Anti-resonance photoelectric composite cable and application thereof

Abstract

The invention provides an anti-resonance photoelectric composite cable and application thereof. The anti-resonance photoelectric composite cable comprises a special-shaped anti-resonance cable core, and the special-shaped anti-resonance cable core is sequentially coated with a Kevlar fiber wrapping reinforcing layer, a double-layer forward and reverse wrapping glass fiber reinforcing band layer and a high-density polyethylene and nylon double-layer co-extrusion reinforcing sheath layer from inside to outside; therefore, the stress can be effectively balanced, the resonance effect can be eliminated, the stability of the cable core is excellent, the compression resistance of the photoelectric composite cable is improved, and the service life of the photoelectric composite cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of photoelectric composite cables, in particular to an anti-resonance photoelectric composite cable and its application. Background technique [0002] As an important national infrastructure and popular means of transportation, high-speed rail has played an important role in China's economic and social development in recent decades. Although my country's high-speed railway started late, it has developed rapidly. Through the introduction of foreign technology and re-innovation, it has been able to fully possess the ability to independently build high-speed railways, and has developed rapidly in just a few years. my country has become the country with the fastest development of high-speed railway in the world, the most complete system technology, the strongest integration capability, the longest operating mileage, the highest operating speed, and the largest scale under construction. At present, my country ma...

Problems solved by technology

[0006] (1) The traditional communication optical cable adopts a central tube or layer-stranded structure, and uses a plastic PBT loose tube as the optical unit. The outer diameter of the tube is only about 1.8mm, and the remaining length of the optical fiber in the tube is unstable. Difference;

[0007] (2) In the traditional communication optical cable, the steel wire reinforcement used will aggravate the vibration effect of the optical cable under the high-frequency vibration state;

[0008] (3) Traditional communication optical cables are generally armored with thin steel strips or aluminum strips. After absorbing moisture, the mechanical properties become poor, and the stress cannot be resolved in the resonance state, resulting in important data loss or signal interruption;

[0009] (4) Traditional communication optical cables use ordinary PE sheaths, which have poor tear resistance and are damaged by friction in a high-frequency vibration environment, which affects the life of the optical cable
