Dry-type transformers in the oil and gas industry

Time：2025-03-22    Auther：ZTelec-www.ztelectransformer.com

Dry-type transformers play a crucial role in the oil and gas industry. The working environment in these industries is often extremely harsh, and there are stringent requirements for the reliability, safety, and adaptability of the equipment. Dry-type transformers have become an indispensable key equipment in the oil and gas industry due to their unique advantages, such as no need for oil immersion, simple maintenance, fire and explosion prevention, etc.

The oil and gas industry encompasses various stages, including exploration, mining, processing, and transportation. Many pieces of equipment in these links require a reliable power supply. However, the harsh working conditions—characterized by high temperatures, elevated humidity, and risks of flammability and explosion—pose significant safety hazards for traditional oil-immersed transformers. As a result, dry-type transformers have great safety hazards in these occasions. Dry-type transformers have become the first choice in the oil and gas industry because of their oil-free, pollution-free, and fire- and explosion-resistant properties. These transformers are widely used in critical locations such as drilling platforms, refineries, natural gas processing plants, and oil pipeline pumping stations, providing stable power support for various electrical equipment.

Technical features

1. No oil and no pollution

Dry-type transformers utilize air or other gases as cooling media and do not require oil immersion, eliminating the risk of pollution and fire caused by oil filling. This characteristic makes dry-type transformers a safer option in the oil and gas industry.

2. Fire and explosion prevention

Since there is no oil inside the dry-type transformer, there is no risk of explosion caused by oil filling. This characteristic is especially significant in environments that are flammable or prone to explosions, such as those involving oil and gas.

3. Simple Maintenance

The structure of dry-type transformers is relatively simple, lacking complex components like oil pillows and radiators, which makes maintenance is easier. At the same time, since there is no requirement for maintenance work such as oil sample testing, maintenance costs are also reduced.

4. Strong overload capacity

Dry-type transformers usually have strong overload capacity and can endure significant current surges for brief periods. This characteristic is particularly important in the oil and gas industry, where various equipment can generate large currents during startup or operation.

5. Environmental protection and energy saving

Dry-type transformers utilize advanced core materials and winding designs, resulting in low no-load and load losses. At the same time, since there is no need for oil immersion, environmental pollution caused by oil filling is also reduced.

Selection points

When selecting dry-type transformers for the oil and gas industry, the following points need to be considered:

Rated voltage and current: Select the appropriate rated voltage and current levels based on the actual requirements of the equipment.

Insulation level: Due to the challenging working conditions in the oil and gas industry, it is essential to choose dry-type transformers with higher insulation levels to ensure the safe operation of the equipment.

Cooling method: Select the appropriate cooling method according to the installation environment and operating conditions, such as natural air cooling, forced air cooling, etc.

Protection level: Select a dry-type transformer with a higher protection level to resist the impact of harsh environments on the equipment.

Brand and quality: Select a well-known brand and reliable quality dry-type transformer to ensure the performance and life of the equipment.
