1、The electric cable is designed with 5 cores, of which 3 cores are composed of 49 copper wires, and 2 cores are composed of 48 copper wires, with good performance. 2、The conductor is made of high‑purity copper, which has good electrical conductivity and power transmission performance. 3、The insulating material is made of PVC, which can protect the wire from sunlight and chemicals. 4、5‑core power cables are used in 3‑phase 5‑wire transmission and distribution systems, and are installed in place at one time. 5、Since the neutral wire core is separated from the ground wire, the system runs more stable and safer to use. 1 x Electrical Wire Item Type: Electrical WireMaterial: Copper, PVCModel: RVV3 x 2.5 + 2 x 1.5Colour: BlackWire Length: Approx. 100meter / 328.1ftCable Specification: 5 cores (3 cores have a conductor cross section of 2.5mm², and 2 cores have a conductor cross section of 1.5mm²)Conductor Cross-Sectional Size: 3 x 2.5 + 2 x 1.5mm²Conductor Cores/Single Wire Diameter: 49/ 0.25 + 48/ 0.2mm (the number of 3 cores/wire diameter is 49/ 0.25mm, and the number of 2 cores/wire diameter is 48/ 0.2mm)Rated Voltage: AC300VMaximum Withstand Voltage: AC500VPurpose: Suitable for household appliances, small electric tools, instruments, meters, power lighting, etc. with rated voltage below AC300/500V.
