Frequently Asked Questions
Technical Questions
Environmentally Friendly: These products do not require oil or other potentially hazardous liquids for insulation.
Reduced Maintenance: Solid insulation materials reduce the likelihood of leaks or degradation, lowering maintenance costs.
Safety: Dry-type products are safer because they eliminate the risks associated with oil-based equipment.
Compact Design: They are often more compact and lighter than oil-based alternatives, which can make installation easier and reduce space requirements.
Reliable Performance: Dry-type components offer long-lasting, reliable performance under typical operating conditions.
Choosing the right bushing depends on several factors:
Voltage Level: Ensure that the bushing is rated for the voltage you are working with.
Current Capacity: Make sure the bushing can handle the amount of current flowing through it.
Environmental Conditions: Consider factors like humidity, temperature, and exposure to chemicals when selecting the material of the bushing.
Type of Equipment: Whether you are using a transformer, GIS system, or switchgear will also influence your choice.
Dry-type bushings are typically made from high-quality materials such as:
Epoxy resin: Often used for insulating materials due to its strong dielectric properties and durability.
Porcelain or ceramic: These materials provide excellent insulation and are resistant to high temperatures.
Composite materials: Some bushings use a combination of polymer and other materials to improve strength and resistance to environmental factors.
The lifespan of dry-type power products can vary depending on the quality of materials, environmental conditions, and the level of maintenance. However, these products are typically designed to last 20-30 years with proper care and maintenance.
