Range of cable trays in insulating material, with perforated or non perforated base, which provides greater electrical safety for people and for the installation.
No possibility of short circuit due to contact of damaged phases with the cable tray.
Maintenance-free
Does not require maintenance for earthing nor corrosion.
Benefits of the insulating material
Insulating material: maximum electrical safety
Electrical insulation is maintained over time.
Increased protection for people and cables.
Cost saving due to the ease of the installation, project management and maintenance.
High impact absorption
Impact test acc./IEC 61537 at the minimum declared temperature.
Unex designs its cable trays to avoid impact damage at their lowest declared temperature (-20ºC).
Impact resistance
Minimum temperature
20J*
-20ºC
*Except sizes 60x75: (5 J) and 60x100: (10 J).
Impact test acc./EN 50085-1.
Unex insulating cable tray with cover, by complying with the European Standard EN 50085-2-1, is considered a protecting enclosure (trunking).
Impact test for trunkings: IK10 (with cover fixing).
Unalterable against corrosion
The raw material assures excellent behaviour in front of corrosion; this feature is inherent, it is not achieved by applying a coating to the final product.
Therefore, the corrosion protection remains unchanged:
In the course of time.
After cutting and manual processing the material in the worksite.
According to Cable tray standard IEC 61537:2007 resistance to humid and saline corrosion, Unex insulating materials "are inherently resistant to corrosion and do not require testing."
Good performance outdoors and with exposure to UV rays
Unex insulating cable trays are designed to assure a good protection against the UV rays:
Own raw material formulation, suitable for UV rays exposure.
Unex insulating cable trays are endorsed by 40 years’ experience in outdoor installations.
Unex insulating cable trays are designed to absorb linear expansion. The “d” distance between two lengths varies depending on the difference between the maximum temperature and the installation temperature.

Reaction to fire
Unex cable tray passes the flammability and flame-propagation tests included in IEC 61537 with the best classification required from organic materials.
Glow-wire test IEC 61537
Test measuring the material's flammability by overheating a conductor.
Non-flame propagating IEC 61537
Test measuring flame spread caused by electrical ignition sources.
Flammability test UL94: V0 (thickness of the material tested: 2.5 mm).
No heat propagation
As a result of the low thermal conductivity of insulating materials, no hot spots are generated away from the fire source.

Safe working load: Type I full load
Designed to work at 100% cable capacity
Increase in the overall safety of the installation. For safety Unex has designed the cable tray to:
Withstand the load of all the cables that fit according to the useful section of each size.
Withstand up to 70% more of this load without breakage.
Simplify the calculations in the design of the cable tray system, the execution and control of the installation.
According to IEC 61537
The IEC 61537 cable trays standard establishes three types of tests. Unex certifies the Type I test on all its insulating cable trays at full load:
In the installation process, the position of the junction with respect to the support (d) is not conditioned.
Design and site management is simplified.
Distance between supports at full load - Raw material U23X
Support distance at full load according to the longitudinal and transverse deflection:
T = 40 °C span 1.5 m.
T = 60 °C span 1 m.
Longitudinal deflection less than 1% and transverse deflection less than 5%.
