IEC 60502 Standard Three Core Cables
Nhạc trưởng: Dây dẫn bằng đồng hoặc nhôm ủ phẳng.
Conductor shielding: The conductor shielding shall be non-metallic and shall consist of an extruded semi-conductive compound with a semiconductor strip applied on top of the semiconductor compound. The conductor shield is not required for PVC, EPR/HEPR insulated cables in the 1.8/3KV to 3.6/6KV range.
Cách nhiệt: 1.8/3KV and 3.6/6KV cable ranges are generally insulated with PVC, but can also be insulated with XLPE, EPR/HEPR.

Ứng dụng:
Three-core cables are designed for power distribution from 3.6/6.6KV to 19/33KV at 50Hz. They are mainly used in a wide range of applications such as power supply stations, ống dẫn trong nhà, ngoài trời, buried and in water, cũng như cho việc lắp đặt cáp cho ngành công nghiệp, trạm phân phối, và cáp trạm điện.
