The SC(B) series epoxy cast Dry-Type Distribution Transformer feature cores made of electrical-oriented silicon steel or amorphous alloy, with coils cast in epoxy resin. They offer excellent fire and moisture resistance, are pollution-free, and possess self-extinguishing, flame-retardant properties. 

Ideal for urban power grid upgrades, these transformers are specifically designed for critical locations requiring superior flame retardancy, explosion-proofing, and moisture protection. This includes high-rise buildings, commercial centers, theaters, hospitals, hotels, tunnels, subways, underground power stations, laboratories, transport hubs, docks, airports, and combined substations.

• 01
  CORE

  Design: Three-phase, three-limb laminated core with full winding coverage. 
  Performance: The optimized magnetic circuit—specifically the shorter path of the center limb—significantly reduces no-load current.

• 02
  WINDING

  Materials: Made of H-class film-coated flat copper wire and high-quality epoxy resin insulation.
  Durability: Moisture-proof, corrosion-resistant, and features low partial discharge.
  Stability: Offers excellent dynamic and thermal stability, ensuring the coils remain securely positioned during both transport and operation.

• 03
  CLAMP

  Structure: Robust frame design engineered to handle lifting weight, clamping pressure, and short-circuit mechanical forces.
  Protection: Effectively maintains the superior electromagnetic performance of the cold-rolled electrical steel.

Low Noise: Noise level below 55 dB. The transformer uses high-quality amorphous alloy, optimized magnetic flux density, and a suitable natural vibration frequency of the iron core. All clamping parts are cushioned with silicone rubber and elastic components to reduce vibration amplitude.

Low Loss: Complies with energy efficiency standards. The amorphous alloy material features a non-crystalline structure, low magnetizing power, high resistivity, and low eddy current loss. Advanced leakage flux calculation to reduce stray loss, prevent local overheating, lower winding hot-spot temperature rise. Optimized wire transposition to reduce circulating current loss caused by leakage flux.

High Dielectric Strength & Longevity: The solid insulation system, composed of premium resin and glass fiber, offers high electrical strength with partial discharge strictly controlled within ≤5pC. This low partial discharge ensures no cracking or degradation of insulation levels throughout the transformer's entire service life.

Enhanced Cooling & Overload Capacity: Equipped with a cooling system consisting of multiple low-noise radial fans, the unit effectively lowers operating temperatures and boosts overload capabilities. It is designed to handle long-term periodic loads as well as temporary emergency loading conditions.
