Product Specification

7/0.2mm duct-burial def-stan type signal cable (unscreened) is designed for inter-connecting sensors, control panels, alarm systems etc. They are widely used within the security industry where a more robust cable is  required. 

Because of the mechanical design of these 7/0.2mm PE cables they should not be used for direct connection to mains power supplies.

Signal cables have small conductor sizes and are generally used for wiring between components or within electronic equipment.

Suitable for installation indoors or outdoors in dry or wet areas, thin version (duct grade) recommended for ducted installations and thick version (double insulated) for heavy duty or direct burial applications.


7-2-8A PE: 8 Core Thin (duct grade)
7-2-12A PE: 12 Core Thin (duct grade)
7-2-8A PE/PVC: 8 Core Thick (direct burial)
7-2-12A PE/PVC: 12 Core Thick (direct burial)
