DALON Electrical Bushing consist of a sintered bronze body. The main feature of Electrical Bushing is their porous design, which contains oil lubricant, which should be the viscosity decrease due to increasing operating temperatures due to friction, the oil leaks out. At higher speed, a lubrication wedge develops, which lowers the bushing's friction.

The powdered metallurgy process is a mass production process that can reduce costs to a level that can be startlingly low when compared to CNC machining. An added benefit of the sintered Electrical Bushing are the unique pores that are formed in the structure of the metal. These pores can serve as a reservoir for lubricant, providing a passage to the bearing surface. This unique feature adds the benefit of self-lubrication to many powdered metal bearings.

Storage of Electrical Bushing – These bearings must be stored in non-absorbing containers. Do not store in paper or cloth container. Do not store in cardboard boxes. The best containers are made of plastic or metal.

Supplementary Lubrication – Additional lubrication can be provided through the use of oil soaked felts, wicks, etc. or by periodic oiling. A unique advantage of this type of bearing is that it does not require any grooving or holes to distribute the oil across the bearing face due to the microscopic pores in the bearing material.

 

Over the years, our Electrical Transformer Bushing for 11kv Oil Immersed Transformer has received universal praise from our customers, which has laid the foundation for us to build a hundred-year brand. With honest management, excellent production quality, strict scientific management, good marketing concept and perfect inspection means, it has not only won a good reputation for the enterprise, but also brought high-speed development to the enterprise. And customized orders are acceptable.
