IMPEDANCE BONDS DTSH-1-150 AND DTSH-1-300
Low-maintenance AC impedance bonds of type DTSh are installed inside the track gauge, on railway sections equipped with automatic locking of 25, 75 Hz frequency of marking current in the track circuit, audio frequency track circuits in the frequency range from 420 Hz to 5555 Hz and AC electric traction of 50 Hz frequency.
DTSh are designed for separation and conducting rated (continuous) traction current through each winding section and creation of reactive (inductive) resistance to
fl ow of the marking current.
Impedance bonds upon impact of mechanical loads and climatic factors meet requirements for classifi cation groups MS4 (MS5 for separate elements and components upon fi xation directly to rails) and K4 (UKhL design) correspondingly per OST 32.146-2000.
Degree of ingress protection is IP64 per GOST 14254.
In terms of personnel protection against electric shock the devices are related to class 0 per GOST 12.2.007.0.
• impedance bond design is developed to increase the lifetime, to reduce costs for its maintenance in service, to ensure leak-tightness, anti-vandal design, cost reduction during repair of track superstructure;
• the impedance bond design enables during operation to replace a signal cable without product dismantling;
• impedance bonds are equipped with casings for protection against damages;
• impedance bonds DTSh are low-maintenance products as they operate without oil.IMPEDANCE BOND (IB) DESIGN VERSIONS
