Key Features
Standards Compliance:
Designed to meet or exceed IEC, ANSI, WAPDA, K-Electric, and other customer-specified standards.
Temperature Rating:
Capable of handling a 50°C average ambient temperature winding rise for efficient performance.
Frequency:
Designed for 50 Hz or 60 Hz as per customized requirements.
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.
Robust Construction:
Built with a mild steel (MS) sealed or conservator-type tank (for higher ratings), featuring optional corrugated designs. Includes welded lifting lugs, support angles, and base channels for secure pole mounting.
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.
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.
Corrosion Protection:
Powder-coated finish for superior corrosion resistance and an attractive appearance.
Clear Identification:
Engraved nameplate displaying ratings and diagrams for easy reference.
Safety and Protection:
Features safety devices against internal and external faults, including 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.
High-Quality Insulation:
