AI Technical Summary
Existing industrial cables have poor compressive strength, making them prone to damage when multiple cables are stacked or subjected to external pressure, which affects the stability and safety of industrial production.
The design incorporates pressure-resistant and heat-insulating components, including an outer support ring, an arc-shaped support ring, buffer rubber, an inner support ring, heat-dissipating copper foil, and heat-insulating iron tiles, forming a stable support structure to ensure that the cable is not damaged under pressure. The heat-dissipating copper foil dissipates heat quickly, while the heat-insulating iron tiles insulate against heat at high temperatures.
It improves the cable's compressive strength, ensuring that the cable is not damaged when multiple cables are stacked, thus enhancing the stability and safety of industrial production, while also guaranteeing the cable's heat dissipation efficiency and service life.
