(TU 16-705.500-2006 used instead of TU 16.К71-268-98 and TU 16.К71- 272-98)


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.

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
