Understanding the Importance of GI Trunking in Electrical Installations: A Comprehensive Guide

When it comes to electrical installations, keeping your cables safe and organized is of paramount importance. Just like how a well-organized closet keeps your clothes in order and easy to find, trunking does the same for cables. In this comprehensive guide, we’ll delve deeper into the importance of GI trunking in electrical systems. Furthermore, we’ll also explore its different types, uses, advantages, and installation methods. 

What is Trunking in Electrical Installation?

If you are seeking a methodical approach to cable management, electrical trunking has got the answers. It is a necessary part of electrical installations. 

In electrical systems, trunking is a conduit or an enclosure that is used to contain and protect the electrical cables. This enclosure guarantees accessibility, organization, and safety. Trunking normally has a square or rectangular structure, including at least one removable side, which makes cable installation and maintenance simple. 

Importance of Trunking

Now, you must be wondering what the importance of trunking in electrical installations is. 

Trunking basically protects the electrical cables from various factors, such as moisture, dust, and physical damage. This extends the cables’ lifespan and lowers the chances of electrical risks. By enclosing electrical cables in trunking systems, you can promote a safer and more orderly work environment and minimize the risk of potential tripping. 

In addition, trunking also makes it easier for electrical currents to be distributed inside buildings and machinery. Thereby ensuring a reliable power supply while following safety regulations. Trunking is a vital part of improving the functionality and reliability of electrical systems in residential, commercial, and industrial settings. 

Types of Trunking in Electrical Installation

Trunking in electrical installations is done in various ways. These divisions are made based on the material used and the type of trunking provided. Let’s explore some of the commonly used types of trunking in electrical installations in detail. 

The following are the common types based on the material used.

1. Metallic Trunking

Metallic trunking is a type of trunking that is made from materials such as steel or aluminum. This sort of trunking is used in factories, warehouses, and commercial buildings as metallic trunking offers durability, strength, and robustness. 

Metallic trunking provides excellent protection for cables and shields them from physical damage and environmental factors. 

2. GI Trunking

GI trunking falls under a broader section of metallic trunking. It is also known as Galvanized Iron trunking. It is made from galvanized iron sheets coated with zinc. The zinc coating provides corrosion resistance. This sort of trunking offers cable protection against mechanical damage, moisture, and environmental factors.  It is suitable for both indoor and outdoor use. 

Since GI Trunking provides durability, longevity, and resistance to corrosion, it is a preferred choice in industrial and commercial projects.

3. PVC Trunking

PVC trunking is made from a material called polyvinyl chloride which is flexible and lightweight. This sort of trunking is easy to install and provides adequate protection. It can be used to protect cables in houses, offices, and small businesses. 

PVC trunking is known to be versatile and aesthetic. It is popularly used in places where aesthetics are important. Plus, it also provides protection against dust, moisture, and minor impacts. It is better suited to be used indoors where you don’t have to worry about durability.

Based on the type of trunking provided, the following are the commonly used types:

4. Outdoor/External Trunking

As indicated by the name, outdoor or external trunking is especially designed to be used outdoors, where cables are exposed to harsh environmental conditions. This sort of trunking is made from weather-resistant material such as galvanized steel or heavy-duty PVC.  Due to its composition, it can provide resistance against moisture, UV radiation, and temperature fluctuations. 

This type of trunking is commonly used in outdoor electrical installations, construction sites, and industrial environments where cables are exposed to harsh elements.

5. Multi-Compartment Trunking

Multi-compartment trunking is a trunking system in electrical installations that uses multiple compartments. It is a very safe and efficient trunking system as the multiple compartments allow the division of different types of cables. Using this sort of trunking you can easily utilize separate compartments for different cables such as power, data, communication, etc. 

If your installation requires strict segregation of cables for safety or regulatory reasons multi-compartment trunking is the way to go. this sort of trunking is commonly used in health facilities, data centers, and commercial buildings. 

6. Bus-bar Trunking

Industrial premises and power plants require the distribution of high currents. Bus-bar trunking is specifically designed to provide cost-effective and reliable distribution of high-current. It makes the use of following two compartments. 

1. Insulated conductor or bus-bars
2. Protective trunking enclosure

The protective trunking enclosure is like a box that houses the insulated conductors. Both of these parts work together to distribute power efficiently, with minimal voltage drop or energy loss. 

This type of trunking is commonly used in factories, power plants, and large commercial buildings for the distribution of high-current.

Advantages of Trunking

The importance of trunking in electrical installations cannot be overstated. It offers various advantages in electrical systems. 

• Trunking keeps cables safe from damage and accidents.
• It reduces the risk of electrical shocks and short circuits.
• Trunking cables keep them organized and easily identified. 
• It is easily customizable to suit different needs and spaces. 
• It is easy to install and saves time and effort.
• Trunking can be used in various places whether indoors or outdoors such as industries, offices, commercial spaces, homes, or factories. Plus, it can be used with various cables.
• Trunking meets both safety and legal requirements.
• It gives easy access to cables for maintenance and inspection. 

The Role of GI Trunking in Industrial Settings

GI trunking is a preferred way of trunking in industrial settings as it ensures durability, longevity, and resistance to corrosion. Let’s explore the role of GI trunking in industrial settings in detail.

• The Zinc-coated iron sheets in GI trunking provide resistance to corrosion and rust. Allowing for durability in industrial settings where exposure to moisture and chemicals is very common. 
• This protects cables from damage caused by heavy machinery and high-traffic areas.
• GI trunking also provides fire resistance and reduces the risk of electrical fires.
• Simple organization of cables allows for easy access for repair and inspection.
• GI Trunking also provides a shield against electromagnetic interference, which ensures the reliable performance of electrical systems. 
• This is designed to withstand extreme temperatures and outdoor exposure, making it a perfect fit for industries.
• It meets safety standards and regulations.
• GI trunking can also be customized to suit unique industrial requirements.

Maintenance of GI Trunking

To ensure optimal performance, longevity, and safety of GI trunking in electrical installations, Industries have to follow a few maintenance guidelines.

• Keep a close eye on your trunking for any loose parts or damage to prevent problems. 
• It is essential to clean your trunking systems regularly, to avoid any dirt deposits.
• To keep your trunking system secure continuously check and tighten bolts and connectors. 
• Use special coating in wet areas to prevent corrosion of your trunking system.
• Ensure that the cables are neat, secure, and undamaged. 
• Replace any damaged parts of your trunking system to ensure safety and longevity. 

Conclusion

Trunking is essential to keep your electrical systems safe, organized, and efficient. This helps to extend the lifespan of your cables, which is why trunking has various applications from homes, offices, and small businesses to factories, industries, and commercial sites.
