Property, the All Dielectric self-support used suitable for transmission line of electricity.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of all dielectric self-supporting protection against rodents light
Cable, including strengthening core and several fiber units form cable core, and several fiber units are uniformly stranded in around strengthening core, institute
State filling cable cream between fiber unit and strengthening core；The fiber unit includes protective case and several light for being placed in protective case
Fibre fills fiber paste between optical fiber and protective case；Further include extrude held in the sheath outside cable core lotus enhancement layer surface covering it is anti-
Outer after mouse protective layer to be around in the sheath, described hold extrudes outer jacket outside lotus enhancement layer, and the material of the protection against rodents protective layer is
Fibre reinforced composites, the fibre reinforced composites are filled in the gap for holding lotus enhancement layer and sheath, outer jacket
In.
Further, the material of the strengthening core is glass fibre.
Further, the material of the protective case is polybutylene terephthalate (PBT).
Further, the material of the sheath is polyethylene.
Further, paraphenylene terephthalamide's m-phenylene diamine (MPD) (aramid fiber) between the material for holding lotus enhancement layer is.
Further, the outer jacket is resistance to electric trace outer jacket made of resistance to electric trace plastics.
Further, the outer diameter of the resistance to electric trace outer jacket is 13~14mm.
Further, which is characterized in that the core number of several fiber units is 2 cores or more.
Further, setting is fitted closely between the fiber unit.
The utility model has the advantages that the utility model has the excellent performances such as light and hard, non-conductive, high mechanical strength, corrosion-resistant；It holds
Lotus enhancement layer use aramid fiber material, have superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, it is light-weight, insulation, it is anti-aging,
The excellent performances such as life cycle length, the tightly packed fibre reinforced composites in the gap for holding lotus enhancement layer form protection against rodents and protect
Sheath, protection against rodents protective layer and the combination for holding lotus enhancement layer design, it is ensured that the optical cable is especially safeguarded in plague of rats area, without subsequent
Long-term safety uses under strong electric field environment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
