HIGH-VOLTAGE BUSHING INSULATOR Russian patent published in 2010 - IPC H01B17/28 

FIELD: electricity.

SUBSTANCE: invention relates to high-voltage technology. The high-voltage bushing insulator (1) has a conductor (2) and a core (3) which grips the conductor (2), wherein the core (3) is a sheet lining (4) saturated with electrically insulating binding material (6). The bushing insulator is characterised by that, the lining (4) has several openings filled with binding material (6). Preferably, the lining is cellular or latticed. Each cell can consist of fibres. The bushing insulator (1) can be a precision or a high-precision bushing insulator (1) with stabilising plates (5) placed inside the core. The binding material (6) used can be a resin with filler particles. The method of making the bushing insulator involves winding the sheet lining in form of spirals around the conductor (2) or around a mandrel with formation of several adjacent layers, and then saturation with electrically insulating binding material. A transformer, a distributing device and a high-voltage installation contain the bushing insulator (1) made as described above.

EFFECT: faster production of bushing insulators and provision for their safety during use.
