Production of equipment for signaling control systems on railway transport

Plant of communication technology and automation

Development and production of equipment for signaling control systems on railway and underground railway transport systems. Quality guaranteed! 

Scientific Industrial Enterprise “Plant of communication technology and automation” (“ZTZA” PE SIE) is the only Ukrainian manufacturer of neutral electromagnetic relays and relay boxes of electric interlocking. The main business lines of the Scientific Industrial Enterprise «Plant of communication technology and automation» include research and development works, development and production of equipment for signaling control systems on railway and underground railway transport systems.

The following equipment is produced at the company:

  • all kinds of crossover cable assembly system cabinets;
  • relay and battery cabinets of all modifications;
  • neutral electromagnetic relays;
  • contactless electronic relays;
  • relay blocks of the executive group;
  • plug in rack-mounted units of different types and modifications;
  • cable cabinets;
  • power-down boards, including those controlled remotely;
  • line boxes and cable coupling sleeves;
  • building-out and blocking networks;
  • cable ladders;
  • level crossing signaling system boards;
  • tonal rail circuits equipment;
  • jacks and distribution panels;
  • adjustable resistors and a number of other products.

production of equipment for signaling control systems on railway and underground railway transport systems

As of today, the company’s product portfolio reaches more than three hundred items and continues to expand.

Scientific Industrial Enterprise «Plant of communication technology and automation» («ZTZA» PE SIE) is the only Ukrainian manufacturer of neutral electromagnetic relays and relay boxes of electric interlocking.

Each type of product undergoes a complete cycle of performance and investigation tests under the supervision of the Department of Automation and Telecommunication of the JSC «Ukrzaliznytsia». Department of Automation and Telecommunication granted the Signal Telephone and Telegraph Departments permissions to use all types of products on the railways of Ukraine.

The «ZTZA» PE SIE in close cooperation with the Department of Automation and Telecommunication successfully carried out a seven-year package of measures to create such products as compact neutral electromagnetic relays (61 items), relay boxes of electric interlocking (17 items). These products are basic items in the signaling control systems on a rail transport system and until recently were supplied only from the Russian Federation. Besides, relays produced at the «ZTZA» PE SIE have several advantages over existing:

production of equipment for underground railway transport systems

  • relay housing is made of non-combustible materials;
  • transparent casing does not tarnish and retain its properties during the whole period of its use;
  • external relay contacts are wedge-shaped, protecting cabinet socket contacts against crushing;
  • electrical and mechanical characteristics of relay remain throughout the whole period of its use, which is confirmed by reliability and endurance tests.

These benefits also apply to all units produced by the «ZTZA» PE SIE in the gear oil pump relay housings. For instance, time delay units, ground alarms, pulsegenerating units, electronic relays and other plug in rackmounted units.

Also, the Enterprise is constantly working to develop electronic blocks and relays. According to the technical requirements of the Department of Automation and Telecommunications, the Company has already designed, conducted tests and obtained a permit for application of time delay digital units of the second generation TDDU-D2 (BVMSh-Ts2). Among the advantages of these units is a large number of gradations of time delay, from 2 seconds to 6 minutes with a pitch of 2 seconds, remotely controlled alarm system signaling about potential problems and resistance to power supply voltage fluctuations.

For a long period of time, the Company has been mass producing universal digital ground alarm systems GAS-DU (SZI-TsU). Their peculiarity consists in the fact that they replace the GAS-1M (SZI-1М) and GAS-1M (SZI-2М) types alarm systems and they can work with alternating (24V, 220V), constant and rectified not stabilized (12, 24, 60 and 220V) voltage of the controlled voltage source.

The company recently successfully completed operational test of the electronic relay TSH-65Е. As part of the operational test, reliability test, during which relay components in-service failures were artificially simulated, has been carried out. As a result, it was proved that relay does not lead to critical failures (switching of more clear light signal) in the case of failure of the relay components. Relay successful without failure has been operating in areas, where mechanical analogs of this type of relay had accelerated wear of contacts.

Electronic pulse relays PRR (IVB) and PR-1700E (IMSh-1700E) has been certified. Circuit design is meant to prevent failures such as continued work of normally closed relay channel in pulsed mode (13-33 contacts) in case of breakdown of normally open channel (33-53 contacts), while working in the code switching mode in AC or DC track circuits. Relays can replace mechanical relays of these types upon condition that additional supply voltage is provided.

In late 2016, according to the results of successful operation testing and registration of technical conditions, the «ZTZA» PE SIE obtained from the Department of Automation and Telecommunications a permit for application of pulse-generating units PGU-1 (DIM-1) and PGU-2 (DIM-2). Unlike similar units from other manufacturers, in these units modern element base that meets modern standards is used.

Moreover, the Company does not forget to support the products that are commercially available for many years. The Company constantly modernizes and adapts its products to meet new regulatory requirements and customer wishes. For example, new design of crossover cable assembly system cabinets is under development now.

Scientific Industrial Enterprise «Plant of communication technology and automation» successfully cooperates with companies from Ukraine, Georgia, the Czech Republic and Germany.

Production of the «ZTZA» PE SIE is distinguished by high quality, as evidenced by reviews on operation, testing, including certification testing. This is confirmed by certificates of conformity for such products as: neutral electromagnetic relays, crossover cable assembly system cabinets, metal relay and battery cabinets, level crossing signaling system boards, relay blocks of the executive group and contactless pulse relays.

Thanks to intelligent and maximum use of its sources and reserves, the Enterprise provides:

  • guaranteed quality products;
  • competitive market value;
  • guarantees of compliance with the agreements on production and delivery terms;
  • meets the requirements and expectations of the customer.

Products manufactured by the Enterprise are now successfully working at the rail transport facilities.

In 2013, the «ZTZA» PE SIE received a Certificate for quality management system, which confirms the compliance of the Enterprise’s quality system with the requirement of DSTU ISO 9001:2009.
