KBSG series Mining Flameproof Dry-Type Transformer

Product Detail

Product Introduction

The KBSG series mining flameproof dry-type transformers innovatively adopt active heat dissipation pipes, which slow down the aging rate of insulating materials and enhance the reliability and stability of the products. They are suitable not only for underground mines with gas, coal dust and explosion hazards, but also for gas-containing tunnel mining, mobile working faces of non-coal mines and other environments.

Feature

Low Loss and Low Noise：Partial discharge quantity is less than 5pC, which improves product reliability with low noise.
Efficient Heat Dissipation：Additional active heat dissipation pipes and an innovative zoned heat dissipation structure enhance the transformer's heat dissipation performance, slow down the aging rate of insulating materials, and strengthen the product's reliability and stability.
Effective Flame Retardancy：The arc-shaped corrugations on the top and non-closed side edges prevent coal dust accumulation, achieve effective flame retardancy, and improve safety.
Excellent Flameproof Performance：The cylindrical flameproof enclosure enhances shell strength; the shell can withstand a pressure of 1MPa, with superior flameproof performance.
