What is insulator?
Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into high-voltage wire connection towers where many disc-shaped insulators were hung at one end. It ...Read more -
The difference between thermal silica gel and thermal grease
1. What are the characteristics of thermal silica gel (thermal potting glue)? Thermally conductive silicone is usually also called thermally conductive potting glue or thermally conductive RTV glue. It is a low-viscosity flame-retardant two-component addition type silicone heat-conducting potting...Read more -
