35KV grade epoxy cast dry transformer

Product introduction

This series of products is used to directly reduce the 35kV grid power supply to 400V distribution power supply, or other medium and low voltage power supply for the user power supply, this series of products due to significant advantages, more and more projects are used. Its main advantages are as follows:
1.Reduce the floor area and multi-stage power transformation project construction, with significant social benefits
2.Save project investment and improve economic efficiency; 3. Reduce 10kV power transmission and transformation links, so that the operation and maintenance costs are significantly reduced,4. Use high-voltage small current instead of low-voltage large current transmission, reduce line losses and reduce line operating costs;
5.35kV directly into the load center, effectively improve the reliability of power supply.

Description

Product/performance characteristics

SCB10 series 35kV non-excitation voltage regulation dry transformer produced by our company is a low-loss product, which meets the latest national standards and has the following characteristics:

High performance, low loss, replacement products for other series;
The selection of high-quality silicon steel sheet, while greatly reducing the magnetic flux density, reduce the operation of silicon steel sheet hysteresis amount, effectively reduce noise;
Optimize the high-voltage coil structure, improve the distribution of interlayer voltage and capacitance, greatly improve the impact ability of the product to withstand atmospheric overvoltage and operating overvoltage, and also improve the electric field distribution, so that the product offload is further reduced.
Temperature control system and air cooling device can be configured to automatically start the fan cooling device when the load is too large, effectively improving the overload capacity of the equipment.
