Telephone Cables

 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
