✅ Analysis of YJV22 8.7/15KV Model: Professional high-voltage performance traceable! YJV22 is a copper core cross-linked polyethylene insulated, steel tape armored, polyvinyl chloride sheathed high-voltage power cable. The meaning of the model letters is clear: Y represents cross-linked polyethylene (XLPE) insulation, J represents power cable, V represents polyvinyl chloride sheath, and 22 represents steel tape armor + polyvinyl chloride outer sheath. It precisely fits the 8.7/15KV high-voltage system. It strictly follows national standards such as GB/T 12706.1-2008 and IEC 60502-1. Additionally, it complies with the requirements of GB/T 19666-2005 on flame retardant and fire-resistant cables, and the quality is traceable.
✅ 8.7/15KV high-voltage compatibility, with ample safety redundancy! The voltage marking of 8.7/15KV follows the golden ratio design of the three-phase AC system. Here, U₀ (the rated working frequency voltage between the conductors and the ground) is 8.7KV, U (the rated working frequency voltage between the conductors) is 15KV, and the maximum withstand voltage can reach 17.5KV. It can easily handle voltage fluctuations and lightning overvoltage, has strong shock resistance, can be downward compatible with the 10KV system, and has greater safety. The long-term working temperature of the cable can reach 90℃, and the short-term overload temperature is ≤130℃. The finished cable can withstand an AC 50HZ 21KV voltage test for 30 minutes without breakdown, has a large insulation resistance, eliminates the risks of high-voltage leakage and short circuits, and ensures stable and uninterrupted high-voltage power transmission.
✅ 3-core full specification coverage, suitable for various high-voltage scenarios! With a 3-core structure, it perfectly matches the three-phase power system, covering all specifications from 35 to 300 square meters (35, 50, 70, 95, 120, 150, 185, 240, 300 square meters). It can be flexibly selected according to the engineering load requirements: 35-70 square meters is suitable for small and medium-sized high-voltage distribution networks and branch lines in industrial areas; 95-150 square meters is suitable for municipal main roads distribution networks and main power lines of large residential areas; 185-300 square meters is suitable for power supply of large industrial equipment, transmission of substations, and long-distance high-voltage power transmission and distribution projects. It provides one-stop solutions for high-voltage wiring needs in multiple industries such as power, construction, metallurgy, petrochemicals, and transportation.
✅ Cross-linked insulation + steel tape armor, double protection for greater durability! Utilizing cross-linked polyethylene (XLPE) insulation material, after cross-linking treatment, it forms a network-like three-dimensional structure, with excellent heat resistance. Below 200℃, it will not decompose or carbonize. The insulation performance is outstanding, with a small tangent value of dielectric loss angle and less sensitivity to temperature. It also has strong resistance to acid and alkali as well as oil. The combustion products are environmentally friendly, meeting modern fire safety requirements. The outer layer uses 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， rat and insect bites. Combined with the polyvinyl chloride outer sheath， it forms a composite protection system. It is resistant to wear， aging， and corrosion， suitable for various complex laying environments such as direct burial， tunnels， cable trenches， and outdoor areas. The service life can reach over 40 years.
✅ Excellent core performance, convenient and efficient construction! The conductor adopts Class 2 stranded copper conductor, combined with semiconductive shielding layer and semiconductive insulation shielding. It has excellent conductivity, low resistance, low heat generation, and low power transmission loss. At 20℃, the DC resistance of the conductor strictly complies with national standards. For example, for a 300-square-meter conductor, the DC resistance ≤ 0.0754Ω/km. The overall flexibility of the cable is good. The multi-core bending radius is ≥ 20×D (D is the outer diameter of the cable), which is convenient for laying in complex and narrow spaces, significantly improving construction efficiency. At the same time, it can withstand large mechanical external forces and is suitable for various high-voltage engineering complex wiring environments.
✅ National standard certification, ensuring peace of mind in engineering procurement! Each roll of cable undergoes multiple rigorous inspections and has a complete test report. Partial discharge is ≤ 10 pC (at 1.73U₀), and it can withstand a lightning impulse of 95 kV (10 times for both positive and negative poles). All performance standards are met. It can be verified in real time on the official website of the National Certification and Accreditation Commission. There is no room for shoddy workmanship or inferior materials. It is packaged independently, protecting against moisture and dust, and is convenient for storage and transportation. It meets various requirements for wholesale scenarios. Whether it’s an engineering general contractor, a distributor, or an enterprise with a large demand for high-voltage cables, they can purchase with peace of mind and use with confidence.
