Solid conductor 1 and 2-core jumper wires specifically for use with Krone and other IDC systems.
These have a hardened grade of PVC for their outer insulation, specifically designed for use in larger wiring frames, where the wires may be subject to more mechanical stress, and where a harder jacket is desirable to reduce the risk of chafing. All versions conform to BT CW1423 specification (which directly supercedes CW1257, which specified the now obsolete “irradiated cross-linked PVC”).
