33KV (35kv) Three-phase Epoxy Resin Cast Dry-type Distribution Transformer

Advantages

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.

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.
