Product Description
Rockwill’s pad-mounted transformer is a fully enclosed, ground-level solution designed for stepping down high-voltage electricity to usable levels in residential, commercial, and industrial applications. Unlike pole-mounted units, our transformers are housed in tamper-proof, weather-resistant metal enclosures mounted on concrete pads, ensuring safety, durability, and space efficiency.

Key Features:

• Enhanced Safety – Fully insulated and sealed construction for operator and public protection.
• Space-Saving Design – Compact and aesthetically suited for urban environments.
• Flexible Installation – Adaptable to various site conditions without compromising performance.
• Quiet Operation – Advanced core technology reduces noise levels for minimal disturbance.

Main Characteristics

• Full Insulation & Sealed Structure – Ensures complete safety for personnel and equipment.
• Dual Fuse Protection – Features a plug-in Unika fuse (temperature & current-sensitive) and a backup current-limiting fuse for cost-effective operation.
• Insulated HV Cable Connectors – Safe, reliable, and easy to operate.
• Compatible with Ring Main & Terminal Systems – Enables flexible power supply configurations for improved reliability.
• Advanced Core Design – Three-phase three-limb or five-limb construction with step-lap technology for reduced noise, lower losses, and superior short-circuit resistance.
• Vacuum Drying & Oil-Filling Technology – Ensures high-quality insulation and extends transformer lifespan.
• Anti-Corrosion Enclosure – Specialized coating with anti-condensation, anti-salt fog, and anti-mildew properties, ideal for harsh environments.

Advantages

• Compact & Aesthetic – Ideal for urban and high-density areas.
• Tamper-Proof & Maintenance-Free – Secure design with long-term reliability.
• Easy Installation & Operation – Ready-to-deploy with minimal site adjustments.

Applications

• Urban Power Networks – Residential complexes, high-rise buildings.
• Industrial Zones – Factories, airports, train stations.
• Public Infrastructure – Schools, hospitals, commercial centers.
