Description

Technical Field

[0002] In the resistor manufacturing process, quartz sand is mixed with conductor materials in a specific ratio to form a resistive layer. The addition of quartz sand effectively increases the resistance value and dissipates power by impeding current flow. The application of quartz sand in resistors not only improves the precise control of resistance values ​​but also enhances the durability and stability of the resistors. Current varistor filling methods involve manually pouring quartz sand into the resistor, which is slow, resource-intensive, and cannot meet the demands of automated production. Utility Model Content
