Description
technical field:
The utility model relates to optical cable, particularly relates to a kind of elasticity optical cable with companion's heat structure.
background technology:
China is geographical vast, and the north and south temperature difference is large, and especially in the winter time, the outdoor temperature of northeast region-by-region can reach subzero about 50 DEG C.Under this arctic weather condition, ordinary optical cable carries out construction in this condition and lays and just there will be cable insulation and sheath cracking, and this cable is once occur mobile, then insulation and sheath not only ftracture, but also can come off, and conductor exposes and cannot use.This just gives needs the operation of the equipment of mobile operating out of doors to bring difficulty under cold conditions, just cannot run even at all.
Therefore, use under needing cable configuration reasonable in design to meet above-mentioned cold rugged environment, need optical cable to have certain elasticity and plastic yield, ensure that the working temperature of cable core is within rational temperature range, extends its serviceable life simultaneously.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of elasticity optical cable with companion's heat structure, has excellent elasticity and toughness, can long term maintenance within rational temperature range, cable core can continual and steady work.
The technical solution of the utility model is as follows:
With the elasticity optical cable of companion's heat structure, it is characterized in that: comprise anti tear silicon rubber liner core, anti tear silicon rubber liner core is coated with heat conductive insulating elastic rubber sleeve, fiber unit spaced apart is provided with between anti tear silicon rubber liner core and heat conductive insulating elastic rubber sleeve, heating tape is provided with between adjacent fiber unit, heat conductive insulating elastic rubber sleeve is coated with powder separation layer, powder separation layer is coated with aluminium-plastic tape winding layer, and aluminium-plastic tape winding layer is coated with anti tear silicon rubber external sheath layer.
The described elasticity optical cable with companion's heat structure, is characterized in that: described powder separation layer adopts refractory ceramics powder and silicate powder Homogeneous phase mixing to form, and its thickness is generally 0.8 ~ 1.6mm.
The described elasticity optical cable with companion's heat structure, is characterized in that: the thickness range of described heat conductive insulating elastic rubber sleeve is generally 0.15 ~ 2.8mm.
The utility model has the advantages that:
The utility model makes optical cable have excellent elasticity and toughness by anti tear silicon rubber liner core, heat conductive insulating elastic rubber sleeve, simultaneously between fiber unit, heating tape insulated from each other again can long term maintenance within rational temperature range, in addition, optical cable also has excellent waterproof and dampproof performance, the work that cable core energy is continual and steady, long service life.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
See accompanying drawing:
With the elasticity optical cable of companion's heat structure, comprise outer anti tear silicon rubber liner core 1, anti tear silicon rubber liner core 1 is coated with heat conductive insulating elastic rubber sleeve 2, fiber unit 3 spaced apart is provided with between anti tear silicon rubber liner core 2 and heat conductive insulating elastic rubber sleeve 1, heating tape 4 is provided with between adjacent fiber unit 3, heat conductive insulating elastic rubber sleeve 2 is coated with powder separation layer 5, powder separation layer 5 is coated with aluminium-plastic tape winding layer 6, and aluminium-plastic tape winding layer 6 is coated with anti tear silicon rubber external sheath layer 7.
Powder separation layer adopts refractory ceramics powder and silicate powder Homogeneous phase mixing to form, and its thickness is generally 0.8 ~ 1.6mm, and can form hard solid after chance water, block water enters cable core, and its waterproof and dampproof performance obtains the lifting of matter.
The thickness range of heat conductive insulating elastic rubber sleeve is generally 0.15 ~ 2.8mm.
