Direct current impedance bond DTE-0.4-1500 P

Back

Scope and field of application

DTE-0.4-1500 P DC impedance bonds fully comply with the technical requirements of TU 32 ELT 006-12. These are used in signalling, interlocking and blocking systems of railway signalling and telecommunication equipment with increased traction current and increased current asymmetry 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.
