Junengda 40 kva single phase pole mounted transformer FAQ>>>
Q1: What are the key features of Junengda’s 40 kVA single-phase pole-mounted transformer?
A: Junengda’s 40 kVA single-phase pole-mounted transformer is designed for rural electrification, residential areas, and small industrial applications. It features high efficiency, corrosion-resistant coatings, and robust insulation to withstand harsh weather. The compact pole-mounted design ensures easy installation and minimal footprint, while its low maintenance requirements enhance long-term reliability.
Q2: How to install the 40 kVA single-phase pole-mounted transformer safely?
A: Install the transformer in a well-ventilated, dry area, away from flammable materials. Ensure proper grounding and secure mounting on poles using corrosion-resistant brackets. Follow local electrical codes and maintain safe clearances from obstructions. Always de-energize the system during installation and consult the provided manual for wiring diagrams.
Q3: What maintenance is required for this transformer?
A: Regularly inspect oil levels, check for leaks, and monitor temperature (normal operating oil temperature ≤85°C). Clean bushings and insulators to prevent dust buildup, which can cause discharge. Schedule annual oil testing to ensure dielectric strength and address any abnormal noises or vibrations promptly.
Q4: How does the transformer handle overload conditions?
A: The 40 kVA transformer includes thermal protection to manage short-term overloads. However, prolonged overloading may trip protective devices like OCBs or MCCBs. Reduce loads immediately if the oil temperature exceeds 95°C or unusual noises (e.g., humming or cracking) occur to avoid insulation damage.
Q5: What causes abnormal oil discoloration, and how to resolve it?
A: Darkened oil indicates aging or contamination, while black oil with a burnt smell suggests internal faults (e.g., winding shorts). Replace degraded oil immediately and conduct insulation tests. Junengda recommends using certified mineral oil compatible with IEC 60296 standards.
Q6: Can this transformer operate in extreme temperatures?
A: Yes. It operates efficiently in ambient temperatures from -25°C to 40°C. For colder climates, ensure oil viscosity remains within limits, and in hot regions, verify cooling efficiency. Avoid direct sunlight exposure to prevent premature aging.
Q7: What warranties and certifications does Junengda provide?
A: The 40 kVA transformer comes with a 5-year warranty and complies with IEC 60076 and IEEE C57.12 standards. Certifications include ISO 9001 for quality management and routine testing reports for performance validation.
Q8: How to troubleshoot unusual noises from the transformer?
A: Buzzing may indicate loose core laminations, while crackling suggests internal arcing. For persistent noises, de-energize the transformer and inspect connections, bushings, and oil levels. Contact Junengda’s support team if unresolved.
Q9: What is the expected lifespan of this transformer?
A: With proper maintenance, the transformer lasts 25–30 years. Key factors include load management, timely oil replacement, and protection from environmental stressors like moisture or pollution.
