Medium Voltage Cable NFA2XSY-T

MVTIC Cable refers to medium voltage twisted insulated cable. NFA2XSY-T type cable is a medium voltage cable with superior performance in electrical properties, mechanical strength and environmental adaptability. Its internal conductors are filled with a water-sealing barrier, which prevents water penetration during storage and installation and enhances the waterproof performance of the cable. NFA2XSY-T cables are rated for 12/20 kV and up to 24 kV system voltage, in accordance with standards such as SPLN 43-5 / IEC 60502-2. Depending on the requirements of the electrical project, the cables can have oil resistance, UV resistance,  and flame retardant.

NFA2XSY-T Application

It is mainly used in overhead lines for medium voltage power transmission, especially in areas where higher voltage carrying capacity is required and where the terrain is complicated or underground laying is not suitable.

NFA2XSY-T  Construction

• Conductor: Aluminium (Compact Circular Stranded). Internal gaps in the three conductors are filled with a waterproofing compound.
• Conductor shield: Extruded Semi-conductive Compound. Minimum thickness 0.5 mm. The maximum volume resistivity is specified as 5000 ohm-cm at 20°C and 25000 ohm-cm at 90°C.
• Insulation: Extruded Cross-linked Polyethylene (XLPE). It offers excellent electrical insulation, high temperature resistance and chemical stability.
• Insulation Shield: Extruded semi-conducting compound. Minimum thickness is 0.5 mm with a maximum volume resistivity of 5000 ohm-cm at 20°C and 25000 ohm-cm at 90°C.
• Metal Shield: Copper tape screen. Its thicknesses between 0.1 mm and 0.3 mm.
• Sheath: Extruded PVC 90°C grade. It provides physical protection against environmental factors such as ultraviolet (UV) light and mechanical damage.
• Messenger wire: Stranded Steel Wire, PVC 90°C Covered. It supports the weight of the cable during overhead laying and makes sure that it hangs stably.
