Type of PG clamps you should know about

 One crucial component in electrical systems is the Parallel Groove (PG) Clamp, which is widely used in industrial and residential electrical applications. PG clamps, often known as Parallel Groove clamps, connect conductors and wires. The operation is relatively straightforward: the conductors are put into the grooves, and the clamp is secured by tightening the bolts, ensuring the conductors stay safely connected without contacting them directly.

 

 

Axis has been supplying the best quality PG clamps for over 30 years, and their applications are in the electric field.

 

Let's dive into the PG clamp types and their applications!

 

The Types of PG Clamps

There are three PG clamps: conductor terminals for aluminum and steel, terminals and connectors for corrosion-resistant kinds, and PG clamps with copper cable connectors. Thus, the main types differ by the materials with which the conductors are connected in the mainline.

The most common types of these clamps are:

Aluminum PG Clamp

Aluminum PG clamps are most commonly used with aluminum conductors. They are also suitable for low- and high-voltage applications, ranging up to 220 kV. These clamps are made to connect two aluminum conductors in parallel, keeping them securely attached. Aluminum clamps can come in one-, two-, or three-bolt varieties depending on the size and current-carrying capacity. One should use these clamps if both conductors are aluminum. Nevertheless, if one of the conductors is copper, one must apply a Bimetallic PG Clamp to prevent corrosion from two distinct metals contacting each other directly.

Bimetallic PG Clamp

Bimetallic PG clamps should be applied when dealing with aluminum and copper conductors. This clamp prevents two separate metals from contacting again due to the possibility of corrosion. These two metals are joined by friction welding and forging in one of the grooves. Once again, like aluminum clamps, bimetal clamps can come in various sizes and bolt types, depending on the conductor's capacity.

 

Brass PG Clamp

Brass PG clamps are intended for earthing and lightning protection. They are constructed from brass or bronze and will successfully keep copper conductors connected. In certain situations, proper earthing and grounding are required, making brass clamps the most suitable solution.

When selecting a PG Clamp from a reliable PG clamp manufacturer, it's essential to consider a few key factors that impact its quality and performance:

Thickness: The clamp's thickness determines its current-carrying capacity. If it's too thin for the application, it may not properly handle the mechanical stress and electrical load, leading to overheating and potential failure.

Corrosion Resistance: Corrosion weakens the clamp's mechanical strength and increases electrical resistance, which can result in overheating and system failure. Tin plating, also known as tinning, is a technique used to prevent corrosion, ensuring long-term durability and electrical conductivity.

Summing Up

PG clamps are critical components in electrical systems, ensuring power distribution and transmission safety and efficiency. Whether it's an aluminium PG clamp, bimetallic PG clamp, or brass PG clamp, each serves a distinctive purpose based on the application.

Assuring you pick the correct type of PG clamp and verifying its quality with a trusted lugs manufacturer in India or cable lugs manufacturer is vital for maintaining electrical safety.
