Description

Cast-Resin Distribution Transformer Introduction

The three-phase Cast-Resin Distribution Transformer is a high-performance Dry Type Distribution Transformer boasting core features including low loss, compact size, light weight, low noise, anti-clamping, anti-fouling, high mechanical strength, flame resistance, strong overload capacity, and low partial discharge. This Cast-Resin Distribution Transformer is widely applied in power transmission and distribution systems, hotels, restaurants, commercial buildings, stadiums, chemical plants, stations, airports, and offshore drilling platforms—especially suitable for heavy load centers and places with special fire protection requirements.

The SC(B) series products are epoxy-cast, no-load tap changer Dry Type Distribution Transformer equipped with vibration-damping devices to meet strict structural and low-noise requirements. As a premium Cast-Resin Distribution Transformer, it adopts F-class insulation, which is vacuum degassed before being injected into winding molds reinforced with glass fiber mesh. This process significantly improves the Dry Type Distribution Transformer’s mechanical strength, electrical strength, and heat resistance, endowing it with flame-retardant, explosion-proof, and pollution-free properties that address users’ core safety concerns.

The Cast-Resin Distribution Transformer is equipped with a monitoring system that controls the fan cooling system based on operating temperature and sends over-temperature trip signals in extreme conditions, ensuring safe operation. The Dry Type Distribution Transformer offers optional enclosures made of stainless steel, spray-coated cold-rolled steel, or aluminum alloy, with customizable inlet and outlet modes (top-in-top-out, bottom-in-top-out, bottom-in-bottom-out) to fit diverse installation needs. Compared to the SC(B)11 series, this Cast-Resin Distribution Transformer features enhanced energy efficiency, maintenance-free operation, and excellent moisture resistance, making it ideal for high-humidity and other harsh environments.

Cast-Resin Distribution Transformer Feature

Flame-Retardant, Explosion-Proof & Pollution-Free：The Cast-Resin Distribution Transformer adopts epoxy resin casting technology, eliminating oil leakage risks. As an Dry Type Distribution Transformer, it is inherently flame-retardant, explosion-proof, and pollution-free, meeting strict safety standards for fire-sensitive sites.
Strong Mechanical & Electrical Performance：This Dry Type Distribution Transformer has high short-circuit resistance and good lightning impulse resistance, thanks to its reinforced winding structure and high-quality insulation. The Cast-Resin Distribution Transformer’s robust design ensures stable operation under complex grid conditions.
Low Maintenance & Energy-Saving:The Cast-Resin Distribution Transformer requires minimal maintenance due to its dry-type structure, reducing long-term operational costs. Its low-loss design delivers excellent energy-saving effects, outperforming traditional models in efficiency.
Vibration-Damping & Low-Noise Design:Equipped with professional vibration-damping devices, the Dry Type Distribution Transformer operates with ultra-low noise, suitable for noise-sensitive environments. The Cast-Resin Distribution Transformer’s structural optimization further minimizes operational noise and vibration.
