Junengda 2500 kva Pad Mounted Transformer FAQ>>>
Q1: What are the key specifications of the Junengda 2500 kVA Pad-Mounted Transformer?
A: The Junengda 2500 kVA pad-mounted transformer features a robust design with a 2500 kVA capacity, single or three-phase configuration, and voltage customization up to 35 kV. It utilizes high-grade silicon steel for the core to minimize hysteresis and eddy current losses, ensuring ≥ 98% efficiency. Standard accessories include pressure relief devices, lightning arresters, and tamper-proof enclosures meeting IP67 protection.
Q2: Where is the Junengda pad-mounted transformer typically installed?
A: This 2500 kVA pad-mounted transformer is ideal for underground distribution networks, suburban residential complexes, industrial parks, and renewable energy grid connections. Its corrosion-resistant enclosure allows safe outdoor installation in diverse climates, including high-humidity or coastal environments.
Q3: How is the Junengda transformer installed for optimal safety?
A: Installation requires a level concrete pad with integrated grounding. The grounding system must use ≥30 mm² copper conductors buried >1 meter deep, supplemented by vertical electrodes to reduce resistance below 5 Ω. High-voltage cable terminations must pass insulation resistance and phase verification tests before energization.
Q4: What maintenance does the Junengda 2500 kVA transformer require?
A: Perform quarterly inspections: check oil levels (if oil-filled), listen for abnormal sounds, measure cable joint temperatures with infrared thermometers, and verify bushing integrity. Annual maintenance includes insulation resistance testing and tightening electrical connections to prevent hotspots.
Q5: Why does the transformer core require single-point grounding?
A: Single-point grounding prevents dangerous floating voltages that cause arcing, while avoiding multi-point ground loops that induce circulating currents and overheating. Junengda transformers include a dedicated ground terminal to eliminate this risk.
Q6: How does Junengda ensure low voltage drop in remote installations?
A: Our 2500 kVA pad-mounted transformer supports input voltage adjustment (e.g., +5% tap settings) to compensate for line losses. For long cable runs, calculate voltage drop using ΔV = 2I × ρ × L / S (where ρ = 0.0175 Ω·mm²/m for copper), and size conductors accordingly.
Q7: Can this transformer improve site power factor (PF)?
A: Yes, with an optional integrated capacitor bank, the Junengda pad-mounted transformer corrects PF to ≥0.92, reducing utility penalties (e.g., “force adjustment fees”) and increasing system capacity by up to 15%.
Q8: What is the operational lifespan and warranty?
A: The Junengda 2500 kVA pad-mounted transformer has a 30-year design life. We offer a standard 5-year warranty covering materials and workmanship, extendable to 10 years with certified installation.
