ABSTRACT:
The electric isolator (1) is manufactured from a support (2) made of laminated material and a continuous band made of elastomeric material (3) wound in several contiguous successive turns around the support on an outer face (20) thereof so as to make an isolating coating in the form of a plurality of annular flanges (16, 17, 18). The continuous band is profiled so as to have, in section, a basis used as a contact surface with the support outer surface, an upper face provided with at least one flange extending transversally to the basis, a first and a second side surfaces which continue the basis by forming a certain angle therewith. The first side surface of the band is brought directly in superposing contact with the second side surface of the band during the winding of the band in turns and while leaving the elastomeric material raw at the level of the first and second side surfaces and a pressure is applied towards the support on at least a portion of the upper face of the band along a slot (10) created between the first and second side surfaces so as to assemble the two surfaces. Thus, the outer surface of the elastomeric coating has no joint between the annular flanges (16, 17, 18).
