3 Introduction Long terms of cable accessories delivery very often are a big problem for cable lines establishing. That is why there is a great demand of cable accessories for HV cables in the market, with high quality and minimum terms of delivery for the reasonable price. Arkasil SK LLC sets the goal to hold a strong position in the cable business. The main activity of Arkasil is HV accessories kv production and delivery, and also related products such as tools, heat shrinkable components, HV connectors and other products for cable line construction. History Arkasil SK LLC was established in Owing to the unique skills and knowledge of cable business the company could develop cable accessories kv design for a short period of time. The equipment was chosen and the necessary material and components were purchased for the insulating parts production. In 2010 Arkasil SK LLC obtained the production facility in Moscow region, it was renovated and reconstructed to organize the cable accessories 110 kv production. Successful Type Tests At the beginning of 2011 the type tests of the cable accessories 110 kv in accordance to IEC were successfully carried out together with CESI (market leader among the leading international organizations providing measurements and inspection, testing & certification). In autumn 2011, the type tests of Arkasil SK terminations and joints for 110 kv were completed. The tests were performed in the KEMA (the Netherlands) laboratory under the Harmonized European Standard HD 632 S2, part 1, analogue of the IEC 60840, rev. 3 (2004). The company have start long-term tests of the cable system 220 kv together with 220 kv Arkasil cable accessories till the end of 2012.

4 Outdoor termination 110 kv Technical description Outdoor termination MKB 126 / 145 with silicone type insulator uses for the connection of cable line with other elements of power supply systems. Outdoor termination MKВ 126 /145 uses for outdoor and indoor installation, for XLPE cables 64/110 kv with the conductor cross-section up to 2000 mm2. Basic components Insulator silicone type insulator with glass fiber reinforced epoxy resin tube and silicone rubber sheds sheds color light gray top and bottom flanges glued and sealed to the silicone insulator Cable end pre-moulded and factory-tested silicone stress cone cable end base plate branch pipe with flange support insulators seals and fixing materials polybytene insulation oil optical fiber splice box for the connection to the equipment Application Type MKВ 126 / MKB 145 Highest voltage for equipment (Um), kv 126 / 145 Cable conductor cross section range, mm Maximum cable diameter, mm 115 Maximum cable insulation diameter, mm 94 Demands to the electrical parameters: AC voltage withstand test: Partial discharge test: Impulse voltage (10+/10- impulses) Operating temperature range: 160 kv for 30 min / 190 kv for 30 min 5 pc at 96 kv / 5 pc at 114 kv 550 kv / 650 kv -60 С/ +50 С Nominal operating current: limited by cable specification 2

6 Cable clamps To fix the cable near the outdoor termination and joints, BKK cable clamps with the rubber inserts (PST-80) is used. Cable clamps together with rubber inserts exclude the cable longitudinal movement. Type BBK L l h d 65/ / / Flat connectors To connect terminations to the networks, flat connectors should be used. Arkasil SK supplies aluminum, bronze and bimetallic flat connectors. Splice box It is applied for connection of fiber-optical modules. Splice box is a protective metal box, safety class IP66, with 4 inputs for fiber-optical modules, 2,5-5,5 mm in diameter. It protects the connection point and is applied to store the fiber stock necessary for repair or preventive works.

7 Joints 110 kv Technical description Pre-moulded outdoor joint MСВ 126 / 145 is designed to connect two XLPE 64/110 kv high voltage cables. Joint MСВ 126 / 145 could be produced in different constructions which give the possibility of screen wires direct connection, cross-bonding connection of different cable phase wires screen (screen transition), wires screen connection with optical fibers in the metal tubes (modules). Basic components Joint body Silicone pre-moulded joint body with conductive elements for electrical field control Connector and sealing materials One piece pre-moulded silicone joint body Special tapes for different purposes Protective covering from heat shrinkable tubes and sleeves (optionally it other protective covering) Application Type МСВ 126 / 145 Highest voltage for equipment (Um),kV 126 / 145 Cable conductor cross- section range, mm² Maximum cable diameter, mm 115 Maximum cable insulation diameter, mm 91 Technical data Demands to the electrical parameters: AC voltage withstand test: 160 kv for 30 min. / 190 kv for 30 min. Partial discharge test: <5 pc at 96 kv / <5 pc at 114 kv Impulse voltage (10+/10- impulses) 650 kv Operating temperature range: -60 С/+50 С Currency load rating: Rated operational current: Short circuit current: limited by cable specification limited by cable specification 5
