APPLICATION:
The standard power single-core cables have a voltage range from 3.8/6.6KV to 19/33KV and a frequency of 50Hz. they are mainly used in a variety of places such as power supply stations, qapalı və açıq döşəmə, in pipelines and tunnels, in mines and shafts, in direct burial in the soil and underwater at the bottom of the sea, və s. They are capable of withstanding considerable pressures and mechanical external forces, and axial tensile forces.
