Higher safety for the installation

Insulating material: increased protection for people and cables

Provides additional insulation for people and cables, which remains unaltered in the course of time.

Insulating material:

Good resistance to 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.


Outdoor behaviour


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.

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).

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).

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.

* BS EN 61537 is the UK implementation of EN 61537 and IEC 61537.

* BS EN 50085-1 is the UK implementation of EN 50085-1.

Designed to work at 100% cable capacity

Safe working load test Type I acc./IEC 61537*

• Longitudinal deflection <1% and transverse deflection <5%.

• Safety coefficient 1.7.

Allows placing the junctions at any point between two brackets, assuring the safe admissible load.


Type I full load

Higher safety for the installation.

Simpler calculation process

in the design of the cable tray, execution and control of the installation. Load resistance

in future extensions of the installation.


Unex has designed a cable tray which is able to:

• Support the load of all the cables that may fit in the tray, considering the filling ratio.


Safe working load (SWL) in (kg/m) or (N) acc/ IEC 61537*

For cable trays of width ≥ 300 mm the use of a base union is necessary to comply with the requirements of full load transverse deflection defined by international Cable trays Standard IEC 61537.


A packaging designed to protect the product’s characteristics during transport
and storage, until the moment of final use.
