20-35 kV SC(B) Series Dry-Type Power Transformer

Description

Overview

This series of products are used to reduce the power supply of 35kV and 20kV power grid to 400V power distribution power supply or 10kV power transmission power supply directly for users. The main advantages are:
1. Reduce the land occupation and the construction of multilevel substation project, which has
significant social benefits.
2. Save the project investment and improve the economic benefit.

3. Reduce 10kV transmission and transformation links, so that operation and maintenance
costs significantly reduced.
4. The use of high voltage small current instead of low-voltage large current transmission, reduce line loss, reduce the operation cost of the line.

5. 35kV, 20kV power directly into the power supply center, effectively improving the reliability of power supply.

Features

• High performance, low loss, for the 9 series of products.
• Choose high quality silicon steel sheet, at the same time, reduce magnetic flux
• density greatly, reduce the magneto strictive quantity of silicon steel sheet in operation, reduce noise effectively.
• Optimize the structure of high voltage coil, improve the distribution of interlayer voltage and capacitance, greatly improve the product tolerance of overvoltage, and improve the distribution of electric field, so that the quantity of partial discharge is reduced further.
• The temperature control system and air cooling device can be configured to
• automatically start the fan cooling device when the load is too large, and effectively improve the overload capacity of the equipment.
