PVC-U building insulation electrical conduit is a rigid polyvinyl chloride pipe of various specifications and models, made from PVC resin as the main raw material, with the addition of various stabilizers, anti-aging agents, impact-resistant agents and other additives, through extrusion processing. It features excellent safety and insulation, is lightweight, flexible, and easy and quick to install, meeting international standards. It can quickly extinguish spontaneously combustible flames, preventing the spread of fire. It can also withstand high voltage, avoiding the risk of electric shock. Widely used in building plastic electrical conduits and flame-retardant plastic electrical trunking, it is the ideal conduit material for protecting electrical circuits and has been recognized by millions of customers.
Product Introduction:
I. Implementation Standard: JG/T3050-1998 Insulating Electrical Conduit and Fittings for Building Use
II. Product Specifications: Divided into three types: Light-duty – 205, Medium-duty – 305, and Heavy-duty – 405.
1. Light-duty – 205: Outer diameter ￠16mm-￠50mm
2. Medium-duty – 305: Outer diameter ￠16mm-￠50mm
3. Heavy-duty – 405: Outer diameter ￠16mm-￠50mm
Product Advantages:
◆ Corrosion and Insect Resistance: Electrical conduits are moisture-proof and resistant to acids and alkalis, preventing rust. They are bonded with PVC adhesive, making them waterproof and moisture-proof. Special additives ensure they are odorless and prevent damage from insects and rodents.
◆ Bending and Easy Wiring: At room temperature, they are not easily broken when bent. Using a pipe bending spring, the conduit can be manually bent to the required angle, quickly and easily connecting the conduit into the desired construction shape.
◆ Excellent Flame Retardancy and Enhanced Safety: Electrical conduits are self-extinguishing (automatically extinguishing within 30 seconds of being removed from a flame), preventing flame spread along the conduit! The fire resistance rating meets the superior V-0 flame retardant standard.
◆ Thickened Wall, High Pressure Resistance: With a wall thickness of 1.3mm or more, electrical conduits can withstand pressure exceeding 750N, allowing for surface installation or laying within concrete without damage from pressure.
◆ High insulation and not easy to age: The electrical conduit is transparent in color and made of the latest materials. It is not easy to age and effectively protects the wires. It has good insulation and will not break down at AC2000 volts and 50Hz when immersed in water.

Application Areas:
PVC flame-retardant electrical conduit is widely used in concrete structures in building construction: as conduit for electrical wires (concealed conduit) between floors or inside walls, as well as as general wiring conduit (exposed conduit) and conduit for telecommunications, network cabling, etc. PVC electrical conduit allows for the insertion and replacement of wires or cables.
