(One) Product Name 6~35KVCross-linked polyethylene insulated power cable Product Standards This product is manufactured in accordance with the GB/T12706 standard "Copper-core and Aluminum-core Power Cables with Plastic Insulation for Rated Voltage Up to and Including 35KV," and can also be produced according to customer requirements using international standards recommended by the IEC, British standards, German standards, and American standards. Application Scope This product is suitable for distribution and transmission lines with rated voltage of 3.6/6KV to 26/35KV, used for delivering electrical energy. Utilize Features Line Frequency Rated Voltage U0/U: 3.6/6 kV to 26/35 kV. The allowable long-term high operating temperature for the cable conductor is 90°C. During a short circuit (duration not exceeding 5 seconds), the high temperature of the cable conductor does not exceed 250°C. The environmental temperature during cable laying should not be below 0°C. Cable bend radius: Not less than 15 times the cable outer diameter for a three-core cable. Single-core cable shall not be less than 20 times the diameter of the cable.

Cross-linked polyethylene insulated lead sheathed polyethylene jacket power cable Model Specs Voltage Usage Utilize Features The cable conductor is designed for a long-term working temperature of 90°C, with an emergency overload working temperature of 130°C.NoteDuring a short circuit (time ≤ 5 seconds), the conductor reaches a high temperature of 250°C. Note: There is no unified overload duration regulation for power departments in our country; the U.S. standard stipulates that when the load exceeds the rated load by 10%, the duration should not exceed 15 minutes. The ambient temperature during cable installation should not be below -20°C, and the cable should be preheated during installation. Cable minimum bend diameter: Cable Type Bent Diameter Metal sleeve cable After installation 30D0 Installation process 40D0 Note: D in the table0Actual outer diameter for cables. Axial Allowable Tension Force During Cable Installation (not considering radial side pressure at turns) T=K*Core Number * Section Area (kg) Coefficient K value: 7 for copper cores, 4 for aluminum cores. Permitted lateral pressure P during cable bending Single-core cables require a P≤500 kg/m. P=T/R(T represents the axial traction force, R stands for the bending wheel radius) From the above equation, it is apparent that since traction is generally determined by cable length and weight, to ensure P meets the specified requirements, the diameter of the turning wheel should be increased. Cable laying is not restricted by落差. Production Range Model Core Count Cross-section YJLW02 YJLLW02 1 240-2400 YJLW03 YJLLW03 YJQ02 YJLQ02 YJQ03 YJLQ03
