Product Detail

Product overview

SCB series epoxy resin cast dry-type transformer is suitable for three-phase, 50Hz, power distribution grid systems. It is used for voltage’s input from primary side and output from secondary side to the conversion of voltage. This series of transformers comply with domestic and foreign standards such as IEC 60076, GB/T 10228, GB1094, etc.

TSTY’s dry-type transformer can be divided into SCB9, SCB10, SCB11, SCB13 series according to their performance. The voltage includes 6.6kv, 10kv, 11kv, 13.8kv, 15kv, 22kv, 33kv, 35kv, etc., and capacity from 30kva to 5000kva.

SCB series products have the characteristics of maintenance-free, low loss, low noise, low temperature rise, high short-circuit resistance, strong flame retardancy, fire prevention, explosion-proof, no pollution, high temperature resistance, good moisture resistance, safe and reliable operation.


Product Advantage

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.
