MEDIUM VOLTAGE XLPE CABLE APPLICATION
XLPE insulated cable is used as transmission and distribution lines because of its excellent electrical and physical properties. This kind of cable has the advantages of simplicity in construction, lightness in weight, convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with no limitation of level difference along the route.
MEDIUM VOLTAGE XLPE CABLE CHARACTERISTICS
1. Voltages: 15 kV
2. The ambient temperature for installation: ≥0℃
3. Maximum conductor temperature in normal operation:≤90℃
4. Max operating temperature of con. When cable short-circuited (5s maximum duration): 250℃
5. Minimum Bending Radius
Single core – Fixed: 15 x overall diameter
3 core – Fixed: 12 x overall diameter
(Single core 12 x overall diameter and 3 core 10 x overall diameter where bands are positioned adjacent to joint or terminations provided that the bending is carefully controlled by the use of a former)
