4‑Core 4x25mm² Pure Copper Low Voltage Power Cable IEC Standard for Building Wiring
Full range of products can be customized
Our 4×25mm² 4‑core low‑voltage copper power cable is rated at 0.6/1kV, available in non‑armored YJV and steel‑tape armored YJV22 versions. Constructed with high‑purity oxygen‑free copper conductors and XLPE insulation, it delivers stable current‑carrying capacity, low energy loss and excellent heat‑resistant performance up to 90 ℃ long‑term working temperature.
YJV type features flexible structure for indoor laying, cable trenches and conduit installation. YJV22 adds steel tape armour to resist mechanical impact, suitable for direct underground burial. Manufactured in accordance with IEC 60502‑1 standards, this cable is widely used for three‑phase four‑wire power distribution in factories, commercial buildings and municipal engineering projects. Custom cutting length is supported for wholesale and EPC project demands.
1.Adopts high‑purity oxygen‑free copper conductor, featuring outstanding electrical conductivity, minimal electrical resistance, low power loss and stable long‑distance power transmission performance. Uniform conductor structure ensures consistent current‑carrying capacity and avoids local overheating during continuous load operation.
2.High‑performance XLPE cross‑linked polyethylene insulation layer delivers excellent thermal resistance, high‑temperature tolerance, anti‑aging and dielectric properties. It can sustain long‑term working temperature up to 90℃ and effectively extend cable service life under continuous operation.
3.Heavy‑duty PVC outer sheath provides great wear resistance, moisture resistance, oil resistance and chemical corrosion resistance. It protects inner core from dust, humidity and mild chemical erosion in indoor and cable‑trench environments.
4.Optimized cable structural design brings moderate flexibility, convenient for transportation, handling and laying. Suitable for installation inside buildings, cable trenches, cable ducts without heavy external mechanical impact.
5.Wide range of cross‑section sizes available, covering small‑size building wiring to large‑size industrial main‑circuit power transmission. Support custom cutting length according to actual project demands, convenient for bulk project procurement.
