10kv-35kv
Standard and range of application
The products, Cu core or Al core XLPE aerial insulated electric power cables, may be used the fields where the AC rated voltage Uo/U is 10(12)kV, 35(42)kV individually.
Using features
Max. Permitted working temperature of the cables conductor (cable having supporting structure) is:
1. XLPE insulated electric power cable 90 o C
2. HDPE insulated electric power cable 75 o C
When short circuit (the Max. Lasting time is not over 5 seconds), the Max. Temperature if the cable:
1. XLPE insulated 250 o C
2. HDPE insulated 150 o C
When lying, the temperature should not be low than -20 o C, the permitted bending radius should not be less than the diameter of cylinder that had been used for the bend testing.
1kv or less
Standard and application scope
referring and adapting the stan�ards of IEC502 and IEC227. And it is suitable for aerial insulated cable with AC rated voltage 0.6/1 kV or less.
Using features
The permitted working temperature if cable, conductor in a long time is:
1. For PVC and PE insulated should not be over 70 o C
2. For XLPE insulated should not be over 90 o C;
The laying temperature of the cable should not be below -20 o C. The permitted bent radius of the cable:
1. If the outside diameter if the cable (D) is less than 25mm. It should not be less then 4(D);
2. If the outside diameter if the cable (D) is 25mm or more, it should not be less than 6(D)
