SC (b) 9 / 10 / 11 series resin insulated dry-type power transformer products, with performance conforming to GB1094 11-2007 and GB / t10228-2008 standards. The product has the advantages of low loss, small volume, light weight, low noise, moisture-proof, pollution resistance, crack resistance, impact resistance, flame retardant, strong overload capacity and small local discharge (local discharge less than 15pc). This product can be widely used in power transmission and transformation systems, hotels, restaurants, high-rise buildings, business centers, stadiums, petrochemical factories, subways, stations, airports, offshore drill floors and other places. It is especially suitable for load centers and occasions with special fire protection requirements.
For indoor self cooling and forced air cooling transformers with altitude ≤ 1000 m and ambient temperature: - 25 ℃ ~ 40 ℃, it is necessary to ensure that the transformer has good ventilation capacity. When the transformer is installed in the basement or other environment with poor ventilation capacity, heat dissipation and ventilation devices must be added. The protection grade includes IP00, IP20, IP23, etc.
When the altitude is > 1000m, the user shall explain the altitude, and the design will adjust the temperature rise parameters.
It is safe, flame-retardant, fireproof and pollution-free. It can be directly installed in the load center.
Maintenance free, easy installation and low comprehensive operation cost
Good moisture resistance, can operate normally under 100% humidity.
Low loss, low partial discharge, low noise and strong heat dissipation capacity. It can operate at 130% of rated load under forced air cooling.
It is equipped with a perfect temperature protection and control system to provide reliable guarantee for the safe operation of the transformer.
High reliability. The reliability index of the product has reached the international advanced level.
