Product Overview
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.

Core Advantages
1. Flexible Three-Phase Solution
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
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
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 & Maintenance
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
Compared with large integrated transformers, the pole transformer banked solution significantly reduces transportation cost, spare part cost, and maintenance downtime.

FAQ
Q1: What is a 50 KVA Pole-Mounted Transformer used for?
It is used for stepping down medium-voltage electricity to low-voltage supply for residential, commercial, and light industrial applications.
Q2: Can this pole transformer be used in a three-phase system?
Yes. Three 50 kVA transformers can be connected in a bank to form a pole mounted transformer 3 phase system with a total capacity of 150 kVA.
Q3: What is the difference between pole transformer and pad-mounted transformer?
A pole transformer is installed on utility poles for overhead distribution, while pad-mounted transformers are installed on ground-level concrete pads for underground distribution systems.
Q4: What is the service life of a 50 kVA transformer?
Under normal operating conditions and proper maintenance, the service life is typically 20–30 years.
Q5: Is customization available for different grid standards?
Yes, we support customization for different voltage levels, frequency standards (50Hz/60Hz), and regional utility requirements.
