Abstract
Description
Technical Field
[0001] This utility model relates to the field of power cable technology, and more specifically, to a low-voltage power cable with excellent fire resistance. Background Technology
[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors that are internally energized and externally insulated. In a broad sense, wires and cables are also simply called cables, while in a narrow sense, a cable specifically refers to an insulated cable, which consists of one or more insulated cores and their respective possible sheaths, a total protective layer, and an outer protective layer. Cables may also have additional insulating conductors.
[0003] Existing low-voltage power cables are often used in unshaded environments for extended periods. Exposure to sunlight and the heat generated by the internal conductors can easily damage the outer wall of the cable. If rainwater gets in, it will damage the inside of the cable and affect its long-term use. Utility Model Content

[0035] In this embodiment, a grounding wire 2 is set through the grounding port, and the grounding wire 2 serves as the grounding effect.
[0036] Working principle: The inner directional frame 1 sets up the inner forming components, distinguishes them, and strengthens the overall strength. The side filling layer 3 wraps and fixes the low-voltage conductor 4, while also providing protection, heat dissipation, and insulation. The deformation holes allow the side filling layer 3 to deform under external pressure, making it less prone to damage. The outer shaping components shape and protect the inner shaping components.
