CNKEEYA, 25~167kVA, Single Pole Mount Transformer EU, single-phase overhead transformer: less transmission loss, full protection against overload and over-current, plus self-protection functions. It ensures stable power for households, industry, communications, agriculture and grid operations — compact, easy to operate flexibly and simple to maintain.

Product overview       

The single - phase overhead transformer from CNKEEYA reduces electric loss during transmission and has over - load, over - current and self - protection functions, ensuring stable power supply for household, industrial use, communication use, agricultural production use and grid operation. It is compact, easy to operate flexibly and simple to maintain.

Features

 Single - phase transformers are widely used as distribution transformers in Western developed regions, Southeast Asia, and the Americas. Single - phase transformers offer distinct advantages in decentralized power - supply distribution networks. By shortening low - voltage distribution lines, they reduce line losses and improve power quality.

Designed with a high - efficiency wound iron - core, they feature pole - mounted installation, compact size, and low infrastructure investment. By reducing the low - voltage power - supply radius, they can cut low - voltage line losses by over 60%. With a fully - sealed structure, they have strong overload capacity, high - reliability in continuous operation, easy maintenance, and a long lifespan.

 Applicable to rural, remote, and scattered - village power grids, as well as agricultural and lighting applications, they can also be used in pole - mounted distribution lines for energy - saving in railway and urban power grids. They can operate in single - phase or three - set combinations.

1. Tap Changer

Function: Adjusts the turns - ratio of transformer windings to change the output voltage. Advantage: Enables voltage fine - tuning to adapt to grid fluctuations or load requirements.

2. Primary Bushing

Function: Insulates and leads the high - voltage windings from the transformer's interior to the external circuit. Advantage: Ensures safe high - voltage transmission by providing reliable insulation.

3. Arrester

Function: Protects electrical equipment from over - voltage caused by lightning or switching operations. Advantage: Safeguards equipment insulation and reduces the risk of damage from transient over - voltages.

4. Pressure Relief Device

Function: Releases excessive internal pressure in the transformer when faults generate a large amount of gas. Advantage: Prevents the transformer tank from exploding due to high pressure, enhancing safety.

5. Secondary Bushing

Function: Insulates and leads the low - voltage windings from the transformer's interior to the external circuit. Advantage: Facilitates safe low - voltage power transmission with good insulation performance.

6. Core

Function: Serves as the magnetic path for electromagnetic induction in the transformer. Advantage: Enables efficient transfer and transformation of electrical energy in the transformer.
