Ask the manufacturer for a sample. Why not download an electronic version?

When multiple wires are passed through a tube, the total cross-sectional area of the wires (including the insulation) should not exceed 40% of the internal area of the tube. The inner diameter of the tube should be 1.4 to 1.5 times the diameter of the wire bundle. The outer diameter of the ZR-YJV-1KV-4X50+1X25 cable is 31 mm; therefore, a water-gas steel pipe (SC) with a diameter of DN50 or larger should be used. If the length exceeds 50m, add an elbow and increase the pipe diameter by one size.
