DN200 Hot-Dip Galvanized Steel Pipe for Cable Protection, with Inner and Outer Coating Hot-Dip Galvanized Steel Pipe

Cable protection conduits are steel-plastic composite pipes coated with polyethylene or modified epoxy resin powder on both the inside and outside. These composite conduits for cables offer excellent chemical stability, good mechanical properties, and high compressive strength, providing superior protection for cables. Different plastic coatings can meet usage requirements from -40℃ to 90℃ of external temperatures, making them suitable for high and low voltage cable installations. Pipe connections can be made in various ways, greatly facilitating on-site construction. The cable sheath conduits possess excellent comprehensive properties, effectively offering good protection and anti-aging effects for cables.
