Looking for fiberglass cable trays with complete specifications

Fiberglass cable trays are corrosion-resistant, non-conductive support systems ideal for harsh, industrial, and marine environments, available in ladder, trough, and solid-bottom designs with various resin types and load capacities.

Overview of Fiberglass Cable Trays

Fiberglass cable trays, also known as FRP (Fiber Reinforced Plastic) cable trays, are structural systems used to route and protect electrical and instrumentation cables. They are manufactured from fiber-reinforced polyester or vinyl ester resins, providing high corrosion resistance, long service life, and low maintenance compared with traditional steel trays . These trays are non-conductive, non-magnetic, and lightweight, making them suitable for environments where electrical insulation and reduced weight are critical .

Types of Fiberglass Cable Trays

1. Ladder Type: Features two side rails connected by transverse rungs. The open design allows excellent ventilation and heat dissipation, making it ideal for power cables and large-diameter control cables. Commonly used in power distribution, substations, and industrial plants .
2. Trough or Channel Type: Has a bottom plate with side rails, offering more protection while still allowing some ventilation. Suitable for control, communication, and instrumentation cables that require shielding from dust or falling objects .
3. Solid Bottom Type: Provides full protection for sensitive cables, often used in control wiring or lighter cable runs. Some trays include a flat fiberglass cover bonded to the bottom for additional protection .

Material and Resin Specifications

• Resin Types: Polyester and vinyl ester are common, with custom colors available. Vinyl ester offers superior chemical and UV resistance .
• Surface Treatment: A resin-rich surface veil enhances corrosion resistance and UV protection .
• Fire Ratings: Compliant with ASTM E-84 Class 1 and ASTM D-635 self-extinguishing standards .
• Mechanical Properties: Lightweight (1/3 the weight of steel) but strong, with high impact resistance and long span capability .

Environmental and Safety Features

• Corrosion Resistance: Resistant to chemicals, moisture, and marine environments .
• Non-Conductive: Reduces shock hazards and is safe for electrical installations .
• UV Resistant: Suitable for outdoor exposure .
• Fire Retardant: Meets industry fire safety standards .

Installation and Accessories

Fiberglass trays are easy to install, cut, and drill without welding. They can be used in vertical or horizontal runs, and accessories include bends, tees, reducers, covers, and supporting hardware . Pre-drilled sections simplify assembly, and some systems allow stainless steel banding for marine compliance .

Standards and Compliance

• NEMA FG1: Standard for fiberglass cable trays .
• ABS Approval: Suitable for marine applications .
• IEC and NEMA Testing: Ensures durability and load capacity .

Cable Support and Load Considerations

• Rung Spacing: Adjustable for light, medium, or heavy-duty applications .
• Load Capacity: Designed to meet safety factors of 1.5 times the allowable working load .
• Cable Types: Supports power, control, communication, and instrumentation cables, with options for solid or ventilated support depending on heat dissipation and protection needs . Fiberglass cable trays provide a durable, low-maintenance, and safe solution for routing cables in corrosive, industrial, and marine environments, combining strength, chemical resistance, and ease of installation.
