Insulating cable ladder for the support and conduction of electrical and communications cables in indoor and outdoor installations.
Protection against indirect contacts
No earthing required.
No equipotential bonding is needed.
Without transmission of dangerous currents.
Possible sources of fire are reduced
No possibility of short circuit due to contact of damaged phases with the cable ladder.
Maintenance-free
Does not require maintenance for earthing nor corrosion.
The raw material of the Insulating cable ladder 67 and accessories* in U23X has an excellent behaviour in front of corrosion, endorsed by more than 40 years of experience with the Insulating cable tray 66. This resistance is ensured by the raw material in itself; it is not achieved by applying a coating to the final product. Therefore, the corrosion protection remains unchanged:
The behaviour in chemical environments of Unex insulating materials is defined by DIN 8061 and ISO/TR 10358 standards depending on the chemical agent, concentration and temperature.
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."
*Some of the accessories are made in U48X halogen free material.
Raw material formulation suitable for UV rays exposure. More than 40 years´ experience in outdoor installations. Unex insulating cable ladders 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.
