Principles and uses of internal components of zinc oxide arrester manufacturers

The principle of non-gap metal zinc oxide arrester

Arresters with non-linear metal oxide resistors in series and (or) in parallel without parallel or series discharge gaps.

Non-linear metal oxide resistors

The main working parts of zinc oxide arrester. Due to its non-linear volt-ampere characteristics, it exhibits low resistance during overvoltage, thereby limiting the voltage between the arrester terminals, and exhibits high resistance under normal power frequency voltages (non-linear metal oxide resistors, hereinafter referred to as resistors).

Zinc oxide arrester internal voltage equalization system, cold shrinkable cable terminal

The voltage equalizing impedance connected in parallel to a piece or a group of resistors is mainly a voltage equalizing capacitor to control the voltage distribution along the resistor plate column.

Zinc oxide arrester equalizing ring

A metal part, usually in the shape of a ring, used to improve the voltage distribution of the arrester under an electrostatic field.

Zinc oxide arrester proportional unit

A lightning arrester component assembled as required, for a particular test, it must be able to represent the characteristics of the entire arrester. The arrester proportional unit is not necessarily an arrester component.

Zinc oxide arrester components

An assembled complete arrester component can be connected in series and (or) in parallel with other components to form an arrester with a higher rated voltage and (or) higher nominal discharge current.

Zinc oxide arrester pressure release device, European-style cable connector.

A device used to release the increased internal pressure caused by the internal failure of the arrester to prevent the arrester from exploding.
