Submarine cable

Description

Supply of subsea cable: — 40 000 mtrs (in single length or sections), — 18/30(36) kV, 3 copper conductors (cross section 400 m m2), — XLPE insulated, — double or single wire armoured, — completed with one (1) interstitial fibre optic cables containing 24/48 fibres. Relevant technical standards: Cable supply cable design standards (where applicable): — IEC 60502: Part 2: Cables for rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV)”, second edition, 2005-03; [4], — IEC 60228: Edition 3.0, 2004/11, — IEC 60038: Edition 7.0, 2009/06. Cable Current Calculations: — IEC 60287-1-1: Part 1-1: Current rating equations (100 % load factor) and calculation of losses, edition 2.0, 2006-12; [7], — IEC 60287-2-1: 2-1: thermal resistance, edition 2.0, — IEC 60949: edition 1.0, 1988, — IEC 61443. Testing: — IEC 60502: Part 2: Cables for rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV)”, 2nd, 2005-03, — CIGRÉ Tech Broch 490: 2012, — CIGRÉ Tech Broch 623. Scottish Hydro Electric Power Distribution plc ("SHEPD") have an emergency requirement for the supply of 40 km of subsea cable [as detailed in II.1.4) above] due to fault on existing circuit. The purpose of this PIN is to establish availability of such a cable for fault rectification. Respondents are requested to urgently contact SHEPD with details of any available cable to stated specification. Due to extreme urgency respondents are requested to submitt any relevant information in advance of the closing date of the PIN where possible.
