For solving the technical problem, the utility model provides an outdoor central beam tube optical cable, including optic fibre, loose tube and oversheath, its characterized in that, loose intraductal fire-retardant area and many optic fibre of being equipped with, fire-retardant taking has wrapped up by interior insulating layer, shielding layer and fire-retardant layer outward in proper order, loose tube is last to be equipped with the oversheath, the oversheath includes the steel wire armor of the most inboard and the oversheath layer in the outside, wrap up by interior outside to in proper order on the steel wire armor and have water blocking area, steel to mould composite band, outer insulating layer, wearing layer and oversheath layer, be equipped with two stiffeners in the oversheath layer.
Furthermore, the inner insulating layer, the shielding layer and the flame-retardant layer are arranged in the loose tube and used for enhancing the insulating, shielding and flame-retardant performances of the optical cable.
Furthermore, the reinforcing part is two cylindric steel wires for the tensile strength of reinforcing optical cable.
Furthermore, the shielding layer is formed by twisting and winding tinned aluminum wires.
Furthermore, the flame-retardant belt is a glass fiber belt, and has the advantages of low manufacturing cost and good flame-retardant property.
Further, the water-blocking tape is made of a water-blocking polymer.
Furthermore, the outer surface of the steel-plastic composite belt is plated with a layer of zinc to play roles of rust prevention and corrosion prevention, the outer insulating layer is made of an insulating material, the wear-resistant layer is made of rubber fibers, and the outer sheath layer is made of a polyethylene material.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a loose intraductal fire-retardant area and many optic fibre of being equipped with of cover, including internal insulation layer, shielding layer and fire-retardant layer, its loose intraductal design that still is equipped with the oversheath on the cover has simple structure, compactness, waterproof, flame retardant property is good, tensile strength is strong, has improved the life's of optical cable advantage greatly.
