Provided is a trigger optical cable applied to the field of ultra-
high voltage power transmission. The trigger optical cable applied to the field of the ultra-
high voltage power transmission comprises a core layer, a wrapping layer, a
coating layer, a tight wrapping layer, a reinforced layer and an outer protective layer from inside to outside in sequence. The core layer is of a
solid structure, the wrapping layer wraps the outer wall of the core layer, the
coating layer wraps the outer wall of the wrapping layer, the tight wrapping layer wraps the outer wall of the
coating layer, the reinforced layer wraps the outer wall of the tight wrapping layer, and the protective layer wraps the outer wall of the reinforced layer. The tight wrapping layer is made of Hytrel materials of
flame-retardant level, the outer protective layer is made of fluoroplastics, the reinforced layer is filled with
aramid fibers, and the
refractive index of the core layer is larger than that of the wrapping layer. The trigger optical cable applied to the field of the ultra-
high voltage power transmission does not influence the
transmission performance of the optical cable in the near-
infrared band in an 800nm-1400nm range under the premise that the ultra-high
voltage endurance level and the
flame-retardant level of the whole product are ensured, and is resistant to
corrosion, resistant to high low temperature, inflaming retarding, insulative, resistant to ultra-high
voltage, resistant to treading and free of damage.
