3 ELECTRICAL TYPE TESTS 3.1 General 3.1.1 Tests at elevated conductor temperature For the tests with the cable system at elevated temperature, a reference loop for temperature control of the conductor was installed. The reference cable was cut from the total cable length submitted by the client intended for the type test. This reference loop was installed close to the main loop in order to create the same environmental conditions as for the test loop. The heating currents in both the reference loop and the test loop were kept equal at all times, thus the conductor temperature of the reference loop is representative for the conductor temperature of the test loop. Annex A, method 1 of IEC 60840 was used as a guide. The tests at elevated temperature are carried out two hours after thermal equilibrium has been established.

3.1.2 Test set-up In order to perform the type test, the following test loop was prepared by the manufacturer's representatives.

Not to scale

The test loop consists of three pieces of power cable type (A2XS(FL)2Y 1 x 800 (g) / 185-110kV, of 3 x 10 m length, two types of outdoor terminations with composite insulators, two GIS-terminations mounted in a back-to-back configuration inside a SF6-gas filled container, one straight-through joint. The above-mentioned cable was supplied by PO Energocomplekt L.L.C., Vitebsk, Republic of Belarus. The above-mentioned outdoor termination and straight-trough joint were supplied Arkasil SK L.L.C., Moscow, Russia. The above-mentioned outdoor termination was supplied by Pfisterer Ixosil AG, Altdorf, Switzerland. The above-mentioned GIS-terminations were supplied by Pfisterer Kontaktsysteme GmbH, Winterbach, Germany. Photographs of the test set up are presented in appendix C.

3.8 Examination

Standard and date Standard IEC 60840 (2004) and HD 632 S2, part 1, clause 12.3.8 Test date 25 November to 1 December 2011 3.8.1 Examination of cable and accessories The examination of the tested cable and accessories was carried out in accordance with clause 12.3.8 of HD 632 S2, part 1. For this purpose a piece of the tested cable was dissected after completion of all the tests. Furthermore, all accessories ends were dismantled by the manufacturer’s representatives and visually inspected by KEMA. Examination of the parts with unaided vision did not reveal any signs of deterioration, which could affect the test objects in service operation. No sign of electrical degradation, leakage, corrosion or harmful shrinkage was found. Photographs are presented in appendix C. Result The cable and accessories passed the test. 3.8.2 Tests of components of cables with a longitudinally applied metal foil
