Product overview

The overvoltage protection products for overhead insulated lines mainly include 10kV line lightning protection overvoltage protectors and 10kV overhead insulated line overvoltage protectors?. These products are mainly used to prevent damage to overhead insulated lines caused by overvoltage caused by lightning strikes, ensuring power supply.

The normal operation of the system.

The 10kV line lightning protection overvoltage protector is designed for 10kV lines, and its main components include installation brackets, zinc oxide current limiting elements, drainage rods, and puncture clamps. This product is formed by the series gap between the drainage ring and the insulated wire, and the cooperation of the current limiting element

Together, it effectively cuts off the continuous current of the power frequency, avoids insulator flashover or breakdown, thereby protecting the overhead insulated line and preventing wire breakage accidents.

The overvoltage protector for 10kV overhead insulated lines is designed to prevent direct lightning overvoltage or induced overvoltage caused by lightning strikes, and to prevent insulator flashover or breakdown. Its main features include:

Excellent protection features: Through the synergistic effect of the series gap formed between the drainage ring and the insulated wire and the current limiting element, the power frequency continuous current is effectively cut off, preventing the insulated wire from breaking after lightning strikes?.

Special mechanical structure: including load-bearing skeleton, buffer layer, etc., to ensure that the product can withstand large mechanical stresses, reliable sealing, and explosion-proof.

Safe and reliable: The product operates safely and reliably, without maintenance. Even if the protector is damaged due to abnormal conditions, it will not affect the insulation coordination of the line, ensuring the safe operation of the power system.

Installation and maintenance recommendations

Installation: Install in parallel with the insulator. First, unscrew the bolt on the upper end of the current limiting element, press the pressure plate positioning pin on the stainless steel drainage ring into the positioning hole on the upper end of the current limiting element, tighten the bolt and tighten it. Then tighten the current limiting element onto the connecting piece.

Maintenance: It is recommended to increase the frequency of line patrols during thunderstorms. If any abnormalities are found in the appearance of the product or the drainage ring (such as damage, cracking, or signs of electrical corrosion on the outer cover of the current limiting element), please replace it immediately.
