RKSG (-P) SELF-EXTINGUISHING CORRUGATED CONDUIT FOR ELECTRICAL INSTALLATION
Mechanical strength: 750N (medium) 3
Impact resistance: 2,0 kg/100mm (medium) 3
Temperature range (application, installation):
from -25°C to +60°C 4 1
Flexibility: pliable 2
Flammability: self-extinguishing
Material: lead-free, polyvinyl chloride (PVC-mod.)
EU Designation (EN 61386-1): 33412
Application:
Conduit designed for cable protection in building and industrial applications. Recommended for sunk wiring systems, external installations and places with an increased risk of fire hazard (wooden constructions, lofts, garrets, etc.). The RKSG type commonly used in vibrated concrete. It ensures high strength and resistance to mechanical factors. In spite of good strength properties it features high flexibility. Smooth inner profile enables easy cable installation in long sections. Conduit is available in versions:
– standard (RKSG)
– with draw wire to enable cables to be pulled through (RKSG-P).
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.
