MPP pipes, also known as MPP power cable protection pipes, are available in excavation and non-excavation types. The non-excavation MPP pipe is also referred to as MPP jacking pipe or拖拉管 (drag pipe). These pipes are made primarily from modified polypropylene and feature high-temperature resistance and ability to withstand external pressure. They are suitable for medium and low-voltage power transmission cables with voltage below 10KV.
