Product Description

Specification

• Highest voltage for equipment can be up to 13.2 kV.
• Protects from Induced Overvoltage
• No maintenance is required
• No special grounding required
• The outer air gap has been fixed before installation, and the components have been pre-assembled
• Protection against: IOV
• Only 1 product per pole is required
• Products are installed with phase alternation (А -> B -> C)
• Definitely great use and the highest possible reliability
• Line Protection Device has been designed to ensure the most effective protection from indirect strokes. This device is able to perform as highly effective lightning protection system, providing secure power network operation in 80% of such issues.
• In order to protect sensitive equipment, such as pole-mounted transformers (PMT), conventional metal oxide surge arresters still must be used

Operational Principle

• Ensuring a high ability to discharge excessive energy of an overvoltage in the surrounding atmosphere
• The induced overvoltage will create an electrical power arc between the terminal electrode of a MLPD and the conductor clamp on a line. First, the arc will be divided into a series of small arcs by a series of discharge chambers, and then quickly extinguished when the oscillating current of the grid exceeds zero.
• Make full use of the grounding resistance between two towers, each tower only needs to install one product
• It is used for the protection of overhead line induced lightning overvoltage, which is more cost-effective than traditional solutions.
