Zisheng ELECTRIC has been specialized in manufacturing 75kVA Conventional Type Single Phase pole Mounted transformer for more than 20 years, which complies with international standards such as ANSI/IEEE C57, IEC60076 and other standards. Its main function is to convert high voltage electricity (such as 11kV, 13.8kV, etc.) into low voltage electricity (such as 120V/240V), providing stable and reliable power supply to end users. It is suitable for residential, commercial, agricultural and small industrial loads. Typical specifications include mineral oil insulation (ONAN cooling), aluminum or copper windings, primary voltages 2.4kV–34.5kV grounded wye or delta (common: 7200/12470GrdY, 7620/13200GrdY, 12470GrdY/7200, 24940GrdY/14400, 34500GrdY/19920), secondary 120/240V or 240/120V split-phase, BIL ratings 95–150kV HV / 30kV LV, impedance typically 2.0–4.0%, ±2×2.5% or 5-position tap changer, conventional or CSP (completely self-protected) configurations with internal fuses, lightning arresters, weak-link protection, pressure relief valve, oil sight gauge, and ANSI 70 gray tank finish. Efficiency typically reaches 99.17–99.19% at 50% load per DOE levels, with low sound levels and corrosion-resistant hardware for extended outdoor service.
The 75kVA Conventional Type Single Phase Pole Mounted Transformer is a high-reliability overhead distribution transformer designed for residential power supply, rural electrification, agricultural applications, and small commercial distribution networks. It is widely used by utilities and EPC contractors to convert medium-voltage electricity from overhead distribution lines into safe and stable low-voltage power for end users.
Featuring a proven conventional design, this transformer provides an economical and efficient solution for areas requiring reliable electricity distribution with limited installation space. The pole-mounted structure allows direct installation on utility poles, reducing land requirements, construction costs, and infrastructure investment, making it particularly suitable for rural and remote power projects.
The transformer adopts a high-quality grain-oriented silicon steel core combined with optimized winding technology to achieve low no-load losses, reduced energy consumption, and stable voltage regulation. The oil-immersed ONAN cooling system ensures effective heat dissipation and excellent insulation performance, allowing the transformer to maintain reliable operation under continuous load conditions.
Designed for long-term outdoor service, the transformer features a durable sealed tank structure with strong resistance to moisture, dust, temperature variations, and harsh environmental conditions. The robust construction minimizes maintenance requirements while improving operational safety and extending service life.
Manufactured according to international standards such as IEC 60076 and ANSI C57.12, the 75kVA Single Phase Pole Mounted Transformer can be customized with different voltage ratings, frequency requirements, winding materials, and accessory configurations to meet specific project needs. Each unit undergoes strict factory testing, including insulation tests, winding resistance tests, voltage ratio tests, and performance inspections before shipment.
With its reliable performance, high efficiency, simple installation, and long-term durability, the 75kVA Conventional Type Single Phase Pole Mounted Transformer is an ideal solution for utility distribution networks, rural electrification programs, residential communities, agricultural projects, and infrastructure developments worldwide.
