AI Technical Summary
When the load current of existing cables increases, the surface temperature rises, which can easily cause the outer sheath of the conductor to soften and break, thereby reducing the service life.
An anti-overheating cable is designed, which adopts a heat dissipation component consisting of an armor layer and a flexible insulation layer. The expansion body expands when the preset temperature is reached to form a gap to reduce heat conduction, and the heat is dissipated by contact between the thermal conductive strip and the air.
Effectively reduce cable temperature, avoid overheating and damage to the flexible insulation layer, and increase cable service life and heat dissipation effect.
