RGSG – SELF-EXTINGUISHING RIGID PIPE FOR ELECTRICAL INSTALLATION
Mechanical strength: 750N (medium) 3
Impact resistance: 2,0 kg/100mm (medium) 3
Temperature range (application, installation):
from -25°C to +90°C 4 2
Flexibility: pliable 2
Flammability: self-extinguishing 1
Material: polyethylene mod. (PE mod.)
EU Designation (EN 61386-1): 33422_2
Application:
Pipe designed for cable protection in building and industrial applications. Ideal for use in locations where there is an increased risk of fire hazard (RGSG). It can be used in sunk wiring systems, internal installations including cavity walls. Recommended also for teletechnical cable installation.
Used material ensures high mechanical strength and resistance to temperature. Pipes can be used in places where there is a risk of mechanical damage and a moment of an increased temperature (vibrated and steamed concrete). The pipes are available in coils which facilitates transportation, storage and limit the necessity of using connectors.
Characteristics of material:
Self-extinguishing/flame retardant material, medium tensile strength, medium rigidity, high impact strength, high thermal resistance, resistant to most of chemical compounds, good dielectric properties within a wide temperature range even in a wet environment, high water absorption resistance, inconsiderable deformability.
