Our industrial wiring ducts are built for organized, efficient cable routing, incorporating intentional structural details that simplify installation, servicing, and future panel modifications.

• Slotted Sidewall Design: Enables efficient routing of wires and cables directly from the duct to connected components, resulting in cleaner, more precise panel layouts.

• Integrated Bottom Mounting Holes: Simplifies installation inside industrial control panels and electrical enclosures, connecting easily to standard DIN rails.

• Toolless Finger Removal: The specialized finger design allows manual removal of sidewall sections without risk of injury, making routing modifications and upgrades smooth and simple.

• Removable Base Walls: Score lines allow easy removal of the wall section below the slots, providing additional internal routing space whenever increased cable capacity is required.

• Non-Slip Duct Covers: Features a specialized non-slip internal grip to keep covers locked securely in place, even in high-vibration or vertical mounting applications.

These wiring duct solutions are manufactured at a 2,500 m² facility in Limbiate, Italy, by a company founded in 1962. With over 60 years of experience, more than 3,000 product codes, and distribution to over 70 countries worldwide, this manufacturer is built on deep industry knowledge and a genuine commitment to quality, safety, and efficiency.

Their product range spans cable management systems, electrical insulation, and wire protection, all developed through ongoing research, testing, and collaboration with industry professionals. The company continuously invests in new manufacturing technologies, testing equipment, and product development to meet evolving industrial needs and exceed international standards.

Whether you're building a new panel or maintaining an existing one, the right wiring duct makes the whole job cleaner, faster, and safer.

Every single product series undergoes exhaustive in-house testing and production quality control protocols prior to distribution. Our component validation process guarantees structural and electrical stability under demanding operating conditions through:

• •Low & Room Temperature Shock Testing: Ensures impact resistance and structural integrity across varying climate exposures.

• •850°C Glow Wire Testing (GWT): Verifies severe heat resistance and material safety limits under extreme thermal loads.

• •Flame Propagation Resistance Testing: Assures self-extinguishing material performance to mitigate fire hazards within enclosures.

• •Insulation Resistance Testing (>100 MΩ): Confirms high-voltage dielectric security to protect sensitive control circuitry.

• •Accelerated Age Testing: Simulates years of continuous operation to forecast long-term material stability.

• •Mechanical Stress Testing: Evaluates the continuous resilience of sidewalls, lids, and fingers during manual removal and modifications.

•  

This exhaustive testing matrix ensures that our distributed routing ducts maintain optimal structural strength, deliver elite electrical insulation, and perform with total reliability throughout the lifespan of your industrial electrical installations.

For specialized industrial installations requiring advanced fire-safety protocols, TCH supplies high-performance, halogen-free wiring duct solutions engineered for railway, mass transit, and heavy public infrastructure applications.

Manufactured from specialized PC/ABS and Noryl thermoplastic compounds, these lines are engineered to minimize toxic gas, corrosive smoke, and hazardous emissions in the event of a thermal emergency. This makes them the definitive choice for rolling stock, locomotives, subway tunnels, and electrical installations inside densely occupied public environments.

Our specialized halogen-free product lines are fully certified and comply with rigorous international safety benchmarks, including:

• • CEI EN 50085-2-3: Standard for slotted cable trunking systems intended for installation in electrical enclosures
• • UNI-EN 45545-2:2015: Railway standard for fire safety and material behavior on transit vehicles
• • EN ISO 4589-2: Determination of burning behavior by oxygen index testing
• • NFX 70-100: Analysis of toxicity index and gaseous evaluation during material combustion
