A light high-temperature-resistant buoyancy cable for a seaplane comprises an outer protective layer, a waterproof layer, a water blocking tape and a cable core; wherein: the cable core comprises an insulation core wire and a filler core, a waterproof layer is wrapped outside the cable core, a water blocking tape is arranged outside the waterproof layer, and an outer protection layer is extruded outside the water blocking tape.

Furthermore, the insulating heart yearn includes silver-plated copper conductor, insulating layer, shielding layer and low density PTFE around the covering sheath, and the insulating layer is extruded in the outer melting of silver-plated copper conductor, and the insulating layer is around the covering shielding layer outward, and the shielding layer is around the covering sheath outward around the low density PTFE.

Furthermore, the insulating layer is a fluorinated ethylene propylene foamed insulating layer.

Furthermore, the shielding layer is a hot-melt polyester aluminum film.

Furthermore, the filling core is a fluorinated ethylene propylene foaming filling core.

Furthermore, the waterproof layer is made of water-blocking yarn materials by a three-section gradual-change type extrusion process.

Further, the outer sheath material is foamed polyurethane.

The utility model discloses beneficial technological effect:

1) The utility model has the advantages of simple integral structure, the function is reliable, and the characteristics of inside high temperature resistance when being applicable to the operation of seaplane and from floating characteristics when the aquatic operation have satisfied the all-weather operation requirement of seaplane.
