Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a reinforced anti-extrusion cable. Background Art

[0002] As we all know, cables are used in all walks of life, such as the power system: the wire and cable products used in the power system mainly include overhead bare wires, busbars, power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber-sheathed cables, overhead insulated cables), branch cables (replacing some busbars), electromagnetic wires, and electrical equipment wires and cables for power equipment; information transmission: the wires and cables used in information transmission systems mainly include local telephone cables, TV cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communications or other composite cables; instrument systems: this part uses almost all products except overhead bare wires, but mainly power cables, electromagnetic wires, data cables, instrument cables, etc.

However, in the daily use of the cable, the cables placed on the ground are often easily pressed by heavy objects, which may cause damage to the wire core inside the cable, or even cause the wire core to break and ultimately make the cable unusable, thereby reducing the cable utilization efficiency.
