Composition principles and uses of internal components of zinc oxide arrester manufacturers
Principle of gapless metal zinc oxide arrester
A lightning arrester composed of nonlinear metal oxide resistors connected in series and/or parallel without a parallel or series discharge gap.
Nonlinear metal oxide resistor
The main working parts of zinc oxide arrester. Due to its nonlinear volt-ampere characteristics, it exhibits low resistance during overvoltage, thus limiting the voltage between arrester terminals, but exhibits high resistance under normal power frequency voltage (nonlinear metal oxide resistor, hereinafter referred to as resistor).
Zinc oxide arrester internal voltage equalization system, cold shrink cable terminal
A voltage-equalizing impedance connected in parallel to a resistor or a group of resistors is mainly a voltage-equalizing capacitor to control the voltage distribution along the resistor columns.
Zinc oxide arrester voltage equalizing ring
A metal component, usually in the shape of a circular ring, used to improve the voltage distribution of a lightning arrester under electrostatic fields.
Zinc oxide arrester proportional unit
A surge arrester component assembled as required, which must be representative of the characteristics of the entire arrester for a specific test. Arrester proportional units are not necessarily arrester elements.
Zinc oxide arrester components
A complete arrester component assembled can be connected in series and/or parallel with other components to form an arrester with a higher rated voltage and/or higher nominal discharge current.
Zinc oxide arrester pressure relief device, European style cable joint.
A device used to release the increased internal pressure caused by internal faults of the arrester to prevent explosion of the arrester.
