Cable Trays & Accessories
Cable trays are essential components in electrical and data communication installations. They provide support, organization, and protection for various types of cables. Let’s explore the different types of cable trays, their purposes, advantages, and disadvantages:
Ladder Cable Tray:
Purpose: Ladder cable trays consist of two side rails connected by rungs. They offer easy accessibility to cables from the top or bottom.
Advantages:
Convenient for tying down cables in non-horizontal runs.
Suitable for maintaining cable positions.
Disadvantages:
None specific to ladder cable trays.
Perforated Cable Tray:
Purpose: Perforated cable trays have a ventilated bottom with side rails. They provide more support to cables than ladder-type trays.
Advantages:
1.Enhanced cable support.
2.Efficient heat dissipation.
Disadvantages:
None specific to perforated cable trays.
Solid-Bottom Cable Tray:
Purpose: Solid-bottom trays are preferred for fiber-optic cable installations where drooping of cables may affect system performance.
Advantages:
Prevents cable drooping.
Shields against electromagnetic/radio-frequency interference.
Disadvantages:
None specific to solid-bottom cable trays.
Wire Mesh Cable Tray (Basket Cable Tray):
Purpose: Wire mesh cable trays are made of stainless steel wires welded together, forming a basket-like mesh. They are mainly used for low-voltage, telecommunication, and fiber optic cables on short spans.
Advantages:
Lightweight and durable.
Easy installation.
Disadvantages:
None specific to wire mesh cable trays.
Channel Cable Tray:
Purpose: Channel cable trays are small metal trays suitable for very small cable installations.
Advantages:
Economical support for short cable spans.
Space-saving design.
Disadvantages:
None specific to channel cable trays.
Materials:
Metallic:
Aluminium: Lightweight, corrosion-resistant, and excellent strength-to-weight ratio.
Steel: Provides electric shielding and has low thermal expansion.
