PVC Cable Casing Ducts

PVC power conduit

The scientific name of PVC pipe material is polyvinyl chloride, which is a thermoplastic resin material. It has very good mechanical properties and a tensile strength of about 60MPa. Adding some auxiliary agents during the pipe making process will make PVC pipes flame retardant and resistant. Acid and alkali, wear-resistant insulation properties,

Different application fields require PVC pipes to have different functions, so the application of PVC wiring pipes will also be different. The following editor will show you how to use PVC wiring pipes in different places.

1. For wire conduits concealed in walls, buried in underground non-combustible bodies, and wire conduits used in rural buildings and other ordinary residential buildings, they must be made of wire conduits that meet the standards of the Ministry of Construction JG3050-199 [1] 8 “Insulation Electrician for Buildings” Casings and Accessories are PVC threading pipes that have certain flame retardant properties and meet the physical and mechanical performance requirements. According to the details and local conditions.

2. When carrying out pipe protection for wires in ceilings and floors in places with high fire risks, such as hotels, restaurants, shopping malls (large supermarkets), libraries, singing and dancing entertainment venues and other public gathering places, because of the There are many flammable and flammable materials, so flame-retardant PVC wiring pipes with higher combustion performance levels should be selected.

3. It is mandatory to use flame-retardant PVC threading pipes that meet the standards of the Ministry of Public Security for fire distribution lines and automatic fire alarm system electrical lines.

4. For the renovation of exposed electrical lines in cultural relics and ancient buildings, indoor decoration and secondary decoration of houses, as well as the renovation of old and old buildings that need to use exposed lines (hidden in suspended ceilings and floors), they must use combustion performance B1 or above. Flame retardant PVC conduit.

Wires buried in the wall must be threaded through conduits. Generally, there are two options: metal threading conduits and PVC threading conduits: metal threading conduits are more expensive, but their anti-interference performance is stronger than PVC threading conduits, they are not afraid of fire, and they will also be more protective of wires in the future. In PVC conduit. PVC conduit is affordable, easier to turn than metal conduit, and has good insulation properties.
