How Many Types of Cable Trays?

Cable trays are crucial in cable management, providing organized electrical and communication wiring pathways. They are available in various materials and configurations to suit industrial, commercial, and residential applications. Understanding the types of cable trays and their installation techniques helps select the best option for specific needs.

Types of Cable Trays by Material

• Zinc-plated galvanized steel cable trays

Galvanized steel cable trays offer excellent corrosion resistance and durability. The zinc coating prevents rust formation, making them ideal for industrial settings, outdoor applications, and harsh environments.

• Stainless steel cable trays

Stainless steel trays are highly resistant to corrosion, chemicals, and extreme temperatures. They are commonly used in food processing, pharmaceuticals, and marine industries where hygiene and durability are essential.

• Aluminum ladder cable trays

Aluminum ladder cable trays are lightweight, corrosion-resistant, and easy to install. They provide superior ventilation, allowing cables to remain cool. They are widely used in aerospace, offshore platforms, and power plants.

• Fiber Cable Tray

The Fiber Cable Tray—Straight Channel is designed to route and protect fiber optic and high-performance copper cabling in data centers, enterprises, central offices, and mobile switching centers. It provides a complete raceway solution, featuring a wide range of channels, transitional fittings, drops, and support structures, ensuring flexibility and adaptability for any installation environment.

• Adhering to NEC and NEMA guidelines for safe installation.

FAQs

What is the standard for cable trays?

Cable trays must comply with NEC (National Electrical Code) standards, NEMA (National Electrical Manufacturers Association) ratings, and UL certifications to ensure safety and efficiency.

What are the five basic cable tray fittings?

The five common fittings that we offer include:

1. Cable tray elbows, also known as splice connection hardware, are used to change direction.

2. Wall support brackets assist in stabilization. 

3. Tray dividers (reducers) and cable routing options help in organization. 

4. Tray covers provide additional protection for cables. 

5. Floor supports are essential for stability.

What is the difference between wireways and cable trays?

Wireways are enclosed pathways primarily used for protecting cables in small-scale applications, while cable trays offer open and flexible support for larger installations.

How do I choose a cable tray?

Consider factors such as load capacity, material, environmental conditions, and industry regulations when selecting a cable tray.

What is the difference between a cable ladder and a cable tray?

Cable ladders provide higher load capacity and better ventilation, while cable trays offer solid-bottom or perforated options for additional cable protection.

What is the difference between a cable tray and a raceway?

Cable trays are open structures that allow easy cable routing, while raceways are fully enclosed, offering greater protection but less accessibility.

What is the best material for cable trays?

The best material depends on the application:

• Galvanized steel for heavy-duty, industrial environments.

• Stainless steel for corrosion resistance.

• Aluminum for lightweight durability.

Cable trays must adhere to key regulations for safety and reliability provided by NEC, NEMA, UL, and OSHA that ensure cable tray durability, proper installation, and workplace safety.

Choosing the right cable tray is essential for efficient cable management. Whether you need high-strength galvanized steel, corrosion-resistant stainless steel, or lightweight aluminum ladder trays, understanding their properties will help you make the best decision.
