High-power cooling direct-current charging pile cable and manufacturing method thereof

Abstract

The invention discloses a high-power cooling direct-current charging pile cable. The high-power cooling direct-current charging pile cable comprises two groups of signal control cables, two main powercable cores, two standby power cable cores and a ground wire, wherein a PP filling net with high heat-conducting property is added between the wire cores; a heat-conducting film is wound outside thewire core group; the heat-conducting film is covered with a layer of abrasion and corrosion resistant elastomer polyolefin material; a conductor of the two main power cable cores is formed by twistinga plurality of groups of folded yarns; a high temperature resistant Teflon hollow tube is wound outside the conductor sparsely; a high temperature resistant PTFE wrapping tape is overlapped and wrapped outside the Teflon hollow tube; and the PTFE wrapping tape is covered with a layer of high temperature resistant flexible elastomer polyolefin material. The high-power cooling direct-current charging pile cable solves the problem that the equivalent section rated load of an existing charging pile cable is small, the carrying capacity is 2.5 to 3 times of that of an equivalent section cable, andthe bending resistance, abrasion resistance, oil resistance, corrosion resistance, using temperature range and circulating return number of times of the product are greatly improved.

Description

technical field [0001] The invention relates to the field of wires and cables and their manufacture, in particular to a high-power cooling type DC charging pile cable and a manufacturing method thereof. Background technique [0002] With the development of modern industry, environmental problems are becoming more and more serious. New energy electric vehicles are more and more recognized and promoted by countries all over the world. The power source of new energy electric vehicles is batteries, and the capacity and charging time of the batteries have become a new evaluation method. Energy key indicators of electric vehicle performance. At present, the charging of new energy electric vehicles is generally charged on a specific charging pile. The charging pile and the new energy electric vehicle are connected by a connector and a charging pile cable. When the cable passes a certain load current, the conductor will generate heat and cause the cable to heat up. When the cable W...

Problems solved by technology

[0003] The object of the present invention is to provide a high-power cooling type DC charging pile cable and its manufacturing method. This high-power cooling type DC charging pile cable solves the problem of small rated load of the same section of the existing charging pile cables, and the carrying capacity is the same The cross-section is 2.5~3 times that of the cable. At the same time, the product's bending resistance, wear resistance, oil resistance, corrosion resistance, operating temperature range, and cycle times have been greatly improved compared with existing products.
