The 333 kVA single phase pole mounted transformer is designed for decentralized power distribution systems, especially for residential overhead networks in urban and rural areas. It is widely used in electric utility distribution systems to provide stable and efficient power supply for homes, farms, and light industrial applications.
This oil immersed distribution transformer is engineered to meet typical operating conditions encountered in modern power grids. It supports flexible installation on utility poles, making it ideal for cost-effective and scalable power distribution infrastructure.
To meet different performance and energy efficiency requirements, the transformer is available in two core material options. The CRGO silicon steel core provides stable performance and cost efficiency, while the amorphous metal core significantly reduces no-load losses and improves overall energy savings.
Two structural configurations are also available, including a conventional type and a fully self-protected type, offering enhanced operational safety and reduced maintenance requirements in challenging environments.
This transformer is manufactured in compliance with JB/T 10317-2014 for single phase oil immersed distribution transformers. It also meets or exceeds international standards including IEC, ANSI, GB, and SANS, ensuring compatibility with global power system requirements.
The transformer is designed for safe operation, easy installation, and long-term reliability in outdoor environments. Its fully sealed structure prevents oil contamination and reduces maintenance needs, while improving operational lifespan.
With a robust mechanical design, the transformer offers excellent short-circuit resistance and high temperature tolerance. It supports high overload capacity, making it suitable for fluctuating load conditions commonly found in residential and rural distribution networks.
The optimized internal structure enhances system efficiency and reduces energy losses, contributing to improved grid reliability and lower operating costs. Its modern and compact appearance also allows seamless integration into various installation environments.
The 333 kVA pole mounted transformer is ideal for residential communities, rural electrification projects, and light commercial applications. It is commonly used in overhead distribution systems where flexible installation and reliable performance are essential.
It is also suitable for decentralized energy systems and diversified power applications requiring stable voltage supply and efficient distribution.
