Description

　　Product Introduction

Using polyvinyl chloride resin (PVC) as the main raw material, necessary additives are added, and it is formed through extrusion processing; mainly used as electrical and communication cable conduits. It is classified into high-strength heavy-duty, general medium, and general light types based on mechanical properties.

　　Product Features

1. Good impact resistance; during the concrete pouring process, normal compressive impacts will not cause rupture, and it can be concealed within the concrete.

2. Good insulation; under flooding conditions, the conduit will not break down under 2500V 50Hz sine wave voltage for 15 minutes, with high resistance to current breakdown voltage and no live danger.

3. Good flame retardant self-extinguishing properties; high oxygen index, self-extinguishing upon removal from fire.

4. Excellent heat resistance; does not soften under condensation heat during construction.

5. Good compressive strength; high-strength heavy-duty conduits can withstand a pressure of 1250N, suitable for both surface mounting and concealed installation in concrete without damage from pressure.

6. Excellent moisture-proof and acid-base resistance; will not rust due to moisture, resistant to acid, alkali, and oil.

7. Pest and rodent resistant; due to the use of special additives, it does not emit odors that attract pests and rodents, preventing damage from gnawing; installation is convenient and quick by inserting corresponding special springs into the conduit, which can be bent to the desired angle at room temperature manually. With special adhesives, the conduits can be quickly and conveniently connected to form the required shapes for construction.

　　Application Fields

Mainly used for indoor and outdoor electrical and communication cable sheaths, building wiring layout, power line layout and protection in fire protection areas of general industrial plants and areas with acid-base corrosion.
