Conductive slip ring technology in harsh environments

Tolerance to extreme temperatures is an important fundamental performance of many electromechanical equipment. As a widely used component in electromechanical equipment, slip rings also need certain performance to resist high temperatures or low temperatures. For example, conductive slip rings in some construction machinery used specifically in extreme conditions require temperature resistance of the slip rings to meet the needs of operation in the extremely cold regions of Siberia and the tropical rainforests of Brazil. In addition, there are many electromechanical equipment used in special environments with artificially set high temperatures, so the conductive slip rings used in these equipment naturally need to have the same temperature resistance as the equipment. In order to achieve the corresponding level of high temperature resistance and low temperature resistance, these conductive slip rings are more stringent than ordinary conductive slip rings in selecting key components such as housings, bearings and brush wires.

In order to withstand the harsh environment, JINPAT Electronics developed high temperature resistant conductive slip ring for high temperature rollers. This slip ring works in an environment with constant temperature above 100°C for a long time. In order to develop this product, JINPAT cooperated with the incubator manufacturer specially to develop an ultra-high constant temperature life test bench, and completed the complete life test in several months. With experience in developing constant temperature conductive slip rings and high-temperature rollers above 100°C, JEPAT Electronics has recently developed a conductive slip ring that can operate in a high-temperature silicone oil environment above 200°C. Its model is LPT012-0802-HT, which is a relatively small product. At the same time, in order to better monitor the wear of the friction pair of the conductive slip ring, this kind of product is designed with a hole on the shell, which is similar to the ultra-fast conductive slip ring developed by JINPAT Electronics, but the two have different uses. The former can be used for monitoring, and the latter is used for monitoring, dissipating heat and introducing cool air.
