N2XS(FL)2Y
General information
Standard: TŞ AZ 2002283071.008 (IEC 60840) The Russian analogue: PvP2g These cables are used in water bodies where there is no moving water vehicles, and on the ground, without taking into account the degree of corrosiveness (in trenches or concrete channels), provided that there is protection against mechanical impact.
XLPE insulated high voltage cable with a copper conductor, a water-blocking semiconducting and aluminum polymer tape, and a sheath of polyethylene (PE)
Structure:
- The conductor is copper, multi-wire, round and compacted; corresponds to class 2 of IEC 60228
- The cross-section of a multi-wire compacted round conductor is 185÷800 mm2
- The cross-section of a multi-wire compacted round conductor, consisting of 5 sectors, is 1000÷1600 mm2
- The conductor screen is made of extruded semiconducting cross-linked polyethylene
3. Insulation is cross-linked polyethylene (2X)
4. Insulation screen is made of extruded semiconducting cross-linked polyethylene
5. The separation layer is made of semi-conductive water-blocking tape
6. The screen is of copper wires fastened with copper tape (S)
Minimum cross-section of screen for cables with a conductor cross-section of 185-800 mm2 - 35 mm2
Minimum cross-section of screen for cables with a conductor cross-section of 1000 mm2 and above is 50 mm2
The maximum cross-section of screen can be set based on the customer's require.
- The separation layer is made of semi-conductive water-blocking tape (FL)
8. Waterproofing tape is made of aluminum polymer tape
9. The outer protective sheath is made of polyethylene (2Y)
Specifications:
- Operating temperature of the conductor: +90 0C
- The maximum heating temperature of the cable conductors in case of emergency: +130 0C
- The maximum heating temperature of the cable conductors in case of emergency: +250 0С
- The duration of a short circuit (not more than): 5 seconds
- Cable laying temperature (not less than): -15 0С
- Ambient temperature: -60 / +50 0C
- Minimum bending radius of the cable: 15xD (D is outer diameter of the cable)
