Problems solved by technology

Therefore, the protection of internal optical cables is still not enough, and the armor layer must be an even number of layers, which undoubtedly increases the weight of the umbilical cable
[0006] CN104103346A discloses an umbilical cable, which provides a solution to strengthen the traditional umbilical cable with a braided structure and parallel fibers, but there is no helical reinforcement of the outer umbilical cable wire make improvements
The degree of lightweight still cannot meet the corresponding requirements

Abstract

The invention relates to the technical field of photoelectric umbilical cables, in particular to a light-weight and high-strength photoelectric umbilical cable. The cable comprises a photoelectric unit and further comprises a flexible sheath used for wrapping the photoelectric unit, and an odd-number-layer braided structure reinforcing body used for reinforcing the modulus and the strength of the umbilical cable in the longitudinal direction is embedded in the flexible sheath. The light weight is remarkable, the longitudinal modulus is large, the protectiveness is high, the bending radius is small, and the flexibility is good.

Description

technical field [0001] The invention relates to the technical field of photoelectric umbilical cables, in particular to a lightweight and high-strength photoelectric umbilical cable. Background technique [0002] The umbilical cable, as a key component connecting the subsea robot for exploration or production operations and the control platform on the sea level or on land, plays a key role in many aspects in terms of power, signal, and material transmission. The main function is to provide signals for underwater equipment The supply of materials related to power, exploration and production is known as the "lifeline" of the seabed and is widely used in the fields of marine scientific research and marine production. Modern deep-sea oil recovery technology has broken through the limitation of platforms, and achieved efficient oil recovery by arranging oil production systems such as Christmas trees on the seabed. The signal control related to the subsea oil Christmas tree on th...
