Product Description

333kVA Single-Phase Pad-Mounted Oil-Immersed Transformer

1. Product Overview

This 333kVA single-phase pad-mounted oil-immersed transformer is specially designed for underground, outdoor, and coastal power distribution scenarios. It features a fully sealed structure, low energy consumption, and high reliability, suitable for urban underground power supply, residential power distribution, and new energy grid connection scenarios, with strong adaptability to complex environments.

2. Core Advantages

(1) Underground & Corrosion-Resistant

Adopts 304 stainless steel cabinet, which is acid and alkali resistant, corrosion resistant, and suitable for long-term use in coastal, underground and other harsh environments. It can stably operate in high humidity, high corrosion and other complex working conditions.

(2) Energy-Saving & High Efficiency

Adopts high-quality silicon steel sheet and pure copper winding (aluminum optional), with low no-load loss and load loss. It meets DOE efficiency standards, which can effectively reduce energy consumption and operating costs.

(3) Fully Sealed & Low Maintenance

Vacuum oil injection and sealing technology are adopted to avoid oil leakage. No regular oil change is required under normal operation, which greatly reduces later maintenance costs and workload.

(4) International Standard Compliance

Complies with ANSI, IEEE, IEC and GB standards, supports custom voltage and frequency, and can be customized according to project requirements.
