The 63kVA cast-resin dry-type transformer is a core equipment optimized for small-capacity distribution systems. Utilizing enhanced resin-cast insulation and a highly efficient natural air cooling system, it merges the eco-friendly, zero-fire-risk advantages of dry-type equipment with an ultra-compact and highly stable physical footprint. It is incredibly suitable for demanding small-scale scenarios such as retail shops, community facilities (streetlights, EV charging stations), remote multi-household power, and small laboratories. It guarantees steady performance in standard climates (-25℃ to 40℃).
Core Parameters:
• Energy Efficiency: Tier 2 Efficiency (Complies with GB 20052-2024).
• Structure: Enhanced Resin Cast + Natural Air Cooling (Anti-condensation, ultra-lightweight).
• Warranty: 3-Year Standard Warranty.
Product Features
Fully oil-free enhanced resin insulation. Inherently flame retardant and self-extinguishing, ensuring absolute safety for densely populated community areas and small shops.
Meets Tier 2 efficiency standards. Pure copper windings minimize losses, while the anti-condensation resin offers a durable design lifespan exceeding 25 years.
Equipped with smart temp controllers and comprehensive surge/short-circuit protection, this 63 kVA dry type transformer features a thickened, anti-condensation enclosure that handles semi-outdoor setups with ease.
Occupying only 1/3~1/2 the volume of traditional units and weighing ≤180kg, this compact 63 kVA dry type transformer perfectly supports wall-mounting or pole installation, drastically saving infrastructure space.
Absolutely no oil testing needed. A simple semi-annual visual check and dust wipe are sufficient, making it the perfect fit for scattered, unattended power nodes.
Supports integration with a mini smart monitoring module to remotely track winding temperatures and load currents, greatly reducing manual patrol costs.
