Product Overview

3150kVA 34.5KV Cast Resin Dry Type Power Transformer

A dry type transformer, also known as an air-cooled transformer, utilizes air or gas instead of liquid for insulation and cooling. This design does not immerse its core and windings in insulating oil, making it distinct from traditional oil-filled units. It is highly efficient for indoor applications and areas where fire safety is a priority.

3150kVA Transformer

Types of Dry Type Transformers

1. Cast Resin Dry Type Transformer (CRT):

  • Uses epoxy resin to encapsulate windings, protecting against moisture, dust, and corrosion.
  • Ideal for high humidity, indoor installations, and fire-risk zones.
  • Ratings range from 25 kVA up to 12,500 kVA.

2. Vacuum Pressure Impregnated Transformer (VPI):

  • Impregnates windings with class H polyester resin under vacuum to eliminate air gaps.
  • Enhanced mechanical and dielectric strength.
  • Robust construction suitable for seismic events and extreme temperature fluctuations.

Frequently Asked Questions

QAre you a direct manufacturer?
Yes, we are a professional manufacturer specializing in power equipment since 1958.
QWhat international certificates do your products hold?
Our transformers have been awarded CE, UL, and KEMA certificates. We can also assist in applying for other specific regional certifications if required.
QWhat is the standard production lead time?
Generally, production takes 4 to 6 weeks depending on the specific model and customization requirements.
QWhich payment methods do you accept?
We accept payments via T/T (Telegraphic Transfer) and L/C (Letter of Credit).
QCan these transformers be customized for specific voltages?
Absolutely. Capacity, HV/LV voltage, and vector groups can all be customized according to your local grid requirements.
QWhat cooling methods are available?
We provide both AN (Air Natural) and AF (Air Forced) cooling methods. AF can increase the capacity of the transformer for short-term overloads.
