Detailed Description
The 1000kVA cast-resin dry-type transformer (mainstream SCB13 series) is a three-phase, Tier 2 efficiency unit recognized as a premier choice for medium-large capacity distribution. Its defining advantage is absolute environmental safety combined with a strong load-bearing structure. Utilizing a solid epoxy resin cast, it blocks out moisture and dust while delivering unmatched flame-retardant properties—eliminating the severe fire and leakage risks associated with oil-immersed alternatives.
Engineered with large-section copper windings and an advanced dual-mode air convection cooling system, this dry type transformer achieves highly stable, low-loss operation. Operating smoothly across -25℃ to 40℃, it exhibits exceptional overload capabilities, supported by optional forced-air cooling that surges capacity by 30%. Because of its modular design and ultra-quiet performance, the dry type transformer is widely deployed in highly sensitive zones such as commercial complexes, data centers, and precision industrial main stations.

FAQ
Installing a 1000kVA dry-type transformer requires focusing on structural handling, expanded layout adaptation, and adequate ventilation. Core precautions include:
1) Installation Layout Adaptation: Maintain a safe distance of ≥1.5m from surrounding electrical equipment and cables. Reserve a broader maintenance channel of ≥1.0m to ensure safe operational space for this larger footprint.
2) Cooling Space Reservation: Ensure a clearance of ≥1.2m above the unit and ≥0.8m around the sides. Do not install in completely sealed spaces. Natural airflow must be unobstructed. If using the AF (forced air) cooling mode, the room must be equipped with adequate ventilation ducts.
3) Power Match & Grounding: Ensure the input/output voltages strictly match the 10kV grid. The enclosure and core must be reliably grounded with a resistance of ≤4Ω to provide uncompromised leakage protection.
4) Handling & Flexible Mounting: This unit is heavy (approx. 2700kg). It must be handled using dedicated lifting gear or heavy-duty forklifts, ensuring no bumps occur to the resin windings. For floor installation, the ground must be flat and solid, utilizing robust standard brackets. Tilting can impair both insulation and cooling performance.
