SCB12 10kV Cast Resin Dry-type Transformer (30kVA-25000kVA) | Low Loss Power Transformer Manufacturer

application Details

SC(B)12 Series 10kv Dry Type Power Transformer

The low-voltage windings feature advanced foil winding technology, while the high-voltage coils are vacuum-cast in epoxy resin. This solid-state construction ensures a void-free insulation structure with high resistance to short-circuit stress, moisture, and partial discharge. Capable of handling temporary overloads via forced-air (AF) cooling, the SCB12 is the definitive solution for engineers requiring a stable, IEC-compliant medium-voltage transformer that withstands harsh load fluctuations and humid conditions.

Safe, fireproof, non-polluting, can run directly in load center.
Low loss, low noise, obvious energy saving effect, no maintenance.
Small size, light weight, less floor space and low installation cost.

SC(B)12 10kv Dry Type Transformer Product Overview and Features

Product Overview

The SCB12 Series represents the next generation of medium-voltage (10kV) power distribution. Engineered specifically for indoor applications and safety-critical environments, this three-phase dry-type transformer replaces traditional oil insulation with robust epoxy resin casting.
Designed to meet modern energy efficiency standards, the SCB12 significantly reduces no-load losses compared to older SCB10/SCB11 models. It is the preferred choice for infrastructure where stability, fire safety, and low operational costs are non-negotiable—ranging from commercial skyscrapers to heavy industrial plants.

Why the SCB12 Series Stands Out

Built for Longevity and Stability
Reliability isn't just a promise; it's engineered into every unit. Unlike oil-filled transformers that face leakage risks, the SCB12 offers a solid-state, maintenance-free solution.
Consistent Output: Handles daily load fluctuations with ease, ensuring smooth startups and stable voltage regulation.
Thermal Durability: Advanced heat dissipation design prevents abnormal temperature rises, even during continuous operation.
Zero Leakage Risk: The dry-type construction eliminates the need for oil pits or complex fire suppression systems, making it ideal for basements and populated areas.

Technical Deep Dive

1. Model Decoding: What "SCB12" Means for Engineers
We believe in transparency. Here is the technical breakdown of our model codes, ensuring you select the exact specifications for your single-line diagram (SLD):
S: Three-phase system compatibility.
C: Cast Resin insulation (Class F/H), offering superior moisture and dust resistance.
B: Low-voltage Foil Winding technology, which enhances short-circuit mechanical strength.
10/12: The performance level. "12" indicates reduced energy loss parameters, offering a better TCO (Total Cost of Ownership) than standard models.
2. Premium Materials & Structure
Quality goes beyond what you see on the exterior. The lifespan of our transformers is dictated by internal componentry:
The Core: Manufactured from high-permeability, cold-rolled grain-oriented silicon steel. Precision step-lap stacking reduces magnetic noise and hysteresis loss.
The Winding: High-voltage coils are vacuum-cast with epoxy resin to ensure void-free insulation. This prevents partial discharge and resists oxidation, vastly extending service life compared to open-ventilated designs.
Cooling System: An optimized air channel design allows for efficient natural cooling (AN).

Key Advantages for Your Project

1. Operational Silence
Noise pollution is a critical concern for indoor substations in offices or hospitals. Our vibration-dampening core structure ensures the SCB12 operates at decibel levels significantly lower than industry averages.
2. High Overload Capacity
Need to handle peak demand? When equipped with a forced-air cooling system (AF), the transformer can safely sustain temporary overloads (up to 40-50% increase), providing a safety margin for your facility.
3. Tailored Customization
Every project has unique constraints. We don't just sell standard boxes; we customize:
Enclosures: IP20, IP23, or IP33 protection ratings.
Dimensions: Adjusted to fit tight electrical rooms.
Interfaces: Top or side busbar entry to match your switchgear.

Applications: Where is it Used?

The SCB12 10kV Cast Resin Transformer is versatile enough for the most demanding environments:
Commercial Infrastructure: High-rise buildings, shopping malls, and data centers requiring strict fire codes.
Public Facilities: Airports, subway stations, hospitals, and schools.
Industrial Zones: Factories with sensitive equipment and fluctuating loads.
Harsh Environments: Mining operations and coastal areas where moisture resistance is key.

Frequently Asked Questions (FAQ)

Q1: What defines the SCB12 Cast Resin Transformer?
It is a 10kV medium-voltage transformer where the core and windings are encapsulated in solid epoxy resin. This design creates a fire-retardant, self-extinguishing unit that requires no cooling oil, making it safer and cleaner for indoor use.
Q2: SCB12 vs. SCB10/11: Is the upgrade worth it?
Absolutely. The "12" signifies a higher energy efficiency tier. While the physical appearance may look similar, the SCB12 utilizes superior core materials to lower no-load losses. Over a 10-20 year lifecycle, the savings on electricity bills far outweigh the initial price difference.
Q3: Does this transformer require a special fire-proof room?
No. Because it contains no flammable oil, the SCB12 does not require fire vaults, oil containment pits, or blast walls. This simplifies civil engineering work and reduces installation costs significantly.
Q4: How does it perform in humid climates?
Exceptionally well. The vacuum-cast resin forms an impenetrable barrier around the copper/aluminum conductors. This makes the transformer highly resistant to moisture, salt spray, and dust, preventing insulation degradation in tropical or coastal regions.
Q5: Can it handle emergency overloads?
Yes. The unit is designed with a robust thermal margin. For extended overload capabilities, we recommend adding our temperature-controlled forced fan cooling system (AF), which can boost capacity during peak hours without damaging the insulation.
Q6: What is the typical lifespan?
Designed for durability, the SCB12 series typically offers a service life exceeding 20-30 years under normal maintenance and operating conditions.
Q7: Do you offer international certification?
Yes. Our transformers are manufactured and tested in strict compliance with IEC 60076 standards. We provide complete type test reports and documentation to facilitate smooth customs clearance and site acceptance testing (SAT).
