Product Description

ROOQ Electric Group Co.,Ltd. is a technology-oriented enterprise specializing in R&D, production, sales and services of power transformers, HV/LV switch cabinets and related products. Our factory can offer the complete range of power distribution transformer.

Fully sealed oil-immersed distribution transformer

Product Description

 

The three-phase oil-immersed distribution transformer produced by our company adopts a new insulation structure to improve the short-circuit resistance.
The core is made of high quality cold emulsion silicon steel sheet.The high voltage windings is made of high quality oxygen-free copper wire and adopts multiplayer cylinder structure.All fasteners are specially loose-proof.

Advantages

1 - Low loss, low noise, low partial discharge, low temperature rise and energy-saving.

2 - Adopt the latest insulatoin structure.

3 - Excellent anti-short-circuit ability.

4 - Using efficient heat sinks, it is possible to increase the number of corrugated sheets or sheet radiators, cooling fans, and motors.
 

5 - More stable internal structure, no malfunctions during transportation.

 

High-quality materials
1 - Choose the oxygen free copper wire with lower resistivity,and after a series of additonal surface treatment,more smooth,no burrs,sharp corners,so that the transformer load loss is lower,the electricial performance is more reliable.

2 - Choose high-quality silicon steel sheets,and with the improvement of performance  level,use silicon steel sheets with lower unit loss to reduce the no-load loss of transformers.

3 - Choose high-quality laminated wood insulation components that never crack, even under the action of short-circuit current, they remain intact.

4 - Using transformer oil that has undergone deep filtration results in lower levels of water, gas, and impurities, making transformer operation more reliable.

5 - Choose high-quality rubber sealing materials to effectively prevent aging and eliminate leakage.

6 - All raw materials undergo quality inspection, and all raw material manufacturers undergo strict review in accordance with the national standard ISO9000.

Quality Inspection

The important nodes in the manufacturing process of the product will undergo professional and strict quality inspection. After the final production is completed, the company's transformer intelligent testing center will conduct a comprehensive inspection of the product to ensure that all products are qualified.
