WKTD-PP – 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: flammable
Material: polypropylene mod. (PP-mod)
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:
Flammable material, medium tensile strength, medium rigidity, good 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.
