The Difference Between PVC Conduit and Fiberglass Conduit

PVC conduit and fiberglass conduit are two different materials that are used to protect and route electrical wires. While both types of conduit serve the same purpose, there are some key differences between them.

材料

PVC conduit is made from a plastic material called polyvinyl chloride, while fiberglass conduit is made from a composite material consisting of glass fibers and resin.

Strength

Fiberglass conduit is generally stronger than PVC conduit and is more resistant to impact and crushing. This makes it a better choice for applications where the conduit may be exposed to physical damage.

耐腐蚀性

Fiberglass conduit is more resistant to corrosion than PVC conduit, which makes it a better choice for applications where the conduit may be exposed to chemicals or other corrosive substances.

耐热性

Fiberglass conduit has superior heat resistance compared to PVC conduit. PVC conduit can melt or burn through in high-temperature conditions, while fiberglass conduit can withstand much higher temperatures without breaking down.

重量

Fiberglass conduit is generally lighter in weight than PVC conduit, which can make it easier to install and may reduce the load on supporting structures.

Cost

Fiberglass conduit may be a more cost-effective option than PVC conduit in certain cases. While the cost of materials may not always be lower for fiberglass conduit, it can result in lower installation costs due to the reduced labor hours needed for installation.
