Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a flame-retardant rubber soft cable for a mining charging pile. Background Art

[0002] Charging pile cable usually refers to the cable used to connect the charging pile and the power system. It plays a key role in transmitting electrical energy during the charging process of electric vehicles. The charging pile cable is responsible for transmitting electrical energy from the charging pile to the battery of the electric vehicle to realize the charging of the electric vehicle.

[0003] In the prior art, when the cable used in the charging pile is charging, the cable itself will generate heat due to the resistance of the line, and because most of the existing charging piles use fast charging, the current inside the cable is large and the voltage is high, which causes the cable to easily generate high temperature during use. In order to reduce the occurrence of accidents, most of the existing cables are usually equipped with temperature measuring units on the cables, but they are easily interfered by external electromagnetic waves during use, resulting in the temperature measurement not being automatically powered off even if overheating occurs. Therefore, a flame-retardant rubber soft cable for mining charging piles is now proposed. Utility Model Content
