Abstract

The invention discloses a smart energy port machine low-pressure roller cable and a production process thereof. The cable is sequentially composed of a reinforcing core, power cable cores, a sheath reinforcing layer and an outer protection layer from inside to outside. The reinforcing core comprises a reinforcing core conductor and a reinforcing core insulating layer. The power cable cores are five strands of insulating wire cores and are wound around the outer side of the reinforcing core. Each strand of insulating wire core comprises a power cable core conductor and a power cable core insulating layer. The sheath reinforcing layer is sequentially composed of a first sheath layer, a first aramid fiber yarn woven reinforcing layer, a second sheath layer, a second aramid fiber yarn woven reinforcing layer, a third sheath layer and a third aramid fiber yarn woven reinforcing layer from inside to outside. The cable has the advantages of being reasonable in structural design, resistant tobending and winding, excellent in tensile performance and the like.

Description

technical field [0001] The invention relates to a cable, in particular to a low-voltage reel cable for smart energy port machinery and a production process. Background technique [0002] 90% of global trade is carried out by sea, so the growth of the global economy and trade volume is the main driving force for the development of ports. With the country's emphasis on inland waterway transportation and coastal ports, and the continuous increase in port throughput, the port equipment market will usher in a new round of growth. The number of port machinery low-voltage reel cables used in conjunction with it has increased sharply, but ordinary port machinery low-voltage reel cables usually suffer from various damages, broken cores and other failures after a few months of use, and need to be replaced frequently, which not only increases the cost of use, but also seriously Affecting work efficiency, it is imperative to develop a low-voltage reel cable for port machinery. Conten...
