Description

Description of 20kv Three Phase Distribution Transformer

The 20kV Three Phase Distribution Transformer is a core device for medium-to-low voltage power distribution, designed to meet daily electricity needs across various scenarios. It boasts a high-voltage (HV) rating of 20kV and a low-voltage (LV) output of 400V, making it ideal for stepping down medium-voltage power to a level suitable for end users.

Core Specifications & Design

Capacity Range: Focused on practicality, it typically covers capacities up to 2500kVA—enough to support lighting systems, small-to-medium industrial equipment, and commercial power demands.
Sealed Tank Structure: Adopts a fully sealed tank design. This prevents oil leakage, dust intrusion, and moisture damage, ensuring the transformer operates safely and reliably even in harsh outdoor or indoor environments.

Flexible Installation & Usage

It offers versatile installation options to fit different site conditions:

Can be mounted on utility poles for outdoor areas (like residential neighborhoods or rural regions) where space is limited.
Suitable for indoor placement in distribution rooms, making it a top choice for commercial buildings, factories, or urban power stations.
