2 Termination 110 kv Technical description Termination MKB 126 / 145 with composite type insulator uses for cable line joints with other elements of power-supply systems. Termination MKV 126 /145 is used for outdoor and inner installation, for XLPE cables 64/110 kv with the conductor cross-section Basic components Insulator composite type insulator with glass fiber reinforced epoxy resin tube and silicon rubber alter-nating sheds color light gray top and bottom flanges glued and sealed to the composite insulator Description Maximum operated voltage, Um Maximum cable insulated diameter Maximum cable sheath diameter Cable conductor cross section range Maximum allowed inclination,angle Termination length, L Creepage distance length Pollution level in accordance with IEC 60137; All Union State standard ; Electrical installation codefkb Volume of pack compaund Weight Maximum allowed force on top connector kv 2 l kg kn MKV 126 / III IV IV ,5 3,5 3,5 Cable end pre-moulded and factory-tested silicon stress cone cable end base plate branch pipe with flange support insulators seals and fixing materials unpressurised synthetic oil as an insulating medium optic fiber outlet for the connection to the equipment Area of application Type MKV 126 / 145 Maximum system voltage, kv 126 / 145 Cable conductor cross section range, Maximum cable sheath diameter, 115 Maximum cable insulation diameter, 94 Demands to the electrical parameters: AC voltage withstand test: Partial discharge test: Impulse voltage (10+/10- impulses) Environmental characteristics: Climatic category: Nominal operating current: limited by cable specification 160 kv for 30 min / 190 kv for 30 min 5 pc at 96 kv / 5 pc at 114 kv 550 kv / 650 kv YUHL1 Stress cone routine tests for MKB 126 / MKB 145 Test voltage level: 160 kv for 30 min / 190 kv for 30 min Partial discharges level: <5pC at 96 kv / <5pC at 114 kv Support insulator withstand voltages: AC voltage: 10 kv DC voltage: 20 kv Mechanical characteristics: Maximum allowed inclination with vertical: 30 C Approximate weight, kg: 115 Maximum allowed force on top connector, H (horizontal): 3500

3 Additiory Cable clamps To fix the cable before the termination and joints, we need the BKK cable clamps with the rubber inserts (PST-80), which exclude the cable longitudinal movement. Type BBK L l h d 65/ / / Joints 110 kv Technical description The pre-moulded outdoor joint MSV 126 / 145 is designed to connect two extruded high voltage cables XLPE 64/110 kv. Joint MSV 126 / 145 could be produced in different ways which admitted the possibility of screen wires direct connection, cross-bonding connection of different cable phase wires screen (screen transposition), wires screen connection with optical fibers in the metal tubes. Basic components Insulator Silicon pre-moulded joint body with elements for electrical field control Connector and sealing materials One piece pre-moulded silicone insulator Special tapes for different purposes Protective covering from shrinkable tubes and sleeves (optionally it is possible to order other protective covering) Contact clamps To connect terminations to the networks, we need to apply contact clamps. Arkasil SK supplies aluminum, bronze and bimetallic contact clamps. Area of application Type MSV 126 / 145 Maximum system voltage, kv 126 / 145 Cable conductor cross section range, ² Maximum cable sheath diameter, 115 Maximum cable insulation diameter, 91 Technical data Splice box It is applied for connection of fiber-optical modules installed in the high-voltage cables screens. Splice box is a protective metal tray, safety class IP66, with 4 inputs for fiber-optical modules, 2,5-5,5 in diameter. It protects the connection point and is applied to store the fiber stock necessary for repair or preventive works. 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 Environmental characteristics: Climatic category Currency load rating: Rated operational current: Short circuit current: limited by cable specification limited by cable specification YUHL1
