Easy to bend and convenient for construction: Lightweight, bendable at any angle without heating. 5. Simple connection: Uses adhesive to connect conduit and fittings.
Flame-retardant Insulating PVC Electrical Conduit
Product Introduction:
PVC electrical conduit is a kind of conduit supported by flame-retardant material. It acts on the outside of electric wires and can effectively avoid the occurrence of electric leakage caused by wire faults, ensuring the safety of household electricity consumption. At the same time, PVC electrical conduit also has very good corrosion resistance and compressive strength.
