Zi'sheng ELECTRIC'S 167kVA Single Phase pole Mounted transformer is a high capacity single phase distribution transformer designed for medium to high load distribution systems. It is mainly used in residential, commercial, agricultural and light industrial applications to provide stable single phase power to ensure reliable operation of user-side equipment. It complies with international standards such as ANSI/IEEE C57, IEC60076 and other standards to ensure its high quality and stability. Standard features 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 (options for 277V/480V or custom), BIL ratings 95–150kV HV / 30kV LV, impedance typically 1.5–4.5%, ±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 99.33% at 50% load per DOE levels (with 2029 amendments targeting further reductions for units ≥100 kVA), with low sound levels and corrosion-resistant hardware for extended outdoor service.
The 167kVA Conventional Type Single Phase Pole Mounted Transformer is a high-capacity overhead distribution transformer designed to provide reliable and efficient power distribution for residential communities, rural electrification projects, agricultural facilities, and small commercial applications. It is mainly used to step down medium-voltage electricity from utility distribution networks into safe and stable low-voltage power for end users.
Designed with a conventional single-phase structure, this transformer combines proven technology, compact installation, and reliable performance to meet the requirements of overhead power distribution systems. The pole-mounted design allows installation directly on utility poles, reducing land usage, construction requirements, and infrastructure costs, making it an ideal solution for areas where space and installation efficiency are important.
The transformer adopts a high-quality grain-oriented silicon steel core and optimized winding design to achieve low energy losses, excellent voltage regulation, and stable electrical performance. The oil-immersed ONAN cooling system provides efficient heat dissipation and reliable insulation, allowing continuous operation under various load conditions while extending the service life of the equipment.
Built for long-term outdoor operation, the transformer features a strong sealed tank structure with excellent resistance to moisture, dust, temperature fluctuations, and harsh environmental conditions. The durable design ensures dependable performance with minimal maintenance requirements, even in remote or challenging installation environments.
Manufactured according to international standards such as IEC 60076 and ANSI C57.12, the 167kVA Single Phase Pole Mounted Transformer can be customized with different voltage ratings, frequency requirements, winding materials, and protection accessories to meet specific project requirements. Each transformer undergoes strict factory testing, including insulation tests, winding resistance tests, voltage ratio tests, no-load loss tests, load loss tests, and performance inspections before delivery.
With its combination of high power capacity, efficient operation, compact structure, and long-term reliability, the 167kVA Conventional Type Single Phase Pole Mounted Transformer is an excellent power distribution solution for utility companies, EPC contractors, rural electrification programs, residential networks, and infrastructure projects worldwide.

A 167kVA Conventional Type Single Phase Pole Mounted Transformer was supplied for a residential and rural power distribution project in Africa to improve local electricity capacity and provide a stable power supply for growing communities.
The project required a reliable overhead distribution solution with higher capacity to support increasing residential electricity demand. The transformer was installed on existing utility poles to convert 11kV medium voltage electricity into 230V low voltage power for households, schools, small businesses, and community facilities.
With its compact pole-mounted structure, efficient oil-immersed cooling system, and durable outdoor design, the transformer delivers stable performance while reducing installation costs and maintenance requirements.
