NA2XBY/YJLV22 MV Aluminum Power Cable

Release time:2021-05-15

Aluminum Core XLPE Insulated Steel Tape Armored PVC Sheathed Power Cable

Product Description:
A cable is a conductor covered with an insulating layer, a protective layer, a shielding layer, etc., and is used to transmit power, signal current, or signal voltage. Compared with low-voltage overhead lines and low-voltage overhead insulated wires, low-voltage cable lines are more expensive and difficult to lay and maintain. However, due to reliable operation, no poles, no land occupation, inconspicuousness, and less external influence. Widely used in low-voltage distribution Electric system.

NA2XBY cables are laid indoors, in channels and pipelines, and can also be buried in loose soil together with insulated PVC sheathed power cables, and cannot withstand external forces. When the NA2XBY cable is laid underground, it can withstand external mechanical forces, but cannot withstand large tensile forces.

Conductor: high-purity oxygen-free aluminum core.
· Anti-aging, high conductivity, low current loss, strong load capacity, stable voltage, no heating, low resistance.
Sheath: PVC sheath
· The outer sheath is made of virgin materials, refuses to recycle waste, sun protection is not aging, waterproof, moisture-proof, low-temperature anti-freeze, high-temperature resistance to fire without burning.
Insulation: cross-linked polyethylene
· Uniform insulation thickness to ensure small wire eccentricity and improve resistance to current breakdown
Armored: steel tape armored
· Steel tape armor is safer and more reliable, suitable for underground burial, compression and extrusion, firm and durable.

Use characteristics:
Executive standard: GB/T12706-2008 standard production.
The rated power frequency voltage U0/U is 0.6/1KV, 8.7/10kV, and 18/30kV.
Maximum allowable working temperature of cable conductor: 90℃.
When short-circuit (the longest time is not more than 5s), the maximum temperature of the cable conductor does not exceed 250°C.
Cable bending diameter: the three-core cable is not less than 15 times the outer diameter of the cable; the single-core cable is not less than 20 times the outer diameter of the cable.

IEC 60228 conductor
IEC 60502-1 Extruded insulated power cables and accessories with rated voltages of 1kV (Um=1.2kV) to 30kV (Um=36kV)-Part 1: Rated voltages of 1kV (Um=1.2kV) and 3kV (Um= 3.6) Cable kV)
