Description
The Vziman 35kV oil-immersed power transformer is an efficient step-down unit for three-phase AC distribution networks. Upgraded materials and structure reduce no-load and load losses, while high and low voltage clamps tensioned with steel straps form a robust frame that strengthens core clamping and withstands transportation impact.
Strong short-circuit withstand, low noise and reliable long-term operation make it dependable core equipment for factories, rural grids and urban transmission network centers, with customized solutions and one-stop service from design to after-sales support.

35kV Oil-Immersed Power Transformer Feature

  • Multi-Voltage Compatibility — Customized for 35kV, 36kV and 38.5kV voltage levels, adapting to the grid standards of different countries and regions for industrial parks, rural grids and urban transmission networks.
  • Advanced Manufacturing & Reliable Quality — High and low voltage clamps tensioned with steel straps or beams form a robust frame, enhancing core clamping force and transportation impact resistance; strong short-circuit withstand with stable long-term operation.
  • High Energy Efficiency & Low Operation Cost — Optimized materials and processes reduce no-load and load losses; low operating noise cuts long-term energy and maintenance costs, in line with global low-carbon requirements.
  • Customized Solutions & One-Stop Service — Tailored by capacity, tapping range and connection group, covering design, R&D, production and after-sales installation guidance with guaranteed on-time global delivery.
  • Wide Application Scenarios — Ideal core equipment for factories, rural grids, urban transmission hubs, power stations and chemical plants, with strong environmental adaptability.

Frequently asked questions

A 35kV Oil-Immersed Power Transformer is a special device that helps change high voltage electricity into a lower voltage. It's called 'oil-immersed' because it's filled with oil that helps cool it down and makes it work better. These transformers are often used in factories and towns to provide electricity safely.

Q:How do I know if I need a 35kV Oil-Immersed Power Transformer?

A:If you are running a business, large factory, or need electricity for a town's power grid, you might need a 35kV Oil-Immersed Power Transformer. It’s best to ask an expert to help you understand your power needs and determine if this type of transformer is right for you.

Q:Who can use the 35kV Power Transformer?

A:These transformers are useful for many different places, like factories, rural areas, and urban power supply networks. They help to ensure that electricity is delivered safely and efficiently where it's needed.
