Special cables for fire safety systems
The paper deals with the issues regarding the development of special cables for fire safety systems in view of the increased requirements for the technology of high-speed and safe communication under the conditions of cable network exposed to fire. The development of the target-focused technology of security and fire alarm system management and its further decentralization provided means for the development of several series of high-tech cables having the necessary characteristics to ensure reliable high-speed communication both under normal mode and fire risk conditions. The author describes the designs and characteristics of modern fire resistant and non-fire proof cables for fire alarm systems and high-speed interfaces of evacuation management and fire fighting systems. Comparative characteristics of the maximum range of the desired quality information transmission are given.

Assessment of the impact of silicone rubber deformation on the electric field distribution in high-voltage terminations and joints
The procedure for the assessment of the impact of silicone rubber deformation on the electric stress distribution in terminations and joints was developed. It is shown that the deformation of such does not result in inadmissible change of the electric field stress when the 220 kV 1600-2500 mm2 power cable is terminated and jointed using commonly applied in practice methods.
