Bi – Metallic Connector

Bi - Metallic Connector

A Bi-Metallic Connector used in lightning protection and grounding systems is a specialized component designed to create a reliable electrical connection between two different metals in order to facilitate the dissipation of electrical current and provide protection against lightning strikes.

Product Details​​

Product Overview

  • Standard: IEC 62561 / TCVN 9385

  • Material: Copper – Aluminum

Product Details

The bi-metallic connector is typically constructed with two metal plates or lugs made of different metals, such as copper and aluminum. The metals used are carefully chosen for their electrical conductivity and compatibility. Copper is an excellent conductor of electricity, while aluminum is lightweight and cost-effective.

The connector is installed at junction points where different metal components meet, such as the connection between copper conductors and aluminum grounding rods. It ensures a reliable and low-resistance connection between the dissimilar metals, allowing for efficient dissipation of electrical current during a lightning event.

By using a bi-metallic connector, the potential issues associated with galvanic corrosion between dissimilar metals can be minimized. Galvanic corrosion occurs when two different metals come into contact with each other, resulting in accelerated corrosion. The bi-metallic connector helps mitigate this by providing a stable and corrosion-resistant connection point.
