Single-phase pole-mounted cylindrical transformer

1. Core Features (核心特点)

① Compact & Space-Saving

Integrated cylindrical design (diameter 500-800mm, height 1200-2000mm) – 30%-40% smaller than traditional box-type transformers.

Mounted directly on utility poles (150-250mm diameter) via hoops, no need for independent transformer rooms, ideal for narrow areas (residential communities, rural roads).

② Strong Outdoor Adaptability

Weather-resistant: Cold-rolled steel tank with double anti-corrosion coating (epoxy + electrostatic spraying), works stably at -30℃ to +45℃ (RH ≤95%, no condensation).

Protective design: Conical rain cover, rubber-sealed cable ports (IP54 standard, IP55 optional) – prevents dust, water, and small animals from entering.

③ High Efficiency & Low Loss

Uses high-grade cold-rolled silicon steel (30Q130+) and oxygen-free copper windings, reducing no-load loss by 15%-20% and load loss by 10%-15%.

Meets national Level 2 energy efficiency (GB 20052-2020), saving long-term electricity costs.

④ Safe & Easy to Maintain

Insulation: Imported mineral oil (or optional vegetable oil) with dielectric strength ≥35kV/2.5mm, insulation life 20-25 years.

Protection: Built-in pressure relief valve, oil level gauge, temperature alarm; external drop-out fuse + lightning arrester (anti-overcurrent, anti-lightning).

Easy maintenance: Detachable top cover for quick inspection/replacement of internal parts.

2.Key Technical Parameters (关键参数)

3. Typical Applications (典型场景)

Urban/Rural Residences: Powers 80-120 households (30kVA model) for daily appliances, no occupation of community green space.

Small Commercial/Public Facilities: Supplies convenience stores, street lamps, traffic lights (10kVA model meets a store + 20-30 lamps).

Rural Grid Upgrading: Solves low voltage/high loss in remote areas, reduces rural grid operation costs.
