In the prior art, photoelectric composite railway digital signal cable comprises cable core, have loose tube fiber unit and inner shield quad in the cable core, and in actual applications, this cable is subject to the erosion of water and moisture, and particularly hydrogen loss easily takes place when being subjected to the erosion of water and moisture the optical fiber in the fiber unit, influence the optical signal transmission quality, can cause fiber break when serious, cause the security reliability of railway digital communication relatively poor, and can shorten the useful life of cable.
Summary of the invention
The purpose of this utility model provides a kind of photoelectric composite railway digital signal cable, and it can stop water and moisture to enter in the cable core.
The technical solution of the utility model is: a kind of photoelectric composite railway digital signal cable, comprise cable core, described cable core comprises many group holding wires, at least one group of described holding wire is the inner shield quad, and also having one group of described holding wire at least is the loose tube fiber unit, be filled with the cable core greasy for preventing water in the space between described each holding wire, be surrounded by inner restrictive coating, outer waterstop, aluminium sheath layer, metal armouring layer, external sheath layer successively in described many group holding wires outside, have waterproofing hot melt glue line between described metal armouring layer and the aluminium sheath layer.
Described inner restrictive coating inboard is provided with interior waterstop.
Described inner shield quad comprise four mutually stranded single lines, vertically wrap in described four single lines outside screen, be bonded in the plastic sheath layer in the described screen outside, be filled with many water blocking yarns in the space between described each single line.
Described loose tube fiber unit comprises loose jacket layer, is arranged at the multifiber of described loose jacket layer inboard, is filled with the fiber unit greasy for preventing water in the space between described each optical fiber.
Described waterproofing hot melt glue line is sealing adhesive respectively mutually with metal armouring layer, aluminium sheath layer.
Described external sheath layer is sealing adhesive mutually with the metal armouring layer.
The utility model compared with prior art has following advantage: fill greasy for preventing water between each holding wire in cable core, this greasy for preventing water can intercept water and moisture outside, and the setting of outer waterstop and waterproofing hot melt glue line, can prevent further that again sealing and moisture corrode cable core, thereby can ensure long-term safety, the reliability of railway digital communication, and the useful life that can improve cable.
