ZR Flame Retardant Armoured Copper Control Cables 4x10mm² Cross Section For Fixed Laying
KVV22 steel armored control cables (KVVP2-22 copper tape shielded steel tape armored control cable) are designed for fixed installation in chambers, ducts, pipes, and direct burial applications. These cables are used for signaling control, monitoring, and protection circuit lines in electrical instruments and power distribution units.
KVV32 steel wire armored control cables are laid in fixed locations including indoors, cable trenches, pipelines, direct burial, and shafts. They are used for signal transmission, control and measurement of monitoring circuits, protection circuits, and electrical instruments in power distribution systems.

The control cable features copper cores with the following configurations:
- Nominal cross section 2.5mm² and below: 2–61 cores
- 4–6mm²: 2–14 cores
- 10mm²: 2–10 cores
Control cables used in computer systems typically utilize polyvinyl chloride, polyethylene, cross-linked polyethylene, and fluoroplastic insulation products.
