Description

Technical Field

[0001] This utility model relates to the field of mica tape technology, and more specifically, to a mica tape that integrates thermal protection and electrical insulation. Background Technology

[0002] Mica tape is an insulating material made by a mica tape machine. Mica tape has a wide range of applications. During the operation of electrical equipment such as motors and cables, a lot of heat is generated. The accumulated heat will accelerate the aging of the polymer materials in the main insulation, leading to a serious decline in mechanical properties and dielectric strength, and even causing insulation failure and safety accidents. In order to achieve a better protective effect, mica tape is usually used for insulation protection at the corresponding connection parts.

[0003] There are many types of mica tape on the market, but most mica tapes, being made of insulating materials, while providing insulation protection, suffer from poor thermal conductivity. When wrapped in multiple layers, this can hinder heat dissipation, impairing effective heat dissipation and enhanced electrical insulation. Therefore, we propose a mica tape that integrates thermal protection and electrical insulation. Utility Model Content
