Description

100 kVA 35 kV Pure copper Dry Type Transformer High-Voltage Dry-Type Power Distribution Equipment

In traditional power supply scenarios, oil-immersed transformers have shortcomings such as oil leakage and weak fire resistance, making them unsuitable for many sites due to regulatory restrictions. Many projects have compact sites, making it difficult to allocate sufficient fire isolation areas, resulting in a trade-off between equipment operational safety and site planning. We introduce the 100 kVA 35 kV Pure copper Dry Type Transformer, which utilizes an optimized insulation system with an all-copper winding structure to avoid oil-related safety hazards. The equipment is less likely to generate pollutants during operation, adapts to stringent site standards, and can be installed nearby with a high-and-low voltage switchgear to stably perform power conversion tasks. It is often used in conjunction with an Electric Power Converter and is widely deployed in industrial park power supply and Combined Photovoltaic Substations. It can also be integrated into box-type substations to provide reliable transformer support for small and medium-sized substation units.

This Dry Type Transformer uses pure copper windings as its conductive core, ensuring stable conductivity and excellent temperature rise control under fluctuating load conditions. The entire unit uses no insulating oil, exhibiting outstanding fire-retardant properties, making it suitable for both indoor and underground power distribution spaces. Compared to oil-immersed equipment, daily pollution emissions are significantly reduced, meeting the stringent environmental and safety requirements of urban infrastructure and new energy power plants. With a rated capacity of 100 kVA and a voltage level of 35 kV, it is suitable for small to medium-sized substations, providing stable output voltage and effectively ensuring continuous and stable operation of downstream loads. Long-term operation reduces the frequency of downtime maintenance, lowering overall project maintenance costs.

Product Features

1.Pure Copper Winding Configuration: Lower conductivity losses, controllable temperature rise during prolonged full-load operation, extending equipment service life.

2.Oil-Free Safety Structure: The Dry Type Transformer itself contains no flammable media, eliminating the need for large oil storage facilities and allowing for greater flexibility in site layout.

Tips

1.The equipment installation location should ensure natural ventilation to avoid prolonged heat accumulation in a sealed environment and maintain efficient heat dissipation.

2.Regularly check the tightness of the wiring terminals to reduce losses and safety hazards caused by contact heating.
