WKTD-HF-FR RESEALABLE CORRUGATED CONDUIT FOR ELECTRICAL INSTALLATION
Mechanical strength: 500N
Impact resistance: 1,0 kg/100mm
Temperature range (application, installation):
from -25°C to +110°C
Flexibility: pliable
Flammability: self-extinguishing HB (UL94)
Material: halogen free special plastic
Application:
Resealable corrugated conduit consists of two slit pipes that perfectly match together after closing. Specially designed construction enables to opened it and closed it many times. Application of pipe provides easy access to the cables and wires, which allows modification of an existing installation and removal of defects. Particularly recommended in the engineering, machinery and telecommunications industry. Conduit is characterized by high flexibility and strength to mechanical loads.
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.
