WHAT ARE CONTROL CABLES LIKE?

CONTROL CABLES

The control cables are recommended for control circuits, signaling of electrical equipment, structured cabling, machine connections, button panels, power supply, microprocessed systems, in automation of substations, generating plants, industrial and chemical areas and control of electrical systems in general. Recommended for fixed or mobile installations (light services).

Control cables can be manufactured with or without shielding, when with shielding they can be made from aluminized electrostatic tape, tinned or bare copper mesh, copper tape, steel tape, steel mesh.

Control cables up to a gauge of 1.0mm² have an insulation voltage of 500V, from 1.5 to 10.0mm² have an insulation voltage of 1000V.

The control cables are  made up of bare electrolytic copper conductors, class 5 flexible stranding in accordance with NBR NM 280, insulation in thermoplastic compound based on polyvinyl chloride (PVC/A) 70ºC, intermediate layer for shielding in copper mesh , shielding when requested, separator in polyester tape, and cover in thermoplastic compound based on polyvinyl chloride (PVC/ST1) on the black color or other color when requested by the customer. These characteristics are in accordance with NBR 7289.

We can manufacture control cables in other configurations and characteristics upon request.
