Botswana FRP Cable Tray Specifications and Dimensions

FRP cable trays in Botswana are available in ladder and channel types, with standard widths from 100 mm to 1200 mm, heights from 50 mm to 150 mm, and lengths of 3000 mm or 6000 mm, made from corrosion-resistant, UV-stabilized fiberglass reinforced plastic.

Types of FRP Cable Trays

• Ladder Type: Composed of two longitudinal side rails connected by rungs, providing excellent ventilation and heat dissipation, suitable for multiple cable installations in industrial and building wiring systems .
• Channel/Perforated Type: Features a perforated bottom with integral side rails, often used in fire-proof, moisture-proof, dust-proof, and anti-interference applications. Covers can be flat or peaked for additional protection .

Dimensions

• Widths: 100, 150, 300, 450, 600, 750, 900, 1000, 1200 mm .
• Heights: Standard heights include 50 mm, 80 mm, 100 mm, 125 mm, and 150 mm; other heights are available on request .
• Lengths: Standard straight sections are 3000 mm and 6000 mm .
• Horizontal and Vertical Fittings: Tees, crosses, and risers are available with standard radii of 300 mm, 600 mm, and 900 mm .
• Reducers: Left, right, and straight reducers are supplied as needed .

Material and Resin Types

• Resin Options:
  • Polyester Resin: Standard, good UV and weather resistance .
  • Vinylester Resin: Enhanced corrosion and heat resistance .
  • Epoxy Resin: Excellent electrical insulation performance .

Accessories and Installation

• Coupler Plates: For connecting tray ends, elbows, tees, and reducers .
• Fasteners: Stainless steel SS 304 nuts, bolts, and washers for all connections .
• Covers: Flat or peaked covers for additional protection against environmental factors .
• Support Systems: Cantilever and trapeze junctions, splices, and support channels are available .

Standards and Performance

• Fire Retardant: Compliant with ASTM-E84 and BS 476 standards .
• Mechanical Properties: High glass content and continuous reinforcement provide excellent strength, stiffness, and resistance to permanent deflection .
• Environmental Resistance: UV protection, corrosion resistance, and chemical resistance ensure long-term durability in harsh conditions . These specifications make FRP cable trays suitable for industrial, commercial, and residential applications in Botswana, particularly where corrosion, UV exposure, and fire safety are critical considerations.
