What is the difference between scb dry-type transformer 10 and 11

In SCB10, S- stands for "three" phases, C- cast "forming", B- low-voltage "foil" winding, and 10 is the performance level code. In SCB11, S- stands for "three" phases, C- "dry" type (air self-cooling), B- low-voltage "foil" winding, and 11 is the performance level code.

SCB10---resin insulation wrapping type (low-voltage winding) Features: short-circuit resistance, impact resistance, never cracking, good heat dissipation, high insulation level SCB11---foil low-voltage coil Features: small size, light weight, low noise, pollution resistance, small partial discharge

What are the improvements of scb11 transformer compared with scb10 transformer:

1. Compared with type 10 products, no-load loss is reduced by 12%. The noise level is reduced, which greatly improves the economic benefits.

2. High mechanical strength, good short-circuit resistance, flame retardant, explosion-proof and pollution-free, can be directly installed on the load.

3. Maintenance-free, good moisture-proof performance, can operate at 100% humidity, no preheating treatment is required before commissioning, and no dehumidification treatment is required for intermittent operation.

4. Small size, light weight, no cracking, no moire on the surface, and low partial discharge.

5. High insulation level and good lightning impact resistance.

6. Strong heat dissipation capacity, can operate at 150% rated load under cold wind conditions.
