What is harsh environment wire?

Defined by its name, harsh environment wire is cable suitable for less than friendly environments. Typically used as hook up wire, each reel performs to an optimum level within harsher areas. High temperature can be a massive threat in terms of electronics, causing all kinds of health and safety risks. These RS PRO cables provide excellent resistance to such problems.

Where is harsh environment wire used?

Any electronic devices situated within harsh environments would benefit from this type of wire. Laboratories would be be a good example, as they are areas which could have toxic and potentially damaging gasses that interfere with wires. As as example, some areas using these cables would be:

• Construction sites
• Car engines
• Aeroplanes
• Petrol stations


The maximum working voltage on these cables is 600Vac
