Three Phase Pad-Mounted Distribution Transformers
Overview
JF Industries provides a robust range of oil-filled three-phase pad-mounted distribution transformers, specifically designed for ground installations in residential, commercial, and industrial applications. Our transformers are available in ratings from 10 KVA to 10,000 KVA. Leveraging advanced technology and supported by our ISO-certified processes,
we ensure reliable and cost-effective solutions tailored to your specific requirements.
Key Features
Standards Compliance:
Designed to meet or exceed IEC, ANSI, WAPDA, K-Electric, and other customer-specified standards
Frequency:
Designed for 50 Hz or 60 Hz as per customized requirements.
Temperature Rating:
Capable of handling a 50°C average ambient temperature winding rise for efficient performance.
Insulation Levels:
Medium Voltage (11.0 KV, 33.0 KV) with BIL of 75/95 KV, 170 KV, respectively; and Low Voltage (1.0 KV) with BIL of 3.0 KV for enhanced safety.
Mobility:
MS undercarriage with roller wheels for models above 100 KVA.
Conservator Tank:
Integrated with a silica gel breather for models 400 KVA and above.
Corrosion Protection:
Powder-coated finish for superior corrosion resistance and an attractive appearance.
Connection Points:
User-friendly design with top cover mounted MV and LV porcelain bushings, equipped with tin-plated brass terminals for secure connections to copper or aluminum conductors.
Safety and Protection:
Includes a tank pressure relief device, arcing horns/surge arrestors, and tank ground provision with an earthing terminal. Insulated cover plate for bird protection on live terminals
