Insulating cylinders are mainly used for winding to improve the mechanical strength of winding and short-circuit resistance.

In the coil winding, Strips are used as internal support for the winding and to form internal axial cooling oil channels. Main strips: Rectangular strips, T shaped strips, Trapezoidal strips and other shaped strips. The Strips produced by our company have the following advantages: high mechanical strength, high electrical strength, and precise product dimensions.

A radial cooling oil passage and insulation between segments are formed in the coil winding. The wire turns of the winding rely on Spacers to transmit axial compression force for compression, so Spacers must have a certain degree of compression
The compressive strength should be as small as possible, but there should be some elasticity.

Wedge spacers Generally, the height of radial wire turns is adjusted at the transition or insufficient turns of the coil, as well as at the transposition of the spiral coil. Flatten the transition point to prevent the scissor opening, allowing axial pressure to be evenly distributed on the cushion block, and avoiding excessive force on the cushion block.
