 3Standard for production

 The standard for producing 35kv XLPE insulated power cable with for subway is GB/T 12706-2008 and enterprise standard.

1)About the conductor:

For the hard cable, the conductor shall meet the requirement of GB/T 3956-2008 over the second type annealed bare copper conductor.

For the flexible cable, the conductor shall meet the requirement of GB/T 3956-2008 over the sixth or similar metallic or non-metallic layer annealed copper conductor, usually metallic layer is tin.

2)The Max. permissible operating temperature of the cable is 90°C.

3)The water permeability test for the cable meets the requirement of GB/T 12706-2008.

4)the cable passed the electro-osmosis proof test , without breakdown under 240h, 1800v DC voltage

5)The low smoke performance when burning meet the requirement of GB/T 17651, it is that the Min. light transmittance of the density of smoke when burning is not less than 60%.

6)The PH value of the emergent gas when burning is not less than 3%, and the electric conductivity is not more than 10µs/mm.
