Unarmoured 250V Instrumentation

Unarmoured 250V Instrumentation

Manufactured in both pairs and triples these 150/250V instrumentation cables provide collective or individual screening through the use of metallic foils and drain wires. The latest SW4 Low Smoke Halogen Free sheathing compounds ensure that in the event of a fire the cables offer excellent protection to both people and property by not emitting toxic or corrosive gases whilst keeping emergency circuits operating.

Core Identification

Pairs :  Each pair black, white and numbered
Triples : Each triple black, white, red and numbered
(Alternative colour codes are available)
