RL SELF-EXTINGUISHING RIGID PIPE FOR ELECTRICAL INSTALLATION
Mechanical strength: 320N (light) 2
Impact resistance: 1,0 kg/100mm (light) 2
Temperature range (application, installation):
from -25°C to +60°C 4 1
Flexibility: rigid 1
Flammability: self-extinguishing
Material: lead-free, polyvinyl chloride (PVC-mod.)
EU Designation (EN 61386-1): 22411
Application:
Rigid pipe is used for distribution and protection of cables in building and industrial electrical installations. Recommended for open surface as well as for under concrete installation. Pipe has ideally smooth surface.
Standard length of the rigid electro-installation pipes is 3 m.
Characteristics of material:
Lead free, self-extinguishing/flame retardant, high mechanical strength coefficient and excellent percussion strength properties, little unit elongation, medium-elastic when tensioned, immune to pressures and most of chemical compounds, very good dielectric properties.
