Aerial Bundled Conductor SIP1 SIP2 SIP3 SIP4 Cable ABC Cable

SIP-1 – self supporting wire with Al cores, with insulation from light-stabilized cross-linked PE,
neutral messenger non-insulated core from Al alloy.
SIP-2 – the same.
SIP-3 – protected self supporting wire, with conducting core from Al alloy with insulation from lightstabilized cross-linked PE.
SIP-4 – protected self supporting wire, without currier element, with Al conducting cores with insulation from light-stabilized cross-linked PE.

CONSTRUCTION
1. CONDUCTING CORE – Al round core  for all cross-section the core is compacted multiwire, the quantity of wire in phase core. Outer diameter of conducting core and its electrical resistance shown in bellow table:

 
2. NEUTRAL MESSENGING CORE – form Al alloy, round core, stranded from round wires,
compacted. Nominal cross-sections, number of wires in the core, outer diameter of core, its burst capacity and electrical resistance are specified in the bellow table:

 
3. INSULATION – in SIP-1 the neutral core is not insulated. In other conductors the insulation made from light-stabilized cross-linked PE. Insulated phase cores have the distinctive coloring. Insulation thickness is shown in the following table:
