Abnormal Temperature Rise Of Cable Terminals
Publish Time: Author: Site Editor Visit: 8
The temperature rise of Aluminum Cable Lug is not accidental, but a high-temperature state formed by the combined effects of load current, contact conditions and environmental conditions.
The contact surface between Compression Cable Lug and the cable is a critical node for power transmission; this location generates resistance heat due to current flow. If the contact between cable lugs and the cable is not tight, the increased contact resistance will cause localized heat accumulation, resulting in phenomena such as the darkening of the color and decreased metallic luster of wire lugs.
