It is equipped with rubber sheathing for protection, featuring excellent flame retardant performance, strong insulation, and high-purity copper core for efficient conduction. The quality is strictly controlled according to national standards, suitable for various high-voltage power transmission and distribution projects. Direct supply from the source, professional connection. It is a reliable choice for engineering procurement and batch stock preparation!
✅ Professional supply by the manufacturer, quality under full control! With years of deep research in the cable field, it possesses a professional production, research and development, and testing system, focusing on the supply of high-voltage copper core cables. It strictly controls every process from raw material selection to finished product manufacturing. The professional team connects the demand, can provide complete qualification certificates and test reports, ensuring that the products meet the engineering acceptance standards, making the procurement more worry-free and the use more reassuring.

✅ Enhanced flame retardant properties, ensuring more comprehensive safety protection! Utilizing flame-retardant rubber sleeves and flame-retardant insulating materials, it meets the national standard for flame retardancy. Once removed from an open flame, it can extinguish itself, effectively suppressing the spread of flames. During combustion, it has low smoke density and low toxicity, preventing secondary hazards during a fire and strengthening the safety barrier for high-voltage power transmission. It is suitable for high-voltage projects, public facilities, industrial plants and other scenarios with high requirements for fire safety.
✅ Rubber sleeve protection, suitable for complex environments! The special rubber sleeve has undergone special processing. It not only has excellent flame-retardant properties, but also has good insulation, wear resistance and weather resistance. It can effectively resist outdoor wind and rain, high temperatures, severe cold, ultraviolet rays and chemical corrosion. It does not age easily, does not crack easily, and has excellent flexibility, making it convenient for laying in complex engineering scenarios. It avoids damage to cables caused by pulling and friction.
✅ YJV22 3×240 model, specially designed for high-voltage copper cores! YJV22 is a high-voltage power cable with copper core, cross-linked polyethylene insulation, steel tape armor, and polyvinyl chloride sheath. The model meaning is clear: YJ = cross-linked polyethylene insulation, V = polyvinyl chloride sheath, 22 = steel tape armor + polyvinyl chloride outer sheath, without “L” marking it is a pure copper core conductor. The rated voltage is suitable for 6kV to 35kV high-voltage systems. 3-core 240 square specification, perfectly matching the requirements of high-voltage large-power power transmission and distribution, with stable power transmission, low loss, and strong carrying capacity.
✅ High-purity copper core, efficient and durable conduction! The core conductor is made of high-purity copper, with pure material and no impurities. It has excellent electrical conductivity, low resistance and low heat generation. At 20℃, the DC resistance of the core conductor strictly complies with national standards, providing sufficient current-carrying capacity. It is suitable for large industrial equipment power supply, main lines of substations, long-distance high-voltage power transmission and distribution in medium and large power scenarios. The copper core is highly resilient, and it is not prone to oxidation or core breakage during long-term use. It has a long service life, ensuring the stability of cable transmission from the core material.
✅ Steel tape armor, enhanced protection! The outer layer is made with a double-layer galvanized steel tape armor process, which is precise and has high tensile strength and strong compressive resistance. It can effectively resist external physical impacts, vehicle碾压， and rat or insect bites. Combined with rubber sleeves and cross-linked insulation， it forms a triple protection system， providing all-round protection for the cable from damage. It is suitable for various engineering laying environments such as direct burial， tunnels， cable trenches， and outdoor settings， and has extremely strong adaptability.
✅ Flexible procurement, professional coordination! Support small-batch purchasing, large-batch wholesale, direct supply from manufacturers without middlemen. Bulk purchases can enjoy discounts. Sufficient stock available, efficient delivery, timely restocking. A professional team provides full coordination for engineering procurement needs. Based on actual scenarios, it can offer selection suggestions and solve the pain points of high-voltage cable procurement in one step, helping the project progress efficiently.
