Scope and field of application

DTE-0.6-1500 SN impedance bonds fully comply with the technical requirements of TU 32 ELT 117-19. These are used in signalling, interlocking and blocking systems of railway signalling and telecommunication equipment for movement of heavy-tonnage freight trains, high speed passenger trains and on mountain railways in temperate and cold climates (UKhL) with location category 1 according to GOST 15150-69.
Impedance bonds are manufactured in a polymer casing and filled with a heat-conducting compound. They are installed on railway sections with DC electric traction and connected to track circuits at frequencies of 25–5,000 Hz.
