RIL-HF-FR (-P) SELF-EXTINGUISHING CORRUGATED CONDUIT FOR ELECTRICAL INSTALLATION
Mechanical strength: 320N (light) 2
Impact resistance: 1,0 kg/100mm (light) 2
Temperature range (application, installation):
from -25°C to +110°C 4 3
Flexibility: pliable 2
Flammability: self-extinguishing HB (Ul94)
Material: special plastic
EU Designation (EN 61386-1): 22432
Application:
Corrugated conduit is used for distribution and protection of cables in building and industrial electrical installations. Recommended for places, with an increased risk of fire hazard (wooden constructions, lofts, garrets, etc.) and tightened security against toxic chemical compounds (halogen free). It ensures high strength and resistance to mechanical factors. Pipe has ideally smooth surface. In spite of good strength properities it features high flexibility. Smooth inner profile enables easy cable installation in long sections.
Characteristics of material:
Free from halogen (phosphorus and cadmium) self-extinguishing/flame retardant, high-bending and crack resistance, well balanced elongation and elasticity behaviour as well as high abrasion-resistance, high tensile strength, rigidity, high impact strength.
