Product Overview

SC(B) series products are resin cast dry type transformers that are installed indoor with fire prevention functions. They are the first choice for places with limited spaces, close to the load center, or special places which have higher requirements of fire-proof.

These transformers are widely used in various industries such as power stations, hospitals, factories, buildings, commercial centers, airports, transportation tunnels, chemical plants, and ships. They can operate in harsh conditions such as high humidity, fire risk, and seismic events without compromising performance.
Dry Type Power Transformer

Technical Advantages

  • Low Noise & Low Loss: Advanced design using high-quality grain-oriented cold-rolled silicon steel.
  • Low Partial Discharge: Ensures safe, long-term transformer operation.
  • Short-Circuit Resistance: Epoxy glass fiber mesh structure insulation & vacuum resin casting.
  • Fire Prevention: High-level insulation with excellent impact resistance.

Why Choose Resin-Cast Dry Type?

  • Safety: Eliminates flammable liquids, reducing leak or fire risks.
  • Maintenance-Free: No oil changes, tests, or spill cleanups required.
  • Easy Installation: No special vaults or foundations needed; place close to load.
  • Eco-Friendly: No harmful gas emissions or greenhouse contributions.
  • Seismic Resistance: Rigid structure withstands vibrations and shocks.
  • Durable: High-quality insulation materials for damp or contaminated areas.

Frequently Asked Questions

What are the main benefits of an SC(B) series dry-type transformer?
The main benefits include fire safety, moisture resistance, maintenance-free operation, and a compact design that allows it to be installed close to the load center.
Is it suitable for high-humidity environments?
Yes, the epoxy resin casting provides excellent protection against moisture ingress, making it ideal for high humidity and damp areas.
What cooling methods are used?
The transformers use Air Nature (AN) cooling for normal operation and can be equipped with Fans (AF) to increase capacity and handle overloads.
Does this transformer require an oil containment pit?
No, because it is a dry-type transformer without flammable liquids, it does not require oil containment pits, fire walls, or complex fire suppression systems.
What is the standard capacity range?
The capacity range typically spans from 30kVA up to 10,000kVA (10mva), catering to a wide variety of industrial and commercial needs.
Which standards do these transformers comply with?
They are designed and manufactured in compliance with international standards such as IEC 60726 and various national electrical safety codes.
