50 kVA Pole-Mounted Distribution Transformer

50 kVA Pole-Mounted Distribution Transformer is prepared for overhead distribution service. It covers 11kV / 12.47kV / 13.2kV / 13.8kV input networks and 120/240V or 277V (Lighting) output distribution. It uses ONAN (Thermosiphon Optimized) cooling or thermal design data where specified. This series description presents the application, construction, protection, and specification details in finished product copy.

Product Overview

For overhead distribution service, product Overview is treated as a practical design and selection point rather than generic catalog wording.

• The 50 KVA Pole-Mounted Transformer is a compact and efficient pole transformer designed for reliable outdoor power distribution in residential, commercial, and light industrial networks. It is widely used as a standard 50 kVA transformer for medium-capacity load requirements where stable voltage conversion and low maintenance are required.
• This pole mounted transformer supports both single-phase operation and flexible banked configurations for pole mounted transformer 3 phase systems. By combining three units, utilities can easily build a 150 kVA three-phase distribution solution without the need for a large integrated three-phase transformer, improving flexibility and reducing maintenance cost.
• Designed for outdoor pole installation, it ensures long service life, stable thermal performance, and high operational efficiency in various environmental conditions.

1. Flexible Three-Phase Solution

For overhead distribution service, 1. Flexible Three-Phase Solution is treated as a practical design and selection point rather than generic catalog wording.

• The 50 kVA transformer can be used individually or combined in a bank of three units to form a pole mounted transformer 3 phase system. This modular design reduces installation complexity and allows easy phase replacement.

2. High Thermal Stability

For overhead distribution service, 2. High Thermal Stability is treated as a practical design and selection point rather than generic catalog wording.

• Advanced ONAN cooling ensures natural oil circulation inside the tank, maintaining stable temperature performance even under peak residential load conditions. This improves insulation life and reduces long-term maintenance costs.

3. Reliable Outdoor Durability

For overhead distribution service, 3. Reliable Outdoor Durability is treated as a practical design and selection point rather than generic catalog wording.

• The tank body is treated with multi-stage phosphate cleaning and powder coating, providing strong resistance against corrosion, UV exposure, and harsh outdoor environments.

4. Easy Installation and Maintenance

4. Easy Installation and Maintenance connects the product rating with the field conditions, enclosure layout, and distribution role it is normally selected for.

• Heavy-duty lifting lugs and optimized structural design ensure safe lifting and fast installation on utility poles. Individual units can be replaced without affecting the entire system.

5. Cost-Effective Distribution Solution

For overhead distribution service, 5. Cost-Effective Distribution Solution is treated as a practical design and selection point rather than generic catalog wording.

• Compared with large integrated transformers, the pole transformer banked solution significantly reduces transportation cost, spare part cost, and maintenance downtime.
