When your facility demands safe, maintenance-free power distribution, the SCB10 10kV-35kV Energy Efficient Dry-type Transformer delivers proven performance. This advanced electrical equipment operates without oil insulation, utilizing cutting-edge epoxy resin cast technology. Our company has been making things for more than 20 years and has 15 top engineers and 18 patents to back it up. Compared to earlier versions, the SCB10 line has 10% less no-load losses and 5% less load losses. You can depend on it to work reliably from -40°C to +40°C thanks to its precision vacuum casting and insulation class F/H rating up to 180°C. Our more than 120 sets of high-tech equipment, such as CNC automatic winding machines and microcomputer-controlled gradient curing ovens, make sure that the quality is always the same. Each unit goes through strict ISO9001 quality management, which results in transformers that are very resistant to moisture, can work at 150% of their normal load while being cooled by forced air, and don't need any regular upkeep.

What Makes Our Dry-type Transformer Different?

You face real challenges with traditional oil-filled transformers: fire risks, environmental contamination, and costly maintenance schedules. Our dry-type solution eliminates these concerns completely.

The transformer features three-dimensional wound core construction using grain-oriented silicon steel. This design minimizes energy waste while maximizing performance. You benefit from partial discharge levels below 10pC and harmonic distortion under 3%.

Unlike oil-immersed alternatives, our units can be installed directly at your load center. No need for separate transformer rooms with elaborate fire suppression systems. This flexibility saves you significant installation costs and valuable floor space—up to 30% less clearance required.

The epoxy resin casting process creates a sealed insulation system. Moisture cannot penetrate. Dust stays out. Corrosive atmospheres won't damage internal components. Your transformer keeps running regardless of environmental conditions.

Technical Specifications That Matter to Your Operations

Understanding the numbers helps you make informed decisions. Here's what our product delivers:

These specifications translate to real-world benefits. You can deploy units in harsh industrial environments. They perform reliably at high altitudes. Temperature extremes don't affect operation.

Where You'll See Outstanding Performance?

Your facility type determines specific requirements. Our transformers adapt to diverse applications:

Commercial Buildings & Urban Centers

High-rise offices, shopping malls, and residential complexes demand indoor installation safety. You can place our dry-type units in basement electrical rooms with limited ventilation. No oil means no fire hazard. No special containment systems required. Noise stays below 65dB—quiet enough for occupied spaces.

We've delivered solutions to projects like the Xinhuai Central Complex and Huaihai Xintiandi development. These installations prove reliable performance in space-constrained environments.

Industrial Manufacturing

Chemical plants, pharmaceutical facilities, and food processing centers cannot risk oil contamination. Our resin-cast design eliminates this concern entirely. You get stable power distribution in corrosive atmospheres and dust-laden environments.

Our work with XCMG Group factory power supply upgrades demonstrates capability in demanding industrial settings. We completed installations ahead of schedule while maintaining strict quality standards.

Critical Infrastructure

Subway stations, airports, data centers, and hospitals require 99.9% reliability. The SCB10 10kV-35kV Energy Efficient Dry-type Transformer meets this challenge. Our reference projects include Xuzhou Rail Transit Network Control Center and Xuzhou High-speed Railway East Station—installations where failure isn't an option.

Variable frequency drives create harmonic distortion. Our transformers handle total harmonic distortion up to 15% without derating. Enhanced K-factor ratings (K-4 to K-13) ensure compatibility with modern electronic loads.

Renewable Energy Installations

Solar farms and wind power stations benefit from our flexible, customizable configurations. You can adjust capacity, protection levels, and wiring arrangements to match specific project requirements.

Maintenance-Free Operation Reduces Your Total Costs

Traditional oil-filled transformers demand regular attention. Oil testing. Leak inspections. Bushing maintenance. These tasks add up to significant expenses over decades of operation.

You won't face these costs with our dry-type solution. The sealed resin construction requires no routine maintenance. Annual visual inspections take minutes. Bi-annual electrical testing—insulation resistance and power factor measurements—verify continued performance.

Comprehensive testing every 5 years follows IEEE C57.12.91 standards. Even with professional testing services, your total ownership costs drop by 30% compared to oil-filled alternatives.

The transformer operates for 25-30 years with minimal intervention. This longevity protects your capital investment while reducing lifecycle expenses.

Compact Design Maximizes Your Usable Space

Space costs money. Every square meter dedicated to electrical equipment reduces revenue-generating area. Our design philosophy prioritizes compact footprints.

The transformer is 28% thinner than conventional oil-filled units. This makes it ideal for mezzanine installations and tight electrical rooms. You'll appreciate the space savings during retrofits where existing infrastructure limits options.

Standard clearance requirements drop from 3 meters (oil units) to 1.5 meters. You eliminate oil containment systems. Fire suppression infrastructure becomes unnecessary. These reductions multiply the effective space savings.

Dynamic Insulation Performance You Can Trust

Humidity challenges many electrical systems. Moisture ingress causes insulation breakdown and eventual failure. Our vacuum-cast resin technology solves this problem permanently.

The insulation maintains 30% higher dielectric strength after 240 hours in humid conditions. Hydrophobic surface treatments repel water. Even at 95% relative humidity, your transformer operates normally.

You can shut down for maintenance and restart immediately. No pre-drying required. No waiting periods. This operational flexibility proves valuable during emergency repairs or system reconfigurations.

IEC 60068-2-78 damp heat testing validates this moisture resistance. Our transformers exceed standard requirements.

Seamless Retrofit Compatibility

Replacing aging oil-filled transformers often creates complications. Different electrical characteristics require system modifications. Connection points don't align. You face unexpected costs and extended downtime.

We designed our product for seamless compatibility. Electrical parameters match oil-transformer specifications. You can swap units without modifying upstream or downstream equipment.

Connection points align with standard configurations. Mounting dimensions accommodate existing foundations. This compatibility makes retrofits straightforward and economical.

Our experience with hundreds of municipal, commercial, and industrial projects ensures we understand retrofit challenges. We provide tailored solutions that minimize disruption to your operations.
