Insulating cable ladders 67

Insulating cable ladders 67 halogen free

Advantages
of the insulating material

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.

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.

Unalterable
against 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:

In the course of time.
After cutting, drilling and manual processing the material in the worksite

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.

Good performance outdoors
and with exposure to UV rays

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.

Easy, quick and safe
installation

Complete system of elements of form to facilitate the installation of the cable ladder on site
Kit type system that simplifies the assembly of the cable ladder.
The cutting, drilling and handling of insulating material does not produce burrs, sparks or irritating dust.
No welding is needed for mounting.
The mounting time is reduced and the durability of the tools is increased.
