100kVA Conventional Type Single Phase Pole Mounted Transformer

Zisheng ELECTRIC has been specialized in manufacturing 100kVA 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. 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 or custom), BIL ratings 95–150kV HV / 30kV LV, impedance typically 2.0–4.5%, ±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 99.25–99.29% at 50% load per DOE levels (with 2029 amendments targeting further reductions in losses for units >100 kVA), with low sound levels and corrosion-resistant hardware for extended outdoor service.

Key Features:

Reliable Power Supply
Compact Pole-Mounted Design
High Efficiency & Low Losses
Durable Outdoor Performance

The 100kVA Conventional Type Single Phase Pole Mounted Transformer is a reliable and efficient overhead distribution transformer designed to provide stable power conversion for residential areas, rural electrification projects, agricultural facilities, and small commercial applications. It is widely used in utility distribution networks to reduce medium-voltage electricity from overhead lines into safe and usable low-voltage power for end users.

With a conventional pole-mounted structure, this transformer offers a practical and economical solution for areas requiring increased power capacity while maintaining simple installation and maintenance. The compact design allows the transformer to be mounted directly on utility poles, reducing land requirements, construction costs, and infrastructure investment, making it especially suitable for rural and remote power distribution systems.

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 provides efficient heat dissipation and reliable insulation, ensuring continuous operation under different load conditions and outdoor environments.

Designed for long-term outdoor service, the transformer features a durable sealed tank structure with strong resistance to moisture, dust, temperature variations, and harsh weather conditions. The robust construction helps minimize maintenance requirements while improving safety, reliability, and service life.

Manufactured according to international standards such as IEC 60076 and ANSI C57.12, the 100kVA Single Phase Pole Mounted Transformer can be customized with different voltage ratings, frequency requirements, winding materials, and accessory configurations to meet various project requirements. Each transformer undergoes strict factory testing, including insulation tests, winding resistance tests, voltage ratio tests, no-load loss tests, and performance inspections before shipment.

Combining reliable operation, high efficiency, easy installation, and long-term durability, the 100kVA Conventional Type Single Phase Pole Mounted Transformer is an ideal power distribution solution for utility companies, EPC contractors, rural electrification programs, residential networks, and infrastructure projects worldwide.

Rural Electrification Project – East Africa

A 100kVA Conventional Type Single Phase Pole Mounted Transformer was supplied for a rural electrification project in East Africa to improve local power distribution capacity and provide reliable electricity for residential communities.

The project aimed to expand the existing overhead distribution network and support increasing electricity demand in remote areas. The transformer was installed on utility poles to convert 11kV medium voltage electricity into 230V low voltage power for households, schools, small businesses, and community facilities.

Due to its compact pole-mounted structure, efficient oil-immersed cooling system, and durable outdoor design, the transformer provides stable operation with reduced maintenance requirements, making it suitable for long-term use in rural environments.
