Preferably, the conductor is stranded from 37 strands of tin-plated wire.

Preferably, the single mode fiber is an ultra-micro stainless steel hose fiber.

Preferably, the insulating layer is a high-strength ethylene propylene insulating layer.

Preferably, the insulation reinforcing layer is made of aramid fiber materials.

Preferably, the outer sheath is a high-strength anti-aging polyurethane material.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the improved structural design and the accurate material selection ensure that the flat cable is safer to use in frequent bending and under the condition of certain tensile force, has longer service life, and further ensures the safety of the cable and reduces the maintenance and use cost of the cable due to excellent oil resistance, chemical performance and cracking resistance.

2. The cable has the characteristics of super rolling extrusion resistance, bending resistance, abrasion resistance, oil stain resistance, ultraviolet ray resistance, tension resistance, corrosion resistance, tensile aging resistance, low-temperature cold resistance, water resistance, flame retardance and the like;

3. can withstand long-time winding dragging movement and has extremely excellent tensile force characteristics, insulation and pressure resistance, winding and pressure resistance, wear resistance and the like.
