Introducing our Trough Type Fireproof Cable Tray, engineered specifically for fire safety in critical applications. PROtrough is an innovative, lightweight, fire retardant cable trough system that offers a modern alternative to traditional concrete trough systems for rail, light rail and power markets. PROtrough has been designed to be lightweight and comply with major rail fire retardancy specifications for. Strong Anti-Interference Capability: The enclosed structure shields against electromagnetic interference (EMI), making it suitable for low-voltage signal cables. Flame Retardant & Fire Resistant: During a fire, the coating expands to form a thermal barrier, preventing flame spread and protecting. Cablofil steel trough trays provide the strength and security required when then need to limit cable access is of primary importance. Cablofil steel trough trays. A trough cable tray is a type of cable management system designed to protect and support electrical, communication, or data cables in commercial, industrial, or data center installations. Its “trough” design—often featuring a solid or partially enclosed bottom—provides an effective barrier against.
