AI Technical Summary
Technical Problem
During the working process, existing submarine cables are constantly heating and heat accumulation, which leads to an increase in temperature, damages the cable material, reduces the cable life, and are easily damaged by bending during laying.
Method used
A submarine cable with high bending resistance and long heat dissipation life is designed, using an integral filling structure and hollow integrated filling strips. The groove is designed to fix the photoelectric unit. The hollow structure bears side pressure and stress when bending, and improves heat dissipation performance.
Benefits of technology
It effectively improves the heat dissipation and bending resistance of the cable, extends the life of the cable, and ensures stable operation in complex marine environments.

Abstract
The utility model discloses a submarine cable with bending resistance, high heat dissipation and long service life, compared with a common three-core cable, the structure of a filling strip of the submarine cable is a circumferential integral structure with a gap, the circumference is provided with three optical unit grooves and three electric unit grooves with arc bottoms at intervals, and the optical unit grooves and the electric unit grooves are arranged in a staggered manner. According to the utility model, the depth and width of the groove are well matched with the optical unit and the electric unit, the optical unit and the electric unit do not contact with each other, are clamped in the groove and are not easy to damage, heat dissipation does not influence each other, the heat dissipation performance is good, and the operation temperature is easier to control; the hollow-out structure of the filling strip can bear a part of lateral pressure and stress during bending, and the heat dissipation effect is better than that of a common filling strip structure.
