspection before packaging

No transformer leaves our facility without passing all quality checkpoints. This "zero defects" philosophy protects your investment.

Technical Expertise

Our engineering team includes 15 senior engineers and over 30 intermediate technicians. This expertise enables custom solutions for unique requirements.

Whether you need special voltage configurations, enhanced environmental protection, or specific certification compliance, we can accommodate your needs.

Proven Project Experience

Our company has finished hundreds of important power projects in the business, industry, and municipal sectors:

For city projects, our transformers are trusted by train transit systems, high-speed rail stops, and hospitals. Dual-circuit systems make sure that the machine keeps running even when the power goes out.

Commercial Developments: Our equipment is used to make sure that power is distributed safely in shopping malls, leisure places, and mixed-use properties.

Industrial Uses: Our transformers are used in plant power supply systems by big companies like XCMG Group. Getting projects done ahead of plan shows that we can deliver on time.

FAQ

Q: How long will my transformer last, and what maintenance is required?

You can expect 30-35 years of service life with proper care. Annual inspections include oil analysis, visual checks, and protection system testing. Major internal inspections occur every 10-15 years. Oil regeneration typically happens every 15-20 years based on dissolved gas analysis results.

Q: Can these transformers handle extreme weather conditions?

Of course. The temperature range for operation is from -40°C to +55°C. For installs in the Arctic, we have special kits for cold weather. Coatings that don't rust and better seals protect against harsh conditions. It comes with standard IP54 protection, and IP65 protection is offered for marine or highly industrial areas.

Q: What efficiency levels should I expect?

Depending on their size, our product types are 98.5 to 99.2% efficient. This is 0.3% to 0.5% more efficient than a normal generator. A normal 1MVA unit saves between $8,000 and $12,000 a year on energy costs compared to other types. Your payback time is three to five years, just from lower costs.

Q: What monitoring capabilities are available?

Online dissolved gas analysis systems, moisture monitors, multi-point temperature tracking, and partial discharge detection are some of the more advanced units. Real-time data transfer is possible with remote SCADA integration. With these prediction analytics, you can plan maintenance ahead of time and avoid problems that come up out of the blue.

Q: What about transportation and installation?

Heavy-haul equipment is needed for units bigger than 2MVA. We help people plan their transportation by analyzing routes and other tasks. For installation, you need to make sure the base is ready, let the concrete cure for 28 days, make sure the crane can handle the job, and use professional oil filling methods. Our expert team can help you with the steps needed to get the site ready.

Q: How do I know I'm getting consistent quality?

Every transformer undergoes rigorous testing including turns ratio measurements, impedance verification, no-load and load loss tests, and insulation integrity assessment. We perform power frequency withstand tests and impulse voltage tests simulating lightning strikes. Third-party inspection certificates are available upon request.
