• CW 1109 (PVC T2)
• CW 1257 (Cross linked PVC)
• CW 1423 (PVC BT M154)
Conductors
Solid annealed tinned copper 0.32/0.4/0.5/0.6/0.8/1.0mm as per class 1 of BS 6360/IEC 60228
Insulation
PVC Type 2 to BS 6746 (CW 1109); Cross-linked PVC (CW 1257) & PVC (CW 1423)
Twisted Pairs
For CW 1109 & CW 1257, two insulated conductors are twisted into pairs with varying lays to minimize crosstalk. For CW 1423, one, two, three, four or five insulated conductors are twisted together with a right hand lay
