Bimetallic Parallel Groove Connectors, also known as Bimetallic PG Clamps. These state-of-the-art mechanical devices are specifically designed to connect and secure both aluminium and copper conductors in electrical systems. Bimetallic PG Clamps are the perfect solution for a wide range of applications, including overhead power transmission and distribution lines, substations, and various electrical installations. Below, we will delve into the numerous features and benefits that set these connectors apart from the competition.

Bimetallic Advantage

One of the unique characteristics of Bimetallic PG Clamps is the incorporation of two different metals in their construction. The connectors feature an aluminium side and a copper side, ensuring compatibility with a broader range of conductor materials. This bimetallic design not only facilitates easy connections between dissimilar metals but also helps to prevent galvanic corrosion, providing enhanced durability and longevity.

Material Quality and Composition

The Bimetallic Parallel Groove Connectors are expertly crafted using high-quality aluminium alloy and copper, which ensures excellent electrical conductivity and resistance to corrosion. The aluminium alloy used is 99.5% pure, which maintains high conductivity, significantly reducing power loss and enhancing overall performance. The copper side is made of high-quality, electrolytic copper, ensuring optimal electrical conductivity and compatibility with copper conductors.

Innovative Design

The innovative parallel groove design of these connectors guarantees secure and reliable connections between conductors. Each groove is meticulously contoured to match the shape of the conductor, ensuring a proper contact area and significantly reducing the chances of conductor slippage. Furthermore, the grooves are filled with an oxide inhibitor to prevent corrosion, further enhancing the electrical connection.
