PVC Insulated Jumper Wires to CW 1109, CW 1257 & CW 1423

Application

The jumper wires are used for interconnection between terminal blocks at main distribution frames (MDF), cross

connection cabinets (CCP) and distribution frames or boxes.

Standards

CW 1109 (PVC T2)

CW 1257 (Cross linked PVC)

CW 1423 (PVC BT M154)

Construction

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
