Insulation paper is a composite insulation material that is often used when the motor winding is selected for enameled wire. The material is made of different types of insulation materials according to special adhesive bonding to make different insulation grades and heat resistance grades to meet the needs of motor windings with different performance requirements.

Insulation paper is a composite insulation material that is often used when the motor winding is selected for enameled wire. The material is made of different types of insulation materials according to special adhesive bonding to make different insulation grades and heat resistance grades to meet the needs of motor windings with different performance requirements.

In the production of motor windings, the insulation paper is used as the key to the insulation between the winding and the core slot, and the phase insulation of the three-phase motor winding. In engineering applications, insulating paper is cut into various shapes and sizes according to actual insulation requirements. When insulating paper is used as ground insulation and insulating material between inner layers of slots, it is usually cut into strips according to the size of iron core, and its size should meet the basic requirements of winding insulation and electrical gap. However, when insulating paper is used as phase insulation of three-phase motors, it is more used as end, its actual shape is determined according to the actual winding insulation needs.

The composite insulating material used for the winding of an insulating paper motor, whether as ground insulation or phase-to-phase insulation, must be able to withstand the ground insulation voltage and phase-to-phase insulation voltage during motor operation. In order to ensure that the insulation performance requirements of insulation paper do not deteriorate, in the production and processing of motor windings, composite insulation materials are not allowed to have negative effects such as delamination and foaming, and must be able to withstand the specified electric field impact.
