Problems solved by technology

However, since the submarine cable is laid on the seabed, the laying environment is complex, it needs to withstand high pressure for a long time, and it is prone to aging, so the strength and pressure resistance of the submarine cable are extremely important
With the development of the times, the strength and pressure resistance of existing submarine cables have gradually failed to meet the needs of the market.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-strength and pressure-resistant submarine cable material and a preparation method thereof. Background technique [0002] Submarine cables are cables wrapped in insulating material and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern undersea cables use fiber optics to transmit telephone and internet signals. Compared with land cables, submarine cables have many advantages: First, laying does not require digging tunnels or supporting them with supports, so the investment is small and the construction speed is fast; Affected by wind and waves and other natural environments and interference by human production activities, the cable is safe and stable, with strong anti-interference ability and good confidentiality performance. However, because the submarine cab...
