Webb signal/control cables are multi-conductor cables used in automation and instrumentation applications. They are designed to be flexible to enable hassle-free routing and cabling at any location. The inner structure consists of electrolytic stranded copper conductors insulated in a polypropylene compound. These are then wrapped in an aluminium screening to prevent electrical interference, and further covered with a PVC sheath.

Specifications:

• Conductor: stranded electrolytic copper.
• Insulation: polypropylene compound.
• Screen: Aluminium foiled and PET tape.
• Tinned copper drain wire (7 strands x 0.20mm).
• Outer sheath: PVC compound.
• Outer sheath colour: Grey.
• Operating voltage (U₀/U): 300 V.
• Bending radius: 10 x D.
• Operating temperature: -30 °C to +70 °C.

Stranding: in layers.
