Phase: Three

Service Voltage: 6-35kV

Rated Capacity: 30-4000kVA

Product Description

Our SC(B) series epoxy resin cast dry transformer is cast under vacuum with thin insulating bands automatically. The core is made of high permeable grain orientated silicon sheet and cast with imported epoxy resin. Thanks to advanced technology, quality raw materials, scientific management , and perfect inspection means , our products have the following features.

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 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 core are subjected to corrosion resistant treatment. The insulating materials in the coil such as glass fiber are self extinguishing and they will not cause fire by the arc resulted from short circuit . The resin will not generate toxic or harmful gas under high temperature.

Product Features

1.Key component-iron core

The company has its own silicon steel sheet cutting line, and the iron core adopts laser-marked high-permeability silicon steel sheet---quality assurance and cost reduction;

The non-punched iron core design is combined with the 7 levels marching type strapping structure to make the electric field distribution in the iron core joints well-distributed---the no-load loss can be reduced by 4-6% by comparing with similar products in the market;

Self-designed iron core bending clamps --enhances products’ mechanical strength;

Top end-face adopts transparent resin to cast -- prevent moisture and reduce off-load loss.

2.Key component-coil

Self-designed positive casting mold and vacuum casting with epoxy resin ------ reach modern appearance and high mechanical strength;

High-quality epoxy resin with filler technology and C-level NO M E X paper insulation materials, low-temperature rise design --improve transformer’s reliability;

Foil winding low voltage coil—balances high and low voltage ampere-turn and increases mechanical strength, easy to realize mass production;

Based on epoxy resin’s structure and characteristics, the coil structure is reasonably selected, and the internal field strength distribution is improved—reduce partial discharge and improve transformer’s service life.
