On April 27, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Wuxi Xinhongye Cable Technology Co., Ltd. obtained a project entitled "high-power cooling DC charging pile cable and its manufacturing method", with the authorization announcement number of CN107967959B, and the application date of November 2017.

The patent abstract shows that the present invention discloses a high-power cooling type DC charging station cable, which includes: two sets of signal control cables, two main power cores, two backup power cores, and one ground wire. A high thermal conductivity PP filling mesh is added between the core and the core, a layer of thermal conductivity film is wrapped around the core group, and a layer of wear-resistant and corrosion-resistant elastic polyolefin material is wrapped around the thermal conductivity film. The conductors of the two main power cores are twisted by several sets of strands, and a layer of high-temperature resistant PTFE hollow tube is sparsely wound outside the conductor. The PTFE hollow tube is overlapped with a layer of high-temperature resistant PTFE wrapping tape, and the PTFE wrapping tape is wrapped with a layer of high-temperature resistant PTFE wrapping tape. The soft elastic polyolefin material of this high-power cooling DC charging station cable solves the problem of small rated load of the same cross-section of existing charging station cables, The current carrying capacity of the product is 2.5-3 times that of cables with the same cross-section, and its bending resistance, wear resistance, oil resistance, corrosion resistance, temperature range of use, and number of round trips have been significantly improved.
