Feature 

FRP box-type cable tray is a composite structure between trough type and ladder type, with the following characteristics:

• Semi-enclosed design: the bottom is a ladder structure, and the upper part is equipped with an openable cover
• Multi-functional combination: it has both the protection of the trough type and the heat dissipation of the ladder type
• Modular design: standard section + special section (horizontal bend, vertical bend, variable diameter straight, etc.) combination
• Reinforced structure: key parts are thickened and reinforced

Installation points and precautions

• Bracket system: It is recommended to use fiberglass composite bracket, with a span of no more than 2.5m
• Connection method: Use internal connection plate + stainless steel bolts for fixing, and install rubber sealing strips at the joints
• Grounding system: Set a grounding point every 20m, and the grounding resistance is ≤4Ω
• Expansion joint setting: When the straight section exceeds 50m, a thermal expansion and contraction compensation device should be set
• Fire prevention measures: Fireproof partitions should be used to block when crossing fire partitions
