Underground Tunnel Slotted Cable Tray Rail Transit Cable Support System | Heavy Gauge Perforated Slot Tray for Underground Cable Management
Product Overview
This underground tunnel slotted cable tray handles cabling in metros, road tunnels and utility shafts where long runs and fire safety matter. The folded metal sheet body is finished to resist heat and moisture, so the slotted cable tray keeps its structural toughness through years of vibration and daily service.
As a rugged cable support tray and slotted cable trunking, it carries power, lighting and communication cables along tunnel walls and ceilings, from small signal runs to multiple large cross section power cables. Perforated slots let heat and smoke move away, and customized logo printing helps tag long tunnel routes.
Features
Underground Tunnel Support Strong sections span long tunnel intervals between brackets. Stable support keeps heavy power and lighting cables level throughout the whole route.
Perforated Open Slot Base Punched openings allow airflow and smoke passage. They also give flexible fixing points for ties, clamps and cable cleats inside confined spaces.
Fire Retardant Galvanized Body Galvanized steel limits flame spread and resists heat. The body keeps its shape so circuits stay supported during and after a tunnel fire event.
Rugged Locking Joints Joint plates and bolts lock sections against vibration from passing traffic. Alignment stays true across very long tunnel installations.
