Overview
Presently, the electrical power lines of the railway transport system are equipped with interrupters and separators outrun both morally and physically, actioned by old systems with low reliability and durability.
Also, the isolation level of the existing equipment is of 80 kV, compared to the 200 kV required by the European norms.
In order to align the electrical system within the Romanian Railways National Company (SNCFR), modern equipment was needed to be designed and implemented, using the best commutation method, i.e. in vacuum commutation, which presents technical characteristics compliant at European level.
The project is financed by the AMTRANS programme, contract 6C10/2003, with the amount of 4.927 billion ROL, with a cofinancing from the project co-ordinator S.C. ICPE S.A. of 3.033 billion ROL, the total amount raising to 7.960 billion ROL.
The project aims to design, achieve and homologate in zero series phase of:
- a system for separating the electrical power lines of the rail transport, at a voltage of 27,5 kV, 630 A using in vacuum commutation, with technical parameters of European level;
- a system of provisioning and protection of the electrical power lines of the rail transport, at a voltage of 27,5 kV - 1250 A using in vacuum commutation, with technical parameters of European level.
Both systems are activated by the most modern system, consisting of an electromagnet equipped with high power permanent magnets, which have a mechanical endurance at least double compared to the classical systems with reinforcing engine and springs.
The project co-ordinator, S.C. ICPE S.A. Bucharest will draft the execution design, execute both systems in its own manufacturing plant and make the type testings.
The Polytechnical University of Bucharest (UPB), will provide technical assistance for establishing solutions, perform the mechanical-cynematical calculations and participate in the type testings.

Results
- Establish the technical sollution for the separation system (SS) 27,5kV-630A;
- Design the expermimental model for (SS). Ellaborate references - draft I;
- Experimental model for (SS) and experiments on the models;
- Design prototypes of the supply system (SA) 27,5kV-1250A-12,5kA and of the separation system (SS). Ellaborate references - draft II;
- Execute prototypes for (SA) and (SS), type tests according to the product Techical Specification (TS), together with development of test reports and certification of prototypes (SA) and (SS);
- Design zero series (SA) and (SS), execute zero series (SA) and (SS), type tests according to the product TS, together with development of test reports and certification of the zero series for (SA) and (SS). The final result is the certification of the zero series for both systems. Further on, the series production can proceed within the Energetical Research & Design Institute - ICPE S.A. without other investments for preparing the manufacture line. For monitoring the operation of the products during the exploitation, it was agreed with the National Railway Company that an interrupter of 27,5kV-1250A be delivered and installed free of charge within the supply system of the latter, in order to enable the participation in the tendering process of 2006, when it is estimated that a number of 40 interrupters will be contracted.
Policy implications
- Design and execute modern equipments using the most recent commutation method, i.e. vacuum commutation, including technical characteristics of European level;
- By replacing the interrupters with oil and the separators in air, obsolete morally and with a low fiability, the new equipments will increase the safe exploitation of passenger and freight transports;
- The vacuum commutation equipments are completely non-pollutant;
- Presently, an SA+SS system is imported with a cost of approximately 15,000 EUR, while the the cost for the equipments produced within this project is expected to be of approximately 10,000 EUR. This leads to savings in amount of 200,000 EUR for 40 systems/ year (40 x 5,000 EUR = 200,000 EUR);
- Approximately 25 new jobs will be created by introducing the manufacture line within ICPE.
