Abstract
The utility model provides a fire-retardant optical cable of high performance, includes cable core and oversheath, sets up optic fibre and sleeve pipe, central reinforcement, filling rope and fire-retardant cable cream in the cable core, sets up fire-retardant layer, armor between cable core and oversheath, the utility model discloses fire behaviour is good, also can not damage the optic fibre in the cable core under the condition of strong fire burning or long-time firing, can maintain normal communication.
Description
Technical field
The utility model relates to a kind of communications optical cable, especially fire-retardant cable.
Background technology
Existing fire-retardant cable only relies on fire-retardant oversheath to strengthen its fire resistance, and the optical fiber under the situation of strong fire burns or long-time calcination in the optical cable is easy to be damaged, and influences proper communication.
Summary of the invention
In order to overcome the deficiency of existing fire-retardant cable, the utility model provides a kind of High Performance Fire-retardant Optical Cable, and fire resistance is good, also can not damage the optical fiber in the cable core under the situation of strong fire burns or long-time calcination, can keep proper communication.
The High Performance Fire-retardant Optical Cable that the utility model provides comprises cable core and oversheath, and cable core contains optical fiber and sleeve pipe thereof, central reinforce member, gasket for packing, and fire-retardant cable cream is set in cable core, between cable core and the oversheath flame-retardant layer is set.
For further improving intensity of the present utility model and strengthening fire resistance, can between flame-retardant layer and oversheath, armor be set.
The beneficial effects of the utility model are: since set up fire-retardant cable cream on the basis of existing flame retardant type oversheath and be coated on cable core and oversheath between flame-retardant layer and armor, strengthened fire resistance of the present utility model, under the situation of strong fire burns or long-time calcination, can not damage the optical fiber in the cable core, can keep proper communication.
