Application

35kV power transformer is a medium-voltage transformer typically used in power distribution systems to step down or step up voltage levels for various applications. These transformers are crucial in the transmission and distribution of electrical power, particularly in areas where the voltage needs to be adjusted for further use in industrial, commercial, or residential settings.

Applications of 35kV Power Transformers:

Power Distribution Systems:

In power distribution networks, 35kV transformers are used to step down the voltage from 110kV or 220kV transmission lines to lower levels like 10kV or 6kV.

These transformers are placed in substations and are essential for efficient energy distribution over large areas, including urban and industrial zones.

Industrial Applications:

Many industrial facilities, such as factories, manufacturing plants, or large data centers, use 35kV transformers to power their heavy machinery, equipment, and internal electrical systems.

The medium voltage level ensures that equipment operates at optimal efficiency while preventing damage from overvoltage.

Renewable Energy Systems:

In renewable energy plants, like wind or solar farms, 35kV transformers are used to step up the voltage generated from renewable sources to the transmission level, allowing it to be fed into the main power grid.

Commercial and Residential Power Supply:

35kV transformers may be used in more localized power distribution where large-scale electricity needs to be delivered to commercial buildings or residential neighborhoods.

Electric Railways and Transport Systems:

They are also used in the electrification systems for railways, especially in regions where the rail system operates at medium voltages like 35kV for its traction power.

Specifications

  1. Type: outdoor
  2. Ambient temperature: max. temperature: +40℃; min. temperature: -30℃
  3.  Altitude: ≤1000m (temperature rise shall be corrected when>1000m)
  4. Relative humidity: ≤90% (25℃)
  5. Installation place: without corrosive gas and apparent fouling.

Construction:

35kV power transformers are generally three-phase to accommodate the standard three-phase alternating current (AC) systems used in power transmission.

The transformer core is typically made of silicon steel to enhance efficiency, and it is wound with copper or aluminum wire.
