Factory direct supply of tunnel-specific aluminum core wires. High-voltage power cable YJLV22 with 3*50 aluminum wires. Abundant in stock. Starting from 10 meters.

The power supply for tunnels is dedicated, and the aluminum wire is abundant for greater peace of mind! The manufacturer directly supplies tunnel-specific aluminum-core high-voltage power cables – YJLV22 3×50, with sufficient aluminum wire filling and meeting the wire diameter standards. The national quality standards are strictly controlled. It is specially designed for the complex laying environment of tunnels, with ample stock and ready for immediate installation without any middleman markup. It is the high-performance and cost-effective preferred choice for tunnel engineering procurement and batch stock preparation!
✅ Direct supply from the manufacturer, ensuring controllable source quality! The factory directly supplies from the source, skipping all intermediate distribution links, completely eliminating the difference between middlemen, and offering discounted rates for bulk purchases. The entire production process is strictly controlled, from aluminum wire selection to product testing, with each step being rigorously inspected to ensure that the products meet the power supply standards for tunnels, making the procurement process more convenient and the use more reassuring.

✅ Special adaptation for tunnels, meeting complex scenarios! Specifically designed for tunnel laying scenarios, it is suitable for the special environment inside tunnels, which is humid, dark, narrow in space, and prone to mechanical impact. It has excellent wear resistance, corrosion resistance, and moisture-proof properties, and can withstand various external forces during tunnel construction and long-term use, eliminating potential safety hazards such as leakage and short circuits, ensuring stable and uninterrupted high-voltage power supply in the tunnel.
✅ YJLV22 3×50 model, specially designed for high voltage use! YJLV22 is an aluminum core cross-linked polyethylene insulated, steel tape armored, polyvinyl chloride sheathed high-voltage power cable. The model meaning is clear: YJ = cross-linked polyethylene insulation, L = aluminum core conductor, V = polyvinyl chloride sheath, 22 = steel tape armor + polyvinyl chloride outer sheath. The rated voltage is compatible with high-voltage systems ranging from 0.6/1kV to 8.7/15kV. It has a 3-core 50 square specification, perfectly meeting the requirements of high-voltage transmission and distribution in tunnels, with low power transmission loss and strong carrying capacity.
✅ Abundant aluminum wires, with excellent quality and durability! The core aluminum core is made of high-purity aluminum wires, filled fully without any gaps, with uniform wire diameter, processed through precise twisting technology. It has excellent electrical conductivity, low resistance, and low heat generation. At 20℃, the direct current resistance of the conductor strictly complies with national standards. The aluminum wires have great toughness, are resistant to oxidation and corrosion, and can quickly form an oxide film in a humid tunnel environment, extending the service life and reducing the weight of the cable, making it easier to be laid in narrow tunnel spaces.
✅ Steel tape armor + cross-linked insulation, upgraded dual protection! Cross-linked polyethylene (XLPE) insulation material, with outstanding insulation performance, heat resistance, and aging resistance, it can effectively prevent high-voltage leakage risks; the outer layer is double-layer galvanized steel tape armor, with high tensile strength and strong compressive resistance, which can effectively resist mechanical impacts in the tunnel, rock friction, and rat and insect bites, providing comprehensive protection for the cable from damage, suitable for direct burial in tunnels, cable trench laying and other methods.
✅ There is an ample supply of goods, and they can be dispatched immediately without affecting the work schedule! The intelligent warehouse has sufficient inventory, and there is no need to wait for production. Orders can be shipped directly after placing them, promptly meeting the progress requirements of tunnel engineering construction and avoiding delays in the project due to shortages. It supports small batch purchases and large batch wholesale, and has a professional team to handle orders, ensuring efficient shipping and timely restocking. It can provide relevant test reports and qualification certificates, and offers a one-stop solution to meet the procurement needs of tunnel engineering.
