Transformer Details
PRODUCT OVERVIEW
SG (H) series dry-type transformer is a type of transformer whose core and winding is not immersed in insulating oil. Structurally, it can be divided into two types: (1) Solid insulation encapsulated winding. (2) No encapsulated winding. Ideal for fire-proof and explosion-proof locations such as general buildings and subways.
PERFORMANCE CHARACTERISTICS
  • No oil, no pollution, flame retardant, self-extinguishing and fire prevention.
  • Low loss, high efficiency and low noise.
  • Small local discharge (under 30 PC) and high reliability for long-term safe operation (up to 30 years).
  • Resistance to crack and temperature change, high mechanical strength, and strong sudden short-circuit resistance.
  • Good moisture-proof property; can run normally under 100% humidity without drying treatment.
  • No need for separate transformer room or oil collecting pits, reducing construction costs.
  • Easy installation, no debugging, and almost no maintenance required.
