Cable lines for the Russian railways infrastructure
 
Abstract.
The article presents the technical and performance parameters of cables used for installation along railroads; signal and blocking cable designs are described.
Statistical estimates of cable and wire consumption at the RZD (Russian Railways) facilities, of their production volumes at the Electrocable Association companies and of their application areas are presented.
Key words:
signal and blocking cables; railroad; contact system; contact wire; railway substation.

Development of cable and wire for the RZD railway rolling stock. Experience and future expectations
 
Abstract.
The article describes the development prospects for the RZD (Russian Railways) passenger and freight turnover, as well as the development of the RZD railway rolling stock (electric and diesel locomotives). The range of cable products for the rolling stock and the requirements specified for cable and wire are considered.
Key words:
cable and wire for the RZD rolling stock; power and control cable and wire; equipment cable and wire; cable for digital communication systems; low temperature resistance; oil and diesel oil resistance; fire safety properties.

The effect of the degree of primary protective coating polymerization on the optical fiber mechanical characteristics
 
Abstract.
It was shown that the degree of polymerization of the acrylic primary coating affects its hygroscopic property, which in its turn influences the characteristics measured after the exposure at elevated temperature and humidity.
Key words:
optical fiber; primary coating; UV-curing; stress corrosion resistance.

Mechanical calculation of drop cables
 
Abstract.
The article deals with the FTTH (Fiber To The Home) architecture of a subscriber access network based on the PON (passive optical network) technology. The ОСЦLS-HF drop cable construction with the central polybutylene terephthalate tube filled with hydrophobic gel is presented.
The cable is designed for both outdoor installations along power transmission lines, on contact line masts and electrified railway automatic block systems, and installation inside buildings. A mechanical calculation of the ОСЦLS-HF-1А1 (0.9)-1,2 drop cable construction was performed and mechanical tests of the cable using the РРК-ЕК2 type tensile and crushing setup were carried out. In the course of testing the dependences of the signal attenuation increment in the OF on the tensile and crushing stress values were obtained.
Key words:
optical cable (OC); central optical module; optical fiber (OF); drop cable; FTTH (Fiber To The Home); PON (passive optical network); optical splitters; tensile and crushing stress; mechanical calculation».
