Types of fiberglass cable trays in Burundi

Fiberglass cable trays in Burundi are available in ladder, trough, and perforated types, designed for corrosion resistance, durability, and efficient cable management.Common Fiberglass Cable Tray Types

1. Ladder Type Fiberglass Cable Tray This type consists of two side rails connected by transverse rungs, forming an open structure that allows excellent ventilation and heat dissipation. It is ideal for power cables and large-diameter control cables, commonly used in industrial plants, substations, and power distribution systems. Ladder trays are easy to install and modify when adding or removing cables, and they come in various rung spacing and load capacities for light, medium, and heavy-duty applications . 2. Trough or Channel Type Fiberglass Cable Tray Trough trays have a bottom plate with side rails, offering more protection for cables while still allowing some ventilation. They are suitable for control cables, communication lines, and sensitive instrumentation circuits that require shielding from dust or falling objects. This type is often used in computer rooms, communication networks, and industrial automation systems . 3. Perforated Fiberglass Cable Tray Perforated trays feature holes along the bottom and sides, promoting air circulation to prevent overheating and ensuring optimal cable performance. They are widely used in commercial buildings, laboratories, and industrial facilities where heat dissipation and cable organization are critical. Perforated trays also provide lightweight, corrosion-resistant support for electrical and communication cables .

Material and Resin Options

Fiberglass cable trays are made from glass fiber reinforced polyester (FRP) or vinyl ester resin, providing high corrosion resistance, insulation, and long service life. For environments with strong acids, alkalis, or halogenated chemicals, vinyl ester resin (FR-VE) is preferred, while polyester fire-retardant resin (FR-P) is commonly used for general applications . Surface treatments such as flame retardant, UV protection, and anti-slip coatings can be applied depending on environmental requirements .

Applications in Burundi

In Burundi, fiberglass cable trays are used in power plants, substations, industrial plants, commercial buildings, and chemical facilities. They are favored for their durability, lightweight structure, and resistance to corrosion, making them suitable for both indoor and outdoor installations in harsh or humid environments .

Accessories and Fittings

Fiberglass cable tray systems in Burundi include bends, tees, reducers, covers, and support hardware to create complete cable management solutions. Standard lengths can reach over 6 meters, and trays are available in widths from 50 mm to 1000 mm and thicknesses from 1.2 mm to 3.0 mm . Overall, selecting the appropriate fiberglass cable tray type in Burundi depends on cable type, environmental conditions, load requirements, and installation location, ensuring efficient, safe, and long-lasting cable management.
