Three-phase ground-mounted transformer

Product Introduction

It uses a sealed corrugated tank design, effectively isolating external air and moisture, slowing the aging of the insulating oil, and ensuring stable operation, low energy loss, and a long service life. Thanks to its balanced operation, reasonable price, and easy maintenance, this series is widely used in urban and rural power grids, industrial and mining enterprises, renovation projects for old distribution networks, and in indoor and outdoor power distribution scenarios such as residential areas, factories, and small and medium-sized commercial facilities.

Technical parameters (customizable)

• Rated capacity: 10KVA-5000KVA, covering 18 common specifications from small to large, which can be selected flexibly according to the actual demand of users.

• Tap Switch: Off-circuit switch which should work when power is cut off, with simple operation, reliable contact, long service life and low failure rate; On-load tap switch can be configured according to user's needs to regulate voltage without power off in special occasions.

• Cooling: ONAN (Oil Natural Air Natural) is oil self-cooling mode, stable heat dissipation efficiency, simple structure, low failure rate, suitable for traditional load; ONAF (forced air cooling) can be selected as needed to increase the loading capacity by 20%-30%.

• Connection group: Dyn11/Yyn0, Dyn11 is the main connection mode, which has strong short-circuit resistance, stable voltage wave and good compatibility, suitable for most industrial and civil power distribution scenarios; Yyn0 is optional for small-capacity civil scenarios.

• Energy efficiency: ultra-efficient energy saving

Main Features

• Sealed, maintenance-free, leak-proof: The fully sealed corrugated tank structure without oil preservative can effectively isolate air and moisture, avoid the aging and dampness of the insulating oil, and no oil change and core lift in normal use, which is maintenance-free and leak-proof, which greatly reduces subsequent operation and labor costs.

• Stable structure, strong short-circuit resistance: The windings are wound with high-quality copper conductors, with reasonable design and strong fastening. The iron core and windings are tightly connected, which effectively withstands mechanical stress caused by sudden short circuits, prevents winding deformation and core displacement, and ensures stable and reliable operation.

• Low noise, reliable operation: Thanks to the optimized magnetic circuit design and high-quality core materials, the operating noise is controlled at 50-58dB(A), which meets the national standard, and the operation is stable and reliable, with a failure rate of ≤0.5% per year, which is suitable for most non-noise sensitive scenarios.

Application scenarios

• Urban and rural power grid: It is widely used in rural power distribution, urban public power supply, and the modernization and renovation of urban and rural power grid, which effectively improves the efficiency of power supply, reduces grid loss and ensures stable power supply for residents and public facilities.

• Industrial and mining enterprises: suitable for small and medium enterprises, mines, oil fields, chemical plants and other industries, providing stable and efficient power supply for production equipment, and adapting to general loads and continuous working conditions.

• Substations, box substations: As the main equipment for power distribution, it can be used with box substations, suitable for underground substations, outdoor power distribution stations and unattended power distribution points, ensuring stable operation and low maintenance costs.
