Problems solved by technology

[0003] However, in extreme environments such as high humidity and even rain, there is indirect electrical conduction between the heating module and the shielding module, and the insulation resistance cannot meet the normal functional requirements of military equipment.

At the same time, in order to improve the impact resistance of electric heating shielding glass, it is usually achieved by adding layers of glass and polymer film, which will inevitably cause the loss of overall size and weight
