A 35kV dry-type transformer provides medium-voltage power conversion without liquid insulation. It is commonly selected for buildings and industrial sites where fire safety, indoor installation, low maintenance and environmental considerations are important.

XNET SCB13, SCB14 and SCB18 cast-resin transformers can be engineered for project-specific voltage, capacity, enclosure and accessory requirements.

Why Choose a 35kV Dry-Type Transformer?

Cast-resin windings are resistant to moisture and contaminants, while the absence of transformer oil simplifies fire-protection planning and eliminates the risk of oil leakage. These characteristics make dry-type units suitable for installation close to load centers.

SCB13, SCB14 and SCB18: What Changes?

The model generation generally reflects improvements in loss performance and efficiency. The right choice depends on the applicable efficiency standard, operating hours, load profile and total cost of ownership. Ask the manufacturer to provide guaranteed no-load loss, load loss, sound level and temperature-rise data for the proposed rating.

Important Specification Points

Rated Capacity and Load Profile

Include continuous load, peak demand, harmonic-producing equipment, motor starting and future expansion. Forced-air cooling may provide additional capacity, but it should not replace proper base-rating selection.

Insulation and Temperature Class

Confirm insulation class, permitted temperature rise, partial-discharge requirements and the site altitude. High altitude can affect dielectric strength and cooling performance.

Enclosure and Protection

An open unit may suit a controlled electrical room. Public, dusty or humid environments generally require an enclosure with an appropriate IP rating, ventilation design and cable-entry arrangement.

Monitoring Accessories

Common options include winding temperature sensors, a digital temperature controller, fan control, alarm and trip contacts, surge protection and communication interfaces.

Typical Applications

• Data centers and commercial complexes
• Hospitals, airports and rail facilities
• Industrial plants and mining projects
• Renewable-energy collection systems
• High-rise and infrastructure projects
