Description
Epoxy-Resin Dry-Type Distribution Transformer Product Details
Our SC(B) series epoxy-resin dry-type distribution transformer is cast under vacuum with thin insulating bands automatically.The core is made of a high-permeable grain-orientated silicon sheet and cast with imported epoxy resin.
The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin. It has good mechanical properties, is free of crack and inner bubble, and has a low local discharge, high reliability, and long service life.
The high and low-voltage systems are cast under vacuum, thus the coil will not absorb moisture, the clamps of the core are subjected to corrosion-resistant treatment and it may run under high temperature or other serious environments. 
Medium and High Voltage Epoxy-Resin Dry-Type Distribution Transformer
Medium and high voltage dry-type distribution transformer is essential equipment used in electrical power transmission and distribution, typically operating within the medium voltage range (1kV to 35kV) and high voltage range (above 35kV). Here are their key
Epoxy-Resin Dry-Type Distribution Transformer Features and functions:
  • Insulation Structure: They utilize high-performance insulating materials to ensure safe and reliable operation in high-voltage environments, minimizing the risk of electrical leakage.
  •  Heat Dissipation: Designed with effective heat dissipation capabilities, they can efficiently release heat generated during operation, ensuring stability and reliability.
  •  Environmentally Friendly: These transformers do not use liquid insulating mediums, which eliminates the risk of oil leaks and environmental pollution, aligning with eco-friendly standards.
  • Easy Maintenance: The dry-type design reduces the need for regular maintenance, lowering operational costs.
  • Flexible Installation: With a smaller size and lighter weight, they allow for more flexible installation options, making them suitable for various applications.
  • High Efficiency: Under normal operating conditions, they exhibit high energy conversion efficiency, contributing to reduced energy consumption.
  • Wide Applicability: They are widely used in urban distribution systems, industrial power, building facilities, and renewable energy projects such as wind and solar.
