Railway infrastructure


• Electrical:

Dielectric strength: protection against the risk of electrocution through indirect contact.

• In front of fire:

Reduces the risk of electrical arcs and fire sources.

Own formulation of our raw materials, providing outstanding features with regards to standard ones.

• Reliability of the signal transmitted:

Avoids eddy currents and facilitates the control of the grounding system.

Cost reduction:

• Earthing not required:

No need for copper conductors.

No costs derived from connecting the conducting element to the grounding system or from periodical checking.

• No induced or leakage currents, avoiding premature corrosion which usually affects metallic channelling.

• Lower installation costs

Over 35 years experience in outdoor installations:

• Non-metallic material: resistant to corrosion caused by outdoor exposure or by saline, polluted

or chemically aggressive environments.

• Sturdy design, high impact resistance.

• Good performance outdoors and suitable for UV exposure, due to our own formulated raw materials.

Mounting and integration

• Complete system of accessories and supporting elements in grey RAL 7035:

Several mounting arrangements are possible.

Homogeneous colour of the trays, trunkings and fittings, perfectly fitting with other constructive elements.

• Can be painted.

Rolling stock

• Unex Slotted trunkings 88 in U43X (own-formulated raw material) have successfully passed tests of fire safety

according to EN 45545-2 (2013), meeting the requirements R22-R23 (both inside and outside railway vehicles)

for hazard levels HL1 to HL3.

• Safe installation assured by the trunking’s sturdiness.

• The cover is easy to mount and remove and does not fall or slide in any mounting position.

• Two possibilities to cut the trunking sidewall: either removing the finger or cutting until the base.

• Rounded fingers: no cutting tips or edges, avoiding damage to cables and personal injury, both during mounting

and transportation; not affected by vibrations.
