The 50kVA Conventional Type Single Phase pole Mounted transformer produced by NPC ELECTRIC has a rated capacity ranging from 10kVA to 333kVA, meeting the standards of ANSI/IEEE C57, IEC60076, etc. Its main function is to convert high-voltage power (such as 10kV, 11kV, etc.) into low-voltage power (such as 220V, 240V) through the transformer for use in homes, shops, industrial equipment, etc. It is suitable for residential areas, commercial areas, rural power grids, agricultural facilities and small industrial power supply. Standard features encompass 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 99.11%+, with low sound levels and corrosion-resistant hardware for extended outdoor service.
The 50kVA Conventional Type Single Phase Pole Mounted Transformer is a reliable and efficient overhead distribution transformer designed for residential power supply, rural electrification, agricultural applications, and small commercial distribution systems. It is widely used in utility networks to convert medium-voltage electricity from overhead distribution lines into safe and stable low-voltage power for end users.
Featuring a conventional pole-mounted structure, this transformer provides an economical and practical solution for areas requiring reliable electricity distribution with limited installation space. The compact design allows direct mounting on utility poles, reducing land requirements, infrastructure costs, and installation complexity, making it especially suitable for rural and remote power distribution projects.
The transformer adopts a high-quality grain-oriented silicon steel core and optimized winding technology to achieve low energy losses, excellent voltage regulation, and stable electrical performance. The oil-immersed ONAN cooling system ensures effective heat dissipation and reliable insulation, allowing continuous operation under different load conditions and outdoor environments.
Designed for long-term outdoor service, the transformer features a robust sealed tank structure with strong resistance to moisture, dust, temperature variations, and harsh weather conditions. The durable construction reduces maintenance requirements while improving operational reliability and service life.
Manufactured according to international standards such as IEC 60076 and ANSI C57.12, the 50kVA Single Phase Pole Mounted Transformer supports customized voltage ratings, frequency requirements, winding materials, and accessory configurations to meet different project specifications. Each unit undergoes strict factory testing, including insulation tests, winding resistance tests, voltage ratio tests, and performance inspections before delivery.
With its combination of reliable performance, efficient operation, simple installation, and low maintenance requirements, the 50kVA Conventional Type Single Phase Pole Mounted Transformer is an ideal solution for utility companies, EPC contractors, rural electrification programs, residential distribution networks, and infrastructure projects worldwide.

A 50kVA Conventional Type Single Phase Pole Mounted Transformer was supplied for a rural electrification project in West Africa to improve electricity access and provide a stable power supply for local communities.
The project required a reliable and economical distribution solution for remote areas with limited power infrastructure. The transformer was installed on existing overhead utility poles to convert 11kV medium voltage electricity into 230V low voltage power for residential users, schools, and community facilities.
With its compact pole-mounted structure, efficient oil cooling system, and durable outdoor design, the transformer provides long-term reliable operation while reducing installation and maintenance costs.
