The Grade 1 energy-efficiency SC(B)18 cast-resin insulated distribution transformer offers self-extinguishing flame retardance, moisture resistance, crack resistance and maintenance-free operation.

It is widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, and power plants, and is especially suitable for installation in locations with strict fire-protection requirements such as flammable and explosive environments.

1. Long-round cross-section and two-frame three-limb construction; no-load loss is reduced by approximately 30% on average compared with SC(B)10 type, delivering significant energy savings.

2. HV windings use copper wire; LV windings use copper wire or copper foil with fiberglass mesh filling, vacuum epoxy casting and curing into a solid assembly with high mechanical strength, low partial discharge and high reliability.

3. Windings are non-hygroscopic; core clamping parts have molded anti-corrosion protection and can operate at 100% relative humidity and in harsh environments without dehumidification during intermittent operation.

4. Low losses, excellent energy savings, economical operation and maintenance-free service.

5. Compact size, light weight, small footprint and low installation cost; no oil sump, fire-fighting facilities or standby power supply required.

Standards: GB 1094.11, GB/T 10228, IEC 60076.11, GB 20052-2024; rated HV 10 (11, 10.5, 6.6, 6.3, 6) kV, tap range ±2×2.5%; rated LV 0.4 kV; connection group Dyn11; insulation level LI75kV / AC35kV.
