A, the product standard
This product according to GB 12527, GB 14049 for the production.
Second, the applicable scope
This cable has resistance to climate, wear-resisting, high mechanical strength, the line loss small features. Widely used in various areas network reconstruction, can dramatically improve the safety of power grid reliability, rated voltage 35 kV power network.
Three, use properties
PE, PVC insulated cables long-term temperature not allowed to work more than 70 ℃, crosslinked polyethylene insulated cables long-term temperature not allowed to work more than 90 ℃. When a short circuit (5 seconds) polyethylene insulated cables allowed to work temperature not over 130 ℃, PVC insulated cables are not more than 160 ℃, crosslinked polyethylene insulated cables, no more than 250 ℃. Install the ambient temperature of not less than 20 ℃-
The rated voltage of the 0.6/1 kV cable diameter as less than 25 mm, allows the smallest bending radius is four times the outer diameter of cable; Such as cable diameter is equal to or greater than 25 mm, allows the smallest bending radius is six times the outer diameter of cable. More than 10 kV rated voltage 35 kV the following many core cable, smallest bending radius should not less than 15 times the outer diameter of cable diameter and conductor, single core cable should be no less than 20 times the outer diameter of cable diameter and conductor.
