Description
Advantages
Corrosion Resistant
Resistant to most chemicals, PVC is typically not affected by corrosive soils.And the conduit can be buried in concrete.
Non-conductive
Good insulation, able to resist AC2000V voltage and insulation resistance more than 1×10 Ω.
Self-Extinguishing
Properties make PVC fire resistant.
Impact Resistant
Tough, durable, with high tensile strength, yet easy to install and can be bent by spring under normal temperature.
Attracting appearance
Even color, good appearance, suitable for indoor installation.
