www.AFLglobal.com 52 SKYWRAP ® PHASE WIRE HARDWARE A full range of hardware is available for fixing the SkyWrap cable to phase wire tower arrangements. The cable is passed around and kept away from conductor fittings using a specially designed bypass accessory known as ‘balehanger’. SkyWrap cable is passed down the tower to joint enclosures or termination joints via a specially design system called Phase-to-Ground. This system provides electrical isolation and mechanical support to transition the SkyWrap cable from phase conductor to a tower mounted enclosure. Conductor mounted enclosures or ‘donuts’ are also available for SkyWrap cable, this enclosure is held at the same electric potential as the conductor keeping the joint protected by the Faraday Effect. Hardware fittings are available for tension and suspension tower designs using lattice towers, wood, steel or concrete poles. • Robust weather-proof track resistant designs to suit environmental and polluted conditions • Available for up to 288 fibres • Tower mounted enclosure boxes are 830 x 380 x 260 mm and are made to BS EN 50411-3 standard • Meets IEEE standard 1591.3 • Phase-to-Ground complies with IEC 60 and IEC 1109 standards • Donut complies with IEC 60060-1, IEC 61109, IEC 60437, BS 5049 part 2-994, CISPR18-2 standards • Joint enclosures made to BS EN 50411-3 standard • Suitable for up to 300 kV system voltage FEATURES KEY ACCESSWRAP COMPONENTS FOR SYSTEM VOLTAGES UP TO 50KV Tower mounted Joint enclosure Phase-to-ground Insulator Conductor mounted Joint case Balehanger Section Pole Insulator KEY COMPONENTS FOR SYSTEM VOLTAGES UP TO 300KV Tower mounted Joint enclosure Phase-to-ground Insulator Conductor mounted Joint case Balehanger Tower mounted Joint enclosure Phase-to-ground Insulator Conductor mounted Joint case Aluminium balehanger KEY COMPONENTS FOR SYSTEM VOLTAGES UP TO 150KV www.AFLglobal.com 53 SKYWRAP PHASE WIRE HARDWARE ORDERING INFORMATION ARRANGEMENT TOWER HEIGHT metres STRUCTURE TYPE CONDUCTOR SIZE mm Double Wrap FIBRE COUNT System kV < 25 < 35 < 60 Lattice Tower Steel/ Concrete Pole Wood Pole Tension Suspen - sion 9-22 20-31 30-43 42- 60 12-144 1 Inline Joint 50 TCD L M H - 1016 1016 - - A B C - D nnF 150 TCD L M H 912 916 920 - - A B C - D nnF 300 TCD - - - 301 - - - - B C D D nnF 2 Tension bypass 50 TCD - - - - 1010 1010 - - A B C - D - 150 TCD - - - 927 927 927 - - A B C - D - 300 TCD - - - 308 - - - - B C D D nnF 3 Suspension bypass 50 TCD - - - - 1009 1009 - - A B C - D - 150 TCD - - - 926 926 926 - - A B C - D - 300 TCD - - - 303 - - - - B C D D nnF 4 Termination joint 50 TCD L M H - 1017 1017 - - A B C - D nnF 150 TCD L M H 913 917 921 - - A B C - D nnF 300 TCD - - - 302 - - - - B C D D nnF Conductor mounted joint 50 TCD - - - - 1025 1025 - - A B C - D - 150 TCD L M H - - - 924 925 A B C - D nnF 300 TCD - - - 306 - - - - B C D D nnF Example: TCD-L916BD48F or TCD-927A TYPICAL TOWER ARRANGEMENTS IN-LINE JOINT TENSION BYPASS SUSPENSION BYPASS TERMINATION JOINT 1 2 3 4
