Polyethylene anticorrosive adhesive outer tape and polyethylene anticorrosive inner tape belt, polyethylene anticorrosive patch and anticorrosive primer together form polyethylene cold tape anticorrosive system. The polythene anticorrosive adhesive outer tape has the thicker base film and thin film, which mainly protects the corrosion and becomes a protective belt.
The varistor is represented in the circuit by the symbol "RV" or "R", and the voltage-sensitive nonlinear overvoltage protection semiconductor
The electronic components, we generally refer to the varistor as "VSR".
If the voltage applied to the varistor is much lower than the varistor threshold, the current through it will be small.
Fang said that it would be equivalent to a valve that is tightly shut down. If the voltage exceeds our UN, the electricity flowing through the varistor
The flow will surge, which is equivalent to opening a valve completely. This is the biggest feature of the function of varistor, we can
By using this feature, we can suppress the abnormal overvoltage that frequently appears in the circuit, and protect us by such new measures.
Electronic circuits and equipment are not subject to voltage damage and maintain normal operation to facilitate our production and life.
