Structure
A. Steel Shell: Groove of Fire-Resistant Cable Tray is made of a cold-drawn forming (make the groove has higher bearing capacity), cable tray cover is automatic closed type double shield, the upper cover is fire-proof and dust-proof, the down cover is convulsions (upper open air ventilation which makes the good breathability in normal operation of the cable );
Interlayer between double cover plate is low temperature nylon sleeve supporting which would
Automatically melting in case of high temperature gas or flame. Then the upper cover plate fall down automatically, two layers of heavy plate be together into confined Spaces, prevent flame and high temperature gas go inside. After installation, joint can reach perfect airtight and protection level can be up to IP54.
B. Inner material: Fire-poof rock wool is Aluminum silicate rock wool, and its thickness is 16mm; The thickness of inorganic fireproof board is 5mm which meets the standard of GB8624 A Grade Noninflammability; This compound material spray inside of Fire-Resistant Cable Tray, efficient heat insulation effect, protect cable from the damage of high temperature leaded from metal shell.
Surface Treatment
Spray Extra fire retardant coating on Electro galvanizing surface of cable tray. When meet with fire, coating would inflate on the surface and form dense carbide heat insulation, then close all cable tray gaps in order to avoid flame and high temperature gas being into cable tray. Inflation multiple is 40 times more than coating thickness.
Welding Technology
A. Common Welding B. CO2 Gas Shielded Arc Welding--- Strong Rust-proof and Weld Hypoxic weld joint
