Cable Types:
N2xsery: This is a type of power cable that conforms to the European standard HD 620. It features copper conductors, XLPE (cross-linked polyethylene) insulation, and an armor layer. The "e" in N2xsery indicates that it has improved resistance to fire propagation.
N2xsey: Similar to N2xsery, N2xsey is another type of power cable that meets the European standard HD 620. It also has copper conductors and XLPE insulation. However, it does not have the enhanced fire propagation resistance of N2xsery.
Voltage Ratings:
The cable is available in different voltage ratings, including 11kV, 22kV, and 33kV. These ratings indicate the maximum voltage at which the cable can safely operate.
XLPE (cross-linked polyethylene) insulated cable refers to an electrical cable that has conductors insulated with XLPE material. XLPE is a thermosetting polymer known for its excellent electrical properties, making it a popular choice for various applications in the power transmission and distribution industry.
Insulation Material: XLPE is a type of polyethylene that is chemically cross-linked. This cross-linking process improves the thermal and mechanical properties of the insulation, making it more robust and durable compared to non-cross-linked materials.
Electrical Performance: XLPE insulation offers high dielectric strength, low dielectric losses, and excellent insulation resistance. This allows for efficient power transmission while minimizing energy losses.
Thermal Properties: XLPE insulation can withstand higher operating temperatures than traditional PVC (polyvinyl chloride) insulation. This makes XLPE cables suitable for applications that require higher temperature ratings.
Environmental Resistance: XLPE insulation provides good resistance to moisture, chemicals, and environmental stresses, such as UV radiation. This makes XLPE cables suitable for indoor and outdoor installations.
