Product Description: This product is suitable for overhead power lines with rated voltages of 1kV and below 10kV, and can be used either as a fixed installation or as service drop cables. The product features weather-resistant cross-linked polyethylene and weather-resistant PVC insulation extruded over tightly compacted copper or aluminum conductors, ensuring safe and reliable performance. Additionally, it boasts excellent mechanical, physical, and electrical properties, including resistance to tracking, surface discharge, and atmospheric conditions. Moreover, the cable allows for tighter installation clearances, helping to save valuable right-of-way space. By reducing line voltage, it minimizes the risk of power supply incidents, thereby enhancing personal safety. This makes the product ideal for use in diverse environments, such as mountainous regions, forested areas, mining zones, and urban settings.
Execution Standard: GB/T 12527-2008; GB/T 14049-2008
Usage characteristics:
Rated voltage: 1kV, 10kV
The long-term permissible operating temperature of cable conductors: PVC-insulated and polyethylene-insulated cables should not exceed 70°C; cross-linked polyethylene-insulated cables should not exceed 90°C.
The installation temperature of the cable should not be lower than -20°C;
For cables with an outer diameter (D) less than 25 mm, the bending radius must be at least 4D. For cables with an outer diameter (D) greater than or equal to 25 mm, the bending radius should be no less than 6D.
